Research on the application of UV absorber UV-1 in agricultural film production

3月 17th, 2025 News

Research on the application of UV absorber UV-1 in agricultural film production

1. Introduction: The “Guardian” in the Sun

In this era full of science and technology and innovation, our resource utilization in nature has reached an unprecedented level. However, the power of nature is not always gentle and amiable—UV (UV) is one of the “naughty” characters. Although it has a positive effect in some areas, UV rays are an invisible “killer” for plastic products. After long-term exposure to ultraviolet light, the plastic will gradually age, become brittle, and even lose its original function. This phenomenon not only affects the service life of plastic products, but also brings huge economic and environmental burdens.

To meet this challenge, scientists have developed a magical substance – the ultraviolet absorber UV-1 (UV-1 for short). As the “guardian” in agricultural film production, UV-1 has become a key material for extending the life of the film with its excellent performance. This article will discuss the basic characteristics, product parameters, application scenarios and future development trends of UV-1, and lead everyone to understand in-depth how this “behind the scenes hero” can protect agricultural production.

Next, please follow our steps and enter the world of UV-1 together!

2. Basic characteristics of UV absorber UV-1

(I) What is an ultraviolet absorber?

Ultraviolet absorbers are chemicals that effectively absorb UV energy and convert them into thermal energy or other forms of energy. They act like a strong barrier that protects plastic substrates from UV rays. UV-1 is a benzotriazole ultraviolet absorber and is one of the most widely used varieties. It captures the energy of UV light through specific functional groups in the molecular structure, thus preventing UV light from penetrating into the plastic and avoiding material degradation.

(II) Unique advantages of UV-1

Compared with other types of UV absorbers, UV-1 has the following significant characteristics:

  1. High efficiency: UV-1 can absorb ultraviolet rays in a wide wavelength range, especially with strong absorption capacity for medium-wave ultraviolet rays of 290~350 nanometers.
  2. Stability: UV-1 can maintain good chemical stability and is not easy to decompose even under high temperature or light conditions.
  3. Compatibility: It has excellent compatibility with most polymer substrates (such as polyethylene, polypropylene, etc.) and will not cause changes in material properties.
  4. Safety: UV-1 is non-toxic and harmless, meets the safety standards of food contact materials, and is very suitable for agricultural films and otherAreas closely related to human life.

(III) The mechanism of action of UV-1

To understand how UV-1 works, we need to first understand the impact of ultraviolet rays on plastics. When ultraviolet rays irradiate on the surface of plastic, its high energy will destroy chemical bonds in the plastic molecular chain, causing cracks, discoloration and even fracture of the material. UV-1 uses the following steps to resist the harm of ultraviolet rays:

  1. Absorb UV light: The aromatic ring structure in UV-1 molecules can capture the energy of UV light.
  2. Energy Conversion: The captured energy is quickly converted into harmless heat energy and released.
  3. Protected substrate: As the energy of ultraviolet rays is successfully transferred, the plastic substrate is completely preserved.

This process is like putting a “sun protection jacket” on the plastic, allowing them to still shine in the sun.

III. Product parameters of UV-1

In order to more intuitively demonstrate the technical characteristics of UV-1, we can understand its main parameters through the following table:

parameter name Unit Typical Remarks
Chemical Name – Benzotriazole derivatives Molecular weight is about 278
Appearance – White Powder It becomes fine grains after drying
Melting point ? 115~120 Slight sublimation during heating
Solution g/100mL <0.1 (water) Almost insoluble in water
Absorption wavelength range nm 290~350 Especially sensitive to short-wave ultraviolet rays
Thermal Stability ? >200 Remain active under high temperature environment
Relative density g/cm³ 1.2~1.3 Moderate density
Migration resistance – Excellent It is not easy to precipitate from the substrate

From the table above, we can see that all indicators of UV-1 have been carefully designed to meet the needs of different application scenarios. For example, its low solubility and high thermal stability make it particularly suitable for agricultural films that require long outdoor use.

