The first choice for the study of natural conditions that cause aging of materials is the xenon lamp aging test chamber. The unique function and perfect combination of parameters make the experiment much easier. The xenon lamp aging test chamber is mainly used for scientific simulation, acceleration and test for scientific research, product development and quality control. The main factors causing the aging of materials are sunlight, temperature, humidity, rain, and condensation. Harmful gases are dusty. It is not comprehensive enough to assess the performance of a material by a single environmental factor test. It is often necessary to test the composition of multiple factors and simulate natural conditions as much as possible to make a more accurate assessment. Although the indoor exposure test has good authenticity, different seasonal conditions vary from region to region. Therefore, the test is of less importance. At the same time, with the continuous improvement of the quality of sample materials, the cycle of exposure testing is getting longer and longer, which cannot meet the needs of the continuous development of scientific research and production.
The xenon lamp aging test chamber has six environmental factors such as light, rain, humidity, condensation and military standard 150. Moreover, it can be adjusted independently, using a xenon lamp as a light source and having a spectral distribution similar to that of sunlight. Therefore, the Xenon lamp simulates the sunlight, and the temperature and humidity are widely adjusted. The rain is taken by an independent circulation system. Therefore, if necessary, the harmful gas substances can be added to the water supply source. By changing the water temperature of the sample rack cooling, the amount of condensation on the surface of the sample and the surface temperature of the sample can be adjusted. Therefore, the xenon lamp aging test chamber can be used as a combination test for multi-factor weather resistance.
The hand crank Standing Desk is to rotate the gear through the hand rocker, and then drive the lifting spindle to rise and fall to achieve the purpose of adjusting the height of the desk and chair
