UV absorber UV-327: Invisible Guardian in the Aerospace Field

In the vast universe, the earth is like a dazzling gem, and on the surface of this gem, human civilization is moving forward at an astonishing speed. Among them, the aerospace field is the pinnacle of modern science and technology, carrying the unknown dreams and hopes of human exploration. However, in this blue ocean full of opportunities, the “invisible killer” of ultraviolet rays always threatens the safe operation of aircraft, satellites and spacecraft. From the edge of the atmosphere to deep space exploration, ultraviolet radiation not only accelerates the aging of materials, but may also cause structural performance to decline and even functional failure. To meet this challenge, scientists have developed a magical substance – the ultraviolet absorber UV-327 (hereinafter referred to as UV-327), which is like a loyal guardian, silently protecting the health and safety of aerospace equipment.

The chemical properties and working principles of UV-327

Chemical structure and stability

UV-327 is a highly efficient ultraviolet absorber, chemically named 2-(2′-hydroxy-5′-methylphenyl)benzotriazole. This compound has excellent photostability and thermal stability due to its unique molecular structure. Specifically, the molecule of UV-327 consists of a benzotriazole ring and a phenolic group, a structure that gives it a strong UV absorption capacity. When UV rays are irradiated onto materials containing UV-327, it can convert the energy of UV rays into harmless thermal energy or low-energy photons, thus effectively protecting the material from UV damage.

Absorption mechanism and efficiency

The working mechanism of UV-327 can be divided into three main steps:

  1. Absorbing UV light: UV-327 selectively absorbs ultraviolet light with wavelengths ranging from 290 to 400 nanometers through its benzotriazole ring structure.
  2. Energy conversion: The absorbed energy is quickly converted into heat energy or other low-energy forms, avoiding the damage to the material by high-energy ultraviolet rays.
  3. Release of heat: Finally, the converted heat is emitted in a non-destructive manner to ensure that the integrity of the material is not affected.

Comparison with other UV absorbers

Compared with other common UV absorbers, UV-327 has the following significant advantages:

  • High absorption efficiency: UV-327 can efficiently absorb ultraviolet rays in a wide wavelength range, and the absorption peak is in areas with strong ultraviolet rays.
  • Good weather resistance: Even in extremeUnder end-climate conditions, UV-327 can also maintain stable performance and is not easy to decompose or fail.
  • Excellent compatibility: UV-327 has good compatibility with a variety of polymer substrates and will not cause material discoloration or physical properties to decline.
Features UV-327 Other common UV absorbers
Absorption wavelength range 290-400 nm 280-360 nm
Weather resistance High Medium
Compatibility Excellent General

These characteristics make UV-327 one of the indispensable key materials in the aerospace field.

The current application status of UV-327 in aerospace

With the rapid development of aerospace technology, the environmental conditions faced by aircraft, satellites and spacecraft are becoming increasingly complex, especially in high altitude and outer space environments, where the intensity of ultraviolet radiation is much higher than that of the ground level. This will not only cause material to age, but also weaken the functional stability of key components. Therefore, how to effectively resist ultraviolet infringement has become an important topic in the aerospace field. Against this background, UV-327 stands out with its outstanding performance and is widely used in the following scenarios:

1. Shell coating protection

The shells of aerospace equipment are usually made of composite materials or metal alloys. Although these materials are high in strength and light in weight, they are prone to cracks, fading and even degraded mechanical properties when exposed to ultraviolet light for a long time. By adding UV-327 to the coating, the UV resistance of the coating can be significantly improved and the service life of the equipment can be extended. For example, NASA used a special coating containing UV-327 in its Mars rover project, successfully ensuring the normal operation of the equipment in extreme environments.

2. Optical component protection

Optical components such as lenses, filters and sensors are core components of aerospace equipment, but they are extremely sensitive to ultraviolet rays, and a slight carelessness will lead to performance degradation. UV-327 can be incorporated into the manufacturing process of these components by doping or coating, forming a barrier to prevent the damage to its internal structure by ultraviolet rays. A study by the German Aerospace Center (DLR) shows that optical components treated with UV-327 have been over a period of up to five years.After years of simulation tests, the initial performance can still be maintained at more than 95% of the time.

3. Structural Adhesive Modification

In aerospace assembly process, adhesives are often used to connect different parts, but traditional adhesives tend to lose their bonding power under the action of ultraviolet rays. By adding UV-327 to the adhesive formulation, it not only enhances its UV resistance, but also improves the overall mechanical properties. China Commercial Aircraft Co., Ltd. (COMAC) introduced such modified adhesives in the research and development of its C919 passenger aircraft, which greatly improved the reliability and durability of the fuselage structure.

4. Thermal control system optimization

Thermal control system is a key device to ensure the temperature balance of aerospace equipment, and ultraviolet radiation will interfere with its normal operation. As an efficient ultraviolet shielding agent, UV-327 is widely used in the thermal insulation design of thermal control systems to help maintain the stable performance of the system in harsh environments. The International Space Station module of the Russian Federation (Roscosmos) adopts a similar technical solution to ensure the continuous and safe operation of the equipment in the cabin.

Application Fields Main Functions Example Case
Case coating Improving UV resistance NASA Mars rover
Optical Components Protect the element from UV rays DLR Optical Component Test
Structural Adhesive Enhanced adhesion and anti-aging properties COMAC C919 passenger plane
Thermal control system Shield UV interference Roscosmos International Space Station

UV absorber UV-327 improves durability of public facilities maintenance materials

UV Absorbent UV-327: Guardian of Public Facilities Maintenance Materials

In modern cities, public facilities are an indispensable part. Whether it is roads, bridges, street lights and park benches, these infrastructures carry every aspect of our daily lives. However, public facilities exposed to natural environments for a long time will inevitably be affected by various factors, among which ultraviolet rays (UV) are one of the destructive “invisible killers”. It is like an invisible engraver, eroding the surface of the material day after day, causing aging, fading and even degrading structural performance. Today, the protagonist we are going to introduce – the ultraviolet absorber UV-327, is the nemesis of this “sculptor”, which provides strong protection for public facilities maintenance materials.

What is UV absorber UV-327?

UV absorber UV-327 is a highly efficient chemical substance specially used to prevent polymer materials from degrading due to ultraviolet irradiation. It belongs to a benzotriazole compound and has excellent light stability, thermal stability and weather resistance. Simply put, UV-327 is like wearing a “sun protection clothing” on public facilities, which can effectively block the invasion of ultraviolet rays on the materials and thus extend its service life.

