1、 The purpose of the UV weather resistance test chamber is:

The UV weather resistance test chamber is mainly used for artificial accelerated testing of plastic, coating, and rubber materials under simulated environments of sunlight, rain, and dew. useUVThe reason for the light tubes is that they are more stable than other light tubes and can better reproduce the test results. The use of fluorescent ultraviolet lamps to simulate the effects of light on physical properties, such as decreased brightness, fading, peeling, etc., is the best method. Most ultraviolet fluorescent tubes produce ultraviolet light, rather than visible and infrared light. The short wavelengths they useUVMore than what is usually found on the surface of the Earth at presentUVLight waves are stronger. Although these are much shorter than natural wavesUVLight can accelerate experiments to the greatest extent possible, used to evaluate changes in materials such as fading, color change, gloss, cracking, blistering, brittleness, oxidation, etc. This provides a basis for improving material formulations and enhancing product performance. After testing, the performance of the product is judged through inspection to determine whether it still meets the predetermined requirements, for the purpose of product design, improvement, identification, and factory inspection.

12、UVA-340The best choice for simulating sunlight ultraviolet rays,UVA-340It can simulate the critical short wave wavelength range of sunlight spectrum very well, that is, the wavelength range is295to360nmThe spectrum.UVA-340Only produced in sunlight that can be foundUVSpectrum of wavelengths.UVB-313For maximum acceleration testing,UVB-313Can provide test results quickly.

13Exposure method: Steam condensation mechanism, the surface of the sample enters a simulated non irradiated state at night after a specified irradiation time. At this time, the surface of the sample is still heated by a saturated mixture of hot air and water vapor in the exposure chamber, while the back of the sample continues to be cooled by the surrounding air, forming an exposed state of condensation on the surface of the sample. 　　

14UV irradiation sensor (optional),Z-UVThe UV lamp weather resistance test chamber is equipped with a UV irradiation sensor. It is a high-precision photometric control system that allows users to select the desired illuminance. Continuous monitoring of light intensity is possible. And fully automated precise maintenance. It can make timely corrections to the light energy caused by lamp aging or any other changes by adjusting the energy of the lamp tube.
