Taber Abrasion Tester is applicable to determine the abrasion resistance performance of various coating. It is also used to determine the abrasion resistance of paper, plastics, textile fabric, decorations, etc. The principle of abrasion was derived from the test sample, turning on a vertical axis, against the sliding rotation of 2 abrading wheels. The wheels are driven by the sample in opposite directions about a horizontal axis displaced tangentially from the axis of the sample. One of the abrading wheels rubs the specimen outward toward the periphery and the other wheel, inward to the center. The area of abrasion from a pattern of crossed arcs of about 30 sq. cm.
The degree of abrasion for the specimen also depends on the load force(500g, 750g, 1000g on each arm) being acted onto the axial of the 2Arms, which has a load pressure of 250g.