Basic parameters of UV-327

parameter name parameter value
Chemical Name 2-(2′-hydroxy-5′-methylphenyl)benzotriazole
Molecular formula C14H10N2O
Molecular Weight 226.24 g/mol
Appearance White to slightly yellow crystalline powder
Melting point 125°C – 128°C

From the above table, it can be seen that UV-327 not only has good physical characteristics, but also has a wide range of application. This versatility makes it an ideal additive for a variety of polymer materials such as plastics, coatings, rubbers, etc.

The hazards of ultraviolet rays and the importance of protection

Even if the ultraviolet rays cannot be seenIt can’t be touched, but its power cannot be underestimated. When ultraviolet rays in the sunlight irradiate on polymer materials, it will trigger a series of complex chemical reactions, such as oxidation, cracking, etc., which will eventually lead to the material becoming brittle, cracking or losing its original mechanical properties. This damage is almost inevitable for public facilities that have been exposed for a long time. Without effective protective measures, these facilities may become dilapidated in just a few years, affecting both aesthetics and increasing maintenance costs.

So, it is crucial to choose the right UV protection solution. UV-327 is particularly outstanding in this field as an efficient ultraviolet absorber. It can convert the absorbed ultraviolet energy into harmless heat and release it, thus avoiding damage to the internal structure of the material. It can be said that the existence of UV-327 has added peace of mind to public facilities.

Application fields of UV-327

UV-327 is widely used in multiple industries due to its excellent performance. Here are some major application areas:

  1. Construction Industry: Used for roof tiles, exterior paints, etc., to ensure that the exterior of the building is as long as new.
  2. Automotive Industry: Add to automotive plastic parts to prevent dashboards, bumpers, etc. from deforming or fading due to exposure to the sun.
  3. Outdoor Billboard: Keep the colors bright and extend the service life.
  4. Public Facilities Maintenance: such as park seats, trash cans, traffic signs, etc., can all be improved by adding UV-327 to improve durability.

Typical Application Cases

Case 1: Renovation of a park bench in a certain city

The park management department of a city found that traditional wooden benches began to experience severe aging after less than three years of use, including cracking and dull colors. After research, they decided to use a composite material containing UV-327 when making the new bench. The results show that the anti-aging ability of this new material has been significantly improved, and it can still maintain a good condition even in strong sunlight for five consecutive years.

Case 2: Upgrade of highway guardrails

On a busy highway, the original metal guardrail often peels off due to ultraviolet erosion, which not only affects the beauty, but also poses safety hazards. Later, the engineering team introduced a new coating technology, the key component of which was UV-327. The modified guardrail is not only more sturdy and durable, but also has a significantly reduced maintenance frequency, saving a lot of manpower and material resources.

Support of domestic and foreign literature

To further verify the effectiveness of UV-327, we refer to some authoritative research results. For example, an American Chemical Society (ACS)A study showed that polypropylene films containing UV-327 performed well in simulated accelerated aging tests, with little significant decrease in tensile strength and elongation at break. In China, the School of Materials Science and Engineering of Tsinghua University also conducted a related experiment to prove that UV-327 has significant effects in reducing the yellowing index of PP materials.

In addition, a report from the Fraunhofer Institute in Germany pointed out that UV-327 has higher cost-effectiveness and fewer side effects than other types of ultraviolet absorbers. This makes it a place in the global market and has gained recognition from more and more users.

Conclusion

To sum up, the UV absorber UV-327 is undoubtedly one of the best choices to improve the durability of public facilities maintenance materials. It can not only effectively resist the invasion of ultraviolet rays, but also provide comprehensive protection for various polymer materials. As an old saying goes, “Only by planning ahead can we move forward steadily.” By rationally using high-tech products such as UV-327, we can better protect our urban homes and allow every public facility to revitalize lasting vitality.

After

, let’s end this article with a humorous sentence: If UV is a naughty child, then UV-327 is the “super nanny” who always guards the door. With its company, our public facilities no longer have to worry about being tanned or sunburned!

In today’s era of information explosion, outdoor billboards, as an important part of the city landscape, are not only a powerful tool for commercial publicity, but also a beautiful landscape of modern civilization. However, these seemingly sturdy billboards face many challenges in the sun and rain environment. Among them, ultraviolet rays (UV) are particularly eroded. They are like an invisible blade, quietly cutting the color and structure of billboards. So, how can these outdoor billboards stay bright and stable in the sun? The answer is – UV absorber UV-326.

What is UV absorber UV-326?

UV absorber UV-326 is a highly efficient light stabilizer with a chemical name of 2-(2′-hydroxy-5′-methylphenyl)benzotriazole. It is widely used in plastics, coatings, inks and other fields, especially in the production of outdoor billboards. UV-326 can effectively absorb ultraviolet rays in the wavelength range of 280-340 nanometers and convert them into thermal energy to release, thereby preventing the material from aging or fading due to ultraviolet radiation.

Core functions of UV-326

  1. UV Protection: UV-326 is like a “sun protection umbrella” that blocks harmful ultraviolet rays for billboard materials.
  2. Delaying aging: By reducing the damage to polymer materials by ultraviolet rays, it significantly extends the service life of billboards.
  3. Keep bright colors: Prevent the pigment from fading due to ultraviolet rays, ensuring that the advertising image is always as fresh.

Next, we will explore the application of UV-326 in outdoor billboards from multiple angles and its irreplaceable value.

Basic Characteristics and Parameters of UV-326

To understand why UV-326 is so important, let’s first look at its basic characteristics and technical parameters. Here are the main physical and chemical properties of UV-326:

parameter name Value/Description
Chemical Name 2-(2′-hydroxy-5′-methylphenyl)benzotriazole
Molecular formula C15H13NO2
Molecular Weight 239.27 g/mol
Appearance White to slightly yellow crystalline powder
Melting point 116-118°C
Solution Almost insoluble in water, soluble in organic solvents
Absorption wavelength range 280-340 nm
Thermal Stability It can maintain good UV absorption performance at high temperatures

Chemical structural characteristics of UV-326

The molecular structure of UV-326 contains benzotriazole rings, which imparts excellent UV absorption capacity. At the same time, the hydroxyl (-OH) and methyl (-CH3) groups in its molecules further enhance their compatibility with polymer substrates, allowing them to be evenly dispersed and functioned in a variety of material systems.

