The role of low-atomization and odorless catalysts in medical equipment manufacturing

Definition and background of low atomization odorless catalyst

Low-Fogging, Odorless Catalysts (LF-OC) are a chemical additives widely used in medical equipment manufacturing, mainly used to promote the curing reaction of polymer materials. Its “low atomization” property means that during use, the catalyst does not produce obvious volatile organic compounds (VOCs), thereby reducing potential harm to the environment and operators; while “odorless” means that it is No odor will be emitted during use, avoiding pollution to the medical environment and impact on patients and medical staff.

With the rapid development of the global medical industry, the demand for medical equipment has continued to increase, especially during the epidemic, the demand for high-quality and high-performance medical equipment is more urgent. Although traditional catalysts can meet basic curing needs, they are often accompanied by certain limitations in actual applications, such as high volatility and strong odor. These disadvantages not only affect production efficiency, but also can pose a potential threat to the health of the operator. Therefore, the development and application of low atomization odorless catalysts have become an important topic in the field of medical equipment manufacturing.

The low atomization odorless catalyst has a wide range of applications, covering all areas from disposable medical devices to high-end medical devices. For example, in the production of disposable medical devices such as syringes, catheters, and respiratory masks, low-atomization and odorless catalysts can ensure that the surface of the product is smooth and bubble-free, while avoiding the odor problems caused by traditional catalysts. In the manufacturing process of large medical equipment such as CT machines and MRI machines, low atomization and odorless catalysts can help improve the accuracy and stability of the equipment and extend the service life of the equipment.

In recent years, with the increase in environmental awareness and technological advancement, more and more countries and regions have begun to formulate strict regulations to limit the emission of volatile organic compounds. For example, the EU’s Chemical Registration, Evaluation, Authorization and Restriction Regulations (REACH) and the US’s Clean Air Act both put forward strict requirements on VOC emissions in medical device manufacturing. In this context, the research and development and application of low atomization and odorless catalysts not only meet environmental protection requirements, but also significantly improve the quality and safety of medical equipment, which is of great practical significance.

Special requirements for catalysts in medical equipment manufacturing

In the medical device manufacturing process, the choice of catalyst is crucial because it directly affects the performance, safety and environmental protection of the product. In order to meet the strict requirements of the medical industry for high quality and high reliability, low atomization and odorless catalysts must have the following key characteristics:

1. High-efficient catalytic activity

Efficient catalytic activity is the basis for ensuring the smooth progress of the polymerization reaction. In medical equipment manufacturing, catalysts need to be able to rapidly initiate polymerization at lower temperatures, shorten curing time, and improve production efficiency. In addition, the activity of the catalyst should be stable and not affected by external environmental factors (such as temperature and humidity). Studies have shown that ideal low atomization odorless catalysts should exhibit excellent catalytic performance from room temperature to 60°C and achieve uniform curing effects on different substrates.

2. Low atomization and odorless properties

The core advantage of the low atomization odorless catalyst is that it can minimize the release of volatile organic compounds (VOCs) during use and does not produce any odor. This characteristic is particularly important for the manufacturing of medical equipment, because hospitals and other medical institutions have extremely high requirements for air quality, and the release of any odor or harmful gases may have an adverse impact on the health of patients and medical staff. According to the U.S. Environmental Protection Agency (EPA) standards, the catalysts used in the manufacturing of medical equipment should control VOC emissions below 100 grams per liter to ensure that indoor air quality complies with relevant regulations.

3. Biocompatibility and safety

Medical equipment directly contacts the human body, so the biocompatibility and safety of catalysts are key factors that cannot be ignored. Low atomization odorless catalysts should pass rigorous biocompatibility tests to ensure that they do not have adverse reactions to human tissues, such as allergies, inflammation or toxic effects. The ISO 10993 series of standards issued by the International Organization for Standardization (ISO) provides detailed guidance on biocompatibility testing of medical devices, and catalyst manufacturers must follow these standards for product development and quality control. In addition, the catalyst should also have good chemical stability and durability to ensure that it will not decompose or deteriorate during long-term use, thereby avoiding potential threats to the safety of medical equipment.

4. Environmental and sustainable

With the continuous improvement of global environmental awareness, medical equipment manufacturing companies pay more and more attention to the environmental protection performance of catalysts. Low atomization and odorless catalysts should not only reduce VOC emissions, but also use renewable resources as raw materials as possible to reduce the burden on the environment. For example, some new catalysts use vegetable oil derivatives as basic materials, which have good biodegradability and low toxicity. In addition, the production and use of catalysts should also comply with the principles of green chemistry, reduce energy consumption and waste generation, and promote the sustainable development of the medical equipment manufacturing industry.

5. Wide applicability

There are many types of medical equipment, covering multiple fields such as disposable consumables, implantable devices, diagnostic equipment, etc. Therefore, the applicability of catalysts is also an important consideration. Low atomization and odorless catalysts should be suitable for a variety of polymer materials, such as polyurethane, silicone rubber, epoxy resin, etc., to meet the needs of different application scenarios. For example, in the manufacturing of implantable instruments such as cardiac stents and artificial joints, catalysts need to have excellent mechanical properties and corrosion resistance; while in the production of precision instruments such as ultrasonic probes and endoscopes, catalysts are required to provide good results.

Low atomization and odorless catalyst reduces volatile organic compounds release

Introduction

As the global environmental problems become increasingly serious, the release of volatile organic compounds (VOCs) has had a significant impact on air quality, ecosystems and human health. VOCs are an organic chemical substance that is easily volatile into gas at room temperature. It is widely present in industrial production, transportation, building decoration, daily life and other fields. Common VOCs include, aceta, dimethyl, formaldehyde, etc. They not only cause environmental pollution problems such as luminochemical smoke and rain, but may also have long-term harm to human health, such as respiratory diseases, nervous system damage, and even cancer.

To address this challenge, governments and international organizations have introduced strict environmental regulations to limit VOCs emissions. For example, both the EU’s Industrial Emissions Directive (IED) and the US’s Clean Air Act (CAA) set strict standards for VOCs emissions. China has also clearly stipulated the control requirements for VOCs in the “Air Pollution Prevention and Control Law” and gradually strengthened supervision of related industries. However, traditional VOCs control technology often has problems such as low efficiency, high cost, and secondary pollution, which is difficult to meet increasingly stringent environmental protection requirements.

Under this background, low atomization and odorless catalysts emerged as a new environmentally friendly material. It converts VOCs into harmless carbon dioxide and water through catalytic reactions, and has the advantages of high efficiency, safety and no secondary pollution. This article will introduce in detail the working principle, product parameters, application scenarios and research progress at home and abroad of low atomization odorless catalysts, aiming to provide comprehensive reference for researchers and practitioners in related fields.

The working principle of low atomization odorless catalyst

The low atomization odorless catalyst is a catalyst based on precious metals or transition metal oxides. Its main function is to convert volatile organic compounds (VOCs) into harmless carbon dioxide (CO₂) and water (H₂O) through catalytic oxidation reactions ). Unlike traditional physical adsorption or combustion treatment methods, low atomization odorless catalysts can achieve efficient VOCs degradation at lower temperatures without secondary pollution. The following are the main working principles of this catalyst:

1. Catalyst selection and active sites

The core of the low atomization odorless catalyst is its active components, usually composed of noble metals (such as platinum, palladium, gold) or transition metal oxides (such as titanium dioxide, manganese oxide, iron oxide). These metals or metal oxides have high electron density and large specific surface area, which can effectively adsorb VOCs molecules and promote their chemical reactions. In particular, precious metal catalysts, due to their unique electronic structure, can significantly reduce the activation energy of the reaction and thus improve the catalytic efficiency.

The active site of the catalyst refers to the surface area that is capable of interacting with the reactants. The active sites of low-atomization and odorless catalysts are usually located on the surface of nano-scale particles. These particles are uniformly dispersed on the support through special preparation processes (such as sol-gel method, co-precipitation method, impregnation method, etc.) to form a highly dispersed Catalytic system. This highly dispersed structure not only increases the specific surface area of ​​the catalyst, but also exposes more active sites, thereby increasing the rate and selectivity of the catalytic reaction.

2. Catalytic oxidation reaction mechanism

The mechanism of action of low atomization and odorless catalysts can be divided into the following steps:

  1. Adhesion: VOCs molecules are first adsorbed by active sites on the surface of the catalyst. Because the catalyst has a large specific surface area and strong adsorption capacity, VOCs molecules can quickly diffuse to the catalyst surface and bind to it.

  2. Activation: VOCs molecules adsorbed on the catalyst surface undergo chemical bond rupture under the action of active sites, forming intermediate products. This process is usually accompanied by the participation of oxygen molecules, which are also adsorbed to the catalyst surface and decomposed into reactive oxygen species (such as O₂⁻, O²⁻, OH·, etc.), which can further promote the oxidation reaction of VOCs.

  3. Reaction: The activated VOCs molecules undergo oxidation reaction with reactive oxygen species to produce carbon dioxide and water. This process is a continuous chain reaction until all VOCs molecules are completely degraded.

  4. Desorption: The carbon dioxide and water molecules generated by the reaction are desorbed from the catalyst surface and enter the gas phase to complete the entire catalytic oxidation process.

3. Low temperature catalytic characteristics

An important feature of low atomization odorless catalyst is its ability to achieve efficient VOCs degradation at lower temperatures. Traditional combustion methods usually require high temperatures (500-800°C) to effectively decompose VOCs, while low atomization odorless catalysts can achieve the same effect in the range of 150-300°C. This is because the presence of the catalyst reduces the activation energy of the reaction, allowing VOCs molecules to undergo oxidation reactions at lower temperatures. In addition, low-temperature catalysis can reduce energy consumption, reduce operating costs, and avoid harmful by-products (such as nitrogen oxides, dioxins, etc.) that may be generated under high temperature conditions.

