The role of UV absorber UV-326 in electric vehicle charging facilities

UV Absorbent UV-326: Invisible Guardian of Electric Vehicle Charging Facilities

In today’s era of rapid technological development, electric vehicles (EVs) have developed from a conceptual idea to the core force of the global green energy transformation. With the popularity of electric vehicles, the importance of its supporting infrastructure – charging facilities, is becoming increasingly prominent. However, behind these seemingly simple charging piles, there are many little-known technical details hidden, and the UV absorber UV-326 is one of them.

UV-326 is a high-performance ultraviolet absorber, widely used in plastics, coatings, adhesives and other fields. It effectively protects the material from damage from UV radiation by absorbing the energy of UV and converting it into harmless thermal energy. This chemical is especially important for electric vehicle charging facilities, which are often exposed to outdoor environments and are subject to prolonged direct sunlight and severe weather. If the casing or internal components of the charging device are damaged by UV aging, it will not only shorten the life of the device, but may also cause safety hazards.

This article will deeply explore the key role of the ultraviolet absorber UV-326 in electric vehicle charging facilities, from product parameters to practical applications, and then to the current research status at home and abroad, and analyze the unique charm of this “behind the scenes” in a comprehensive manner. Let’s uncover the mystery of the UV-326 and see how it safeguards the future of electric vehicles.

Basic features and functions of UV-326

Chemical structure and physical properties

UV absorber UV-326, chemically named 2-(2′-hydroxy-5′-methylphenyl)benzotriazole, is a highly efficient and stable UV protective agent. Its molecular formula is C15H11NO2 and its molecular weight is 243.26 g/mol. UV-326 is known for its unique benzotriazole ring structure, which imparts its excellent UV absorption properties. Specifically, UV-326 can effectively absorb ultraviolet rays in the wavelength range between 280 and 380 nanometers and convert them into harmless thermal energy to release them, thereby preventing the material from degrading or discoloring due to ultraviolet irradiation.

In terms of physical properties, UV-326 is manifested as a white crystalline powder with a melting point of about 115°C, with good heat resistance and stability. It is not volatile and exhibits good solubility in most organic solvents, making it ideal for use in a variety of plastic and coating systems. In addition, UV-326 also has high extraction resistance, which means it is not easily extracted from the composite material by water or other media, so it can maintain its protective effect for a long time.

Absorption mechanism and efficiency

The mechanism of action of UV-326 can be divided into two main stages: first, the absorption stage of ultraviolet rays, and second, the conversion stage of energy. When UV light is shiningWhen shot onto the surface of a material containing UV-326, the benzotriazole ring in the UV-326 molecule quickly captures the energy of the ultraviolet photons. This energy is then transferred to the electron structure of the molecule, causing it to enter an excited state.

Once entering the excited state, UV-326 releases excess energy in the form of heat through non-radiative transitions, rather than consuming energy through destructive chemical reactions. This method ensures that the molecular structure of the material is not damaged, thereby extending the service life of the material. Studies have shown that UV-326’s absorption efficiency of ultraviolet rays is as high as more than 95%, especially in the 300 to 360 nanometer band.

Comparison with other UV absorbers

There are many types of ultraviolet absorbers on the market, including benzophenones, benzoate and triazine. Each type has its specific application areas and advantages. However, UV-326 stands out among a wide range of applications due to its excellent overall performance.

Type Pros Disadvantages
Benzophenone Efficient absorption of short-wave ultraviolet rays Easy to yellow, poor weather resistance
Benzoate Good weather resistance and stability Limited absorption of long-wave ultraviolet rays
Triazines Broad spectrum absorption, suitable for high transparency applications High cost, easy to migrate
UV-326 (benzotriazoles) Good comprehensive performance, good stability and weather resistance Relatively moderate cost

From the above table, it can be seen that although benzophenone absorbers have excellent performance in short-wave ultraviolet absorption, they are prone to yellowing of the material; benzoate esters have certain advantages in weather resistance, but they lack the protection ability of long-wave ultraviolet rays; although triazines provide broad-spectrum absorption, their high cost and mobility limit their wide application. In contrast, UV-326 shows balanced advantages in all aspects and is ideal for many industrial applications.

