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.
