UV Weathering Test Chamber

The UV weathering test chamber uses the fluorescent ultraviolet rays of UV lamps as the light source to simulate and strengthen the ultraviolet spectrum that has a significant impact on the deterioration of polymer materials, and appropriately combines temperature and humidity control to periodically produce condensation phenomena on the sample, so as to carry out simulation tests on accelerated aging of coatings, oil films, paints, resins, plastics, printing and packaging, adhesives, automobile industry, metals, electronics, medicine and other products. Through the test, the long-term aging effects of the outdoors can be quickly predicted, such as fading, discoloration, powdering, cracking, brittleness, strength loss, etc. It can help people make accurate correlation predictions about the aging resistance (weather resistance) of materials, and help the selection and formulation improvement of materials.

The company’s ultraviolet weathering test chamber refers to GB/T 16422.1-2006, “Test Method for Light Source Exposure in Plastics Laboratory”, GB/T14522-93 “Test Method for Artificial Climate Acceleration of Plastics, Coatings and Rubber Materials for Machinery Industry Products”, GB/T 18244-2000 “Test Method for Aging of Building Waterproof Materials”, GB/T1865-1997 “Colored Paints and Varnishes – Artificial Climate Aging and Artificial Radiation Exposure (Filtered Xenon Arc Radiation)” and other standards. It is comprehensively designed according to the material properties, shape and other factors of the customer’s sample.
