The principle and function of the xenon lamp weathering test box: The xenon lamp weathering test box uses a xenon arc lamp that can simulate the full sunlight spectrum to reproduce the destructive light waves existing in different environments, which can provide a corresponding environment for scientific research, product development and quality control Simulation and accelerated testing.
The climate environment has a great influence on the aging of organic matter, the discoloration of pigments, and the corrosion of metals. Therefore, the aging test is getting more and more attention in rubber, plastics, paint, petrochemical, automobile, textile and other industries. There are many climatic and environmental factors, such as sunlight, temperature, humidity, rain, condensation; harmful gases, dust, etc. It is not comprehensive enough to evaluate the performance of a material by a single environmental factor test, and often passes multiple factors The combined test can simulate the natural conditions as much as possible to make a more correct assessment. Although the outdoor exposure test has good authenticity, the climatic conditions in different seasons are different due to different regions. Therefore, the importance of the test is poor. At the same time, with the continuous improvement of the quality of the sample material, the cycle of the exposure test becomes longer and longer, which cannot meet the needs of the continuous development of scientific research and production.
The weathering test chamber of xenon lamp has six environmental factors such as light, rain, humidity, condensation and 150, and can be adjusted independently. The xenon lamp is used as the light source and has a spectral distribution similar to sunlight. Therefore, the xenon lamp simulates sunlight . At the same time, a wide adjustment range of temperature and humidity is provided for adjustment, and the rain adopts an independent circulation system. Therefore, when necessary, harmful gas substances can be added to the rain water supply source. Changing the cooling water temperature of the sample rack can adjust the amount of condensation on the sample surface and the temperature of the sample surface. Therefore, the xenon lamp weathering test chamber can be used for a combination of multi-factor weather resistance test.
