1, Overview of UV aging chamber
Using fluorescent ultraviolet lamps similar to the UV spectrum in sunlight, combined with temperature control devices, to simulate factors such as high temperature, high humidity, condensation, and dark rain cycles that cause damage to materials such as discoloration, brightness, intensity decrease, cracking, peeling, pulverization, and oxidation in the UV segment. At the same time, the synergistic effect between ultraviolet light and moisture weakens or fails the material's single light resistance or single moisture resistance, As a result, it is widely used for evaluating the weather resistance performance of materials. The equipment provides the best sunlight UV simulation, has low maintenance costs, is easy to use, adopts control automatic operation, has a high degree of automation in the test cycle, good lighting stability, and high reproducibility of test results.