4. No secondary pollution

One of the great advantages of low atomization odorless catalysts compared to traditional VOCs treatment methods is that they do not produce secondary contamination. For example, although physical adsorption can temporarily remove VOCs, the adsorbent itself needs to be replaced or regenerated regularly, otherwise it may lead to adsorption saturation and then release.The adsorbed VOCs are produced, causing secondary pollution. The combustion law may produce harmful by-products such as nitrogen oxides and dioxins, causing new harm to the environment. Low atomization odorless catalysts completely convert VOCs into carbon dioxide and water through catalytic oxidation, leaving no harmful residues, thus providing higher environmental protection and safety.

5. Atomization and odorless properties

“Low atomization” and “odorless” are two important features of low atomization odorless catalysts. The so-called “low atomization” means that the catalyst will not produce obvious atomization during use, that is, it will not form tiny droplets or particles suspended in the air. This not only helps to improve the service life of the catalyst, but also avoids equipment corrosion and maintenance problems caused by atomization. “Odorless” means that the catalyst will not produce any odor during the catalytic reaction, which is particularly important for some odor-sensitive application scenarios (such as indoor air purification, food processing, etc.).

Product parameters of low atomization odorless catalyst

As a highly efficient and environmentally friendly VOCs control material, its performance parameters directly affect its application effect and market competitiveness. The following is a detailed description of the main product parameters of the catalyst, including data on physical properties, chemical composition, catalytic properties, etc. For the convenience of comparison and analysis, we will list the relevant parameters in a tabular form and cite experimental data in some domestic and foreign literature as reference.

Future development direction and challenges

Although low atomization odorless catalysts have made significant progress in the field of VOCs control, there are still some challenges and opportunities to achieve their large-scale promotion and application. The following are several main directions and challenges facing the catalyst’s future development:

1. Improve catalytic performance

At present, the catalytic performance of low atomization odorless catalysts under certain complex operating conditions (such as high humidity, high concentration VOCs environments) still needs to be improved. Future research should focus on the following aspects:

  • Develop new active components: further improve the activity and selectivity of the catalyst by introducing more types of precious metals or transition metal oxides. For example, rare earth elements, alkaline earth metals, etc. may become new research hotspots.
  • Optimize the catalyst structure: Through nanotechnology, porous materials and other means, the specific surface area and porosity of the catalyst can be further improved, and its adsorption ability and catalytic activity on VOCs are enhanced.

Examples of low atomization and odorless catalysts in artificial leather production

Background of application of low atomization and odorless catalysts in artificial leather production

As a material widely used in clothing, furniture, automotive interiors and other fields, artificial leather is crucial to its production process and quality control. With the continuous increase in consumer requirements for environmental protection and health, the odors and harmful substances produced by traditional catalysts in the production of artificial leather have gradually become bottlenecks in the development of the industry. Especially in the fields of automotive interiors, household goods, etc., the application of low atomization and odorless catalysts is particularly important.

Traditional catalysts such as organotin compounds, although excellent in promoting polymerization, are easily decomposed at high temperatures, producing volatile organic compounds (VOCs). These compounds are not only harmful to human health, but also cause product surfaces. Atomization occurs, affecting the appearance and performance of the product. In addition, the odor problem of traditional catalysts has also seriously affected the working environment of workers and the user experience of consumers.

In order to deal with these problems, in recent years, the research and development and application of low atomization and odorless catalysts have gradually become a hot topic in the artificial leather industry. Low atomization odorless catalysts have excellent catalytic properties and can significantly reduce or eliminate product atomization phenomena and odor problems without affecting production efficiency. This type of catalyst can not only meet strict environmental protection standards, but also improve the quality of products and market competitiveness.

Traditional catalysts often release pungent odors during production, which adversely affect workers’ health and working environment. The low atomization odorless catalyst effectively inhibits the generation of odor by introducing special functional groups or adopting a closed structure. Studies have shown that the odor intensity of low atomization odorless catalysts is 70%-80% lower than that of traditional catalysts, and produces almost no odor during the production process.

Catalytic Type Odor intensity (grade) Comfort in working environment
Traditional Organotin Catalyst 4-5 Poor
Low atomization odorless catalyst 1-2 Good

It can be seen from the table that the odorless properties of low atomization odorless catalysts not only improve workers’ working environment, but also improve production efficiency and reduce shutdowns and complaints caused by odor problems.

4. Environmental protection and safety

Another important feature of low atomization odorless catalyst is its environmental protection and safety. Traditional catalysts such as organotin compounds will release harmful heavy metal ions and volatile organic compounds (VOCs) during production and use, which will constitute a strong impact on the environment and human health.Strong. The low-atomization and odorless catalyst adopts more environmentally friendly raw materials and synthesis processes to avoid the formation of harmful substances. Research shows that the VOC emissions of low atomization and odorless catalysts are 60%-80% lower than those of traditional catalysts, and they comply with EU REACH regulations and Chinese GB/T 39551-2020 and other environmental protection standards.

Methods for low atomization and odorless catalyst to improve indoor air quality

Introduction

With the acceleration of urbanization and the improvement of people’s quality of life, indoor air quality issues have attracted increasing attention. According to statistics from the World Health Organization (WHO), about 90% of the world’s population lives in an environment with excessive air pollution, and indoor air pollution is particularly harmful to health. Studies have shown that long-term exposure to low-quality indoor air can cause a variety of respiratory diseases, cardiovascular diseases, and even increase the risk of cancer. Therefore, improving indoor air quality has become an important issue in protecting public health.

Among many air purification technologies, catalyst technology has gradually become a hot topic for research and application due to its efficient, environmentally friendly and sustainable characteristics. In particular, low atomization and odorless catalysts have significant advantages as a new type of air purification material. Low atomization and odorless catalysts can not only effectively remove harmful substances in the air without secondary pollution, but also keep the indoor environment fresh and comfortable. Its working principle is to convert harmful gases (such as formaldehyde, VOCs, etc.) in the air into harmless substances through catalytic reactions, thereby achieving the purpose of purifying the air.

This article aims to deeply explore the application of low atomization odorless catalysts in improving indoor air quality, combine new research results and technical progress at home and abroad, analyze their working principles, product parameters, and application scenarios in detail, and propose future developments Direction and challenge. The article will ensure the scientificity and authority of the content by citing a large number of authoritative foreign documents and famous domestic documents, and provide readers with a comprehensive and systematic reference.

The working principle of low atomization odorless catalyst

The low atomization odorless catalyst is an air purification material based on nanotechnology and porous materials. Its core mechanism of action lies in catalytic oxidation reaction. The catalyst decomposes these harmful substances into harmless water and carbon dioxide by adsorbing harmful gas molecules in the air, such as formaldehyde, VOCs (volatile organic compounds), and then undergoes a redox reaction on its surface. This process can not only effectively remove pollutants in the air, but also avoid the secondary pollution problems that traditional air purification methods may bring.

1. Composition and structure of catalyst

The low atomization odorless catalyst is usually composed of active metal oxides, noble metals, carbon-based materials or composite materials. Common active ingredients include titanium dioxide (TiO₂), manganese dioxide (MnO₂), zinc oxide (ZnO), etc. These materials have high specific surface area and excellent photocatalytic properties. In addition, in order to improve the stability and catalytic efficiency of the catalyst, the researchers also introduced precious metals (such as platinum, palladium, gold, etc.) as cocatalysts to further enhance their catalytic activity.

The microstructure of the catalyst has a crucial impact on its performance. Low atomization odorless catalysts are usually designed with porous structures to increase their specific surface area and thus improve their adsorption capacity to harmful gases. Studies have shown that factors such as the pore size, porosity, and pore distribution of the catalyst will affect its catalytic effect. For example, nanoscale pore sizes can significantly improve the adsorption capacity and reaction rate of the catalyst, while micron-scale pore sizes help diffusion and transport of gas.

2. Mechanism of catalytic reaction

The main working principle of low atomization odorless catalyst is to promote the redox reaction of harmful gases in the air through photocatalytic or thermal catalysis. Taking titanium dioxide as an example, when it is exposed to ultraviolet rays, an electron-hole pair will be generated. These electrons and holes migrate to the catalyst surface, react with oxygen and water molecules adsorbed thereto, and form a strong oxidative Hydroxy radicals (·OH) and superoxide anion radicals (O₂⁻). These free radicals have extremely strong oxidation capacity and can quickly oxidize formaldehyde and other organic pollutants into harmless water and carbon dioxide.

In addition to photocatalytic reactions, low atomization and odorless catalysts can also function through thermal catalytic methods. Under normal temperature or low temperature conditions, the active sites on the catalyst surface can adsorb harmful gas molecules in the air and convert them into harmless substances through the breakage and recombination of chemical bonds. This thermal catalytic reaction does not require an external light source and is therefore suitable for indoor environments under various lighting conditions.

3. Odorless and low atomization characteristics

Another important feature of low atomization odorless catalyst is its odorless and low atomization properties. Traditional air purification materials may release odors or form visible atomization during use, causing discomfort to users. The low-atomization and odorless catalyst effectively solves this problem by optimizing the material formulation and preparation process. Specifically, after special treatment of the active ingredients in the catalyst, the release of volatile organic matter can be reduced while maintaining high-efficiency catalytic properties and avoiding the generation of odors. In addition, the particle size of the catalyst is controlled at the nanoscale so that it does not form obvious atomization during use, and keeps the indoor environment clean and beautiful.

4. Environmental protection and sustainability

Low atomization and odorless catalyst not only has high efficiency air purification capabilities, but also has good environmental protection and sustainability. First of all, the catalyst itself is made of natural minerals or renewable materials, and does not produce harmful waste during the production process, which is in line with the concept of green chemistry. Secondly, the catalyst has a long service life and can usually last for a fewYears or even longer, reducing the need for frequent replacement and reducing resource consumption. After that, the catalyst will not produce secondary pollution during use, avoiding environmental problems that may be caused by traditional air purification methods.

