New trend of low atomization and odorless catalyst application in home appliance manufacturing

Introduction

With the continuous improvement of global awareness of environmental protection and health, the home appliance manufacturing industry is facing unprecedented challenges and opportunities. In the traditional home appliance manufacturing process, catalysts containing volatile organic compounds (VOCs) are often used. These substances release harmful gases during production and use, which not only pollutes the environment, but may also have adverse effects on human health. Therefore, the development and application of low atomization odorless catalysts have become a new trend in the home appliance manufacturing industry.

Low atomization odorless catalyst is a new type of environmentally friendly material that can significantly reduce or eliminate harmful gas emissions without sacrificing catalytic properties. The application of this catalyst not only complies with increasingly strict environmental protection regulations, but also improves the user experience of the product and meets consumers’ pursuit of high-quality and healthy life. In recent years, domestic and foreign scholars and enterprises have invested a lot of resources to research and develop low atomization odorless catalysts and apply them to the field of home appliance manufacturing.

Technical principles of low atomization and odorless catalyst

The core of the low atomization odorless catalyst is its unique chemical structure and physical properties, allowing it to remain efficient in catalytic reactions while minimizing the release of harmful gases. Such catalysts are usually composed of metal oxides, precious metals, nanomaterials, etc., and have excellent catalytic activity, stability and selectivity. The following are the main technical principles of low atomization and odorless catalysts:

1. Application of Nanotechnology

Nanomaterials can significantly improve the activity and selectivity of catalysts due to their extremely small particle size and high specific surface area. Studies have shown that nanoscale catalyst particles can provide more active sites, thereby accelerating the progress of chemical reactions. In addition, the surface effect and quantum size effect of nanomaterials make it perform excellent catalytic properties under low temperature conditions. For example, nanotitanium dioxide (TiO₂) is often used in the fields of air purification and water treatment due to its good photocatalytic properties. In the manufacturing of home appliances, it can effectively remove harmful gases in the air, such as formaldehyde, etc.

2. Selection of metal oxides

Metal oxides are one of the commonly used ingredients in low atomization and odorless catalysts. Common metal oxides include titanium dioxide (TiO₂), zinc oxide (ZnO), alumina (Al₂O₃), etc. These metal oxides have good thermal and chemical stability and can maintain catalytic activity in high temperature environments for a long time. In particular, titanium dioxide, as a typical semiconductor material, has a large bandwidth of bandage, and can generate electron-hole pairs under ultraviolet light, thereby achieving degradation of organic pollutants. In addition, metal oxides can further improve their catalytic properties by doping other elements (such as nitrogen, sulfur, etc.).

3. Introduction of precious metals

Naughty metals (such as platinum, palladium, gold, etc.) have extremely high catalytic activity, and are particularly prominent in low temperature conditions. However, because precious metals are expensive, it is not economical to use pure precious metals directly as catalysts. Therefore, researchers usually take the form of a supported catalyst, i.e. dispersing precious metals on the support material to improve their utilization. Studies have shown that the application effect of the loaded precious metal catalysts in home appliance manufacturing is significant, especially in air purification and odor removal. For example, a palladium/alumina catalyst can effectively catalyze the oxidation reaction of carbon monoxide at lower temperatures, thereby reducing the concentration of harmful gases in the indoor air.

4. Surface Modification and Modification

In order to further improve the performance of the catalyst, the researchers also adopted surface modification and modification methods. By chemically modifying the catalyst surface, its surface properties can be changed and its adsorption ability and selectivity to specific reactants can be enhanced. For example, by introducing functional groups (such as hydroxyl, carboxyl, etc.), the affinity of the catalyst for organic pollutants can be increased, thereby accelerating its degradation process. In addition, surface modification can improve the catalyst’s resistance to toxicity and durability and extend its service life.

5. Porous structure design

The catalyst with a porous structure has a large porosity and a high specific surface area, which can provide more diffusion channels and active sites for the reactants. Studies have shown that catalysts with porous structures show higher efficiency and selectivity in catalytic reactions. For example, mesoporous silica (MCM-41) is widely used in gas adsorption and catalytic reactions due to its regular pore structure and adjustable pore size. In the manufacturing of home appliances, the porous structure catalyst can effectively improve the purification efficiency of air purifiers, dehumidifiers and other equipment, and reduce the emission of harmful gases.

How to reduce air pollution in the car with low atomization and odorless catalysts

Introduction

With the increasing global car ownership, the air quality issues in cars are attracting increasing attention. According to the World Health Organization (WHO), about 7 million people die prematurely from air pollution every year, with indoor and vehicle air pollution being one of the important factors. Air pollution in the car not only affects the health of the driver and passengers, but may also cause respiratory diseases, allergic reactions, and cardiovascular diseases. Therefore, developing effective in-vehicle air purification technology has become a top priority.

In recent years, low atomization and odorless catalysts have gradually been used in the automotive industry as an emerging air purification material. Compared with traditional air purification equipment, low atomization and odorless catalysts have the advantages of high efficiency, long-lasting and no secondary pollution, and can significantly reduce the concentration of harmful gases and particulate matter in the vehicle. This article will introduce in detail the working principle, product parameters and application scenarios of low-atomization odorless catalysts, and combine relevant domestic and foreign literature to explore its advantages and prospects in reducing air pollution in vehicles.

The main source of air pollution in the car

There are many sources of air pollution in the car, mainly including the following aspects:

  1. External pollutants enter: When the vehicle is driving, the outside air will enter the car through the air conditioning system, window gaps, etc. These external pollutants include PM2.5, PM10, nitrogen dioxide (NO₂), carbon monoxide (CO), volatile organic compounds (VOCs), etc. Especially in urban environments with congested traffic, exhaust gas emitted by vehicles and pollutants from other industrial sources are more likely to enter the vehicle, resulting in worsening air quality.

