The ultraviolet tube was selected as the light source, and the comprehensive conditions such as outdoor ultraviolet light, damp heat condensation and rainfall were simulated by changing and controlling the irradiance, blackboard temperature, condensation, rain, etc., and the aging test was carried out on the sample. The accelerated aging rate of ultraviolet light is higher than that of other light sources, which is suitable for various ultraviolet aging tests and rapid screening of specific materials.
· l Commonly used ultraviolet lamps are mainly UVA340 and UVB313
· l UVA-340 is the best choice for simulating the sun's ultraviolet rays, as it is an excellent simulation of the sunlight spectrum in the critical short-wavelength range, i.e., the wavelength range of 295-360nm, and UVA-340 produces only the UV wavelength spectrum found in sunlight.
· l The UVB-313 is used for maximum acceleration and can provide results very quickly. It uses short-wavelength UV rays that are more intense than the UV waves typically found on Earth today. Although these UV light, which is much shorter than the natural wavelength, can speed up the test to the greatest extent, it can also cause inconsistencies and actual degradation damage to some materials.