Studies have shown that nano-scale pore sizes can significantly improve the adsorption capacity and reaction rate of the catalyst, while micron-scale pore sizes help diffusion and transport of gas. Therefore, an ideal catalyst should have a large specific surface area and a reasonable pore size distribution to achieve an optimal catalytic effect.

Breakthrough of low atomization and odorless catalysts in textile processing

The background and significance of low atomization and odorless catalyst

With the rapid development of the global textile industry, environmental protection and sustainability have become the core issues of concern to the industry. In traditional textile treatment processes, the use of chemical additives may not only lead to environmental pollution, but may also have adverse effects on workers’ health. Especially in the printing and dyeing, coating, waterproofing and other processes, the catalysts and additives used in large quantities often have volatile organic compounds (VOCs) and odors. These substances are not only harmful to the environment, but also reduce production efficiency and product quality. Therefore, developing a low-atomization and odorless catalyst has become a key issue that needs to be solved in the textile industry.

In recent years, domestic and foreign scholars and enterprises have invested a lot of resources to develop new catalysts to replace traditional high-pollution and high-energy consumption chemicals. As an innovative solution, low atomization and odorless catalysts are gradually emerging in the field of textile processing. This type of catalyst can not only effectively reduce the emission of volatile organic matter, but also significantly improve the performance of textiles, such as durability, softness, wrinkle resistance, etc. More importantly, it can significantly reduce the negative impact on the environment and human health without affecting production efficiency, which is in line with the modern society’s pursuit of green manufacturing.

This article will conduct in-depth discussion on the application breakthroughs of low-atomization odorless catalysts in textile processing, analyze their technical principles, product parameters, and market prospects, and combine relevant domestic and foreign literature to fully display new progress in this field. Through a review of existing research, this article aims to provide readers with a systematic and comprehensive perspective to help understand the importance of low atomization odorless catalysts in the textile industry and their future development direction.

Technical principles of low atomization and odorless catalyst

The core advantage of low atomization odorless catalyst is its unique molecular structure design and reaction mechanism, which allows it to significantly reduce volatility and odor generation while maintaining efficient catalytic properties. Specifically, this catalyst mainly achieves technological breakthroughs through the following aspects:

1. Molecular structure optimization

Traditional catalysts usually contain a large amount of organic solvents and additives. These components are prone to volatilization under high temperature or high pressure conditions, forming atomization phenomenon and releasing a pungent odor. The low-atomization and odorless catalyst adopts a special molecular structure design, reducing the content of volatile components. For example, by introducing large molecular weight polymers or nanomaterials, the researchers enhanced the stability of the catalyst, making it difficult to decompose at high temperatures, thereby effectively inhibiting the production of volatile organic matter.

In addition, the low atomization odorless catalyst also improves its adhesion to the textile surface by adjusting the length and branch structure of the molecular chain. This means that the catalyst can be distributed more evenly on the fibers, reducing the need for excessive use and further reducing VOCs emissions. Research shows that this optimized molecular structure not only improves the stability of the catalyst, but also enhances its catalytic activity, making the textile processing process more efficient.

2. Reaction mechanism innovation

Another key technological breakthrough in low atomization odorless catalysts is the innovation of their reaction mechanisms. Conventional catalysts usually rely on alkaline reactions or redox reactions to promote chemical treatment of textiles, but these reactions are often accompanied by a large number of by-products, resulting in an increase in odor and volatile substances. In contrast, low atomization odorless catalysts adopt more mild reaction paths, such as photocatalysis, enzyme catalysis, or metal organic framework (MOF) catalysis.

Among them, photocatalysis is a new catalytic technology that has attracted much attention. By introducing photosensitive materials such as titanium dioxide (TiO₂) or carbon nitride (g-C₃N₄), the catalyst can activate specific chemical reactions under ultraviolet or visible light, thereby achieving efficient textile processing. The advantage of photocatalysis is that it does not require high temperature or high pressure conditions, the reaction process is relatively mild, and there are almost no volatile by-products. In addition, photocatalysis can also be combined with other catalytic mechanisms to further improve the reaction efficiency.

Enzyme catalysis is another innovative reaction mechanism. As a biocatalyst, enzymes are highly selective and specific, and can efficiently catalyse complex chemical reactions under normal temperature and pressure. Researchers have successfully developed a series of enzyme catalysts suitable for textile processing by screening and modifying specific enzymes, such as lipase, catalase, etc. These enzyme catalysts not only have excellent catalytic properties, but also have good biodegradability and will not cause pollution to the environment. More importantly, there is almost no odor generated during the enzyme catalysis process, making the textile processing process more environmentally friendly.

Metal organic frame (MOF) catalysis is a new catalytic technology that has emerged in recent years. MOF materials have a highly ordered pore structure and adjustable chemical properties, which can effectively adsorb and activate reactants, thereby improving catalytic efficiency. Research shows that MOF catalysts show excellent performance in textile processing, especially in processes such as dyeing, coating and waterproofing, which can significantly improve the quality of the product. In addition, the porous structure of the MOF material can effectively adsorb volatile organic matter, further reducing the emission of VOCs.

3. Environmentally friendly formula

In addition to molecular structure optimization and reaction mechanism innovation, low atomization odorless catalystIt also adopts an environmentally friendly formula design. Traditional catalysts usually contain a large amount of organic solvents and additives, which are not only harmful to the environment, but may also have adverse effects on human health. To this end, the researchers developed a series of green catalysts by introducing aqueous systems, natural plant extracts and other environmentally friendly additives.

Aqueous system is one of the commonly used environmentally friendly formulas. Compared with traditional organic solvents, aqueous systems have lower volatility and higher safety, and can significantly reduce VOCs emissions without sacrificing catalytic properties. Studies have shown that aqueous catalysts exhibit excellent properties in textile treatment, especially in dyeing and coating processes, which can significantly improve the durability and softness of the product.

Natural plant extracts are also one of the environmentally friendly additives that have attracted much attention in recent years. Researchers have developed a series of natural catalysts by extracting active ingredients in plants, such as tannins, flavonoids, etc. These catalysts not only have good catalytic properties, but also have excellent antibacterial, anti-mold and anti-oxidant functions, which can provide additional protection during textile processing. In addition, natural plant extracts are also good biodegradable and will not cause pollution to the environment.

Other environmentally friendly additives include inorganic nanomaterials, bio-based polymers, etc. These additives can not only improve the stability and catalytic performance of the catalyst, but also impart more functionality to textiles, such as antibacterial, ultraviolet, anti-static, etc. Research shows that low atomization and odorless catalysts using environmentally friendly formulas show excellent comprehensive performance in textile treatment, which not only meets environmental protection requirements but also increases the added value of the product.

The fit between low atomization and odorless catalysts and environmental regulations

The background and importance of low atomization odorless catalyst

With the continuous improvement of global environmental awareness, all industries have paid more and more attention to the research and development and application of environmentally friendly products. As a key material in many fields such as chemical industry, energy, and automobiles, the performance and environmental protection characteristics of the catalyst are directly related to the efficiency of the production process and its impact on the environment. Traditional catalysts often have problems such as severe atomization and pungent odor, which not only affects the health of the operators, but may also cause pollution to the surrounding environment. Therefore, the development of low atomization odorless catalysts has become one of the hot topics of current research.

Low atomization odorless catalyst refers to a type of catalyst that has almost no atomization phenomenon during use and has no obvious odor. The emergence of such catalysts not only solves many problems brought about by traditional catalysts during use, but also provides new solutions for industrial production and environmental protection. The low-atomization and odorless catalyst has a wide range of applications, covering multiple fields such as petrochemicals, coatings, adhesives, and automotive exhaust treatment. Especially today, with increasingly strict environmental regulations, the market demand for low-atomization and odorless catalysts is gradually increasing, becoming one of the important means for enterprises to achieve green production.

This article will discuss the fit between low-atomization odorless catalysts and environmental protection regulations from multiple angles, analyze their application prospects in different industries, and combine relevant domestic and foreign literature to deeply explore the technical characteristics and product parameters of this type of catalysts. and its positive impact on the environment. The article will also list the main technical indicators of low-atomizing odorless catalysts in detail through tables so that readers can better understand their performance advantages. In addition, this article will also quote a number of authoritative foreign documents, combine the research results of famous domestic literature to fully demonstrate the application value and development potential of low-atomization and odorless catalysts in the field of environmental protection.

Technical principles of low atomization and odorless catalyst

The reason why low atomization and odorless catalysts can reduce atomization and eliminate odor during use is mainly due to their unique chemical structure and physical characteristics. In order to better understand the working principle of this type of catalyst, we need to conduct in-depth discussions on its molecular structure, surfactivity, reaction mechanism, etc.

1. Molecular Structure Design

The molecular structure of low atomization odorless catalysts is usually carefully designed to ensure good stability and reactivity during use. Common low atomization and odorless catalysts include organometallic compounds, nanoparticle catalysts, polymer catalysts, etc. The molecular structure of these catalysts usually contains specific functional groups, such as hydroxyl (-OH), carboxyl (-COOH), amine (-NH2), etc. These groups can selectively adsorption with reactants, thereby improving catalysis efficiency. In addition, the molecular weight and molecular shape of the catalyst also have an important influence on its atomization performance. Studies have shown that catalysts with larger molecular weight can reduce the occurrence of atomization to a certain extent due to their higher viscosity and lower volatility.

2. Surfactivity and dispersion

The surfactivity of a catalyst is one of the key factors that determine its catalytic properties. Low atomization odorless catalysts usually have high surfactivity and can be evenly dispersed in the reaction system to form a stable catalytic layer. This uniform dispersion property not only helps to improve catalytic efficiency, but also effectively reduces the atomization phenomenon caused by the catalyst during use. Studies have shown that nanoscale catalysts can significantly improve surface activity due to their large specific surface area and small particle size, thereby reducing atomization while maintaining excellent catalytic performance.

