With the development of industrial demand, the requirements of wire UV-resistant UV are more and more widely used. Most of our customers in the industrial field have this requirement. With years of rich manufacturing experience, our wire has passed the UV-resistant aging test.
The UV aging test is mainly to simulate the degradation effect of ultraviolet light in sunlight on the product. At the same time, it can also reproduce the damage caused by rainwater and dew; by exposing the material to be tested to the controlled cycle of sunlight and moisture, and increasing the temperature to test, using ultraviolet fluorescent light to simulate sunlight, while still The moisture effect can be simulated by condensation or spraying.
Mainly from the following aspects:
1. Color change before and after illumination;
2. Gloss changes before and after illumination;
3. If cracking has occurred, list the crack depth.
