Xenon lamp aging and ultraviolet aging definitions
Xenon lamp aging refers to the use of xenon lamp as a light source for simulating the lighting conditions in the environment and conducting aging tests on materials. Ultraviolet aging refers to the simulation of long-term ultraviolet irradiation of materials in natural environments through photocatalytic reactions to evaluate the weatherability and life of materials.
Mechanism of xenon lamp aging and ultraviolet aging
Xenon lamp aging is through the full spectrum of light generated by xenon lamp, long-term continuous irradiation of materials, and accelerate the aging of materials. The main mechanism of xenon lamp aging is oxidation, cracking and deterioration. Ultraviolet aging is the direct irradiation of ultraviolet wavelength energy on the surface of the material, which causes the chemical reaction of the material and accelerates the aging. The main mechanism involves chemical reactions such as photooxidation, photolysis, photopolymerization and photodegradation.
Effects of xenon lamp aging and ultraviolet aging on test materials
The purpose of xenon lamp aging test is to simulate the lighting conditions in the real environment, to determine the service life and weather resistance of the material, and to test the effect of pigment, opaque foil and fiber materials more accurately. Ultraviolet aging is to evaluate the durability of materials under long-term sunlight irradiation conditions, and has a good test effect on materials such as wallpaper, flooring, plastic wood, and paint.