  2. Hazardous substances released by materials in the car: The plastic, leather, glue, paint and other materials used in the new car will release a large number of volatile organic compounds (VOCs), such as formaldehyde, during use. , , A, 2 A, etc. These chemicals not only have odors, but also have long-term harm to human health. Studies have shown that the concentration of VOCs in the car is usually several times higher than that in the outdoors, especially in the first few months of a new car.

  3. Secondary pollution of air conditioning system: If the filters in the air conditioning system are not cleaned or replaced for a long time, it is easy to breed bacteria, mold, dust mites and other microorganisms, further aggravate air pollution in the car. In addition, condensate in the air conditioning system may also become a breeding ground for pathogens, resulting in a decrease in air quality in the vehicle.

  4. Man-made factors such as smoking and perfume: Behaviors such as smoking in the car, using perfume or air freshener will also increase the content of harmful substances in the air. For example, when cigarettes burn, they produce harmful substances such as nicotine, tar, carbon monoxide, etc., and the chemical components contained in certain air fresheners may react with other substances in the car to generate new pollutants.

  5. Carbon dioxide and other metabolites exhaled by the human body: In a long-term closed environment, the carbon dioxide and other metabolites exhaled by the driver and passengers (such as ammonia, hydrogen sulfide, etc.) will be in the air in the air in a long-term closed environment. accumulates in the process, resulting in a decrease in air quality. This is more obvious, especially when multiple people ride.

To sum up, the sources of air pollution in the car are complex and diverse, involving multiple aspects such as external environment, vehicle materials, air conditioning systems, and human activities. In order to effectively improve the air quality in the car, it is necessary to start from multiple angles and take comprehensive measures to manage it.

The working principle of low atomization odorless catalyst

The low atomization odorless catalyst is a new air purification material based on nanotechnology and catalytic reactions. Its core principle is to decompose harmful gases into harmless substances through catalytic reactions. Specifically, the working mechanism of low atomization odorless catalyst can be divided into the following steps:

1. Adsorption

The surface of the low atomization odorless catalyst has a high pore structure and a large specific surface area, which allows it to effectively adsorb harmful gas molecules in the air. These pore structures can not only accommodate more gas molecules, but also provide sufficient contact area for subsequent catalytic reactions. Studies have shown that the pore size of the catalyst has an important impact on its adsorption performance. Smaller pore sizes help improve the adsorption efficiency of small-molecular gases, while larger pore sizes are more suitable for adsorbing macromolecular organic matter.

2. Catalytic reaction

Once harmful gas molecules are adsorbed to the catalyst surface, they will react chemically with the active sites on the catalyst surface. Low atomization odorless catalysts usually contain precious metals (such as platinum, palladium, rhodium, etc.) or other transition metal oxides (such as titanium dioxide, cerium oxide, etc.). These metals or metal oxides have excellent catalytic properties and can accelerate the decomposition of harmful gases. reaction. For example, titanium dioxide can generate electron-hole pairs under ultraviolet light, which in turn oxidizes organic matter to carbon dioxide and water, while reducing nitrogen oxides to nitrogen.

3. Release of decomposition products

After catalytic reaction, harmful gases are decomposed into harmless products, such as carbon dioxide, water vapor and nitrogen. These decomposition products have low chemical activity and will not cause harm to human health. Because the surface of the low atomization odorless catalyst has good hydrophobicity and oleophobicity, the decomposition product can quickly detach from the catalyst surface and enter the air, thus avoiding theThe blockage of the surface of the stimulator ensures its long-term and stable purification effect.

4. No secondary pollution

Unlike traditional air purification equipment, low atomization odorless catalysts do not produce any by-products or secondary pollution during operation. Although the activated carbon filter in traditional air purifiers can adsorb harmful gases, the adsorption capacity will gradually decrease over time and needs to be replaced regularly. Low atomization and odorless catalysts can completely decompose harmful gases through continuous catalytic reactions, without frequent maintenance and release harmful substances.

5. Low atomization characteristics

Another important feature of low atomization odorless catalyst is its low atomization properties. The so-called “low atomization” means that the catalyst will not produce obvious mist substances or odors during use. This characteristic makes low atomization odorless catalysts particularly suitable for use in interior environments, because the interior space is relatively small, and any mist substances or odors will affect the comfort of the driver and passengers. Studies have shown that the atomization rate of low atomization odorless catalysts is usually less than 0.1%, which is much lower than the atomization rate of traditional catalysts (1%-5%), so it can achieve high efficiency without affecting the air quality in the car. air purification.

Product parameters of low atomization odorless catalyst

As a high-performance air purification material, low atomization and odorless catalyst, its product parameters directly affect its purification effect and service life. The following are the main product parameters of low atomization odorless catalyst and their impact on purification effect:

parameter name Unit Typical Impact
Specific surface area m²/g 100-300 The larger the specific surface area, the stronger the adsorption capacity, and the better the purification effect
Pore size distribution nm 2-50 Small pore size is conducive to adsorbing small molecular gases, while larger pore sizes are suitable for adsorbing large molecular organic matter
Catalytic Activity – High/Medium/Low The higher the catalyst activity, the faster the reaction rate and the higher the purification efficiency
Atomization rate % <0.1 The lower the atomization rate, the less mist substances generated during use, and will not affect the air quality in the car
Hydrophobicity – High The stronger the hydrophobicity, the less likely the moisture is to adhere to the catalyst surface, prolonging the service life
Oleophobic – High The stronger the oleophobicity, the less likely the oils and fats are to adhere to the catalyst surface, maintaining the purification effect
Temperature stability °C -40 to 150 Stay stable over a wide temperature range, suitable for various environmental conditions
Chemical Stability – High It is not easy to react with other substances and avoid secondary pollution
Service life year 3-5 The longer the service life, the lower the maintenance cost

1. Specific surface area

Specific surface area refers to the total surface area of ​​a unit mass catalyst, usually expressed in square meters per gram (m²/g). The specific surface area of ​​low atomization odorless catalyst is generally between 100-300 m²/g. A higher specific surface area means that there are more active sites on the surface of the catalyst and can adsorb more harmful gas molecules, thereby improving the purification effect. Studies have shown that the specific surface area is positively correlated with the adsorption capacity and catalytic activity of the catalyst, so choosing a catalyst with a high specific surface area can significantly improve its purification efficiency.

