​The main purpose:

The ultraviolet aging test box can simulate the harm caused by sunlight. The testing machine uses fluorescent ultraviolet lamps to simulate the effect of sunlight, and the tested materials are placed in the light at a certain temperature for testing. It takes a few days or weeks to reproduce the hazards that have occurred outdoors for months or years. The hazard types include: fading, discoloration, loss of gloss, pinking, cracking, peeling, turbidity, bubbles, embrittlement, strength reduction, decay, and oxidation. Widely used in coatings, inks, paints, resins, plastics, printing and packaging, adhesives, automobile and motorcycle industries, cosmetics, metals, electronics, electroplating, medicine and other industries.
