Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of polymer plastic film detection, in particular to a device used for polymer plastic film. Background Art
[0002] The wear resistance test of plastic film usually involves specific test methods. A common method is to use a haze tester and a tribometer to test the anti-friction degree of plastic film. This method first determines the original haze value of the plastic film sample, and then performs an external-to-external friction test on the tribometer. After the test is completed, the haze value of the film after friction is measured again using the haze meter. By comparing the haze values before and after friction, the wear resistance of the plastic film can be quantitatively evaluated.
[0003] However, there are many factors that affect the wear resistance of plastic films. For example, at different temperatures and when different pressures are applied, the same friction will cause the degree of wear of the plastic film to be different. If the detection equipment can only detect the degree of wear under normal conditions, the entire detection equipment will have certain limitations. Utility Model Content