To sum up, UV-326 has become a key component in protecting materials from ultraviolet rays due to its excellent chemical structure, efficient absorption mechanism and obvious advantages over other types of absorbents. In the following sections, we will discuss in detail the specific application and importance of UV-326 in electric vehicle charging facilities.

UV-326 in electric vehicle charging facilitiesApplications in

Protection of charging pile shell material

Electric vehicle charging facilities, especially charging piles, are often exposed to outdoor environments and are affected by various natural factors such as direct sunlight, rainwater erosion and temperature changes. UV radiation is one of the destructive factors, which can cause the aging and deterioration of plastic shell materials. Specifically, ultraviolet rays can break polymer chains, reduce the mechanical strength and toughness of the material, and ultimately lead to cracking and deformation.

UV-326, as an efficient ultraviolet absorber, can significantly delay this aging process. By adding UV-326 to the plastic formula of the charging pile housing, UV rays can be absorbed effectively, preventing them from penetrating into the inside of the material and causing damage. Experimental data show that the UV-326-treated polycarbonate (PC) material has only dropped by 5% under continuous ultraviolet irradiation for 1,000 hours, while the untreated material has dropped by nearly 40%. This fully demonstrates the excellent effect of UV-326 in improving the durability of charging pile shells.

Protection of internal electronic components

In addition to the visible part outside, the electronic components inside the charging pile also need to be properly protected. These components are usually encapsulated in plastic or resin to isolate the influence of the outside environment. However, even in a relatively closed space, ultraviolet rays may enter through tiny gaps or light-transmitting windows, gradually eroding the packaging material, thereby affecting the normal operation of electronic components.

UV-326 also plays an important role in this case. It can be added to the encapsulation resin to form a layer of invisible protective barrier that prevents UV rays from damage to sensitive electronic components. For example, in a study on the charging pile control module, it was found that after packaging using epoxy resin containing UV-326, the module maintained good electrical performance after two years of operation in simulated outdoor environments, while the control group without UV-326 showed a significant performance decline.

Improve the durability and safety of the overall equipment

Through the above two aspects of application, UV-326 not only extends the service life of the charging pile, but also improves the safety and reliability of the entire system. For users, this means less maintenance requirements and lower operating costs. At the same time, the risk of failure caused by material aging is reduced, and the safety of the charging process is indirectly improved.

In short, the application of UV-326 in electric vehicle charging facilities is not limited to one aspect, but runs through all aspects of equipment design and manufacturing. Its addition allows these high-tech equipment to operate stably and reliably in complex and changeable outdoor environments, providing a solid guarantee for promoting the sustainable development of the electric vehicle industry.

The research team from the Department of Materials Science and Engineering of Tsinghua University conducted in-depth exploration in the field of modification and application of UV-326. They proposed a UV-326 dispersion method based on nanotechnology, which greatly improved its uniform distribution in polymer materials, thereby improving the protective effect.

At the same time, Shanghai Jiaotong University cooperated with many well-known companies to carry out a study on the application of UV-326 in the full life cycle management of outdoor charging piles. The research results show that by rationally selecting UV-326 and combining other protective measures, the service life of charging piles can be extended by at least 30%. This achievement provides important technical support for the standardization construction and large-scale promotion of domestic charging facilities.

Technical Innovation and Future Development

Whether internationally or domestically, the research direction of UV-326 is developing towards a more refined and multifunctional direction. Future innovations may include the following aspects:

  1. Intelligent regulation: By introducing intelligent responsive materials, UV-326 can automatically adjust its absorption efficiency according to environmental conditions.
  2. Environmentally friendly development: Research more environmentally friendly production processes to reduce the impact on the environment during UV-326 production process.
  3. Multifunctional composite: combine UV-326 with other functional additives to develop UV-326, antibacterial,Composite materials with multiple characteristics such as fire resistance.

In general, with the continuous advancement of science and technology and the continuous growth of market demand, the application prospects of UV-326 in the field of electric vehicle charging facilities will be broader. These research results not only promote the development of industry technology, but also lay a solid foundation for achieving the goal of green travel.