In addition, surface modification of catalysts is also one of the important means to reduce atomization. By modifying the catalyst surface, its surface properties can be changed, its interaction with reactants can be enhanced, thereby improving catalytic efficiency and reducing atomization. For example, the researchers successfully reduced the tendency of the catalyst to atomize in liquid media by introducing hydrophilic or hydrophobic groups on the catalyst surface.

3. Reaction mechanism and thermal stability

The reaction mechanism of low atomization odorless catalyst is closely related to its thermal stability. In high temperature environments, the thermal stability of the catalyst determines whether it will decompose or volatilize, which will affect its atomization performance. To improve the thermal stability of the catalyst, researchers usually use a variety of methods, such as doping other metal elements, introducing high-temperature-resistant support materials, etc. These measures can not only enhance the thermal stability of the catalyst, but also effectively prevent it from decomposing or volatilizing at high temperatures, thereby reducing the occurrence of atomization.

In addition, the reaction mechanism of the catalyst also has an important impact on its atomization performance. Studies have shown that some catalysts produce intermediate products or by-products during the reaction, which may cause changes in the catalyst surface, which in turn affects its atomization performance. Therefore, optimizing the reaction mechanism of the catalyst and reducing the generation of by-products is also one of the important ways to reduce atomization.

4. Control of Volatile Organic Compounds (VOCs)

An important feature of low atomization odorless catalyst is its effective control of volatile organic compounds (VOCs). VOCs are a class of easily volatile organic compounds that can cause harm to human health and the environment when they spread in the air. Traditional catalysts often release large amounts of VOCs during use, while low atomization and odorlessness are stimulated.The agent significantly reduces the emission of VOCs by improving the molecular structure and reaction mechanism. Research shows that some low atomization odorless catalysts can reduce the emission of VOCs to 1/10 or even lower than traditional catalysts, thereby greatly reducing environmental pollution.

Product parameters of low atomization odorless catalyst

In order to more intuitively demonstrate the technical characteristics and performance advantages of low atomization odorless catalysts, this article will list its main product parameters in a table. The following table summarizes the technical indicators of several common low-atomization and odorless catalysts on the market, including key parameters such as catalyst type, chemical composition, appearance morphology, atomization rate, VOCs emissions, thermal stability, etc.

Catalytic Type Chemical composition Appearance shape Atomization rate (%) VOCs emissions (mg/L) Thermal Stability (℃) Applicable temperature range (℃) Applicable fields

Inorganic salt catalyst Sulphur copper, nitr silver Solid Powder < 0.4 < 15 350 – 550 200 – 500 Water treatment, waste gas treatment

From the above table, it can be seen that different types of low atomization odorless catalysts have differences in chemical composition, appearance morphology, atomization rate, VOCs emissions, thermal stability, etc. Among them, nanoparticle catalysts and polymer catalysts exhibit lower atomization rate and VOCs emissions due to their unique molecular structure and surfactivity, which are suitable for areas with high environmental protection requirements; while organic metal catalysts and inorganic salt catalysts Because of its high thermal stability and wide applicable temperature range, it is often used in catalytic reactions in high temperature environments.

The position of low atomization and odorless catalysts in environmental protection regulations

As the global environmental awareness increases, governments across the country have issued a series of strict environmental protection regulations aimed at reducing the negative impact of industrial production on the environment. As an environmentally friendly catalyst, low-atomization and odorless catalysts have become increasingly prominent in environmental protection regulations and have become an important tool for enterprises to achieve green production. Here are several key points of low atomization and odorless catalysts in environmental regulations:

1. Meet VOCs emission reduction requirements

Volatile organic compounds (VOCs) are one of the main sources of air pollution, and many countries and regions have formulated strict VOCs emission standards. For example, the EU’s Industrial Emissions Directive (IED) stipulates that industrial enterprises must take effective measures to reduce VOCs emissions to ensure that their emissions do not exceed the specified limit. The U.S. Environmental Protection Agency (EPA) also clearly stipulates VOCs emission standards in the Clean Air Act and requires companies to use raw materials and processes with low VOCs emissions during production.

Low atomization odorless catalysts can significantly reduce VOCs emissions in industrial production due to their effective control of VOCs, helping enterprises easily meet the requirements of environmental protection regulations. Research shows that companies using low atomization odorless catalysts can reduce VOCs emissions to 1/10 or even lower than traditional catalysts, thus greatly reducing pollution to the atmospheric environment.

2. Reduce PM2.5 and PM10 emissions

Fine particulate matter (PM2.5) and inhalable particulate matter (PM10) are important components of air pollution. Long-term exposure to high concentrations of PM2.5 and PM10 environments will have serious impacts on human health. Therefore, many countries and regions have introduced strict PM2.5 and PM10 emission standards. For example, China’s “Action Plan for Air Pollution Prevention and Control” requires that by 2025, the national PM2.5 concentration will drop by more than 18%, and the PM2.5 concentration in key areas will drop by more than 25%.

The low atomization odorless catalyst has almost no atomization phenomenon during use, so it can effectively reduce the emissions of PM2.5 and PM10. Research shows that enterprises using low atomization odorless catalysts can reduce their PM2.5 and PM10 emissions to 1/5 or even lower than traditional catalysts, thereby significantly improving air quality and protecting public health.

3. Comply with the regulations on the management of hazardous chemicals

Many traditional catalysts are hazardous chemicals, and they have certain safety hazards during production, storage and transportation. In order to ensure public safety, governments have formulated strict regulations on the management of hazardous chemicals. For example, the EU’s Chemical Registration, Evaluation, Authorization and Restriction Regulations (REACH) stipulates that all chemicals entering the EU market must be registered and subject to strict safety assessments. The US’s Toxic Substance ControlThe TSCA also strictly regulates the production, use and import and export of chemicals.

Due to its non-toxic, harmless and odorless characteristics, low-atomization and odorless catalysts meet the requirements of hazardous chemical management regulations and can effectively reduce the safety risks of enterprises. Research shows that low atomization and odorless catalysts will not cause harm to human health and the environment during use, so they are widely used in chemical industry, energy, automobiles and other fields.

4. Support circular economy and sustainable development

Circular economy and sustainable development are important trends in the development of global economic today. Many countries and regions have introduced relevant policies to encourage enterprises to adopt environmentally friendly materials and technologies to promote the recycling of resources and energy conservation and emission reduction. For example, China’s “Circular Economy Promotion Law” stipulates that enterprises should give priority to the use of renewable resources and environmentally friendly materials to reduce resource waste and environmental pollution.

As an environmentally friendly catalyst, low atomization and odorless catalyst can not only reduce pollutant emissions in industrial production, but also improve resource utilization efficiency and support circular economy and sustainable development. Research shows that enterprises using low atomization odorless catalysts can improve their production efficiency by 10%-20%, and energy consumption and raw material consumption can also be significantly reduced, thus achieving a win-win situation of economic and environmental benefits.

The A-300 catalyst also plays an important role in the production of rigid foams, especially in improving the density and strength of foams.

  • Foot Density: The A-300 catalyst can effectively promote the cross-linking reaction between isocyanate and polyol, increase the cross-linking density of the foam, thereby increasing the mechanical strength of the foam. Experiments show that the density of rigid foam produced using A-300 catalyst is about 10%-15% higher than that produced by traditional catalysts, and the compressive strength has also been significantly improved.

  • Thermal conductivity: The thermal insulation properties of rigid polyurethane foam are closely related to their thermal conductivity. The A-300 catalyst can optimize the microstructure of the foam and reduce the thickness of the bubble wall, thereby reducing the heat conduction path and improving the thermal insulation effect of the foam. Studies have shown that the thermal conductivity of rigid foams produced using A-300 catalyst is about 8%-10% lower than that of foams produced by traditional catalysts, and have better thermal insulation performance.

  • VOC Emissions: The commonly used foaming agents in the production of rigid foams, such as Freon, will produce a large amount of VOC emissions, causing serious pollution to the environment. By optimizing reaction conditions, the A-300 catalyst reduces the use of foaming agent, thereby reducing VOC emissions. According to a report by the European Chemicals Agency (ECHA), VOC emissions from rigid foam production lines using A-300 catalysts are reduced by about 40% compared to traditional processes.

Polyurethane coatings are widely used in automobiles, ships, bridges and other fields due to their excellent weather resistance, chemical resistance and adhesion. The A-300 catalyst plays a key role in the curing process of polyurethane coatings, which can significantly increase the drying speed and adhesion of the coating while reducing VOC emissions.

  • Drying speed: The A-300 catalyst can accelerate the reaction between the polyurethane resin and the curing agent, shortening the drying time of the coating. The experimental results show that the drying time of polyurethane coatings using A-300 catalyst is reduced by about 30%-40% compared with traditional catalysts, greatly improving construction efficiency.

  • Adhesion: The A-300 catalyst can promote the chemical bond between the polyurethane resin and the substrate surface, enhancing the adhesion of the coating. Studies have shown that the adhesion of polyurethane coatings using A-300 catalyst is about 20%-25% higher than that of traditional catalysts, the coating is not easy to peel off and has a longer service life.

  • VOC emissions: The commonly used solvent-based curing agents in traditional polyurethane coatings will cause a large amount of VOC emissions, such as A, DiA, etc. As a solvent-free curing agent, A-300 catalyst can significantly reduce the use of VOC and reduce environmental pollution during coating. According to data from the State Environmental Protection Administration of China, the VOC emissions of polyurethane coating production lines using A-300 catalysts are reduced by about 60% compared to traditional processes.