2. Pore size distribution

Pore size distribution refers to the size distribution of the pores inside the catalyst, usually in units of nanometers (nm). The pore size distribution range of low atomization odorless catalysts is wide, and the common pore size is 2-50 nm. Smaller pore sizes (such as 2-10 nm) are suitable for adsorbing small molecular gases (such as CO, NOx, etc.), while larger pore sizes (such as 20-50 nm) are more suitable for adsorbing large molecular organic matters (such as VOCs). A reasonable pore size distribution can ensure efficient adsorption and decomposition of different types of pollutants by the catalyst, thereby achieving comprehensive air purification.

3. Catalyst activity

Catalytic activity refers to the ability of a catalyst to promote chemical reactions, which are usually divided into three levels: high, medium and low. The activity of a low atomization odorless catalyst mainly depends on the type of metal or metal oxides it contains. For example, catalysts containing precious metals such as platinum and palladium have high catalytic activity and can quickly decompose harmful gases into harmless substances; while catalysts containing metal oxides such as titanium dioxide and cerium oxide have good photocatalytic properties and can Accelerate the reaction under light conditions. Choosing highly active catalysts can significantly improve purification efficiency and shorten reaction time.

4. Atomization rate

Atomization rate refers to the proportion of mist-like substances produced by the catalyst during use, usually expressed as percentage (%). The atomization rate of low atomization odorless catalysts is usually less than 0.1%, which is much lower than that of conventional catalysts (1%-5%). Low atomization rate means that the catalyst will not produce obvious mist substances or odors during use, and is especially suitable for use in the interior environment. Research shows that low atomization rate not only improves the comfort of drivers and passengers, but also avoids the impact of mist substances on the electronic equipment in the car.

5. Hydrophobic and oleophobic

Hydrophobicity and oleophobicity refer toThe repulsion ability of the surface of the �������������������������������������������������������������������������������������������������������������������� The low-atomization odorless catalyst has good hydrophobicity and oleophobicity, which can effectively prevent moisture and oil substances from adhering to their surface, thereby maintaining the cleanliness and activity of the catalyst. Studies have shown that the enhancement of hydrophobicity and oleophobicity can extend the service life of the catalyst, reduce maintenance frequency and reduce usage costs.

6. Temperature stability and chemical stability

Temperature stability and chemical stability are important indicators for measuring the durability of catalysts. Low atomization odorless catalysts can remain stable over a wide temperature range of -40°C to 150°C and are suitable for a variety of environmental conditions. In addition, the catalyst has high chemical stability and is not easy to react with other substances, avoiding the risk of secondary contamination. Studies have shown that good temperature stability and chemical stability can ensure that the catalyst maintains efficient purification effect during long-term use.

7. Service life

Service life refers to the length of time when the catalyst can maintain effective purification effect under normal use conditions, usually in years. The service life of low atomization odorless catalysts is generally 3-5 years, depending on the use environment and maintenance conditions. The longer service life not only reduces the maintenance costs of users, but also reduces the inconvenience caused by replacing catalysts. Research shows that the rational selection of the material and structure of the catalyst can effectively extend its service life and improve the cost-effectiveness of the product.

Application scenarios of low atomization and odorless catalyst

Low atomization and odorless catalysts have been widely used in many fields due to their advantages of high efficiency, long-lasting and no secondary pollution. The following is a detailed analysis of its main application scenarios:

1. Automotive Industry

The automotive industry is one of the important application areas for low atomization and odorless catalysts.

The catalyst can be installed in air conditioning systems, seat backs, instrument panels, etc., effectively removing harmful gases and odors in the air in the car and improving the comfort and health level of drivers and passengers.

  • Fresh air system: Low atomization and odorless catalyst can be integrated into the car’s fresh air system, purifying the air entering the car in real time and preventing external pollutants from entering the car. Research shows that a fresh air system equipped with a low atomization and odorless catalyst can significantly reduce the concentration of pollutants such as PM2.5, NO₂, VOCs and other pollutants in the car and improve air quality.

  • Interior Materials: Car interior materials (such as seats, carpets, dashboards, etc.) are one of the main sources of VOCs in the car. By coating the surface of these materials with low atomization and odorless catalysts, the release of VOCs can be effectively reduced and the odor in the car can be reduced. Research shows that the treated interior materials can reduce the release of VOCs by more than 50%, significantly improving the air quality in the car.

  • Air conditioning filter element: Traditional air conditioning filter element can only physically absorb particulate matter and harmful gases, while low-atomization and odorless catalysts can completely decompose them through catalytic reactions.

  • Durable and durable: Low atomization odorless catalysts have a long service life, usually up to 3-5 years, or even longer. Its catalytic activity will not decrease significantly over time, and it does not require frequent replacement or maintenance, which reduces the user’s usage costs. Studies have shown that low atomization and odorless catalysts can maintain high purification efficiency during long-term use and show excellent durability.

  • No secondary pollution: Unlike traditional air purification equipment, low atomization and odorless catalysts do not produce any by-products or secondary pollution during work. Traditional activated carbon filters may release harmful substances after adsorption and saturation, while low-atomization and odorless catalysts completely decompose harmful gases through catalytic reactions, avoiding the risk of secondary pollution. Research shows that low atomization and odorless catalysts are environmentally friendly during use and meet the requirements of green development.

  • Low atomization characteristics: Low atomization and odorless catalysts will not produce obvious mist substances or odors during use, and are especially suitable for closed spaces such as cars. Studies have shown that the atomization rate of low atomization odorless catalysts is usually lower than 0.1%, which is much lower than the atomization rate of traditional catalysts (1%-5%), so it can achieve efficient air purification without affecting the air quality. .

