Artificially created to reproduce ultraviolet light
The ultraviolet weather resistance test box adopts fluorescent ultraviolet lamp as the light source. By simulating the ultraviolet radiation and condensation in natural sunlight, the material is subjected to an accelerated weather resistance test to obtain the result of the weather resistance of the material. It can simulate the environmental conditions of ultraviolet, rain, high temperature, high humidity, condensation, darkness and other environmental conditions in the natural climate. By reproducing these conditions, they are combined into a cycle and let it automatically complete the number of cycles.
The reason why the UV weather resistance test box uses UV lamps is that they are more stable than other lamps, and can better reproduce the test results. Using fluorescent UV lamps to simulate the effects of sunlight on physical properties, such as brightness reduction, cracking, and flaking, is the best method. Let's take a look at the comparison between the spectrum of the two lamps and the spectrum of sunlight.
