Application of shakeout Tester in aluminum surface coating abrasion resistance testing

The falling sand Tester plays a key role in testing the wear resistance of anodized films and organic polymer films on aluminum surfaces. This test is designed to evaluate the coating's wear resistance under real-world usage conditions to ensure it maintains stable performance and appearance over long periods of use.

This test uses a specific device to simulate the wear conditions in the real environment by controlling the abrasive to fall freely at a specified height and impact the sample surface. When an abrasive impacts the surface of a sample, it gradually wears away the coating until it wears through. By measuring the shakeout time and the mass or volume of the abrasive, the wear resistance of the coating can be evaluated. This testing method can objectively reflect the performance of the coating when subjected to external wear and provide important reference for manufacturers to optimize product design and production processes.

The falling sand Tester is classified according to different test film types and abrasive types to ensure the accuracy and reliability of the test. For anodized films and anodized electrophoretic paint composite films, the Type A falling sand Tester is usually used; while for organic polymer spray films, the Type B falling sand Tester is used. In addition, the test process is also required to meet a series of environmental and working conditions, such as ambient temperature, relative humidity, wind shelter, etc., to ensure the accuracy and repeatability of test results.

Through the test of the falling sand Tester, problems with the wear resistance of the coating can be discovered and solved in time, improving the quality and performance of the product and extending its service life. This test is of great significance to the development of the coating industry, promoting the advancement of coating technology and expanding the scope of applications.