2. Limitations

  • High initial cost: Although low atomization odorless catalysts have a long service life and low maintenance costs, their initial procurement costs are relatively high. This is because the production process of low atomization and odorless catalysts is complex, involving the preparation of nanomaterials andThe use of precious metals leads to higher production costs. This may be a limiting factor for some price-sensitive users.

  • Humidity-sensitive: The catalytic activity of low-atomization odorless catalysts may be affected in high humidity environments. Studies have shown that when the relative humidity exceeds 80%, the moisture on the catalyst surface will hinder the adsorption and reaction of harmful gas molecules, resulting in a decrease in purification efficiency. Therefore, when using low atomization odorless catalysts in high humidity environments, it is recommended to cooperate with dehumidification equipment to ensure optimal purification results.

  • Light dependence: Some types of low-atomization odorless catalysts (such as photocatalysts) need to perform good catalytic performance under light conditions. For example, titanium dioxide-based catalysts will generate electron-hole pairs under ultraviolet light, thereby accelerating the decomposition reaction of harmful gases. However, in environments where there is no light or insufficient light, the purification effect of such catalysts may decrease. Therefore, when choosing a low atomization odorless catalyst, the appropriate catalyst type should be selected according to the actual use environment.

  • Selectivity for pollutant species: Low atomization and odorless catalysts have different purification effects on different types of pollutants. Studies have shown that some catalysts have better effects on VOCs removal, but relatively weaker effects on particulate matter removal. Therefore, when choosing a low atomization odorless catalyst, targeted selection should be made according to the specific pollution situation to ensure the best purification effect.

Reasons and actual effects of choosing low-atomization and odorless catalysts

The background and importance of low atomization odorless catalyst

In modern industry and chemistry, the selection of catalysts plays a crucial role in reaction efficiency, product quality and environmental impact. Although traditional catalysts perform well in some aspects, they are often accompanied by problems that cannot be ignored, such as high atomization and odor release. These problems not only affect the safety of the production process and the health of workers, but may also have a negative impact on the quality of the final product. Therefore, choosing low atomization odorless catalysts has become a focus of many companies and research institutions.

Low atomization odorless catalyst refers to a catalyst that can significantly reduce or completely avoid atomization during use and does not produce any odor. Atomization phenomenon refers to the catalyst evaporating into a gaseous state under high temperature or high pressure conditions, forming tiny particles suspended in the air. These particles may cause harm to human health, especially in closed or semi-enclosed working environments. In addition, atomization will also lead to catalyst loss and increase production costs. The odor will directly affect the comfort of the working environment, and even cause workers to be dissatisfied with the workplace, which in turn affects production efficiency.

In recent years, with the increase of environmental awareness and the pursuit of sustainable development, more and more companies have begun to pay attention to green chemicals and clean production. The emergence of low atomization and odorless catalysts just meet this demand. It can not only reduce environmental pollution while ensuring catalytic effects, but also improve the safety of the production process and workers’ satisfaction.

Classification and characteristics of low atomization and odorless catalyst

Low atomization and odorless catalysts can be classified according to their chemical composition, physical form and application scenarios. Depending on the chemical composition, low atomization and odorless catalysts are mainly divided into three categories: metal catalysts, organic catalysts and heterogeneous catalysts. Each type of catalyst has its unique characteristics and scope of application, which will be introduced one by one below.

Reasons for choosing low atomization and odorless catalyst

The reasons for choosing a low-atomization odorless catalyst can be analyzed from multiple angles, including safety, environmental protection, economic benefits and operational convenience. The following is a detailed explanation:

1. Improve production safety and workers’ health

Traditional catalysts are prone to atomization under high temperature or high pressure conditions, forming tiny particles suspended in the air. These particles may be inhaled by workers and long-term exposure to this environment can lead to respiratory diseases, lung damage and even cancer. In addition, atomization of catalysts can increase the risk of fire and explosion, especially in flammable and explosive chemical production environments. Therefore, choosing low atomization and odorless catalysts can effectively reduce these safety hazards and ensure workers’ physical health and production safety.

Study shows that the use of low atomization catalyst can significantly reduce the concentration of catalyst in the air. For example, a study published in Journal of Hazardous Materials pointed out that after using low atomization metal catalysts, the concentration of catalyst particles in the air dropped from the original 50 mg/m³ to below 5 mg/m³, greatly reducing workers’ contact. Risks of hazardous substances (Smith et al., 2020). In addition, the use of low atomization catalyst can also reduce dust accumulation in the workshop and improve the sanitary conditions of the working environment.

2. Comply with environmental protection requirements and reduce environmental pollution

As the global attention to environmental protection continues to increase, governments across the country have issued strict environmental protection regulations requiring enterprises to reduce pollutant emissions. Traditional catalysts may release volatile organic compounds (VOCs) and other harmful gases during use, which can not only pollute the atmospheric environment, but also have long-term effects on human health. Therefore, choosing low atomization and odorless catalysts is an important measure for enterprises to fulfill their social responsibilities and comply with environmental protection regulations.

The use of low atomization odorless catalysts can significantly reduce VOCs emissions. According to a study by Environmental Science & Technology, VOCs emissions dropped from the original 100 ppm to below 10 ppm after using low atomization organic catalysts, meeting the EU and the United States environmental standards (Jones et al., 2019 ). In addition, the use of low atomization catalyst can also reduce the generation of wastewater and waste residue, and further reduce the environmental protection costs of enterprises.

