I. Overview of UV Ultraviolet Aging Chamber
By using fluorescent ultraviolet lamps similar to the UV spectrum in sunlight and combining them with temperature control devices, factors such as high temperature, high humidity, condensation, and dark rain cycles in the UV segment of sunlight that cause damage to materials, such as discoloration, reduced brightness and strength, cracking, peeling, powdering, and oxidation, are analodized. At the same time, through the synergistic effect between ultraviolet light and moisture, the single light resistance or single moisture resistance of the material is weakened or fails, thus being widely used in the evaluation of the material's weather resistance performance. The equipment provides the best sunlight UV simulation, has low usage and maintenance costs, is easy to use, adopts automatic control operation, has a high degree of automation in the test cycle, and has good light stability. It features a high reproducibility rate of test results.