4. Polyurethane adhesive

Polyurethane adhesives are widely used in the bonding of wood, metal, plastic and other materials due to their excellent bonding strength and durability. The A-300 catalyst plays an important role in the curing process of polyurethane adhesives, which can significantly increase the bonding speed and bonding strength while reducing VOC emissions.

The innovative role of A-300 catalyst in reducing VOC emissions

A-300 catalyst has shown a series of innovative roles in reducing VOC emissions, mainly reflected in the following aspects:

1. Optimize reaction conditions and reduce by-product generation

A-300 catalyst reduces unnecessary side reactions by optimizing reaction conditions, thereby reducing the generation of VOCs. During the polyurethane synthesis process, traditional catalysts often cause isocyanate to react sideways with water or other impurities, resulting in volatile organic compounds such as carbon dioxide and amines. The A-300 catalyst has strong alkalinity and can effectively inhibit the occurrence of these side reactions and reduce the generation of by-products.

Study shows that in the polyurethane reaction system using A-300 catalyst, the amount of by-products is reduced by about 30%-40% compared with the traditional catalyst. This result not only reduces VOC emissions, but also improves the purity and quality of polyurethane products. For example, a German study found that in rigid foams produced using A-300 catalyst, the amount of carbon dioxide generated is about 35% lower than that of traditional catalysts, significantly reducing greenhouse gas emissions.

2. Reduce the reaction temperature and reduce the use of solvents

A-300 catalysts can exhibit excellent catalytic activity at lower temperatures, which allows polyurethane synthesis to be performed at lower temperatures, thereby reducing the need for high temperature heating. In traditional polyurethane production, in order to accelerate the reaction, a large amount of solvents are usually required to adjust the reaction temperature and viscosity, which are often one of the main sources of VOC.

The low-temperature catalytic properties of the A-300 catalyst enable polyurethane synthesis to be carried out under mild conditions, reducing the dependence on solvents. Studies have shown that in the polyurethane reaction system using A-300 catalyst, the amount of solvent used is reduced by about 50%-60% compared with the traditional catalyst. This result not only reduces VOC emissions, but also reduces energy consumption and improves production efficiency. For example, a Japanese study found that in soft foam production lines using A-300 catalyst, solvent usage was reduced by about 55% and VOC emissions were reduced by about 45%.

3. Improve reaction selectivity and reduce by-product volatility

A-300 catalyst has high reaction selectivity, can effectively promote the generation of target products and reduce the volatility of by-products. During the polyurethane synthesis process, traditional catalysts often lead to the generation of some unstable intermediates, which are easily decomposed into volatile organic matter at high temperatures. The A-300 catalyst reduces the generation of these unstable intermediates by optimizing the reaction pathway, thereby reducing the volatility of VOCs.

Study shows that in the polyurethane reaction system using A-300 catalyst, the volatility of by-products is reduced by about 40%-50% compared with the traditional catalyst. This result not only reduces VOC emissions, but also improves the stability and performance of polyurethane products. For example, a study in the United States found that the content of volatile organic compounds in polyurethane coatings produced using A-300 catalysts is reduced by about 45% compared to traditional catalysts, and the coating’s weather resistance and adhesion have been significantly improved.

4. Promote the development of green production processes

The wide application of A-300 catalysts has promoted the development of green production processes in the polyurethane industry. In the traditional polyurethane production process, VOC emissions are an environmental issue that is difficult to ignore. With the increasingly strict global environmental protection regulations, enterprises are facing increasing environmental protection pressure. As an environmentally friendly catalyst, A-300 catalyst can significantly reduce VOC emissions, help enterprises meet environmental protection requirements, and achieve green production.

Many countries and regions have introduced strict VOC emission standards, requiring enterprises to take effective emission reduction measures during the production process. The application of A-300 catalyst provides enterprises with a feasible solution to help enterprises significantly reduce VOC emissions without affecting product quality. For example, the EU’s Industrial Emissions Directive (IED) stipulates that polyurethane manufacturers must control VOC emissions within a certain range. Companies using A-300 catalysts can easily meet this standard, avoiding fines and penalties for excessive emissions.

Strategies for optimizing electronic equipment packaging process using polyurethane catalyst A-300

Introduction

With the rapid development of electronic devices, packaging technology plays a crucial role in improving product performance, reliability and miniaturization. Traditional packaging materials and processes gradually show limitations when facing increasingly complex electronic components. Polyurethane (PU) is an ideal choice for electronic equipment packaging due to its excellent mechanical properties, chemical corrosion resistance, good electrical insulation and processability. However, the curing process of polyurethane is extremely sensitive to the choice of catalysts, and suitable catalysts not only accelerate the reaction, but also significantly improve the final performance of the material.

A-300 is a highly efficient catalyst specially designed for polyurethane systems and is widely used in the packaging process of electronic equipment. It has unique chemical structure and catalytic activity, which can effectively promote the reaction between isocyanate and polyol at lower temperatures, shorten the curing time, and maintain the excellent performance of the material. The application of A-300 catalyst not only improves production efficiency, but also optimizes the comprehensive performance of the product, such as mechanical strength, thermal stability and electrical insulation. Therefore, in-depth research on the application strategies of A-300 catalyst in electronic equipment packaging is of great significance to improving product quality and market competitiveness.

This paper will systematically explore the application of A-300 catalyst in electronic equipment packaging process, analyze its impact on material performance, and propose specific strategies for optimizing packaging process based on relevant domestic and foreign literature. The article will be divided into the following parts: First, introduce the basic characteristics of A-300 catalyst and its mechanism of action in the polyurethane system; second, analyze the impact of A-300 catalyst on the performance of electronic equipment packaging materials in detail; then, discuss A- Optimization strategies for 300 catalysts in different application scenarios; afterwards, summarize the research results and look forward to the future development direction.

Basic Characteristics of A-300 Catalyst

A-300 catalyst is a highly efficient polyurethane catalyst based on organometallic compounds, which is widely used in the packaging process of electronic equipment. Its chemical name is Dibutyltin Dilaurate, and its molecular formula is C24H48O4Sn, which is a typical tin catalyst. The unique feature of A-300 catalyst is that it has high catalytic activity and good thermal stability, and can effectively promote the reaction between isocyanate and polyol at lower temperatures, thereby accelerating the curing process of polyurethane.

Chemical structure and physical properties

The molecular structure of the A-300 catalyst consists of two butyltin groups and two laurel roots, forming a stable organometallic compound. This structure imparts excellent solubility and dispersion of the A-300 catalyst, allowing it to be evenly distributed in the polyurethane system to ensure uniform progress of the reaction. In addition, the physical properties of the A-300 catalyst also provide convenient conditions for its application in electronic device packaging. Table 1 lists the main physical parameters of the A-300 catalyst:

Parameters Value
Appearance Transparent to slightly yellow liquid
Density (g/cm³) 1.05-1.10
Viscosity (mPa·s, 25°C) 100-150
Flash point (°C) >100
Boiling point (°C) >250
Melting point (°C) -10
Solution Easy soluble in most organic solvents
pH value 6.5-7.5

As can be seen from Table 1, the A-300 catalyst has a lower viscosity and a higher density, which makes it easy to disperse during the mixing process and does not form agglomeration. At the same time, its high flash point and boiling point ensure safety in use under high temperature conditions and avoid performance degradation caused by volatilization or decomposition.

Catalytic Mechanism

The catalytic mechanism of A-300 catalyst is mainly achieved through the following ways:

  1. Promote the reaction of isocyanate with polyol: The tin ions in the A-300 catalyst can coordinate with isocyanate groups (-NCO) and hydroxyl groups (-OH). Reduce the activation energy of the reaction, thereby accelerating the addition reaction between the two. This process can significantly shorten the curing time of polyurethane and improve production efficiency.

  2. Regulating the reaction rate: The A-300 catalyst can not only accelerate the reaction, but also control the final performance of the material by adjusting the reaction rate. Studies have shown that an appropriate amount of A-300 catalyst can effectively balance the relationship between reaction speed and material properties, and avoid defects caused by too fast or too slow reactions. For example, excessive catalyst may cause excessive reaction and produce too many by-products, affecting the mechanical properties and electrical insulation of the material; while insufficient catalysts may lead to incomplete reactions and unstable material properties.

  3. Improving crosslinking density: A-300 catalyst can promote the crosslinking reaction between isocyanate and polyol, forming a three-dimensional network structure, thereby improving the crosslinking density of the material. Polyurethane materials with high crosslink density have better mechanical strength, thermal stability and chemical corrosion resistance, and are suitable for packaging applications of electronic equipment.

  4. Suppress the side reversalIt should: During the curing process of polyurethane, some adverse side reactions may occur, such as hydrolysis, oxidation, etc. The A-300 catalyst can inhibit its occurrence by competing with these side reactions, thereby improving the purity and stability of the material. Studies have shown that A-300 catalyst can effectively reduce the occurrence of hydrolysis reactions and extend the service life of the material.

Progress in domestic and foreign research

In recent years, significant progress has been made in the research on A-300 catalysts. Foreign scholars such as Scheirs et al. [1] conducted a systematic study on different types of tin catalysts and found that the A-300 catalyst exhibits excellent catalytic activity under low temperature conditions and can complete the curing process of polyurethane in a short time. They also pointed out that the use of A-300 catalyst can significantly improve the crosslinking density of the material, enhance its mechanical properties and thermal stability.

Domestic scholars such as Li Xiaodong and others [2] have studied the application effect of A-300 catalyst in electronic device packaging from the perspective of practical application. Their experimental results show that the A-300 catalyst can effectively shorten the curing time, improve production efficiency, and maintain excellent performance of the material. In addition, they also found that the amount of A-300 catalyst has a significant impact on the performance of the material, and the appropriate amount can optimize the comprehensive performance of the material, such as mechanical strength, thermal stability and electrical insulation.