Through these detailed data, we can see why the UV-326 is an ideal choice for protecting charging facilities from UV damage.

Analysis of the application of UV-326 in actual cases

In order to more intuitively understand the practical application effect of the UV absorber UV-326 in electric vehicle charging facilities, we selected several typical cases for in-depth analysis. These cases not only showcase the powerful capabilities of UV-326, but also reveal its protective effect on charging facilities under different environments and conditions.

Case 1: Weather resistance challenge in coastal urban charging stations

A large charging station located on the southeast coast of China, faces the dual challenges of strong ultraviolet radiation and high humidity. This charging station hosts hundreds of electric cars every day, and the shell material of its charging equipment is mainly polycarbonate (PC). Without the use of UV-326, the device shell showed obvious fading and cracking in less than a year.

To solve this problem, the technician decided to add an appropriate amount of UV-326 to the PC material. After redesign and production, a new generation of charging equipment is put into operation. After two years of field testing, the shells of this batch of equipment not only retained their original color, but also did not show any cracks or deformation. Data shows that UV-326 successfully improves the equipment’s weather resistance by more than 50%.

Case 2: High temperature protection in desert areas

In an electric vehicle charging network construction project in the Middle East, engineers encountered another extreme environment – high temperature and strong ultraviolet radiation. The temperature here often exceeds 50 degrees Celsius in summer, and the strong ultraviolet rays accelerate the aging of the equipment.

To cope with this harsh environment, the R&D team chose special composite materials containing UV-326 to manufacture the housing and internal components of the charging device. Through comparative experiments, it was found that after three consecutive years of high temperature exposure, the mechanical performance decline was only half that of the unused UV-326 equipment. This shows that UV-326 also has significant protective effects in extreme high temperature environments.

Case 3: Multifunctional protection in urban centers

In the center of a large European city, a modern charging station adopts advanced intelligent management system and is equipped with a large number of electronic components. These components need to maintain stable operation in complex electromagnetic environments, while also resisting ultraviolet rays and other environmental factors.

To this end, the design team selected epoxy resin containing UV-326 to package electronic components. After more than a year of actual operation, all electronic components have maintained good working conditions and there is no performance degradation or failure caused by ultraviolet rays. This proves that UV-326 can not only protect the physical structure, but also effectively maintain the long-term stability of electronic systems.

Through these practical cases, we can clearly see the protective effect of UV-326 on electric vehicle charging facilities under various environments and conditions. Whether in the high humidity environment of coastal cities, in the extreme high temperatures of desert areas, or in the complex electromagnetic fields in the center of the city, UV-326 can show its excellent protection and adaptability. These successful cases not only verifies the effectiveness of UV-326, but also provide valuable practical experience for future applications.

The market prospects and future prospects of UV-326

With the continuous increase in global awareness of environmental protection and the rapid development of the electric vehicle industry, the market demand for UV absorber UV-326 is showing a rapid growth trend. It is expected that this market will maintain an average annual growth rate of more than 10% in the next decade, especially in the field of electric vehicle charging facilities, where the application prospects of UV-326 are particularly broad.

Market Trend Analysis

At present, the global UV absorber market is mainly dominated by North America, Europe and Asia-Pacific. Among them, the Asia-Pacific region has become one of the fast-growing markets due to its huge population base and rapidly developing economy. Especially in emerging economies like China and India, the strong government support for new energy vehicles has promoted the vigorous development of related infrastructure construction, thus significantly increasing the demand for UV-326.

Future development direction

Looking forward, the technological innovation of UV-326 will focus on the following aspects:

UV Absorbent UV-326: Invisible Guardian in Water-Based Coatings

In the world of paint, there is a mysterious existence, which is like an invisible guard, silently protecting the coating from ultraviolet rays. This “hero” is the ultraviolet absorber UV-326 (hereinafter referred to as UV-326), an important additive widely used in environmentally friendly water-based coatings. With the increasing global emphasis on environmental protection and sustainable development, water-based coatings are favored for their low volatile organic compounds (VOC) emissions. However, water-based coatings often appear fragile when exposed to ultraviolet rays, and are prone to problems such as aging, discoloration and even cracking. It is in this context that the UV-326 stands out with its excellent performance and becomes the key to solving this problem.

