UV Accelerated Aging Testing Machine In The Evaluation Of The Material's Weather Resistance

DX8494 UV Accelerated Aging Testing Machine

1. Overview of UV ultraviolet aging box

The fluorescent ultraviolet lamp with a spectrum similar to the UV segment in the sunlight, combined with the temperature control device to compare the high temperature, high humidity, condensation, dark rain cycle and other factors that cause damage to the material such as discoloration, brightness, intensity reduction, cracking, peeling, pulverization, oxidation, etc., at the same time, through the synergistic effect between ultraviolet light and moisture, the single lightfastness or single moisture resistance of the material is weakened or invalidated, so that it is widely used in the evaluation of the material's weather resistance, and the equipment has the best sunlight UV simulation. It is low in maintenance cost, easy to use, automatic operation of the equipment by control, high degree of automation of the test cycle, good lighting stability, and high reproducibility of test results.