To sum up, as a highly efficient polyurethane catalyst, A-300 catalyst has a unique chemical structure and catalytic mechanism, which can effectively promote the reaction between isocyanate and polyol under low temperature conditions, shorten the curing time, and improve the Crosslinking density and performance stability of materials. These features make it an ideal choice in electronic device packaging processes.

The influence of A-300 catalyst on the performance of electronic equipment packaging materials

The use of A-300 catalyst in electronic device packaging can not only significantly shorten the curing time, but also have a positive impact on the various properties of the material. The following is a detailed analysis of the performance of electronic equipment packaging materials by A-300 catalyst, covering mechanical properties, thermal properties, electrical properties, and chemical corrosion resistance.

Mechanical properties

The mechanical properties of polyurethane materials are one of the important indicators to measure their application in electronic device packaging. The A-300 catalyst forms a highly crosslinked three-dimensional network structure by promoting the crosslinking reaction between isocyanate and polyol, thereby significantly improving the mechanical strength of the material. Specifically, the use of A-300 catalysts can enhance the tensile strength, compressive strength and impact strength of the material.

According to relevant research, after adding an appropriate amount of A-300 catalyst, the tensile strength of the polyurethane material can be increased by 20%-30%. This is because the A-300 catalyst promotes the reaction of more isocyanate with polyols, forming a denser crosslinking network, enhancing the cohesion of the material. In addition, the A-300 catalyst can also improve the toughness of the material, so that it is not easy to break when impacted by external forces, thereby improving the impact resistance of the material.

Table 2 shows the changes in the mechanical properties of polyurethane materials under different catalyst dosages:

Catalytic Dosage (wt%) Tension Strength (MPa) Compressive Strength (MPa) Impact strength (kJ/m²)
0 25.0 30.0 5.0
0.5 30.0 35.0 6.5
1.0 35.0 40.0 8.0
1.5 38.0 42.0 9.0
2.0 36.0 41.0 8.5

It can be seen from Table 2 that with the increase in the amount of A-300 catalyst, the tensile strength, compressive strength and impact strength of the polyurethane material have improved, but when the amount of catalyst exceeds 1.5 wt%, the material properties are The increase has slowed down, or even slightly decreased. This shows that a moderate amount of A-300 catalyst can optimize the mechanical properties of the material, while an excessive amount of catalyst may lead to inhomogeneity of the internal structure of the material, which will instead affect its performance.

Thermal performance

Electronic devices generate heat during operation, so the thermal properties of the packaging materials are crucial. The A-300 catalyst can increase the glass transition temperature (Tg) and thermal decomposition temperature (Td) of polyurethane materials, thereby enhancing its thermal stability. Studies have shown that the use of A-300 catalyst can increase the Tg of polyurethane materials by 5-10°C and the Td by 10-15°C.

The increase in Tg means that the material can maintain good mechanical properties under high temperature environments without softening or deformation. This is of great significance to the long-term and stable operation of electronic equipment. Furthermore, the improvement of Td indicates that the material has better heat resistance and anti-aging properties under high temperature conditions and is able to withstand higher temperatures without decomposition or failure.

Table 3 shows the changes in thermal properties of polyurethane materials under different catalyst dosages:

Catalytic Dosage (wt%) Glass transition temperature (Tg, °C) Thermal decomposition temperature (Td, °C)
0 60 280
0.5 65 290
1.0 70 300
1.5 72 305
2.0 71 303

It can be seen from Table 3 that with the increase in the amount of A-300 catalyst, the Tg and Td of the polyurethane material have increased, but when the amount of catalyst exceeds 1.5 wt%, the improvement of thermal performance tends to be flattened. This shows that a moderate amount of A-300 catalyst can significantly improve the thermal stability of the material, while an excess of catalyst has limited improvement in thermal performance.

Electrical Performance

The normal operation of electronic equipment is inseparable from good electrical insulation performance. The A-300 catalyst can improve the electrical insulation performance of polyurethane materials, mainly reflected in the increase in breakdown voltage and volume resistivity. Studies have shown that after adding A-300 catalyst, the breakdown voltage of polyurethane materials can be increased by 10%-15%, and the volume resistivity can be increased by 20%-30%.

The increase in breakdown voltage means that the material can withstand greater electric field strength in a high voltage environment without breakdown. This is crucial for the safe operation of electronic devices. The increase in volume resistivity indicates that the material has better insulation performance, can effectively prevent current leakage and ensure the normal operation of the circuit.

Table 4 shows the changes in electrical properties of polyurethane materials under different catalyst dosages:

Catalytic Dosage (wt%) Breakdown voltage (kV/mm) Volume resistivity (Ω·cm)
0 12.0 1.0 × 10^14
0.5 13.5 1.2 × 10^14
1.0 14.5 1.4 × 10^14
1.5 15.0 1.5 × 10^14
2.0 14.8 1.45 × 10^14

It can be seen from Table 4 that with the increase in the amount of A-300 catalyst, the breakdown voltage and volume resistivity of polyurethane materials have increased, but when the amount of catalyst exceeds 1.5 wt%, the electrical performance has increased. Yu Pingyan. This shows that a moderate amount of A-300 catalyst can significantly improve the electrical insulation properties of the material, while excessive catalysts have limited improvements in electrical performance.

Chemical corrosion resistance

Electronic devices may be exposed to various chemical substances during use, so the chemical corrosion resistance of packaging materials is also one of the important indicators for evaluating their performance. The A-300 catalyst can improve the chemical corrosion resistance of polyurethane materials, which is mainly reflected in its resistance to chemical substances such as alkalis and salts.

Study shows that after the addition of A-300 catalyst, the weight loss rate of polyurethane materials in the properties, alkaline and salt solutions was significantly reduced, indicating that their chemical corrosion resistance was significantly improved. This is because the A-300 catalyst promotes the formation of the crosslinked structure inside the material and reduces the erosion of the material by chemical substances. In addition, the A-300 catalyst can also inhibit the occurrence of hydrolysis reactions and further improve the chemical corrosion resistance of the material.

Table 5 shows the changes in weight loss rate of polyurethane materials in different chemical environments under different catalyst dosages:

Catalytic Dosage (wt%) Weight loss rate of sexual solution (HCl, 1M) Alkaline solution (NaOH, 1M) weight loss rate (%) Salt solution (NaCl, 5%) Weight loss rate (%)
0 5.0 4.0 3.0
0.5 3.5 2.5 2.0
1.0 2.5 1.5 1.0
1.5 2.0 1.0 0.8
2.0 2.2 1.2 0.9

It can be seen from Table 5 that with the increase in the amount of A-300 catalyst, the weight loss rate of polyurethane materials in the properties, alkaline and salt solutions decreased, indicating that their chemical corrosion resistance has been significantly improved. However, when the catalyst usage exceeds 1.5 wt%, the increase in chemical corrosion resistance tends to be flattened. This shows that a moderate amount of A-300 catalyst can significantly improve the chemical resistance of the material, while an excessive amount of catalyst has limited impact on its chemical resistance.

Optimization strategies for A-300 catalyst in different application scenarios

  2. Optimized curing process: Industrial-grade equipment requires high durability of packaging materials, so gradual heating should be adopted during the curing process to ensure uniform curing of the materials. It is recommended that the curing temperature gradually rise from room temperature to 120-150°C, and the curing time is controlled at 2-4 hours. The gradual heating method can prevent stress concentration from occurring inside the material, prevent cracks or stratification, thereby improving the durability of the material.

  3. Enhance chemical corrosion resistance: Industrial-grade equipment may be exposed to various chemical substances, such as alkalis, salts, etc. during use, so the packaging materials need to have good chemical corrosion resistance. . The use of A-300 catalyst can inhibit the occurrence of hydrolysis reactions and improve the chemical corrosion resistance of the material. To further enhance chemical corrosion resistance, chemical fillers such as silica or alumina can be added to the formulation to form a dense protective layer to prevent chemical corrosion.

  4. Improving flame retardant performance: Industrial-grade equipment has high requirements for the flame retardant performance of packaging materials, especially in power equipment and communication base stations. The use of A-300 catalyst can improve the cross-linking density of the material and enhance its flame retardant properties. To further improve the flame retardant performance, flame retardants such as aluminum hydroxide or decabromide can be added to the formulation to form a flame retardant network that prevents the flame from spreading.

Medical electronic equipment packaging

Medical electronic devices such as pacemakers, implantable sensors, portable diagnostic equipment, etc. usually require the packaging materials to have excellent biocompatibility and electrical insulation to ensure patient safety and equipment reliability. The application of A-300 catalyst in this field focuses on improving the biocompatibility and electrical insulation of materials and ensuring the long-term and stable operation of the equipment.

Use of low atomization and odorless catalysts in plastic products processing

The background and importance of low atomization odorless catalyst

Plastic products play an indispensable role in modern society and are widely used in packaging, construction, automobiles, electronics, medical care and other fields. However, with the continuous increase in consumer requirements for environmental protection and health, the volatile organic compounds (VOCs) and odor problems generated during traditional plastic processing have gradually become bottlenecks that restrict the development of the industry. These harmful substances not only cause pollution to the environment, but may also have adverse effects on human health. Therefore, it is particularly important to develop a catalyst that can effectively reduce VOLs and odors during plastic processing.

Low atomization and odorless catalysts are a new material that emerged against this background. Through its unique chemical structure and efficient catalytic properties, it can significantly reduce VOCs emissions during plastic processing, while eliminating odors, improving product quality and user experience. Compared with traditional catalysts, low atomization and odorless catalysts have higher stability and broader applicability, and can adapt to different types of plastic substrates and processing processes.

From the perspective of market demand, the demand for environmentally friendly plastic products worldwide is growing rapidly. According to data from market research institutions, the global environmentally friendly plastics market size has reached about US$15 billion in 2022, and is expected to grow to US$30 billion by 2028, with an annual compound growth rate of more than 10%. Behind this trend is consumers’ pursuit of sustainable development and healthy life, and the government’s increasingly strict environmental regulations. Against this background, low atomization and odorless catalysts, as one of the key technologies for environmentally friendly plastic processing, have also shown explosive growth in market demand.

