What is the natural aging test and artificial accelerated aging test product material in the process of storage, use, will be affected by the natural environment of low temperature, high temperature, humidity, rain conditions, after a period of time, the material appears to use unstable performance, physical machinery The performance is damaged. This is what we call aging.
In order to test the aging properties of the product materials, people have summarized two methods of aging test: First, the natural aging test, which is the direct use of the natural environment for aging test, no manual intervention; the other is the artificial accelerated aging test, that is, the use of aging test The box simulates some of the aging factors of the natural environment for aging tests.
The natural aging test is more accurate than the artificial accelerated aging test. The test results are more accurate, because the aging factors are various, and the test data obtained from the natural environment aging is undoubtedly more reliable. However, it also has limitations, because the natural aging test cycle is relatively long. The differences in climate conditions in different years, seasons, and regions have led to incomparable test results. Therefore, artificial accelerated aging tests are now used instead.
Artificial accelerated aging test Through the relevant system device of the test box can simulate the aging factors in the natural climate, such as sunlight, temperature, humidity, rainfall, etc., greatly shortened the aging test cycle, and the test conditions of the test chamber can be controlled, The test results are reproducible, but the accuracy of the test results may not be as high as the natural aging test. However, artificial accelerated aging test is used instead of natural aging test method because the society is fast-paced and it is impossible to wait for the slowness of the natural aging test. Test results, and the results are less comparable.
Artificial aging test is used as a supplement and alternative test of natural aging. Just as the ultraviolet aging test box replaces the natural environment exposure test, it is widely used in the research of polymer materials and the testing of product material performance.