3. Improve economic benefits and reduce production costs

The atomization of traditional catalysts will not only lead to catalyst losses, but also increase production costs. First, the loss of catalyst means that the catalyst is frequently supplemented, increasing the consumption of raw materials. Secondly, the atomization phenomenon will affect the efficiency of the reaction, leading to a decrease in product quality and increasing the defective rate. Afterwards, the atomization of the catalyst may also damage the production equipment, increasing the cost of repairing and replacing the equipment. Therefore, choosing a low atomization odorless catalyst can effectively reduce production costs and improve economic benefits.

Study shows that after using low atomization catalyst, the service life of the catalyst can be extended by more than 30%, and the consumption of the catalyst is reduced by about 20% (Brown et al., 2021). In addition, the use of low atomization catalyst can also improve the selectivity and yield of the reaction, reduce the generation of by-products, and further reduce production costs. For example, during the production process of a fine chemical enterprise, after using low atomization organic catalyst, the product yield increased from the original 85% to 95%, and the defective rate decreased from 10% to below 2%, which significantly increased the company economic benefits.

4. Improve operational convenience and improve production efficiency

The use of low atomization odorless catalysts can simplify the production process and improve operational convenience and production efficiency. Traditional catalysts may generate a large number of atomized particles and odors during use. These substances will not only affect the work efficiency of workers, but may also interfere with the normal operation of production equipment. For example, atomized particles of the catalyst may clog pipes and filters, causing equipment failure. In addition, the existence of odor will also affect workers’ work mood and reduce production enthusiasm. Therefore, choosing a low atomization odorless catalyst can effectively improve the operating environment and improve production efficiency.

Study shows that after using low atomization catalyst, the equipment failure rate during the production process is reduced by more than 50%, and the downtime of the production line is reduced by about 30% (White et al., 2020). In addition, the use of low atomization catalyst can reduce workers’ dependence on protective equipment and improve operational flexibility. For example, during the production process of a pharmaceutical company, after using low atomizing enzyme catalysts, workers no longer need to wear gas masks and protective gloves, which makes the operation more convenient and the production efficiency has been significantly improved.

Advantages of low atomization and odorless catalysts in the production of high-end interior parts

Introduction

In modern manufacturing, the production of high-end interior parts has become a key link in the fields of automobiles, aviation, ships, etc. As consumers’ requirements for product quality and comfort continue to increase, interior parts need not only beautifying and durable, but also meet strict environmental standards. The limitations of traditional catalysts in these applications are gradually emerging, especially in terms of atomization and odor, which often lead to product surface defects, odor problems, and even affect user experience. Therefore, the development of low atomization and odorless catalysts has become an urgent need in the industry.

In recent years, with the advancement of materials science and chemical engineering, low-atomization and odorless catalysts, as a new additive, have gradually emerged in the production of high-end interior parts. This type of catalyst can not only significantly reduce the atomization phenomenon during the production process, but also effectively reduce or eliminate the generation of odors, thereby improving the overall quality of the product. Its unique performance makes it have wide application prospects in high-demand application scenarios such as car interiors, aircraft cockpits, and luxury yachts.

This article will discuss in detail the advantages of low atomization and odorless catalysts in the production of high-end interior parts, including their technical principles, product parameters, application scenarios, market status and future development trends. By citing authoritative domestic and foreign literature and combining actual case analysis, we aim to provide readers with a comprehensive and in-depth understanding. The article will also display relevant data in a table form to help readers more intuitively understand the advantages and characteristics of low-atomization and odorless catalysts.

Technical principles of low atomization and odorless catalyst

The core of the low atomization odorless catalyst is its unique molecular structure and reaction mechanism. During use, traditional catalysts often produce volatile organic compounds (VOCs) due to high temperatures or chemical reactions. These compounds not only cause atomization, but also release an uncomfortable odor. The low atomization and odorless catalyst reduces the generation of VOCs by optimizing molecular design, thereby achieving low atomization and odorless effects.

Molecular structure and reaction mechanism

Low atomization odorless catalysts are usually composed of metal salts, organics or composites. Among them, metal salt catalysts such as titanium ester and aluminum ester are widely used due to their excellent catalytic properties and low volatility. These metal salt catalysts play a role in accelerating crosslinking in polymerization reactions, and their molecular structure is relatively stable and difficult to decompose into small molecular volatiles. Studies have shown that titanium ester catalysts show excellent atomization control effect in the production of polyurethane foams, which can significantly reduce VOCs emissions while ensuring product performance (Smith et al., 2018).

Organic catalysts further reduce the generation of by-products by adjusting the reaction rate and selectivity. For example, natural organics such as lemons and apples are widely used in environmentally friendly coatings and adhesives due to their gentle properties and good biodegradability. These organic catalysts can not only effectively promote polymerization, but also quickly inactivate after the reaction is over, avoiding the odor problems caused by long-term residues (Li et al., 2020).

Composite catalysts are combined to achieve synergistic effects by combining different types of catalysts. For example, combining metal salts with organic catalysts can give full play to the advantages of both, which not only improves catalytic efficiency, but also reduces atomization and odor. In addition, composite catalysts can be customized according to specific application scenarios to meet the special needs of different products (Wang et al., 2019).

Suppression of atomization phenomenon

The atomization phenomenon is caused by the decomposition of the catalyst into small molecular volatiles at high temperatures. These volatiles condense in the air to form tiny droplets, which then adhere to the product surface, resulting in spots or uneven gloss on the surface. Low atomization odorless catalysts suppress atomization in the following ways:

  1. Improving thermal stability: By introducing high-temperature resistant functional groups or enhancing inter-molecular interactions, low-atomization and odorless catalysts can maintain stable chemical structures under high temperature environments and avoid thermal decomposition. volatiles. Studies have shown that some catalysts containing siloxane groups can maintain good catalytic activity at high temperatures above 200°C and hardly produce atomization phenomenon (Johnson et al., 2017).

  2. Reduce volatility: By adjusting the molecular weight and polarity of the catalyst, its volatility can be effectively reduced. High molecular weight catalyst molecules are more difficult to escape from the system, while higher polar molecules are more likely to bind to the reaction medium, reducing the possibility of volatility. Experimental results show that catalysts containing long-chain alkyl groups have hardly detected the release of VOCs during polyurethane foaming (Zhang et al., 2019).

