The principle of RCA paper tape abrasion resistance testing machine for testing the abrasion resistance of paint film

RCA Paper Tape Abrasion Resistance Testing Machine is used to test the abrasion resistance of paint films and coating samples. It is also called RCA paper strip abrasion resistance testing machine.
Sample production:
After electrostatic wiping and dusting of the substrate, spraying, printing or electroplating is carried out to prepare a sample of fixed specifications coated with one or more flat paint films to ensure that the surface of the sample is The appearance of the paint film is normal, without scratches, scuffs, scratches or other abnormal phenomena. The number of samples can guarantee at least 3 effective tests. Use a gloss meter to measure the original 20° An gloss and the original 60° gloss of each sample. Brightness Bn and original haze value Cn;
Adjustment and debuggingge:
Set the number of cycles to 10-30 times, the paper belt moving speed to 30-40 rpm, and place the product on the paper. the belt abrasion resistance tester, with the paint film side facing up, keep it parallel to the horizontal plane, apply a load and adjust the balance rod so that the pressure applied to the surface of paint film is either 175 g or 275 g.
Experimental test:
Start the test button to perform the test. When the set number of cycles is reached, remove the sample, reset the sample on the Paper Tape Abrasion Resistance Tester and continue cycling and scrubbing until the layer is worn away. Paint film, exposed base material or bottom paint film, record the number of wear turns.
