Cheap Black Silicon Carbide Suppliers Russia

In the manufacturing of resin abrasive tools, different white fused aluminum oxide process methods and equipment are adopted with the types and properties of resin binders and different requirements for abrasive tools. High speed grinding plate is widely used in grinding welding line, deburring casting and metal surface in metallurgy, chemical industry, shipbuilding and other machining industries.

The raw materials used for resin Abrasives include abrasives, binders and auxiliary materials. The brown fused alumina 60 grit used for resin abrasives are: corundum series such as brown corundum (a), white corundum (WA), single crystal corundum (SA), microcrystalline corundum (MA), chrome corundum (PA), corundum (ZA), black corundum (BA), and silicon carbide series such as black silicon carbide (C), green silicon carbide (GC), cubic silicon carbide (SC).


The white fused alumina used to make resin abrasive tools have low requirements for magnetic content, but strict requirements for surface quality. In order to increase the adaptability of abrasive tools and improve their grinding performance, sometimes different kinds of mixed abrasive must be used, special Abrasives can be made by additional treatment. The common resins are: polyethylene, polyvinyl chloride, polystyrene, etc.


In order to improve the bonding ability of aluminium oxide grit suppliers and binders, and to improve some properties of abrasives (strength, toughness, wear resistance, etc.). There are many methods of abrasive treatment, such as calcination, particle shaping, surface coating, surface corrosion, coupling agent treatment and so on. In summary, all resin Abrasives basically follow the following process flow in the corundum white manufacturing process.


Resin as binder is to bond the loose white aluminum oxide and consolidate them into a certain shape. After heat treatment, it has certain hardness, strength and grinding performance. Therefore, it should have the following conditions: good adhesion to abrasives; good mechanical strength and heat resistance; good process performance, easy to manufacture; low price, sufficient supply; polyacrylic acid, non-toxic or white aluminum oxide blast media low toxicity.


According to the brown fused alumina factory reaction type of synthesis process, artificial (synthetic) resin can be classified into additive type and polycondensation type, which are formed by the addition of unsaturated low molecular compounds or the ring opening of cyclic compounds to form macromolecular reaction. In the reaction process, there is no small molecule by-product. The white aluminum oxide abrasive 220 grit resin produced by the polymerization is a polymerized resin.


It is a polycondensation reaction that two or more low molecular compounds interact to form a polymer, and buy brown fused alumina small molecular compounds such as water, alcohol or HC1 are formed at the same time. The resin formed by polycondensation is polycondensation resin, called polymerization reaction. The common resins are: white fused alumina oxide mfg phenolic resin, epoxy resin, novolac resin, formaldehyde resin, melamine resin, alkyd resin, silicone resin, etc.