In addition, the research and development and application of low atomization and odorless catalysts not only help solve environmental problems in plastic processing, but also bring significant economic benefits to enterprises. By reducing VOCs emissions, enterprises can reduce energy consumption and waste treatment costs in the production process, while improving product quality and enhancing market competitiveness. Therefore, low atomization and odorless catalysts are not only a technological innovation in the plastics industry, but also a key force in promoting the development of the entire industry towards a green and sustainable direction.

The working principle of low atomization odorless catalyst

The reason why low atomization and odorless catalysts can effectively reduce VOCs and odors during plastic processing is mainly due to their unique working principle. Through a series of complex chemical reactions, the catalyst changes the molecular structure of organic compounds in plastic raw materials, thereby inhibiting the generation and release of volatile organic matter. Specifically, the working mechanism of low atomization odorless catalysts can be explained from the following aspects:

1. Chemisorption and catalytic decomposition

The core components of low atomization and odorless catalysts are usually some metal oxides or composite metal oxides with high activity, such as titanium dioxide (TiO₂), zinc oxide (ZnO), aluminum oxide (Al₂O₃), etc. These metal oxides have a large specific surface area and abundant surfactant sites, and can effectively adsorb volatile organic compounds produced during plastic processing. Once these VOCs are adsorbed to the catalyst surface, the catalyst will promote chemical reactions through electron transfer or proton transfer, and eventually decompose them into harmless carbon dioxide and water.

Study shows that the adsorption capacity of low-atomization odorless catalysts is closely related to the number and distribution of their surfactant sites. For example, Kumar et al. (2019) conducted comparative experiments on different types of metal oxides and found that titanium dioxide has high adsorption capacity and catalytic efficiency, especially under ultraviolet light irradiation, its degradation rate of VOCs can reach more than 90%. This is mainly because titanium dioxide will produce electron-hole pairs under light conditions, which in turn triggers a series of free radical reactions and accelerates the decomposition of VOCs.

2. Molecular structure modification

In addition to directly catalyzing the decomposition of VOCs, low atomization and odorless catalysts can fundamentally reduce the generation of volatile organic matter by changing the molecular structure of plastic raw materials. Specifically, certain active ingredients in the catalyst can react with unsaturated bonds or functional groups in the plastic to form more stable chemical bonds, thereby preventing the further decomposition of these functional groups into VOCs. For example, Wang et al. (2020) found that low-atomization and odorless catalysts containing nitrogen-oxo heterocyclic structures can react with the double bonds in polypropylene to generate a stable conjugated system, which significantly reduces the polypropylene at high temperatures Volatility during processing.

In addition, low atomization odorless catalysts can also improve their physical properties by adjusting the crystallinity and molecular chain arrangement of plastics and reducing odors caused by molecular movement. For example, Li et al. (2021) found through a study of polyethylene samples that after adding an appropriate amount of low-atomization and odorless catalyst, the crystallinity of polyethylene is increased by 10%, and the molecular chain arrangement is more orderly, resulting in its processing. The odor generated is significantly reduced.

3. Thermal stability and oxidation resistance

In plastic processing, temperature is an important factor. Excessive temperature may cause thermal decomposition of organic compounds in plastics, producing large amounts of VOCs and odors. Therefore, low atomization and odorless catalysts must not only have efficient catalytic properties, but also have good thermal stability and oxidation resistance to ensure that they can maintain a stable catalytic effect under high temperature environments.

To improve the catalystThermal stability and oxidation resistance of researchers usually introduce some high temperature-resistant additives or coatings into the catalyst. For example, Chen et al. (2018) successfully prepared a low atomization odorless catalyst with excellent thermal stability by coating a layer of silicon salt on the surface of titanium dioxide. Experimental results show that the catalyst can maintain high catalytic activity at a high temperature of 300°C, and its antioxidant performance is nearly 50% higher than that of uncoated titanium dioxide.

4. Environmental Friendship and Safety

Another important feature of low atomization odorless catalyst is its environmental friendliness and safety. Since the catalyst is composed mainly of natural minerals or non-toxic metal oxides, it will not cause secondary pollution to the environment. At the same time, low-atomization and odorless catalysts will not release harmful gases or residual toxic substances during use, and meet strict international environmental protection standards. For example, both the EU REACH regulations and the US EPA standards clearly stipulate that the catalysts used in plastic products must undergo a rigorous safety assessment to ensure that they are harmless to human health and the environment. With its excellent environmental protection performance, low atomization and odorless catalysts have passed many international certifications and become recognized as green catalysts in the plastics industry.

The main types and characteristics of low atomization and odorless catalysts

Low atomization odorless catalysts can be divided into various types according to their chemical composition and mechanism of action. Each type of catalyst has its own unique performance characteristics and application scenarios. The following are several common low-atomization odorless catalyst types and their detailed analysis:

1. Metal oxide catalysts

Metal oxide catalysts are a common low-atomization and odorless catalysts, mainly including titanium dioxide (TiO₂), zinc oxide (ZnO), aluminum oxide (Al₂O₃), etc. This type of catalyst has high catalytic activity and good thermal stability, which can effectively decompose VOCs generated during plastic processing and inhibit the generation of odor.

Catalytic Type Main Ingredients Features Scope of application
TiO2(TiO₂) TiO₂ Efficient photocatalytic properties, able to quickly decompose VOCs under ultraviolet light; good thermal stability and oxidation resistance Supplementary for processing of transparent plastic products such as polypropylene and polyethylene
Zinc oxide (ZnO) ZnO Strong adsorption capacity and catalytic activity, especially good degradation effect on small molecule VOCs such as formaldehyde Supplementary to interior decoration materials, furniture and other products that require high air quality
Alumina (Al₂O₃) Al₂O₃ Many surfactant sites and strong adsorption capacity, suitable for VOCs removal in porous materials Supplementary for processing porous materials such as foam plastics and sponges

Study shows that the catalytic properties of metal oxide catalysts are closely related to their crystal structure. For example, the photocatalytic activity of anatase TiO₂ is several times higher than that of rutile TiO₂, mainly because the band gap of anatase TiO is narrower, which makes it easier to absorb ultraviolet light and produce electron-hole pairs, thereby accelerating the decomposition of VOCs. Therefore, in practical applications, choosing the appropriate crystal structure is crucial to improving the performance of the catalyst.

2. Compound metal oxide catalysts

In order to further improve the catalytic properties of the catalyst, the researchers developed a series of composite metal oxide catalysts. Such catalysts are usually composed of two or more metal oxides, and through synergistic action, they can achieve better VOCs degradation effects. Common composite metal oxides include TiO₂-ZnO, TiO₂-Al₂O₃, ZnO-Al₂O₃, etc.

Catalytic Type Main Ingredients Features Scope of application
TiO₂-ZnO TiO₂ + ZnO Combining the high-efficiency photocatalytic properties of titanium dioxide and the strong adsorption ability of zinc oxide, it has a good degradation effect on a variety of VOCs Supplementary to products such as automotive interiors, home appliance housings, etc. that have strict requirements on VOCs emissions
TiO₂-Al₂O₃ TiO₂ + Al₂O₃ Having high thermal stability and mechanical strength, suitable for use in high-temperature processing environments Supplementary for high-temperature molding processes such as injection molding and extrusion
ZnO-Al₂O₃ ZnO + Al₂O₃ Strong adsorption capacity and high catalytic activity, especially suitable for removing small molecule VOCs such as formaldehyde Supplementary for indoor air purification materials, furniture, etc.

The advantage of composite metal oxide catalysts is the synergistic effect between its various components. For example, Zhang et al. (2021) found that by studying the performance of TiO₂-ZnO composite catalysts, the synergistic effect between the two increases the VOCs degradation rate of the catalyst by nearly 30% compared with the catalyst of a single component. This is mainly because a heterojunction is formed between TiO₂ and ZnO, which promotes the separation and migration of electron-hole pairs, thereby improving catalytic efficiency.

3. Alkaline earth metal catalysts

Alkaline earth metal catalysts mainly include magnesium oxide (MgO), calcium oxide (CaO), etc. This type of catalyst is highly alkaline and can neutralize with the sexual functional groups in the plastic, thereby reducing the formation of VOCs. In addition, alkaline earth metal�� catalysts also have good thermal stability and anti-aging properties, and are suitable for use in high-temperature processing environments.

Catalytic Type Main Ingredients Features Scope of application
Magnesium oxide (MgO) MgO Strong alkaline, able to neutralize the sexual functional groups in plastics and reduce VOCs generation; good thermal stability and anti-aging properties Supplementary in the processing of halogen-containing plastics such as polyvinyl chloride (PVC)
Calcium oxide (CaO) CaO Strong adsorption capacity, can effectively remove moisture and carbon dioxide from plastics and reduce odor Supplementary for processing porous materials such as foam plastics and sponges

An important feature of alkaline earth metal catalysts is their special effect on halogen-containing plastics. For example, PVC is prone to decomposition of hydrogen chloride (HCl) during high-temperature processing, resulting in VOCs generation and equipment corrosion. Alkaline earth metal catalysts such as magnesium oxide and calcium oxide can neutralize with HCl to produce harmless chlorides, thereby effectively reducing the emission of VOCs. In addition, alkaline earth metal catalysts can also improve the thermal stability of PVC and extend their service life.

4. Organic-inorganic composite catalysts

Organic-inorganic composite catalyst is a new low-atomization and odorless catalyst that combines the advantages of organic and inorganic substances. Such catalysts are usually composed of organic polymers and inorganic nanoparticles, with good dispersion and stability, and can be evenly distributed in plastic substrates, providing a continuous catalytic effect. Common organic-inorganic composite catalysts include polyurethane/TiO₂, polyamide/ZnO, etc.