This article will conduct in-depth discussions on the application cases of UV-326 in environmentally friendly water-based coatings, from its basic principles to specific practices, from product parameters to domestic and foreign research progress, and comprehensively analyze how this magical substance injects new vitality into the coating industry. Through easy-to-understand language and rich examples, we will unveil the mystery of UV-326 and understand why it can become the “guardian” of the paint world. In addition, the article will present key data in a table form and cite a large number of domestic and foreign literature to support the views, striving to be rich in content and clear in organization. Let us embark on this exploration journey together!


Basic Characteristics and Mechanism of UV-326

What is an ultraviolet absorber?

Ultraviolet absorbers are a class of chemicals that can effectively absorb UV energy and convert it into harmless thermal energy. They are widely used in plastics, rubbers, coatings and other polymer materials to delay or prevent aging caused by ultraviolet radiation. Simply put, the ultraviolet absorber is like a “sun umbrella” that blocks the material from the strong ultraviolet attacks from the sun.

UV-326 is a typical benzophenone ultraviolet absorber with a chemical name of 2-(2′-hydroxy-5′-methylphenyl)benzotriazole. As one of the high-performance light stabilizers, UV-326 has the following significant features:

  1. Efficient absorption of ultraviolet rays: UV-326 can efficiently absorb ultraviolet rays in the wavelength range of 280-315nm, which is a band where ultraviolet rays severely damage polymer materials.
  2. Excellent heat resistance: Even under high temperature conditions, UV-326 can maintain stable performance without decomposing or failing.
  3. Good compatibility: UV-326 is compatible with most solvent and resin systems and is easily dispersed in aqueous coatings.
  4. Low toxicity: As an environmentally friendly additive, UV-326 has a very small impact on the human body and the environment and complies with strict international standards.

Mechanism of action of UV-326

The reason why UV-326 can effectively protect water-based coatings is mainly due to its unique molecular structure and mechanism of action. Here is a detailed description of how it works:

  1. Ultraviolet capture: When ultraviolet rays hit the surface coated with UV-326, UV-326 molecules preferentially absorb the energy of the ultraviolet ray.
  2. Energy conversion: The absorbed ultraviolet energy is quickly converted into harmless heat energy and released, thereby avoiding the damage to the internal structure of the coating by ultraviolet rays.
  3. Recycling: UV-326 will not undergo permanent changes in this process, and can repeatedly absorb and convert ultraviolet energy, so it has long-term protection capabilities.

This efficient protection mechanism makes UV-326 an indispensable component in water-based coatings, especially in outdoor environments.


Detailed explanation of the product parameters of UV-326

To understand the performance of UV-326 more intuitively, we can list its main product parameters through the following table:

parameter name Specific value or range Remarks
Chemical Name 2-(2′-hydroxy-5′-methylphenyl)benzotriazole
Molecular formula C15H13NO2
Molecular Weight 243.27 g/mol
Appearance White to light yellow crystalline powder Easy soluble in alcohols and ketone solvents
Melting point 129-132? Good heat resistance
Solution Insoluble in water, soluble in organic solvents In aqueous systems, dispersion is required with the help of emulsifiers
Absorption wavelength 280-315 nm Mainly targets UV segment B
Major absorption peak 308 nm
Antioxidation stability High Even if exposed to air for a long time, it is not easy to oxidize
Toxicity Low Compare EU REACH regulations and FDA requirements

The above parameters show that UV-326 not only performs excellent in technical performance, but also fully meets the needs of modern environmentally friendly coatings in terms of safety.


