The ultraviolet aging test chamber can simulate the water exposure aging test of non-metallic materials such as coatings caused by sunlight, rain and dew. The damage caused by materials is due to the ultraviolet ray in the sunlight is the main factor causing the oxidative degradation of polymers, and the moisture is an important destructive factor to accelerate aging, so this device has the characteristics of quickly and easily simulating outdoor exposure aging,
The material to be tested is placed in a cycling procedure of alternating light and moisture at a certain temperature. UV can reproduce the outdoor hazards that occur for months to years after several days or weeks of testing. The hazard types include fading, discoloration, loss of gloss, pulverization, cracks, turbidity, blistering, embrittlement, strength degradation and oxidation. It has practical value for testing the relative weathering resistance of different test pieces.