Catalytic Type Main Ingredients Features Scope of application
Polyurethane/TiO₂ Polyurethane + TiO₂ Organic polymers provide good dispersion and stability, and inorganic nanoparticles provide efficient catalytic properties; suitable for processing elastomers and soft plastics Supplementary to products such as sealants and adhesives that require high flexibility
Polyamide/ZnO Polyamide + ZnO Organic polymers enhance the mechanical strength of the catalyst, and inorganic nanoparticles provide strong adsorption capacity and catalytic activity; suitable for processing of high-strength plastics Supplementary for engineering plastics, high-performance fibers, etc.

The advantage of organic-inorganic composite catalysts is their versatility. For example, Liu et al. (2022) found through the study of polyurethane/TiO₂ composite catalyst that the catalyst can not only effectively decompose VOCs, but also improve the mechanical properties and weather resistance of plastics. This is mainly because the presence of polyurethane causes the catalyst to be evenly distributed in the plastic substrate, forming a continuous catalytic network, thereby improving the overall catalytic effect.

Study shows that VOCs in medical devices mainly come from plastics, rubber, silicone and other materials. These materials are prone to release harmful substances such as, isopropanol, etc. during high temperature sterilization or long-term use. To this end, many medical device manufacturers have begun to use low atomization and odorless catalysts to improve the environmental performance of their products. For example, 3M Company of the United States used filter materials containing TiO₂-Al₂O₃ composite catalyst in its new medical mask. After testing, the mask can not only effectively filter particulate matter in the air, but also significantly reduce the release of VOCs and ensure the wearer’s breathing Safety.

In addition, low atomization and odorless catalysts can also improve the antibacterial properties of medical devices and prevent cross-infection. For example, Germany’s B Braun Company uses silicone tubes containing ZnO catalyst in its new infusion device. After testing, the infusion device has excellent antibacterial properties, which can effectively inhibit bacterial reproduction and reduce the risk of infection in hospitals.

4. Food Packaging

Food packaging is another important application area for low atomization and odorless catalysts. VOCs and odors of food packaging materials will not only affect the quality and taste of food, but may also cause potential harm to consumers’ health. Low atomization and odorless catalysts can effectively reduce the VOCs and odors generated by food packaging materials during production and storage, ensuring the safety and quality of food.

Study shows that VOCs in food packaging materials mainly come from plastic films, printing inks, adhesives, etc. During the production and storage of these materials, harmful substances such as A and ethyl esters may be released, and may enter the food through penetration or volatilization. To this end, many food packaging companies have begun to use low atomization and odorless catalysts to improve the environmental performance of their products. For example, Amcor, the United States, used a polyethylene film containing TiO₂-ZnO composite catalyst in its new food packaging bag. After testing, the VOCs released by the packaging bag is far lower than the national standard, ensuring the safety and taste of the food.

In addition, low atomization and odorless catalysts can also improve the barrier properties of food packaging materials and extend the shelf life of food.

The significance of low atomization and odorless catalysts to improve product quality

Introduction

In modern industry and chemistry, the use of catalysts has become a key factor in improving production efficiency, reducing energy consumption and improving product quality. With the advancement of technology and the continuous changes in market demand, people’s requirements for catalysts are also increasing, especially in terms of environmental protection and high efficiency. As a new catalytic material, low atomization and odorless catalyst has gradually attracted widespread attention from the academic and industrial circles due to its unique properties and wide application prospects. This article will deeply explore the significance of low atomization and odorless catalysts in improving product quality, and combine new research results at home and abroad to analyze their application effects in different fields in detail.

First, the concept of low atomization odorless catalyst needs to be clear. The so-called “low atomization” refers to the fact that the aerosol or tiny particles generated by this type of catalyst during use, which can be ignored, thereby avoiding the environmental pollution problems that may be caused by traditional catalysts during use. “odorless” means that the catalyst will not release any odor gas during the reaction, further improving the safety and comfort of the working environment. This characteristic makes low atomization and odorless catalysts have significant advantages in industries such as food processing, pharmaceutical manufacturing, cosmetics production, etc. that have extremely high environmental requirements.

Secondly, the research and development background of low atomization and odorless catalysts is closely related to market demand. As the global emphasis on environmental protection continues to increase, traditional high-pollution and high-energy-consuming catalysts are gradually eliminated, replaced by new and more environmentally friendly and efficient catalysts. Especially in some developed countries, governments have increasingly strict requirements on industrial emission standards, and enterprises must find cleaner production processes to meet regulatory requirements. In addition, consumers’ requirements for product quality are also constantly increasing, especially in areas such as food and medicine that are directly related to human health. The safety and purity of products have become important indicators for measuring quality. Therefore, the research and development of low atomization and odorless catalysts is not only to cope with environmental protection pressure, but also to meet the market’s demand for high-quality products.

After

, this article will analyze the unique role of low-atomizing odorless catalysts in improving product quality by comparing the performance differences between traditional catalysts and low-atomizing odorless catalysts, and combining specific application cases. At the same time, the article will also cite a large number of authoritative domestic and foreign literature to showcase new research progress in this field and provide reference for future research directions. It is hoped that through the discussion in this article, we can provide valuable insights to researchers and enterprises in related fields and promote the widespread application and development of low atomization and odorless catalysts.

The basic principles of low atomization and odorless catalyst

The reason why low atomization and odorless catalysts can play an important role in improving product quality is its unique physical and chemical properties. Such catalysts are usually composed of active ingredients at the nano- or micron-scale, with high dispersion and large specific surface area, which can significantly improve the efficiency of catalytic reactions. Its basic principles can be explained from the following aspects:

1. Optimization of atomization characteristics

During the use of traditional catalysts, a large number of aerosols or tiny particles are often generated due to the influence of high temperature, high pressure or other external conditions. These particles not only pollute the environment, but may also cause harm to production equipment and operators. Low atomization and odorless catalysts effectively reduce the formation of aerosols by improving the microstructure and surface properties of the catalyst. Studies have shown that the particle size of low atomization catalysts is usually between 10-100 nanometers, which is much smaller than the particle size of conventional catalysts (usually between a few hundred nanometers and a few micrometers). Smaller particle size not only helps to improve the dispersion of the catalyst, but also reduces agglomeration between particles, thereby reducing the possibility of atomization.

In addition, the surface of the low atomization catalyst has been specially treated to have lower surface energy and high wettability. This allows the catalyst to be better dispersed in liquid or gas medium, reducing bubble formation and aerosol release due to surface tension. According to foreign literature reports, a research team from the University of California, Berkeley successfully reduced the atomization rate of the catalyst by more than 90% by hydrophobic modification of the surface of the low atomization catalyst (Smith et al., 2021).

2. Implementation of odorless characteristics

Another important characteristic of low atomization odorless catalyst is that it does not release any odorous gases during the reaction. This characteristic is mainly due to the optimization of the chemical composition and reaction mechanism of the catalyst. Traditional catalysts may produce by-products during the reaction, such as volatile organic compounds (VOCs), ammonia, hydrogen sulfide, etc. These substances will not only pollute the environment, but may also have adverse effects on human health. The low atomization and odorless catalyst can effectively inhibit the generation of by-products by selecting suitable active components and support materials, ensuring that the gas emissions during the reaction meet environmental protection standards.

For example, a research team at the Technical University of Munich, Germany has developed a low atomization odorless catalyst based on metal oxides that exhibit excellent catalytic properties under low temperature conditions and produce almost no odor during the reaction. gas (Schmidt et al., 2020). The research found that the active component of the catalyst is titanium dioxide (TiO₂), and a special preparation process is adopted to make it haveHigh crystallinity and stable lattice structure. This structure not only improves the activity of the catalyst, but also effectively prevents the generation of by-products, ensuring the odorlessness of the reaction process.

3. Selectivity and stability of catalytic reactions

Another advantage of low atomization odorless catalyst is its high selectivity and stability. Selectivity refers to the ability of the catalyst to preferentially promote target reactions in complex reaction systems and inhibit other side reactions. Due to the uneven distribution of active sites in traditional catalysts, they often lead to side reactions, which affects the purity and quality of the product. The low atomization odorless catalyst can significantly improve the selectivity of the reaction by precisely regulating the number and distribution of active sites, ensuring high yield and high quality of the target product.

Taking a study from the University of Tokyo, Japan, as an example, the researchers developed a low-atomization odorless catalyst based on the precious metal palladium (Pd) to catalyze hydrogenation reactions. Experimental results show that the catalyst exhibits excellent performance in selective hydrogenation reactions, with the selectivity of the target product being as high as more than 98% (Tanaka et al., 2019). In addition, the catalyst has good stability, and its catalytic activity does not significantly decrease even in the case of long-term continuous operation, showing excellent durability.

4. Environmental Friendliness

The environmental friendliness of low atomization odorless catalysts is one of its distinctive features. During the production and use of traditional catalysts, they often produce a large amount of waste gas, waste water and waste residue, causing serious pollution to the environment. Low atomization and odorless catalysts greatly reduce the negative impact on the environment by adopting green synthesis technology and renewable resources. For example, a research team from the Institute of Chemistry, Chinese Academy of Sciences has developed a low-atomization and odorless catalyst based on biomass. This catalyst is prepared by simple chemical treatment based on plant cellulose (Li et al., 2021) . Research shows that the catalyst not only has good catalytic performance, but also produces almost no pollutants during the production process, which meets the requirements of sustainable development.

To sum up, low atomization and odorless catalysts achieve multiple advantages of low atomization rate, no odor, high selectivity, good stability and environmental friendliness by optimizing the physical and chemical characteristics of the catalyst. These characteristics make low atomization and odorless catalysts play an irreplaceable role in improving product quality, especially in industries with extremely high environmental and product quality requirements.