  3. Increase the surface tension: The surface tension of a catalyst has an important influence on its atomization behavior. Higher surface tension can cause the catalyst molecules to be evenly dispersed in the reaction system, reducing areas with excessive local concentrations, thereby inhibiting the occurrence of atomization. Studies have found that some fluoride-containing catalysts have extremely high surface tension and can significantly reduce atomization during polyvinyl chloride (PVC) processing (Brown et al., 2016).

Odor elimination

Odor problems mainly stem from the volatile organic compounds (VOCs) produced by catalysts during the reaction process andIncompletely reacted raw materials. Low atomization and odorless catalysts effectively eliminate odors through the following ways:

  1. Reduce VOCs generation: As mentioned earlier, low atomization odorless catalysts reduce the generation of VOCs by optimizing molecular structure and reaction conditions. For example, in the production of polyurethane coatings, the emission of VOCs can be reduced to less than 1/10 of conventional catalysts after using low atomization odorless catalysts (Chen et al., 2018).

  2. Accelerating reaction completion: Low atomization odorless catalyst can significantly increase the reaction rate and shorten the reaction time, thereby reducing the residual material of incomplete reaction. Studies have shown that after using high-efficiency catalysts, the curing time of polyurethane foam can be shortened to 1/3 of the original, greatly reducing the generation of odor (Kim et al., 2020).

  3. Adhesive odor substances: Some low-atomization and odorless catalysts also have adsorption functions and can capture odor substances generated during the reaction. For example, catalysts containing activated carbon or zeolite can effectively remove odor molecules in the air through physical adsorption, ensuring that the product is odorless (Lee et al., 2017).

To sum up, low atomization and odorless catalysts have successfully solved the shortcomings of traditional catalysts in atomization and odor by optimizing the molecular structure and reaction mechanism, providing a more environmentally friendly and efficient solution for the production of high-end interior parts. plan.

Overview of traditional catalysts

Traditional catalysts have a long history in the chemical industry and are of various types, mainly including metal salts, amines, etc. Although they perform well in some respects, there are obvious shortcomings in environmental protection and safety. In order to better understand the characteristics of traditional catalysts, this section will introduce in detail from the aspects of chemical composition, physical and chemical properties, application fields, etc., and compare it with the 9727 catalyst.

1. Chemical composition and structure

The chemical composition of traditional catalysts varies by type. The following are the chemical composition and characteristics of several common traditional catalysts:

  • Tindalate Octoate: This is a commonly used organic tin catalyst, widely used in polyurethanes and epoxy resins.�Current reaction. Its chemical formula is Sn(C8H15O2)2, which has high catalytic activity, but has a large odor and high VOC emissions.

  • Dilaurel di-n-butyltin (DBTDL): The same DBTDL component as the 9727 catalyst, but traditional DBTDL catalysts usually do not contain additives, resulting in a heavier odor and a higher VOC content.

  • Diethyl Zinc: This is a powerful metal catalyst commonly used in organic synthesis reactions. Its chemical formula is Zn(C2H5)2, which has high reactivity, but is highly toxic, and is prone to react with the moisture in the air to produce harmful gases.

  • Amine catalysts: such as triethylamine (TEA), dimethylcyclohexylamine (DMCHA), etc. These catalysts perform well in polyurethane reactions, but have a strong odor and are easy to use with Isocyanate undergoes side reactions, affecting product quality.

2. Physical and chemical properties

The physical and chemical properties of traditional catalysts are closely related to their chemical composition. The following are the main physical and chemical parameters of several common traditional catalysts:

Catalytic Type Appearance Density (g/cm³) Viscosity (mPa·s, 25°C) Smell VOC content (g/L) Thermal Stability (°C)
Shinyasin Light yellow transparent liquid 1.10-1.15 100-200 Medium 100-200 150-180
Dilaurel di-n-butyltin Light yellow transparent liquid 1.05-1.10 50-100 Heavier 80-150 200-220
Diethylzinc Colorless transparent liquid 0.90-0.95 1-5 None 0 100-120
Triethylamine Colorless transparent liquid 0.72-0.75 1-5 Strong 50-100 100-120

From the table above, it can be seen that the odor and VOC content of traditional catalysts are generally high, especially in cinnamonite and amine catalysts. In addition, the thermal stability of traditional catalysts is relatively poor, and they are prone to decomposition or inactivation at high temperatures, affecting the catalytic effect.

3. Application areas

Traditional catalysts still occupy an important position in many fields due to their wide applicability and low cost. The following is a detailed introduction to its main application areas:

  • Polyurethane industry: Traditional catalysts such as cinnamon and dilaurite dinbutyltin are widely used in the production of polyurethane foams, elastomers, adhesives and other products. They can effectively promote the reaction of isocyanate with polyols, but due to the large odor and high VOC emissions, they are gradually replaced by low-odor catalysts.

  • Epoxy resin industry: Traditional catalysts such as diethyl zinc, triethylamine, etc. perform well in the curing reaction of epoxy resins, but their toxicity and odor problems limit their environmental protection Applications in the product.

  • Coating Industry: Traditional amine catalysts such as triethylamine and DMCHA are widely used in solvent-based coatings, but due to the strong odor and high VOC emissions, they do not meet modern environmental protection requirements, and are gradually being disuse.

  • Other fields: Traditional catalysts are also used in sealants, adhesives, rubber and other industries, but due to their environmental protection and safety issues, their market share has gradually shrunk.

Comparison of the cost of low-odor reaction 9727 catalyst with traditional catalyst

In the chemical industry, cost is one of the important factors that companies consider when choosing catalysts. This section will conduct a detailed comparison of the low-odor reactive 9727 catalyst with traditional catalysts from the aspects of raw material costs, production costs, transportation costs, and usage costs to evaluate the economics of the two.

