中文 CNWhat are the methods for testing the strength of PVC decorative films?
1. Hardness testing method:
Hardness is an important indicator for measuring the compressive performance of PVC decorative films, and commonly used testing methods include Du's hardness testing and Long's hardness testing.
Among them, the Du hardness test mainly uses a hardness tester to indent the surface of PVC decorative film with a certain force,
Determine the hardness of the decorative film by measuring the depth of the indentation.
Long's hardness testing involves placing a decorative film on a flat plate and then scratching it from different directions using a material with a certain hardness,
If there are scratches on the surface of the decorative film, it indicates that the hardness of the decorative film is low.
2. Test method for destructive strength:
The destructive strength is an indicator of the tensile and tear resistance of PVC decorative films, and commonly used testing methods include tensile strength testing and tear strength testing.
Tensile strength testing involves cutting PVC decorative film into test specimens according to a certain size,
Then stretch the sample through the Tensile testing machine, and record the maximum tensile force and breaking strength.
Tear strength testing is the process of cutting decorative films into specimens of a certain size, and then using the tear method to test, recording the required force and tear length during the tearing process.
