Project Introduction

The abrasion tester uses a special paper belt as the friction medium, and a fixed load acts on the friction head. The friction head drives the paper belt driven by the fixed diameter roller and the fixed speed motor to continuously apply force to the surface of the sample until When the surface substrate or a specific degree of wear is reached, the abrasion resistance of the sample is evaluated by the number of motor revolutions indicated by the counter.

Application range

The paper tape abrasion tester is suitable for the abrasion resistance test of various surface coating (electroplating, baking paint, screen printing, etc.) samples. After rolling the non-oiled paper or tape and the sample and rubbing it under a certain number of revolutions Determine the effect of its wear.

Method Standard

ASTM F 2357-04 RCA paper tape wear test