The application advantages of UV-326 in environmentally friendly water-based coatings

As people’s concerns about health and the environment continue to increase, traditional solvent-based coatings have gradually been eliminated, replaced by more environmentally friendly water-based coatings. However, water-based coatings face many challenges during use, and the prominent problem is the aging of coatings caused by ultraviolet rays. UV-326 has successfully solved this problem with its unique advantages, which is reflected in the following aspects:

1. Improve coating weather resistance

Aqueous coatings are usually made of water as diluent, and although they are environmentally friendly, their weather resistance is relatively poor. Long-term exposure of ultraviolet rays will cause the polymer chain in the coating to break, which will lead to pulverization and cracking. UV-326 absorbs ultraviolet energy and converts it into heat energy, effectively reducing the direct damage to the coating by ultraviolet rays, thereby significantly improving the coating’s weather resistance.

2. Improve coating color stability

Ultraviolet rays not only destroy the physical structure of the coating, but also cause the pigment to fade or discolor, affecting the aesthetics of the coating. The addition of UV-326 can effectively prevent this problem and ensure that the coating can still maintain a bright color when exposed to sunlight for a long time.

3. Strengthen coating adhesion

Ultraviolet radiation can also weaken the adhesion between the coating and the substrate, especially in materials such as metal or wood. UV-326 indirectly enhances the bonding force between the coating and the substrate by reducing the damage to the internal structure of the coating by ultraviolet rays, improving overall performance.

4. Meet environmental protection requirements

UV-326 itself is a chemical with low toxicity and low volatile properties, and fully meets the standards of modern environmentally friendly coatings. Its use not only improves the performance of the paint, but also reduces the potential threat to the environment and human health.


Analysis of domestic and foreign research progress and application case

Domestic researchCurrent situation

In recent years, domestic scientific research institutions and enterprises have conducted in-depth research on the application of UV-326 in water-based coatings. For example, a well-known coating company found through experiments that after adding 1% UV-326 to aqueous acrylic coatings, the weather resistance of the coating was increased by nearly 50%, and the color stability was significantly improved. Another study shows that UV-326 is better when used in conjunction with other additives such as antioxidants and light stabilizers, which provides new ideas for the development of multifunctional composite coatings.

International Research Trends

In foreign countries, the application of UV-326 has also attracted widespread attention. A US research team found through comparative tests of a variety of ultraviolet absorbers that UV-326 performs excellently in aqueous polyurethane coatings, especially in long-term stability under extreme climate conditions. A German chemical company has developed a new water-based coating formula, in which the dosage of UV-326 has been accurately optimized to achieve an excellent balance between cost and performance.

Application Case Analysis

Case 1: Outdoor Building Paint

In a large-scale construction project, the construction party chose water-based exterior wall coating containing UV-326. After three years of actual use, the coating has not shown obvious powdering or fading, which fully proves the effectiveness of UV-326.

Case 2: Automobile Industry

In the field of automobile manufacturing, UV-326 is widely used in body paint. A brand of automaker reported that after using water-based coatings containing UV-326, the appearance of the vehicle remains bright and new in sunny environments, and customer satisfaction has been greatly improved.

Case 3: Wooden Coating

For wooden furniture, the choice of ultraviolet absorber is particularly important. By introducing UV-326, a high-end furniture brand has successfully solved the problem that traditional water-based wood paints are prone to yellowing when used outdoors, further consolidating its market position.


Conclusion: Future Outlook of UV-326

To sum up, the ultraviolet absorber UV-326 has a broad application prospect in environmentally friendly water-based coatings. It not only solves the shortcomings of traditional water-based coatings in terms of weather resistance and color stability, but also provides strong support for the green transformation of the coating industry. With the continuous advancement of technology, I believe that UV-326 will show its unique charm in more fields and become an important force in promoting the sustainable development of the coatings industry.

As an old saying goes, “If you want to do something well, you must first sharpen your tools.” UV-326 is undoubtedly the weapon in the field of paint, adding more colors and guarantees to our lives.

Application effect of UV absorber UV-P in high-end leather products

UV absorber UV-P: Invisible Guardian for High-end Leather Products

Introduction

We often enjoy warmth and vitality on sunny days, but ultraviolet (UV) quietly causes harm to our daily necessities. For high-end leather products that pursue quality and durability, UV erosion is particularly fatal. Imagine your beloved leather handbags, luxurious leather sofas or classic leather shoes gradually fade, age and even crack under the long-term exposure of the sun. Such a scene is undoubtedly heartbreaking.

