The UV aging test chamber uses a fluorescent UV lamp that is excellent in analogy to the ultraviolet spectrum of sunlight, comb
-ined with temperature control, humidity supply and other devices to analogize the damage to materials such as discoloration,
brightness, strength decline, cracking, peeling, pulverization, and oxidation. Fluorescent ultraviolet lamps that are best analog
-ous to the ultraviolet spectrum of sunlight, through the synergistic efect between ultraviolet light and moisture, make the mat
-erial's single light resistance or single humidity resistance weaken or fail, and are widely used in the evaluation of the weather
resistance of materials.
