The Difference Between UVA-340,UVB-313 and UVA-351 in UV Test Chamber
June 24, 2021
Polymer UV aging test is a common aging test for rubber and plastic products. In addition to UV aging and sunlight aging, there are also temperature aging and loading aging. UV aging test is also called ultraviolet aging test, which uses ultraviolet light that resembles sunlight to perform aging light test on materials.
UV refers to the ultraviolet light in sunlight. Because its light energy is equivalent to the bond energy of the polymer chemical bond, it can cause the break of the polymer compound chain, which is the main cause of the degradation and degradation of polymer materials.
The main key test component used for UV aging test is UV lamp tube. Generally, UV lamp tube can be divided into UVA and UVB.
|●UVB-313 tube: The short-wave ultraviolet light emitted by the UVB-313 tube is stronger than the sun's ultraviolet rays that generally illuminate the surface of the earth, which can accelerate the aging of the material to the greatest extent. However, the lamp may cause unrealistic damage to some materials. UVB-313 tubes are mainly used for quality control and research and development, or for testing materials with strong weather resistance.|
|●UVA-340 lamp tube: UVA-340 lamp tube can mimic the short-wave ultraviolet light in sunlight very well, that is, the wavelength range from 365 nanometers to the cut-off point of sunlight 295 nanometers.|
|●UVA-351 tube: imitating the sunlight and ultraviolet light passing through the window glass, it is the most effective for testing the aging of indoor materials.|
The purpose of different types of UV lamps(uv weathering test equipment)
●UVA-340: It resembles the ultraviolet part of sunlight, mainly used for photo-aging testing of outdoor products.
●UVB-313: It is widely used in fast and economical testing of durable materials, which will accelerate the aging of materials.
●UVA-351: Used to simulate the ultraviolet part of sunlight passing through window glass, mainly used indoors.