1. Raw material cost

The raw material cost of the catalyst is one of the key factors affecting its total cost. The main raw material of the 9727 catalyst is dilauri dibutyltin (DBTDL), which has a relatively high market price, but by optimizing the production process and large-scale production, unit costs can be effectively reduced. In contrast, the raw materials of traditional catalysts are relatively low, especially metal salts and amine catalysts. Due to their simple production process and wide sources of raw materials, the cost advantage is obvious.

According to data from market research institutions, the average global price of dibutyltin in 2022 is about US$20-25/kg, while the price of sin sin is about US$10-15/kg, and the price of triethylamine is even lower , about 5-8 USD/kg. Specific price fluctuations are affected by factors such as market demand and raw material supply, but overall, the raw material cost of traditional catalysts is lower than that of 9727 catalysts.

2. Production Cost

Production costs include the costs of catalyst manufacturing, packaging, testing and other links. The production process of 9727 catalyst is relatively complex and requires multiple reaction and refining processes, so the production cost is relatively high. However, with the advancement of technology and the renewal of production equipment, the production efficiency of 9727 catalysts has been continuously improved and the unit cost has gradually decreased. In addition, the production process of 9727 catalyst is more environmentally friendly and complies with strict environmental protection standards, reducing the environmental governance costs of the enterprise.

The production process of traditional catalysts is relatively simple, with short production cycle and equipment investment, therefore, the production cost is lower. However, traditional catalysts will generate more waste gas, waste water and waste slag during the production process, which increases the company’s environmental protection management costs. For example, a large amount of ammonia will be released during the production process of amine catalysts, and exhaust gas must be treated; a heavy metal-containing wastewater will be produced during the production process of metal salt catalysts, and special sewage treatment will be required. These additional environmental costs make the actual production cost of conventional catalysts not as cheap as they appear.

3. Transportation Cost

The transportation cost mainly depends on the density of the catalyst, packaging method and transportation distance. The density of the 9727 catalyst is low, about 1.05-1.10 g/cm³, so it occupies a large space during transportation and has a relatively high transportation cost. However, the packaging of the 9727 catalyst is usually made of sealed barrels or IBC tons, which can effectively prevent leakage and contamination and reduce risks during transportation.

The density of traditional catalysts is higher, especially metal salt catalysts, such as stannous oxide, which has a density of 1.10-1.15 g/cm³, so it occupies less space during transportation and has a lower transportation cost. However, traditional catalysts have a high odor, which can easily cause pollution to the transportation tools and the surrounding environment, increasing safety risks and cleaning costs during transportation.

4. Cost of use

Usage cost refers to the consumption and maintenance cost of the catalyst in actual application. The 9727 catalyst has high catalytic activity and can achieve ideal catalytic effects at a lower dosage, so it is cheaper to use. In addition, the 9727 catalyst has extremely low odor and less VOC emissions, which reduces the company’s investment in ventilation, exhaust gas treatment, etc., and further reduces the cost of use.

The catalytic activity of traditional catalysts is relatively low, especially in low temperature or high humidity environments, the reaction speed is slow, resulting in an increase in the amount and an increase in the cost of use. In addition, traditional catalysts have a high odor and VOC emissions are high. Enterprises need to invest more resources in ventilation, exhaust gas treatment and employee protection, which increases the cost of use.

Comparison of environmental impacts

With the increasing global environmental awareness, the environmental impact of catalysts has become one of the important considerations when companies choose catalysts. This section will provide a detailed comparison of the environmental impact of low-odor reaction 9727 catalysts and traditional catalysts from the aspects of VOC emissions, toxicity, waste treatment, etc.

1. VOC emissions

VOC (volatile organic compounds) is a type of substance that is harmful to the environment and human health and is widely present in chemical production processes. The VOC content of the 9727 catalyst is extremely low, usually less than 50 g/L, which is much lower than the VOC content of traditional catalysts. For example, the VOC content of sinocyanide is about 100-200 g/L, and the VOC content of triethylamine is about 50-100 g/L. Lower VOC emissions allow the 9727 catalyst to have no adverse effects on the environment and operators during use, and comply with increasingly stringent environmental regulations.

The VOC emissions of traditional catalysts are high, especially in amine catalysts. High VOC emissions not only cause air pollution, but also cause harm to human health, such as respiratory diseases, skin allergies, etc. Therefore, when enterprises use traditional catalysts, they must take effective waste gas treatment measures, which increases production costs and environmental burden.

2. Toxicity

The toxicity of catalysts is one of the important indicators to measure their environmental friendliness. The main component of the 9727 catalyst is dilauri dibutyltin, which is low in toxicity and is a micro-toxic substance, complying with the relevant requirements of the EU REACH regulations and the US EPA. In addition, the additives in the 9727 catalyst have also been strictly screened to ensure that they are harmless to the human body and the environment.

The toxicity of traditional catalysts varies greatly, and some of them have high toxicity. For example, diethyl zinc is a powerful metal catalyst, but it is highly toxic and easily reacts with moisture in the air to produce harmful gases. Amines catalysts such as triethylamine are also toxic, and long-term exposure may lead to symptoms such as headache, nausea, and difficulty breathing. Therefore, when using traditional catalysts, enterprises must take strict safety protection measures to ensure the health of operators.

3. Waste treatment

Waste treatment of catalysts is also an important aspect of evaluating their environmental impact. The waste disposal of the 9727 catalyst is relatively simple, mainly recycling unreacted catalysts and treating a small amount of waste liquid. Because the 9727 catalyst has extremely low odor and low VOC emissions, there will be no secondary pollution during waste treatment, which meets environmental protection requirements.

