Abrasive knowledge

Is an adhesive bonded abrasive cloth, paper can be made ​​of a flexible material can be ground and polished tool. It is with the grinding wheel, sand tile, Whetstone, grinding, polishing paste, together, polycrystalline diamond six varieties. Coated abrasives composed of three parts: a base, abrasives and adhesives, also known as the three elements. From cross-sectional view of coated abrasives can clearly see the structure of coated abrasives. The base substrate is a carrier of abrasive and binder, which is coated with a flexible grinding dominant factor. Substrate coated abrasives are: cloth, paper, fiber and composite matrix, woven fabrics and other types abrasive wheels in the manufacture of abrasive, you must go through specialized treatment, must undergo special treatment, the performance of the matrix with its own species related but also relating to the method to be treated. The substrate processing is performed by the base treatment agent toabrasive grinding enhance the physical and mechanical properties of the substrate, coating plant sand and grinding meet use process. General matrix processing into non-water treatment and water treatment into two categories, according to the ground conditions are different, the substrate can also be softening, osmophilic processing, oil processing and electrostatic treatment. Abrasive grinding action is from the part, commonly used corundum, silicon carbide, natural corundum, etc. Abrasive particle size and composition of the coated abrasives meet the national standard. Sand-planting density planting density on the coated abrasive sand quality and performance is also an important factor, which represents the per unit area on the substrate abrasive density level. Abrasive and the adhesive binder firmly bonded with the substrate, which may be the end of plastic, rubber and matrix complex treatment agent.
