Artificially accelerated xenon lamp aging chamber for plastic industry testing

In daily life, the exposure to sunlight is a very common environmental phenomenon. Coatings, plastics and other polymer materials are often subject to discoloration, chalking, blistering, cracking, peeling and other phenomena during long-term use by sunlight exposure, which seriously affects the mechanical properties, appearance performance and other characteristics of the products.OCzTextile Testing Instruments, Testing Equipment Manufacturer

Therefore, in the development of coatings, plastics and some automotive interiors, products that are often exposed to light environment conditions need to simulate natural use conditions, i.e., artificially accelerated xenon lamp aging chamber to evaluate them to provide a basis for evaluation. At the same time, in order to quickly assess the performance of materials, the artificially accelerated xenon lamp aging chamber test is often used in the light aging test of new materials.OCzTextile Testing Instruments, Testing Equipment Manufacturer

The spectral energy of several artificially accelerated light aging test light sources varies on the simulated nature of daylight. At present, when various test standards describe the spectral energy distribution of light sources, the total irradiance and the irradiance distribution of each spectral band (or the percentage of energy in each spectral band) are usually given, and the tolerance range of each band is also listed.OCzTextile Testing Instruments, Testing Equipment Manufacturer

The destructive effect of light in a higher temperature environment usually increases the internal light test equipment is usually controlled by controlling the temperature of the black plate (non-insulated black plate), the black standard (insulated black plate) temperature, and the temperature inside the test chamber to control the temperature conditions in the test conditions. Each standard will generally be in the test conditions for one or both of the temperature requirements.OCzTextile Testing Instruments, Testing Equipment Manufacturer
