Explain the testing process of the UV aging test box

The ultraviolet radiation generated by the internal simulation of the ultraviolet aging test box is strong enough to irradiate the surface of the Earth, which can greatly accelerate material aging. And it can simulate the damage effects of materials in outdoor humid environments that are more realistic. Simulate the condensation cycle process and generate steam by heating the water tank at the bottom of the equipment.

The UV aging test box is widely used in aging tests in industries such as coatings, rubber fading, and cracking, providing a large amount of practical data for product improvement and shortening the product development and design process. Due to the prolonged exposure of materials to moisture outdoors, a typical circulating condensation system requires at least 4 hours of testing time. The condensate obtained in this way is a pure distilled water with stable properties. This water can improve the reproducibility of test results, eliminate pollution from water sediment, and simplify the installation and operation of test equipment.

Compared to water spray, immersion, and other high humidity environments, the UV aging test box can undergo long-term condensation cycles under heating conditions, which will more effectively reproduce the phenomenon of material damage in humid environments. At higher temperatures, the condensation process greatly accelerates the rate of material damage due to moisture.

The reason why UV lamps are used in the UV aging test box is because compared to other lamp tubes, UV lamps have more stability and better reproducibility. Simulating the impact of sunlight on physical properties, such as brightness reduction, cracking, peeling, etc., using ultraviolet lamps is a good method. Because outdoor exposure to sunlight can last up to 12 hours per day, UV accelerated moisture resistance testing devices typically last for several hours. It is recommended that each condensation cycle last at least 4 hours. Please note that UV exposure and condensation are carried out separately.
