Ceramic roller cover rubber is a way of cold vulcanization of roller cover rubber, the surface increases 20mmX20mm specifications of 95 wear-resistant alumina corundum ceramics, the surface of each piece of ceramic rubber plate by casting hundreds of small independent ceramic pieces into the durable rubber plate, each piece of ceramic piece has a raised feature, under the general pressure of the conveyor belt, the thousands of uniquely cast bumps can produce positive traction to prevent skidding , extending the life of the conveyor belt rollers. At the same time, the elasticity possessed by the underlying rubber provides excellent impact resistance. The semi-sulfurized CN layer added in the rubber sheet is a specially made semi-sulfurized layer, which has a strong cold sulfur chemical reaction with the adhesive in the process of bonding with the roller, and the super wear-resistant ceramic sheet on the surface of the rubber sheet increases the abrasion resistance and coefficient of friction of the rubber sheet, so that the roller can maintain a strong bonding with the rubber sheet and super wear-resistant no matter in any harsh environment.
