UV accelerated weathering test machine ,which as a kind of environment test chamber ,can be simulated by the harm the sun, rain and dew on materials caused, QUV use fluorescent ultraviolet (UV) lamps simulate the effect of sunlight, the proposed use of cold rain and dew moisture, was placed on the test material under a certain temperature alternating light and moisture cycle program for testing, QUV with a few days or weeks of testing, we can reproduce the hazards outdoors for several months to several years appeared.and mainly used for UV coating ink, paint, resins, plastics, printing and packaging, aluminum, cement, automobile motorcycle industry, cosmetics, metal, electronics, electroplating, medicine, etc.
1. Simulate the sun, rain spray and condensation resulting damage to test the materials by exposure to sunlight with moisture and temperature.
2. To get the results of damage after several days or weeks which is equal to expose to outside for a few months. The damages include fading, discoloration, brightness down, powder, crack, blur, brittle, strength decreases and oxidation.
3. Provide reference with testing data for improvement of existing materials, or to assess the impact of changes in product durability and other aspects.
