GB/T 1768-1979 《Determination of film abrasion resistance》 Related products

The GB/T 1768-1979 standard specifies a method for measuring the wear resistance performance of paint films. The method uses a paint film Wear resistance instrument to perform a specified number of wear rotations under a certain load, and then evaluates the wear resistance performance of the paint film by the weight loss of the paint film. The standard describes in detail the materials and equipment required for the experiment, including Glass Plate, Balance, paint film Wear resistance instrument, etc. The measurement method depends on the different paint film Preparative, including the treatment flow of self-drying paint and volatile paint. Humidity needs to be strictly controlled during the test, and parallel tests are carried out to ensure the Reliability of the results. The appendix describes in detail the method of reforming rubber abrasive wheels to ensure accuracy and conformity for each test.
