Abrasive tester | Taber type abrader No.2082

Depending on the paper type (paper for book covers, wrapping, banknotes, etc.), paper is subject to wear and breakage due to various impacts including folding, wrinkling, friction and fluffing that may occur up to the time of its discard.This abrader measures abrasion resistance of paper, fabric, plastic and metal material, and can test painted or plated surfaces as well as laminated or coated surfaces. This abrader incorporates a specimen stage that rotates at a fixed speed and two abrading wheels on the stage that can be rotated at a desired speed. The rotation of the specimen stage drives the wheels to rotate in the opposite directions; the rotating wheel on the right-hand side rubs the specimen from the back toward the near side while the other on the left-hand side rubs it from the front side toward the back. Those rotations create X-shaped friction trajectories crossing each other while wearingout the specimen, with each rotation leaving an arc-shaped trajectory with an external diameter of about 89 mm and an internal diameter of about 63 mm. The abrasion resistance of the specimen is represented by the abrasion loss after a certain number of rotations or the number of rotations that the specimen can withstand before being worn out and penetrated.