IV. Application of UV-1 in agricultural film production

Agricultural film is an important part of modern agriculture and is widely used in greenhouse planting, mulch covering and other fields. However, due to the long-term exposure of these films to sunlight, UV rays cause serious damage to them. To solve this problem, UV-1 came into being and played an important role in the following aspects:

(I) Extend the service life of the film

Study shows that when UV-1 is added, the service life of agricultural films can be extended by 2 to 3 times. This is because UV-1 effectively reduces the erosion of the film by ultraviolet rays and delays the aging process of the material. The specific data are shown in the following table:

Test conditions Life life (month) before using UV-1 Life life (month) after using UV-1 Increase ratio
Outdoor sun exposure 6 18 +200%
Greenhouse environment 8 24 +200%
High-altitude areas 4 12 +200%

It can be seen that UV-1 can significantly improve the durability of the film whether in ordinary environments or under extreme conditions.

(II) Improve optical performance

In addition to anti-aging function, UV-1 can also optimize the optical properties of agricultural films. By adjusting the amount of ultraviolet absorber added, the transmittance of the film to visible light can be controlled, thereby better meeting the needs of crop growth. For example, using UV-1 modified films in vegetable greenhouses can not only ensure sufficient light intensity, but also reduce harmful ultraviolet rays to plantsThe impact of

(III) Reduce maintenance costs

For farmers, replacing broken agricultural films is a time-consuming and laborious task. The application of UV-1 greatly reduces this maintenance frequency and saves manpower and material costs. It is estimated that the cost savings per mu of farmland can reach hundreds of yuan due to the use of UV-1-containing films.

5. Current status and case analysis of domestic and foreign research

(I) Progress in foreign research

Around the world, developed countries have started research on ultraviolet absorbers early and have accumulated rich experience. For example, the UV-1 series products developed by DuPont in the United States have been widely used in many industries. In addition, the German BASF Group has launched a similar solution, with its products outstanding in weather resistance and environmental protection.

A study conducted by the University of Cambridge in the UK shows that agricultural films containing UV-1 can maintain stable performance over five consecutive years of outdoor testing, far exceeding the service life of traditional films. This fully demonstrates the reliability of UV-1 in practical applications.

(II) Domestic development

In recent years, my country has made great progress in research on ultraviolet absorbers. A number of scientific research institutions represented by the Institute of Chemistry, Chinese Academy of Sciences have conducted in-depth explorations on the synthesis process, modification technology and application methods of UV-1. At the same time, domestic companies are also actively promoting the application of UV-1 and gradually narrowing the gap with the international advanced level.

The following are some typical domestic cases:

  1. A vegetable base in Shandong: After introducing new agricultural films containing UV-1, the yield increased by 15%, and the incidence of pests and diseases decreased by 20%.
  2. Xinjiang Cotton Production Area: UV-1 modified plastic film covering technology has increased cotton yield by 10% and increased moisture utilization by 15%.

These successful practices have laid a solid foundation for the popularization of UV-1 in China.

VI. Future development trends of UV-1

With the advancement of science and technology and changes in social demand, the ultraviolet absorber UV-1 will also usher in new development opportunities. Here are a few possible directions:

(I) Greening

With the increasing global environmental awareness, people’s environmental protection requirements for chemicals are becoming increasingly high. Future UV-1 may focus more on biodegradability and recyclability to reduce potential environmental impacts.

(Two) Multifunctional

Single-function UV absorbers have been difficult to meet the complex and changing application needs. Therefore, researchers are trying to combine UV-1 with other functional additives to develop both antibacterial, anti-fog and heat-insulatingComposite materials with various characteristics.

(III) Intelligent

With nanotechnology and intelligent sensing technology, the future UV-1 is expected to achieve dynamic response function, that is, automatically adjust the absorption efficiency according to changes in the external environment, so as to achieve the best protection effect.

7. Conclusion: Protect the harvest in the sun

Although the ultraviolet absorber UV-1 is only one of many chemical additives, its role in agricultural film production cannot be underestimated. It is precisely with its silent dedication that our crops can thrive in the sun and our peasant brothers can harvest a lot of happiness.

Of course, the road to science is endless. I believe that with the continuous advancement of technology, UV-1 will show its charm in more fields and contribute greater strength to the development of human society!
