Polymer materials in the use of the process will encounter the problem of climate aging. To predict the weathering resistance of polymer materials. We can realize it through experimental methods. The methods of weathering resistance of polymer materials are divided into two categories. These are the natural climate aging test and artificial climate aging test.
Due to many factors that cause polymer materials aging and complex aging mechanisms. Natural climate aging is undoubtedly the most important and reliable weathering test method. But, the natural climate is not humanly controllable. Subject to time and geographical constraints. Light, water, and temperature in the environment can change at any time. Thus, it is difficult to get consistent results for tests started at different times. This leads to poor repeatability of the test results. Artificial climate aging test makes up for these shortcomings. This method simulates the effect of light, water, and temperature on the specimen. And obtains the test results. And can enhance the natural climate of a factor or several factors. Thus shortening the weathering test cycle. Ultimately gets the effect of accelerating the test process.
As the test conditions can be controlled. The repeatability of the test is also guaranteed. Thus, the artificial climate aging test is as widely used as the natural climate aging test. It is even used more often.
In the world of testing and evaluating the durability of materials, there are 2 tests: Thermal Shock vs. Thermal Cycling Tests. These tests are easy to understand how car parts, ceramics, and electronics work. Even though these tests look similar, they have different reasons. Plus, they perform functions in different ways. In this article, we’ll explain these tests in an easy way and help you decide which one is best for what you need.
