Scope

This part of GB/T12967 specifies the spray grinding method, falling sand method, paper pulley grinding method, rubber wheel grinding method, rubber friction method and friction coefficient determination method. The spray grinding method is suitable for measuring the wear resistance of anodized films and organic polymer films with a film thickness of not less than 5 μm, and is suitable for smaller samples and samples with uneven surfaces. The falling sand method is suitable for measuring the wear resistance of anodic oxidation films and organic polymer films, and is suitable for smaller samples and samples with uneven surfaces. The paper belt wheel grinding method is suitable for measuring the wear resistance of anodized films and organic polymer films with a thickness of not less than 5 μm. It can determine the overall wear resistance of the film layer and the wear resistance changes along the thickness of the film layer. It is not suitable for surfaces. Rugged specimens. The rubber wheel grinding method is suitable for measuring the wear resistance of anodic oxidation films and organic polymer films. It can be used to determine the overall wear resistance of the film layer. It is not suitable for samples with uneven surfaces. The rubber rubbing method is suitable for measuring the wear resistance of anodized films and anodized composite films with a thickness less than 5 μm. Functional films and textured films can be used as a reference. The friction coefficient measurement method is suitable for products such as aluminum flooring and aluminum foil that require anti-skid properties.
