AI Technical Summary

Problems solved by technology

[0003] The common UV aging environment box will generate a lot of heat when it is working, and it cannot guarantee a constant temperature, which will cause the material to undergo thermal aging while photoaging, thus failing to meet the requirements of the test.

The aging of materials is often affected by many factors such as light, temperature, humidity, etc. At this time, it is usually necessary to use each aging environment chamber for aging tests, resulting in long test periods, high test costs, and low utilization of test equipment

In addition, the UV lamps of the commonly used UV aging environmental chambers that can simulate the influence of humidity are easily affected by water vapor, and the environmental chambers are small in size, which cannot meet the needs of large-volume test pieces in engineering.
