Product description
The word erasure rate tester is composed of two machines, namely the colored paper making machine and the eraser machine. First, a high-grade HB pencil sharpened to 0.6MM was used to contact the test paper fixed on the drum of the test paper making machine at a 75-degree Angle under a load of 0.3kgf. 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. After that, the test paper was removed and the concentration was determined with a lead core concentration meter. This machine can also be used for the eraser wear rate test.