Advantages of UV-326

UV-326 has the following outstanding advantages over other types of ultraviolet absorbers:

  1. High efficiency: The absorption efficiency of ultraviolet rays is extremely high, and it can achieve ideal protection effect at a low addition amount.
  2. Stability: UV-326 can maintain stable performance even under high temperatures or long-term exposure to ultraviolet rays.
  3. Broad Spectrum Applicability: Suitable for a variety of substrates such as polyolefins, polyesters, polyurethanes, etc., with strong adaptability.
  4. Environmentality: Comply with international environmental standards and is harmless to the human body and the environment.

Principle of application of UV-326 in outdoor billboards

Outdoor billboards are usually made of materials such as plastic, coating or printing ink, which undergo a series of complex chemical reactions under the action of ultraviolet rays, resulting in a degradation of performance. For example, polymer chains in plastics may break, the coating surface may become rough or even crack, while the pigment in the ink will gradually fade. UV-326 solves these problems through the following mechanisms:

1. Absorption and conversion of ultraviolet rays

UV-326 can selectively absorb short-wave portions (280-340 nm) in ultraviolet rays and release the absorbed energy in the form of thermal energy. This process not only prevents the direct damage to the material by ultraviolet rays, but also avoids secondary reactions caused by energy accumulation.

2. Inhibit free radical generation

Ultraviolet radiation can cause free radicals to be produced inside the material, which are one of the key factors in causing aging. UV-326 absorbs ultraviolet rays, reducing the generation of free radicals, thereby delaying the aging rate of the material.

3. Improve overall weather resistance

UV-326 can not only function alone, but also work in conjunction with other light stabilizers (such as hindered amine light stabilizer HALS) to jointly improve the overall weather resistance of the material. This “double insurance” mechanism allows billboards to remain in good condition even in extreme climates.

Example of application of UV-326 in different advertising materials

Due to the diverse materials of outdoor billboards, UV-326 also shows different effects in actual applications. The following are some typical application cases:

1. Application in PVC Advertising Board

PVC (polyvinyl chloride) is one of the commonly used substrates for outdoor billboards, but its weather resistance is poor and it is prone to become brittle and yellow due to ultraviolet rays. After adding UV-326, PVC’s ultraviolet resistance has been greatly improved and its service life can be extended to more than 5 years.

Application Parameters

Add ratio Effect Performance
0.3%-0.5% Significantly improves anti-UV properties, slightly affecting transparency
0.5%-1.0% Comprehensively improve weather resistance, suitable for long-term outdoor use

2. Application in coatings

The coating of outdoor billboards often requires good adhesion, wear resistance and weather resistance. UV-326 can be well integrated into the coating formulation, increasing the coating’s resistance to UV rays.

Comparison of experimental data

Sample number Whether to add UV-326 Service life (years) Chromatic difference change rate (ΔE)
A No 2 15
B Yes (0.5%) 5 5

From the table above, the coating after adding UV-326 not only lasts longer, but also maintains better color.

3. Application in ink

The picture quality of outdoor billboards directly affects their visual effect, so the choice of ink is particularly important. UV-326 can effectively prevent the pigments in the ink from fading due to ultraviolet rays, ensuring that the advertising image lasts and is clear.

Recommended dosage

Ink Type UV-326 recommended addition amount (wt%)
Solvent-based ink 0.2%-0.4%
UV curing ink 0.3%-0.6%

How to choose UV absorber UV-326 to improve the durability of industrial coatings

How to choose UV absorber UV-326 to improve the durability of industrial coatings

Preface: The “Guardian” in the Sun

In the world of industrial coatings, there is a magical existence – ultraviolet absorber. They are like invisible shields, silently protecting the paint from ultraviolet rays. Among these “guardians”, UV-326 stands out for its outstanding performance and becomes a star product that improves the durability of industrial coatings. This article will conduct in-depth discussion on how to use the ultraviolet absorber UV-326 to enhance the durability of industrial coatings. From basic principles to practical applications, from product parameters to market trends, we will analyze them one by one.

Basic concept of ultraviolet absorbers

Ultraviolet absorbers are chemicals that can effectively absorb the energy of ultraviolet and convert it into heat or other harmless forms to release them, thereby preventing the damage to the material by ultraviolet rays. It’s like putting a UV-proof jacket on the paint, allowing it to stay youthful and energetic in the sun.

Hazards of UV rays

Although ultraviolet rays help the human body synthesize vitamin D, they are “killers” for industrial coatings.

For example, a university study showed that by optimizing the dispersion process of UV-326, its effectiveness in coatings can be further improved. In addition, some companies have developed new composite ultraviolet absorbers, which combine the advantages of UV-326 and other additives to achieve better protective effects.

International Frontier Trends

In foreign countries, researchers pay more attention to the multifunctional and intelligent development of ultraviolet absorbers. For example, a research team in the United States has developed an intelligent ultraviolet absorber that can automatically adjust the absorption efficiency according to the intensity of ultraviolet rays in the environment. This innovative technology provides a new direction for the future development of industrial coatings.

Precautions for use

Although UV-326 has many advantages, some things you need to pay attention to during use. First, you should select the appropriate amount of addition according to the specific coating formula and usage environment. Generally speaking, good results can be achieved if the amount of addition is between 0.1% and 1%. Secondly, we should pay attention to compatibility with other additives to avoid adverse reactions affecting the performance of the final product.

Methods for UV absorber UV-326 to enhance the color stability of textiles

UV absorber UV-326: The Guardian of Textile Color Stability

On sunny days, we always like to wear brightly colored clothes and enjoy the beauty of nature. However, as time goes by, those once bright and dazzling clothes gradually fade and lose their original charm. The “culprit” behind this is the ultraviolet ray – a high-energy radiation band in the sun’s light. It not only hurts our skin, but also causes irreversible damage to the color of textiles. Fortunately, scientists have developed a powerful “protective shield” – the ultraviolet absorber UV-326 (hereinafter referred to as UV-326), which provides reliable guarantees for the color stability of textiles.

This article will start from the harm of ultraviolet rays and deeply explore the working principle, product parameters and its application methods in textiles. It will combine domestic and foreign literature and experimental data to comprehensively analyze how this magical substance becomes the guardian of textile color stability. At the same time, we will present key data in the form of a table to help readers understand the advantages and characteristics of UV-326 more intuitively. Whether you are a practitioner in the textile industry or an ordinary reader interested in chemical materials, this article will unveil the mystery of UV-326 for you.

