紫外线老化试验箱

UV aging test chamber

1、 Overview

This experimental equipment simulates damage caused by solar ultraviolet light and conducts weather resistance tests on the tested material by exposing it to controlled high temperature light. It uses ultraviolet light tubes to simulate the radiation effect of sunlight, and simulates dew and rainwater through condensation and water spraying. In just a few days or weeks, ultraviolet radiation equipment can undergo damage that only takes months or even years to occur outdoors, including fading, color change, loss of luster, pulverization, cracking, wrinkling, foaming, embrittlement, strength reduction, oxidation, etc, The test results can be used to select new materials, improve existing materials, or evaluate changes in material formulations.