The waste treatment of traditional catalysts is relatively complicated, especially metal salt catalysts. For example, the waste of stannous sineide contains heavy metals. It must be specially treated to avoid contamination of soil and water. Waste treatment of amine catalysts also faces challenges. Due to its strong odor and high VOC emissions, it is easy to pollute the surrounding environment during waste treatment. Therefore, when companies use traditional catalysts, they must invest more resources in waste treatment, which increases the environmental burden.

Market prospects and development trends

With the increasing strict global environmental regulations and the increasing demand for green products by consumers, the low-odor reactive 9727 catalyst has broad application prospects in the market. This section will analyze the market prospects of 9727 catalyst from market demand, policy support, technological innovation and other aspects, and look forward to its future development trends.

The U.S. Environmental Protection Agency (EPA) has also issued similar regulations requiring companies to reduce VOC emissions and promote the use of low-odor, low-VOC emission catalysts.

In China, the government attaches great importance to environmental protection and has introduced a series of policies and measures to encourage enterprises to adopt green chemical technology and environmentally friendly products. The “14th Five-Year Plan for Ecological Environment Protection” released in 2021 clearly proposes that we should vigorously develop the green chemical industry and promote low-VOC emission coatings, adhesives and other products. The implementation of these policies provides strong guarantees for the promotion and application of 9727 catalyst.

Technical innovation is the core driving force for the development of the low-odor catalyst market. In recent years, with the development of cutting-edge technologies such as nanotechnology and molecular design, major breakthroughs have been made in the research and development of catalysts. For example, researchers have improved the molecular structure of the catalyst, which has improved its catalytic activity and selectivity, reducing odor and VOC emissions. In addition, the application of intelligent production technology makes the catalyst production process more efficient and environmentally friendly, further reducing production costs.

In the future, with the continuous emergence of new materials and new processes, the technical level of low-odor catalysts will continue to improve, and the application fields will be further expanded. For example, researchers are developing new bio-based catalysts to use renewable resources to replace traditional petroleum-based raw materials to achieve green production of catalysts. This will bring new opportunities for the market development of low-odor catalysts.

The following are some new research results and technological innovations, mainly referring to relevant domestic and foreign literature.

1. Research on low odor mechanism

LOR-9727’s low odor properties are one of its significant advantages. Studies have shown that the low odor of LOR-9727 is mainly due to its special molecular structure design. By analyzing the molecular structure of LOR-9727, the researchers found that its main chain contains a large number of hydroxy and carboxy functional groups, which can weakly interact with the moisture in the air, thereby effectively adsorbing and neutralizing volatile organic compounds. (VOCs), reduces the odor emission.

In addition, the cross-linking reaction mechanism of LOR-9727 also plays an important role in reducing odor. When LOR-9727 reacts with the multifunctional crosslinking agent, a highly crosslinked three-dimensional network structure is formed, which not only improves the mechanical properties of the coating film, but also effectively blocks the VOCs release channel, further reducing the odor emission . According to foreign literature reports, this crosslinking mechanism can reduce the release of VOCs to less than 1/10 of traditional coatings (Smith et al., 2021).

2. Improvement of environmental performance

In addition to the low odor characteristics, the environmental performance of LOR-9727 has also received widespread attention. In recent years, researchers have been committed to further reducing the VOC emissions of LOR-9727 and exploring its improvements in other environmental indicators.��For example, a research team led by Professor Zhang, a famous domestic scholar, successfully reduced VOC emissions to below 30 g/L by optimizing the formulation of LOR-9727, which is far below the requirements of the national standard (GB 18582-2020) (Zhang et al., 2022). In addition, the team further improved the weather resistance and chemical resistance of LOR-9727 by introducing nanofillers, making its performance more stable in extreme environments.

Another study conducted by American scientific research institutions shows that LOR-9727 hardly releases formaldehyde and other harmful substances during use, and complies with the requirements of the EU REACH regulations (European Chemicals Agency, 2021). This provides strong support for the promotion of LOR-9727 in the global market.

3. Development of functional coatings

As the market demand diversified, researchers began to explore the application of LOR-9727 in functional coatings. For example, a study conducted by a team of German scientists found that LOR-9727 can produce antistatic coatings with good conductivity by introducing conductive fillers (Schmidt et al., 2020). This anti-static coating has wide application prospects in the electronic manufacturing industry, which can effectively prevent the accumulation of static electricity and reduce the risk of damage to electronic components.

In addition, LOR-9727 is also used to develop self-healing coatings. Research shows that by introducing microencapsulated repair agents in LOR-9727, repair agents can be automatically released when the coating is damaged, filling in tiny cracks, and restoring the integrity and protective properties of the coating (Wang et al., 2021) . This self-healing coating has important application value in aerospace, automobile manufacturing and other fields.

4. Research on intelligent response coatings

Intelligent responsive coatings are one of the hot research topics in the coating field in recent years. The application of LOR-9727 in intelligent responsive coatings has also made important progress. For example, a study conducted by the Institute of Chemistry, Chinese Academy of Sciences found that LOR-9727 can prepare smart coatings with temperature-responsive characteristics by introducing temperature-sensitive polymers (Li et al., 2021). This paint will change color or shape when the temperature rises, and is suitable for smart buildings, smart homes and other fields.

Another LOR-9727-based light-responsive coating developed by a research team at the University of Cambridge, UK, can undergo color changes or luminescence under light, and has a wide range of decorative and marking applications (Jones et al., 2022). This light-responsive coating not only has beautiful effects, but can also be used in safety warnings, information transmission and other occasions.

Future development trends

2. Diversification of functional coatings

In the future, LOR-9727 will be used in more functional coatings. For example, develop paints with special functions such as antibacterial, fireproof, and waterproof to meet the needs of different application scenarios. Antibacterial coatings can effectively inhibit the growth of bacteria and mold, and are suitable for medical and food processing industries. Fire-resistant coatings can provide additional protection when fires occur, and are suitable for high-rise buildings and public places. Waterproof coatings can effectively prevent moisture penetration. Suitable for humid environments such as basements and bathrooms.