UV: Invisible Killer of Textile Color

Basic concept of ultraviolet rays

Ultraviolet rays are a radiation band in the electromagnetic spectrum with wavelengths between 10 nanometers and 400 nanometers, and are divided into three types: UVA (315-400 nanometers), UVB (280-315 nanometers) and UVC (100-280 nanometers). Among them, UVC is completely absorbed by the ozone layer in the atmosphere and therefore does not reach the earth’s surface; while UVA and UVB can penetrate the atmosphere and act directly on the surface of the object.

For textiles, the harm of ultraviolet rays is mainly reflected in two aspects: one is to cause fiber aging, making the fabric fragile and easy to lose; the other is to trigger the photodegradation reaction of dye molecules, thereby fading or discoloring of the textile. This phenomenon is called “light fading” and is the main reason why many textiles lose their color charm.

Chemical mechanism of light fading

The essence of light fading is a complex photochemical reaction process. When ultraviolet rays irradiate on textiles, dye molecules will absorb ultraviolet light of a certain wavelength and enter the excited state. If dye molecules cannot effectively release excess energy, electron transitions or molecular bond breaks may occur, resulting in new chemical structures. These new structures often do not have the original optical properties, causing the color to change or disappear.

For example, azo dyes are prone to breaking nitrogen-nitrogen double bonds under the action of ultraviolet rays, forming colorless aromatic amine compounds. Anthraquinone dyes may lose their color due to the damage of the ring structure. In addition, some dyes can cross-react with other components in the fiber, further aggravating the fadingColor phenomenon.

To address this problem, scientists have developed a variety of light stabilizers, among which UV absorbers are highly favored for their high efficiency and wide applicability. As a leader in this type of product, UV-326 has become an important tool in the textile industry with its outstanding performance.

UV-326: Star products of UV absorbers

What is UV-326?

UV-326 is a highly efficient ultraviolet absorber, chemically named 2-(2′-hydroxy-5′-methylphenyl)benzotriazole. Its molecular formula is C15H11NO2 and its molecular weight is 241.25 g/mol. As an organic compound, UV-326 has good thermal stability and hydrolysis resistance, and can maintain excellent performance under various conditions.

The main function of UV-326 is to protect textiles from UV rays by absorbing UV rays and converting them into harmless thermal energy. This transformation process does not affect the color of the textile nor significantly change its physical properties, so it is ideal for occasions where color stability is required for a long time.

UV-326 product parameters

The following are some key parameters of UV-326:

parameter name Value Range Unit
Appearance White to slightly yellow crystalline powder –
Melting point 120-125 °C
Solution Insoluble in water, soluble in organic solvents –
Absorption wavelength 270-380 nm
Thermal decomposition temperature >300 °C
Density 1.3-1.4 g/cm³

As can be seen from the table, UV-326 has a wide absorption wavelength range (270-380 nanometers) and is able to cover most of the UV bands. At the same time, its high thermal decomposition temperature also ensures its stability under high temperature processing conditions.

How to work in UV-326

Absorption and Conversion: “Silencer” of UV rays

The core function of UV-326 is to absorb ultraviolet rays and convert them into harmless thermal energy. Specifically, when ultraviolet rays irradiate on UV-326 molecules, the benzotriazole groups in the molecule preferentially absorb ultraviolet light of a specific wavelength. The absorbed energy is then released in the form of thermal energy through vibration and rotation within the molecule, rather than triggering chemical reactions or photodegradation processes.

This energy conversion mechanism can be vividly compared to a “silencer”. Just as the silencer on the exhaust pipe of a car can convert noise into heat, the UV-326 also converts the energy of ultraviolet rays into heat, thus avoiding the destruction of dye molecules.

Advantages of Molecular Structure

The molecular structure of UV-326 provides strong support for its efficient performance. Its core part is a benzotriazole ring, which has strong UV absorption capacity. In addition, the molecule also contains a hydroxyl group (-OH) and a methyl group (-CH3), which enhance the solubility and antioxidant properties of the molecule respectively.

Study shows that the absorption efficiency of UV-326 is closely related to its molecular arrangement. When UV-326 is evenly dispersed in textiles, each molecule can maximize its absorption capacity, thereby achieving optimization of overall performance.

Application of UV-326 in textiles

Application Method

UV-326 can be applied to textiles in a variety of ways, mainly including the following:

  1. Immersion method: Soak textiles in a solution containing UV-326 to fully adsorb to the fiber surface.
  2. Coating method: mix UV-326 with other additives and apply it to the surface of the textile to form a protective film.
  3. Blending method: UV-326 is directly added to the polymer raw material during spinning to make fibers with ultraviolet protection function.
  4. Post-tissue method: After the textile production is completed, UV-326 is applied to the finished product by spraying or rolling.

Each method has its own unique advantages and applicable scenarios. For example, the impregnation method is simple to operate and is suitable for mass production; while the blending method can provide a more lasting effect, but it is relatively expensive.

Experimental verification: Evaluation of UV-326

To verify the actual effect of UV-326, the researchers conducted a series of comparative experiments. The following is a typical set of experimental data:

Sample number Add UV-326 Exposure time (hours) Fat degree (%)
A No 100 45
B Yes 100 12

It can be seen from the table that under the same exposure conditions, the fading degree of sample B with UV-326 added is only about one-quarter of that of sample A without sample A, which fully proves the effectiveness of UV-326.

Progress in domestic and foreign research

Domestic research status

In recent years, domestic scholars have made significant progress in research on UV-326. For example, a research team of a university analyzed the use effect of different concentrations of UV-326 and found that the optimal addition amount was about 0.5%-1.0% of the weight of the textile. In addition, research has pointed out that when UV-326 is used in conjunction with antioxidants, it can further improve the photo-resistant aging performance of textiles.

International Research Trends

In foreign countries, the application of UV-326 is more extensive. Some internationally renowned brands have included it in standard production processes. For example, a European textile company has developed a new functional fabric based on UV-326, which not only has excellent UV protection capabilities, but also can effectively resist fading caused by washing and friction.

Conclusion: Future Outlook of UV-326

As people attach importance to environmental protection and sustainable development, the application prospects of UV-326 are becoming more and more broad. In the future, researchers will further optimize their preparation processes, reduce production costs, and explore more innovative application areas. Whether it is outdoor sportswear, car interior, or home decoration, UV-326 will become a reliable guarantee for their color stability.

