Application scope: This test chamber is suitable for testing the degree of aging of materials and products under changes in climate conditions such as sunlight, humidity, temperature, and condensation. Obtain discoloration, fading, and other conditions in a short period of time.
Equipment Overview: It simulates the damage caused by sunlight, rainwater, and dew, and tests the material by exposing it to the alternating cycle of light and moisture under controlled high temperature. It uses ultraviolet lamps to simulate the radiation of sunlight, and uses condensed water and water spray to simulate dew and rainwater.
The equipment can withstand laboratory damage such as fading, color changes, loss of luster, powdering, cracking, cracking, wrinkling, blistering, embrittlement, reduced strength, and oxidation in environments that take months or even years to occur outdoors, in just a few days or weeks. The test results can be used to select new materials, improve existing materials, or evaluate changes in material formulations.