To protect these precious objects, scientists have developed a magical protective tool – the ultraviolet absorber UV-P. It is like an invisible guard, silently protecting leather products from ultraviolet rays. This article will deeply explore the application effect of the ultraviolet absorber UV-P in high-end leather products, and show the charm of this technological treasure in all aspects from its basic principles to specific applications and then to market prospects.

What is UV absorber UV-P?

UV absorber UV-P is a chemical substance specially designed to resist UV damage. Its main function is to absorb the energy of ultraviolet rays and convert them into harmless heat energy to release them, thereby preventing the damage to the material by ultraviolet rays. Such absorbents are often added to coatings, plastics, and leather treatments to enhance the weather resistance and service life of the product.

The chemical structure of UV-P allows it to efficiently absorb ultraviolet rays in the wavelength range of 290-400 nanometers, which is the destructive part of most organic materials. In this way, UV-P not only extends the service life of the product, but also maintains the freshness of its appearance and the brightness of its colors.

The working principle of UV absorber UV-P

To understand how UV-P works, we need to first understand the basic properties of UV rays and their impact on the material. UV rays are divided into three types: UVA, UVB and UVC, among which UVA and UVB are the main components that penetrate the atmosphere and reach the earth’s surface. When these ultraviolet rays irradiate on organic materials such as leather, they will trigger a series of photochemical reactions, causing the material’s molecular chain to break, which will eventually manifest as color fading and physical properties degraded.

UV-P uses the following mechanism to combat the harm of ultraviolet rays:

  1. Absorbing Energy: UV-P molecules contain specific functional groups that can capture and absorb energy from ultraviolet rays.
  2. Energy conversion: The absorbed energy is quickly converted into harmless heat energy or vibrational forms to be emitted, avoiding harmful photochemical reactions.
  3. Stability: UV-P itself has good photostability and thermal stability, ensure that it continues to be effective during long-term use.

Through these steps, UV-P effectively protects leather products from ultraviolet rays and maintains their original beauty and functionality.

Detailed explanation of product parameters of UV absorber UV-P

Understanding the specific parameters of the UV absorber UV-P is crucial to assess its application effect in high-end leather products. The following are some key product parameters and technical indicators of UV-P. We will display them in detail in the form of a table to facilitate readers to better understand and compare.

Through these detailed parameter analysis, we can more clearly understand why UV-P has become an indispensable part of the modern leather industry.

The application effect of UV absorber UV-P in high-end leather products

Specific application cases of UV-P in different leather products

Genuine Leather Handbag

The genuine leather handbags are popular for their noble and elegant design and excellent materials. However, the damage caused by ultraviolet rays cannot be ignored. The application of UV-P significantly improves the anti-aging ability of the handbag. For example, a well-known brand added UV-P to its new leather handbag. After a year of outdoor testing, it was found that its color retention rate was about 30% higher than that of handbags without UV-P, and the softness of the hand feel was almost unchanged.

Furniture Leather

Furniture leather such as sofas and headboards are prone to fading and cracking due to long-term exposure to indoor light and occasional direct sunlight. UV-P plays a crucial role here. An Italian furniture manufacturer has adopted UV-P technology in its high-end leather range, and the results show that these leathers can maintain their color and elasticity for at least five years even under strong sunlight.

Leather Shoes

Leather shoes, especially white or light-colored styles, are very susceptible to ultraviolet rays and turn yellow or loseluster. The application of UV-P has effectively solved this problem. A German shoe brand has successfully launched several “never faded” white leather shoes by adding UV-P to the upper coating, which are deeply loved by consumers.

Enhance the durability and appearance of leather products

UV-P not only significantly improves the durability of leather products, but also helps maintain the freshness of its appearance. By absorbing ultraviolet rays, UV-P reduces the occurrence of photodegradation reactions, thereby delaying the aging process of leather. This means that leather products can remain in their original state for a long time, whether in color or texture.