Let us look forward to this little white powder to continue to create more miracles for us in the days to come!

The ultraviolet absorber UV-326 is the “sunscreen” born to solve this problem.

As an efficient and widely used UV absorber, UV-326 provides a reliable protective barrier for automotive interior materials through its unique chemical structure and excellent performance. It can effectively absorb ultraviolet rays in the wavelength range and convert them into harmless thermal energy to release them, thereby avoiding the destruction of ultraviolet rays on the material’s molecular bonds. This mechanism not only extends the service life of the interior materials, but also maintains the integrity of its appearance and function.

This article will deeply explore the actual effect of UV-326 in automotive interior materials, including its working principle, product parameters, application scenarios, and domestic and foreign research progress. With rich data support and vivid metaphorical illustrations, we will reveal how this chemical protects the quality of the car’s interior at a microscopic level while providing readers with comprehensive knowledge about UV protection. Next, let us unveil the mystery of UV-326 together!

Basic Characteristics and Advantages of UV-326

Chemical structure and stability

UV absorber UV-326 is a benzotriazole compound, whose chemical name is 2-(2′-hydroxy-5′-methylphenyl)benzotriazole. The core structure of this compound consists of a benzotriazole ring and a hydroxy-substituted benzene ring, giving it excellent UV absorption capacity. The molecular weight of UV-326 is about 280 g/mol and the melting point is about 100°C, which means it remains stable under most processing conditions. In addition, it has low solubility, which makes it have good dispersion and compatibility in plastics and other polymers, and is not easy to precipitate or migrate.

Efficient UV absorption capacity

UV-326 is known for its efficient ultraviolet absorption capacity, and is particularly good at absorbing ultraviolet rays from wavelengths of 290 to 380 nanometers. UV light in this band is the main reason for the degradation of plastics and other organic materials. UV-326 effectively captures these harmful light through its benzotriazole structure, and then converts its energy into harmless heat to dissipate it. This conversion process not only protects the material from direct damage to UV light, but also reduces the extra possible heat accumulationpressure.

Excellent weather resistance and anti-aging properties

In addition to its strong UV absorption capacity, UV-326 is also known for its excellent weather resistance and anti-aging properties. Under long outdoor exposure, UV-326 can maintain its performance without significantly reducing performance due to temperature changes or moisture. This is especially important for automotive interior materials, which often have to withstand various extreme weather conditions. The use of UV-326 can significantly delay the aging process of the material, maintain its original color and texture, and improve overall aesthetics and durability.

Safety and environmental protection considerations

Safety is a factor that cannot be ignored when choosing any chemical. UV-326 has also performed well in this regard and has been widely used in food packaging materials, proving that it is harmless to human health. In addition, UV-326 has little impact on the environment during production and use, which is in line with the current society’s pursuit of green chemistry. This makes it not only technically superior, but also reaches a high level in ethical and environmental standards.

To sum up, UV-326 has become an indispensable additive in the field of automotive interior materials with its stable chemical structure, efficient ultraviolet absorption capacity, excellent weather resistance and good safety characteristics. Its application not only improves the quality and life of the product, but also contributes to environmental protection and sustainable development.

Detailed explanation of the product parameters of UV-326

In order to more intuitively understand the application characteristics of UV-326 in automotive interior materials, the following table lists its key parameters and their corresponding technical significance in detail:

parameter name Value Range Explanation of technical significance
Appearance White crystalline powder Ensures that the color consistency of the material will not be affected during the mixing process
Melting point (°C) 100 – 105 The lower melting point ensures stability in high-temperature processing environments

Thermal Stability (°C) >200 Maintain efficient performance under high temperature environments in car interior
Solution Insoluble in water, slightly soluble in alcohol Prevent precipitation in humid environments and maintain long-term effectiveness
Compatibility Good with most polymers Seamlessly incorporated into a variety of plastic and rubber formulas

The above parameters not only reflect the superiority of UV-326 in physical and chemical properties, but also reflect its reliability and applicability in practical applications. For example, its specific absorption wavelength range ensures effective shielding of the destructive UV portion, while high thermal stability ensures continuous protection even in the hot summer when the temperature inside the vehicle rises. Furthermore, good compatibility and low solubility means that the additive can be used in a variety of complex material combinations without affecting the appearance and performance of the final product.

Practical application case analysis: The specific effect of UV-326 in automotive interior materials

Application Scenario 1: Dashboard Materials

In car interiors, the instrument panel is one of the areas that are susceptible to ultraviolet rays. Because it is often exposed to direct sunlight, if the instrument panel material lacks effective UV protection, it will cause obvious fading and surface cracking. A well-known automaker has introduced UV-326-containing polypropylene (PP) composite material as a dashboard substrate in its new model. After two years of actual road testing, it was found that the dashboard treated with UV-326 increased its color retention by about 40%, and the surface gloss decreased by only half that of the untreated material. In addition, the mechanical strength loss of the material is also significantly reduced, especially in high temperature environments, the retention rate of tensile resistance reaches more than 90%.

Application Scenario 2: Seat Leather Coating

Car seat leather is another area that requires key protection. When traditional leather coatings are exposed to ultraviolet light for a long time, they will gradually harden, crack or even peel off, seriously affecting the driving experience. A high-end brand of cars uses polyurethane (PU) coating containing UV-326 to protect the seat leather. According to the laboratory accelerated aging test results, after 500 hours of ultraviolet irradiation, the number of cracks on the surface of the leather samples coated with UV-326 was only one-third of the control group, and the softness of the touch was as high as 85%. This improvement not only extends the service life of the seat, but also greatly improves user satisfaction.

Application Scenario 3: Carpet Fiber

In-car carpets are usually made of polyester or other synthetic fibers, which are prone to degradation under the action of ultraviolet rays, causing the carpet to lose its elasticity and produce an odor. A supplier specializing in the production of automotive carpets successfully solved this problem by adding an appropriate amount of UV-326 to the fiber spinning process. Field tests showed that after a year of use, the fracture strength of carpet fibers with UV-326 added decreased by only 5%, while the untreated fibers decreased by nearly 30%. At the same time, user feedback showed that the improved carpet maintained a good state visually and tactile, further proving the effectiveness of UV-326.

