Application of shakeout Tester in organic polymer film abrasion resistance testing

With the continuous development of science and technology, organic polymer membranes are increasingly used in industry and daily life. However, for this type of membrane material, the evaluation of its wear resistance is a crucial issue. In this context, the falling sand Tester, as a commonly used testing equipment, plays an important role in the abrasion resistance test of organic polymer films.

The working principle of the falling sand Tester is very simple and straightforward. By selecting the specified abrasives, the falling sand Tester simulates the wear conditions in the real environment, and evaluates the wear resistance of the film layer based on the falling sand time and the mass or volume of the falling abrasives. This testing method can objectively and intuitively evaluate the wear resistance of the film layer, providing an important reference for product design and production.

The falling sand Tester is divided into two types according to different test film types and abrasive types: Type A is suitable for anodized films, anodized electrophoretic paint composite films, using silicon carbide abrasives; Type B is suitable for organic polymer spray films , use standard sand abrasives. Different types of falling sand Testers have different structural designs and material requirements, but their basic principles and test methods are similar.

The performance requirements of the falling sand Tester are crucial to the accuracy and reliability of the test results. For example, indicators such as the shakeout state, abrasive flow rate, abrasive concentration, and the ratio of the long and short axes of the wear marks should comply with the standards to ensure the comparability and reliability of the test results. In addition, the environment and working conditions of the falling sand Tester should also meet certain requirements, such as ambient temperature, relative humidity, wind shelter and foundation levelness, etc.

In summary, the falling sand Tester has important application value in testing the abrasion resistance of organic polymer films. Through this test method, the wear resistance of organic polymer membranes can be objectively and accurately evaluated, providing an important reference for product design and production, and promoting the development and application of organic polymer membrane materials.
