Lines were drawn on the test paper at a speed of 310±10cm/min. The test paper was removed and fixed on the eraser machine. The eraser test piece was made into vertical contact with the line on the test paper. Under a standard load of 0.5KG, the back-and-forth rubbing test was conducted at a speed of 36±2CM/MIN for four times.