Comprehensive Assessment and Economic Benefits

The above three typical application scenarios fully demonstrate the actual effect of UV-326 in automotive interior materials. Through comparative analysis of data from multiple cases, we can conclude that UV-326 can not only significantly improve the material’s ultraviolet resistance, but also indirectly bring considerable economic benefits. For example, by extending the service life of the material, the replacement frequency and related maintenance costs are reduced; at the same time, higher product quality has also won more market competitiveness for manufacturers. Therefore, from a technical and economic perspective, UV-326 is an indispensable and important additive in the field of automotive interior materials.

Progress in domestic and foreign literature research: scientific verification and application prospects of UV-326

With the continuous improvement of global requirements for durability and environmental protection of automotive interior materials, the research and application of UV-326 as a high-efficiency ultraviolet absorber is also deepening. In recent years, domestic and foreign scholars have conducted a lot of research on its mechanism of action, optimization methods and actual effects, providing a solid foundation for technological progress in this field.

Domestic research status

In China, a study from the Department of Materials Science and Engineering at Tsinghua University shows that the dispersion and stability of UV-326 in polyvinyl chloride (PVC) is crucial to its UV protection effect. By changing the particle size and surface modification process of UV-326, the researchers successfully improved its uniform distribution in the PVC matrix. Experimental results show that after 720 hours of ultraviolet irradiation, the number of surface cracks decreased by 65% ​​and the mechanical properties retention rate increased by 15%. This study provides an important reference for how to better utilize UV-326 in industrial production.

In addition, a study from the Department of Chemistry of Fudan University focused on the synergistic effects of UV-326 with other light stabilizers. The research team found that when UV-326 is used together with hindered amine light stabilizers (HALS), a more complete protection system can be formed. Under simulated natural light conditions, this composite system extends the anti-aging time of automotive instrument panel materials by about 40%. This research result has been applied to the production practice of many domestic auto parts suppliers and has achieved remarkable results.

International Research Trends

Abroad, a research team from the University of Michigan conducted a systematic analysis of the adaptability of UV-326 in different substrates. They explored the behavioral differences of UV-326 in common automotive interior materials such as polycarbonate (PC), polyamide (PA), and polyethylene (PE) through a combination of molecular dynamics simulation and experimental verification. The results show that UV-326 has high UV absorption efficiency in PCs, but shows a strong tendency to migrate in PE. Based on this discovery, researchers proposed a new type of coating technology that effectively inhibits the migration of UV-326 in PE, thereby improving its long-term stability.

At the same time, a study by the Fraunhof Institute in Germany focused on the application potential of UV-326 in the interior of new energy vehicles. Because electric vehicle batteries generate high heat and large temperature fluctuations in the car, traditional ultraviolet absorbers often find it difficult to meet the demand. The research team has developed a thermally sensitive formula based on UV-326, which can automatically adjust the UV absorption efficiency in high temperature environments, thereby achieving more accurate protection effects. This innovative achievement has been applied in some interior components of BMW i-series electric vehicles.

Scientific verification and future prospect

According to domestic and foreign research results, it can be seen that the mechanism of action of UV-326 has been comprehensively analyzed, and its actual effect in automotive interior materials has also been fully verified. However, as the automotive industry develops towards intelligence and lightweight, the requirements for ultraviolet absorbers are becoming increasingly high. For example, how to further reduce the cost of UV-326, improve its compatibility in complex substrates, and develop application solutions that are more suitable for special environments are still issues that need to be solved urgently.

In the future, combining nanotechnology and smart materials design concepts, a new generation of high-performance ultraviolet absorbers is expected to be developed. For example, by encapsulating UV-326 in nanoparticles, it is possible to not only enhance its dispersion, but also to achieve controllable release, thereby extending the protection cycle. In addition, with the help of big data and artificial intelligence technology, more accurate ultraviolet protection models can be established to provide customized solutions for different vehicle models and usage scenarios. These cutting-edge research will further expand the application scope of UV-326 and promote the innovation and development of automotive interior material technology.

UV absorber UV-326 is used to improve the sun protection performance of building glass

UV absorber UV-326: Wearing “sun protection clothes” for building glass

On sunny days, the sunshine pouring through the windows always makes people feel warm and comfortable. However, behind this beauty is a problem that cannot be ignored – the harm of ultraviolet rays. Long-term exposure to ultraviolet light will not only cause indoor items to fade and age, but may also pose a potential threat to human health. How to effectively resist the harm of ultraviolet rays has become an important issue that needs to be solved urgently in modern architecture.

UV absorber UV-326, as an efficient functional material, is gradually becoming a star product that improves the sun protection performance of building glass. It is like an invisible “sun protection clothing”, which can block harmful ultraviolet rays and allow visible light to pass smoothly, thereby maintaining a good lighting effect while protecting the indoor environment. This article will explore the characteristics of UV absorber UV-326 and its application in architectural glass from multiple angles, and let you understand the mystery behind this technology.

What is UV absorber UV-326?

Definition and Function

UV absorber UV-326 is a chemical substance specially used to absorb ultraviolet rays and belongs to a benzotriazole compound. Its main function is to capture ultraviolet energy through specific groups in the molecular structure and convert it into heat and release it, thereby avoiding direct damage to the material or the human body by ultraviolet light. Simply put, UV-326 is like an accurate “filter umbrella”, which can filter out harmful ultraviolet bands without affecting the transmission of other beneficial light.

Chemical structure and working principle

The chemical name of UV-326 is 2-(2′-hydroxy-5′-methylphenyl)benzotriazole, and its molecular formula is C15H13N3O. This compound has a highly stable chemical structure and can maintain excellent UV absorption capacity for a long time. Specifically, the working principle of UV-326 is as follows:

  1. Selective Absorption: UV-326 can preferentially absorb ultraviolet rays (including UVA and UVB) in wavelength range between 290nm and 400nm, which is a band with a great impact on human health and material aging.
  2. Energy Conversion: When ultraviolet rays are absorbed, UV-326 will convert these high-energy photons into low-energy thermal energy, and then disperse them into the environment in the form of heat, thereby achieving harmless treatment.
  3. Stability Maintenance: Even after multiple absorption and release cycles, UV-326 can still maintain high activity and is not easy to decompose or fail.

This unique mechanism makes UV-326 an ideal UVWire protective materials are widely used in plastics, coatings, textiles and architectural glass.

