The weather resistance of polymer materials for environmental test materials is the normal service life of materials. The test methods for evaluating the life of polymer materials in the natural environment include outdoor aging tests and artificial aging tests. Outdoor aging test is the most suitable method for evaluating the practicability of materials, but causing aging of polymer materials is a combination of heat, light, mechanical friction, chemicals, microbes and other factors, and the sunshine, wind and rain are difficult to control climate. Factors, so the test cycle is longer. Accelerated weathering tests in the laboratory to simulate outdoor climate conditions are an important way of weathering tests. The weathering test is usually conducted using a weathering test box. The device uses carbon arc lamp, xenon lamp or ultraviolet fluorescent lamp to irradiate ultraviolet rays in simulated sunlight, and periodically sprays the sample with salt solution to simulate the effects of rainfall and salt particles. Multiple environmental factors are used. Alternating effects constitute the test process.
Common accelerated weathering test chambers include ultraviolet aging test chambers, xenon lamp aging test chambers, salt spray test chambers, and constant temperature and humidity test chambers, among which the ultraviolet aging test chamber and the xenon aging test chamber simulate the aging of materials caused by sunlight irradiation. It can speed up the simulation of this aging phenomenon. In the field of photoaging weathering test is widely used. As mentioned earlier in the Salt Spray Test Chamber, it is to periodically spray the sample with salt solution to simulate the effects of rainfall and salt particles. It is mainly used for accelerating salt spray corrosion test of industrial products such as protective layers of metallic materials. The constant temperature and humidity test box is a temperature and humidity test equipment as its name implies, and its main function is to apply temperature and humidity conditions to the test material to detect the weather resistance of the material under changing temperature environment. These devices are the most common in the field of environmental testing equipment, and are also widely used in the weather resistance test of polymer materials.
This classification mainly includes the aluminum alloy die casting CNC Turning parts using in machinery area,the raw material is aluminum alloy or zinc alloy.In the die casting process,higher specific pressure is required, so that higher filling speed can be obtained.which is beneficial for alloy to overcome mold filling resistance.and effectively fill each part of the cavity.The Casting General Tolerance is Grade GB-CT4.
