The UV aging test chamber is mainly used to simulate the damage of natural sunlight, humidity, and temperature to materials. Material aging includes fading, loss of gloss, peeling, crushing, strength reduction, cracking, and oxidation. By simulating sunlight, condensation, and natural humidity inside the box, it can be tested in a simulated environment for several days or weeks to reproduce potential damage that may occur within a few months or years.
The light emitted by the lamp tube of the UV aging test chamber can quickly provide test results. The short wavelength ultraviolet light used is stronger compared to common things on Earth. Although the wavelength emitted by ultraviolet tubes is much shorter than the natural wavelength, ultraviolet light can greatly accelerate testing, but it can also cause inconsistent and actual degradation damage to certain materials.
UV tube is a low-pressure mercury lamp that emits ultraviolet light when stimulated with low-pressure mercury (Pa). It is made of pure quartz glass and natural crystal, with a high UV penetration rate, usually reaching 80% -90%. The lighting intensity far exceeds that of ordinary glass tubes. However, over time, the lamp tubes are prone to accumulating dust. So, should the light tubes be wiped regularly?
Firstly, before using a new lamp tube, it can be wiped with a 75% alcohol cotton ball. It is recommended to wipe every two weeks. As long as there is dust or other stains on the surface of the lamp tube. It should be wiped in a timely manner. Keep the lamp tubes clean at all times. To avoid affecting the penetration ability of ultraviolet rays. Another point is that for UV aging test chambers, maintenance is not only required for the lamp tubes. We should regularly maintain and maintain the box.