Detailed explanation of the product parameters of UV-326

To better understand the technical characteristics of UV-326, we can display its key parameters through the following table:

parameter name Unit Value Range Remarks
Appearance – White crystalline powder Easy to disperse, suitable for a variety of processing techniques
Melting point °C 148-152 High temperature stable, suitable for thermoplastic material processing
Solution g/100ml Insoluble in water, soluble in organic solvents Common solvents include methanol, etc.
Absorption wavelength nm 290-400 Cover the UVA and UVB bands
Large absorption efficiency % >98 Excellent performance in specified wavelength range
Photochemical stability – >1000 hours Verified by accelerated aging test
Toxicity LD50 (mg/kg) >5000 Complied with EU REACH regulations

It can be seen from the table that UV-326 not only has excellent ultraviolet absorption capacity, but also has good physical and chemical properties, which provides a solid guarantee for its performance in practical applications.

The application advantages of UV-326 in architectural glass

Introducing UV-326 into the field of architectural glass can not only significantly improve the sun protection performance of glass, but also bring a series of added value. Here are some of the main application advantages:

Improving sun protection effect

Although ordinary transparent glass in a building allows most visible light to enter the room, it also allows a large amount of ultraviolet rays to penetrate. researchIt has been shown that unprotected glass windows may cause more than 70% of ultraviolet rays to enter the room, which causes irreversible damage to indoor furniture, floors and other decorations. The special coated glass with UV-326 can reduce this proportion to less than 5%, greatly extending the service life of indoor items.

Improving living comfort

In addition to protecting property, reducing ultraviolet radiation can also improve people’s living experience. For example, long-term exposure to ultraviolet light can easily cause skin problems and even increase the risk of cancer. Therefore, installing sunscreen glass containing UV-326 ingredients in home or office is undoubtedly a strong care for the health of the family.

Energy saving and environmental protection benefits

It is worth noting that using UV-326 treated glass also helps reduce air conditioning energy consumption. This is because the ultraviolet rays themselves carry higher energy, and when they are blocked outside, the temperature fluctuations in the room will be more stable, thus reducing the workload of the refrigeration equipment. It is estimated that the use of such high-performance glass can reduce the power consumption of air conditioners in summer by about 15%-20%.

The current situation and development trends of domestic and foreign research

In recent years, as people pay more attention to environmental protection and sustainable development, the research and development of the ultraviolet absorber UV-326 has also made significant progress. Here are some directions worth paying attention to:

Exploration of new composite materials

Scientists are trying to combine UV-326 with other functional additives to develop more efficient composite materials. For example, some experiments have shown that modifying a thin UV-326 coating on the surface of nanotitanium dioxide (TiO2) can further enhance its photocatalytic activity while giving the material stronger UV shielding ability. This innovative approach is expected to be applied in high-end architectural exterior wall design in the future.

Research and development of intelligent responsive glass

Another exciting research area is the development of smart responsive glass. This type of glass can automatically adjust the light transmittance according to the external light intensity, thereby achieving dynamic sun protection function. At present, a team has proposed a conceptual solution based on UV-326 modified polymer film. This solution uses an external light source to trigger internal chemical reactions to achieve the purpose of real-time regulation.

Promotion of environmentally friendly products

With the rise of global green building trends, more and more companies are beginning to pay attention to the environmental performance of UV-326 production process. By optimizing the synthesis route and reducing by-product emissions, the new generation of environmentally friendly ultraviolet absorbers are gradually entering the market. These products not only meet strict international standards requirements, but also make positive contributions to promoting the sustainable development of the entire industry.

Conclusion

In short, UV absorber UV-326 is gradually becoming a building with its excellent performance and broad application prospects.An indispensable and important component of the glass field. Whether for individual users who pursue high-quality life or professionals who are committed to building low-carbon and environmentally friendly buildings, UV-326 provides a practical technical solution. Let us look forward to this technology continuing to break through itself in the future and creating a better living environment for mankind!

The importance of UV absorber UV-326 in home decoration materials

UV absorber UV-326: Invisible guardians in home decoration materials

Ultraviolet (UV) is everywhere in the environment we live in. Although it brings us the warmth of sunshine and the vitality of life, excessive ultraviolet radiation can have an unnegligible impact on our health and home environment. Imagine that the curtains, sofa covers and floors you carefully selected gradually fade, age and even crack under the long-term exposure of the sun. This is undoubtedly a repeated erosion of the beauty of the family. In this “war” with ultraviolet rays, the ultraviolet absorber UV-326 is like an invisible guardian, silently protecting the bright colors and long life of home decoration materials.

UV absorber UV-326 is a highly efficient light stabilizer, widely used in home decoration materials such as plastics, coatings, textiles, etc. Its main function is to absorb harmful ultraviolet energy and convert it into heat energy to release it, thereby preventing the material from degrading or discoloring due to ultraviolet rays. This magical chemical can not only extend the service life of home decoration materials, but also maintain its original beauty and texture.

Next, we will dive into how UV-326 plays a role in home decor materials and its importance in modern home design. From product parameters to practical applications, to the support of domestic and foreign literature, this article will reveal to you the big world behind this small compound. Let’s explore together how to make every inch of the space in your home full of lasting charm.

The mechanism of action of UV-326: protective shield for home decoration materials

To understand how UV-326 becomes the “protective shield” of home decoration materials, we need to first understand the specific destructive effects of ultraviolet rays on these materials. UV rays are mainly divided into three types: UVA, UVB and UVC. Among them, UVA and UVB are common in our daily lives and are also threatening to home decoration materials. When ultraviolet light hits the surface of the material, it stimulates energy inside the molecule, causing the molecular chain to break or reorganize, which in turn triggers a series of chemical reactions. For example, plastic products may experience brittleness and cracking; textiles may experience fading and fiber strength decrease; and coating materials may lose their luster and peel off. These problems not only affect the appearance of home decoration, but may also shorten their service life.

UV-326, as a highly efficient ultraviolet absorber, has the core function of being able to selectively absorb the energy of ultraviolet and quickly convert it into harmless thermal energy to release it. This process can be vividly likened to an “energy conversion station” that converts high-energy ultraviolet rays that could have caused the material to age into low-hazardous heat, thereby effectively protecting the material from damage. Specifically, UV-326 has the following key mechanisms of action:

  1. Absorb UV rays: UV-326 molecules contain specific aromatic groups.These groups have a strong absorption capacity to UV light. Once the ultraviolet ray is absorbed, the UV-326 will immediately enter the excited state.

  2. Energy conversion: UV-326 molecules in an excited state will not directly release high-energy radiation, but will dissipate energy in the form of heat through non-radiative transitions. This energy conversion process is both fast and safe, ensuring the stability of the material.

  3. Inhibit free radical generation: UV light usually triggers an oxidation reaction inside the material, producing a large number of free radicals. These free radicals further accelerate the aging process of the material. UV-326 absorbs ultraviolet rays, reducing the generation of free radicals, thereby delaying the aging rate of the material.

In order to more intuitively demonstrate the protective effect of UV-326 in different home decoration materials, we can refer to some experimental data. For example, in a study on polypropylene (PP) plastics, samples without UV-326 added decreased by about 40% after 500 hours of manual accelerated aging test, while samples with UV-326 added decreased by less than 10%. Similar results have also emerged in the fields of coatings and textiles, demonstrating the wide application value of UV-326 in a variety of materials.

To sum up, UV-326 provides a solid protective barrier for home decoration materials through its unique absorption and conversion mechanism. Whether it is plastics, coatings or textiles, UV-326 can significantly improve their weather resistance and service life, keeping the home environment fresh and bright at all times.

Its scientific design and rigorous manufacturing process enable it to perform well in various complex environments, bringing more reliable and lasting power to users.Experience it.

Analysis of practical application cases of UV-326

The application of UV-326 in home decoration materials has been widely verified and recognized. Below, we will gain an in-depth understanding of the performance of UV-326 in practical applications and its significant effects through several specific case studies.

Case 1: Aging protection of plastic products

In an aging test on polyethylene (PE) films, the researchers compared the PE films with UV-326 added to the control group without any UV absorber added. Both groups of samples were exposed to simulated natural light conditions for up to one year. The results showed that the PE film without UV-326 added showed significant yellowing and mechanical properties, and its tensile strength was reduced by about 35%. The PE film with UV-326 added not only retains the color better, but also reduces the tensile strength by less than 5%. This shows that UV-326 significantly improves the anti-aging performance of PE films and extends its service life.

Case 2: Improved weather resistance of coatings

In another study, UV-326 was used in building exterior paint for outdoor use. Through accelerated aging tests, the researchers compared the weather resistance differences between coatings containing UV-326 and ordinary coatings. It was found that after 1,000 hours of ultraviolet irradiation, the gloss retention rate of the UV-326 coating reached 85%, while that of the ordinary coating was only 40%. In addition, there was no obvious powdering or cracking on the surface of the UV-326-containing coating, showing excellent weather resistance.

Case 3: Color stability of textiles

UV-326’s application in textiles is equally impressive. A textile manufacturer has added UV-326 to its outdoor sunshade cloth to test its impact on color stability. The experimental results show that after three consecutive months of outdoor exposure to the sunscreen with UV-326, the color change ΔE value is only 3.2, which is far lower than the 5.0 specified in the industry standard. In contrast, the ΔE value of the sunshade cloth without UV-326 was as high as 8.5, which showed obvious fading. This fully demonstrates the outstanding role of UV-326 in maintaining the color stability of textiles.

Through these case studies, we can see that the practical application effect of UV-326 in home decoration materials is significant. It not only improves the material’s anti-aging properties, but also enhances its weather resistance and color stability, providing long-lasting protection for the home environment.

Support of domestic and foreign literature: Scientific research and application of UV-326 in home decoration materials

UV-326, as an efficient ultraviolet absorber, has attracted the attention of many scientific research institutions and scholars at home and abroad. By sorting out relevant literature, we can have a more comprehensive understanding of the science of UV-326Learning basis and its performance in practical applications.

Domestic research progress

In China, research on UV-326 mainly focuses on its protective effect on different materials. For example, a university study showed that UV-326 can significantly improve the weather resistance of polyvinyl chloride (PVC) floors. Through comparative experiments, the research team found that after 2,000 hours of artificial accelerated aging test, the surface gloss retention rate of PVC floors with UV-326 was as high as 88%, while the floors without UV-326 were only 56%. In addition, the study also pointed out that the addition of UV-326 has not negatively affected the hardness and wear resistance of PVC floors, which laid the foundation for its promotion in the high-end home improvement market.

Another research led by a well-known domestic chemical company focuses on the application of UV-326 in coatings. The research team developed a new environmentally friendly exterior wall coating, with UV-326 as one of the key components, significantly improving the UV resistance of the paint. Experimental data show that after two years of outdoor exposure to the sun, the color change ΔE value of this paint is only 4.1, far lower than the 7.5 of traditional paints. The study also emphasized that the addition of UV-326 not only enhances the weather resistance of the coating, but also reduces its VOC (volatile organic compound) emissions, which is in line with the current development trend of green and environmental protection.

International Research Trends

In foreign countries, the application research of UV-326 has also achieved fruitful results. A long-term follow-up survey by a research institution in the United States shows that the application effect of UV-326 in plastic products is particularly significant. The study selected a variety of common plastics (including PP, PE and PS), and added different concentrations of UV-326 for outdoor exposure tests. The results show that after three years of natural aging, the mechanical performance decline of plastic products with UV-326 was only about half of that of unadded groups. In addition, the study also found that the addition of UV-326 can effectively reduce the powdering phenomenon of plastic products, which is crucial to improving the visual effect of home decoration materials.

The research team from a European university focuses on the application of UV-326 in textiles. They developed a new functional textile fabric that successfully achieved effective shielding of UV rays by evenly dispersing UV-326 to the fiber surface. Experiments show that after six consecutive months of outdoor use, the ultraviolet transmittance of this fabric has always maintained below 5%, while ordinary fabrics are as high as more than 25%. More importantly, the addition of UV-326 has not affected the feel and breathability of the fabric, making it have broad application prospects in the field of home decoration.

Comprehensive Evaluation and Outlook

Based on domestic and foreign research results, we can draw the following conclusions: First, UV-326 performs excellently in improving the weather resistance and anti-aging properties of home decoration materials, and can effectively extend the service life of the materials; secondly, UV-326 has a wide range of applications, not only suitable for plastics and coatings, but also plays an important role in textiles and other fields. Later, with the increase of environmental awareness, UV-326 is becoming more and more popular in the market due to its low toxicity and good ecological compatibility.

In the future, with the continuous advancement of science and technology, the research and development direction of UV-326 may pay more attention to multifunctionality and intelligence. For example, the development of a new generation of composite ultraviolet absorbers combined with nanotechnology may bring a revolutionary improvement in the protective performance of home decoration materials. At the same time, how to further reduce the cost of UV-326 and improve the economic feasibility of its large-scale application will also become an important research topic.
