Emery general term, silicon carbide, also can be brown fused alumina, also can be a black corundum (SiC, also known as silicon carbide), or white corundum.Pure is a colorless crystals, density of 3.06 3.20.Hardness is very big, is about 9.5 degrees Morse, generally is colorless powder particles, after grinding, can be used as a polishing powder, polishing paper could be prepared, but also grinding wheel and strop friction surface.By the sand and the right amount of carbon in electric furnace to strengthen heat.
emery characteristics
Emery inside contain no cause silicosis free silicon harmful substances, do not contain toxic or radioactive pollution of heavy metals, because the product density is larger, seldom produce dust, effectively guarantee the operator's health, in addition, the characteristics of the low consumption and recycled products can greatly reduce the waste after the products use processing and cost.

emery USES
Emery grinding, grinding can be used as a powder, can be polishing paper, and friction surface of grinding wheel and strop stone.Production with a long history, the ancient Chinese have use carborundum crystal glass, all kinds of jade case history.In the 1840 s and are exported to Japan.In the coarse mesh, mesh, detail three categories.All kinds of mesh granularity and the particle shape, uniform into edge Angle of crystal, with a sharp edge, high grinding force.For class industrial grinding stone marble and other soft materials.Burrs grinding glass, glass industry TV picture tube, optical instruments, lenses, prisms, clock and watch glass, etc.Metals industry sandblasting, derusting, grinding.Grinding offset printing industry, plastic processing and light industry, leather, sandpaper and other purposes.Emery willfulness is strong, with conchoidal segment of features, its advantage is a high degree of finish, grinding sand marks and shallow.Ground surface fine and homogeneous, can improve the quality of products.Corundum grinding time is short, high efficiency, low price, can make up for the inadequacy of short life.
Emery is very suitable for a variety of fields, with efficient utilization, it can be reused for 5 times, if after the 5 times is not lost its cutting ability, cycle times can be more.Emery can also after no cutting ability, recycling is applied in the construction industry, again as cement additive, do not need to replace the existing sand blasting equipment, price moderate, high cost performance.Jeans washing emery is washing factory, water cutting industry quality with sand.Water emery under certain pressure, to a large number of rapidly with a sharp object surface edges and corners, it could be seen as a very fast way of jet mill, two times faster than other conventional abrasive.
1, silicon carbide with high temperature resistance, corrosion resistance, high strength, such as performance, so use casting steel slide gate, and special alloy smelting rare metals, ceramics, blast furnace lining (wall and pipe);Physical and chemical vessels, spark plugs, heat-resistant oxidation coating.
2, because of the characteristics of high hardness, good wear resistance, high strength, in the chemical industry system, used for all sorts of reaction vessel and pipe, chemical pump parts;To do mechanical parts, all kinds of mold, such as wire drawing die, such as pencil lead mold mouth;Do abrasive tool, mould, bulletproof material, human body joint, seal die ring, etc.
3, corundum insulation materials, such as corundum light brick, alumina hollow ball and fibre products, widely used in various high temperature furnaces of furnace wall and furnace top, high temperature resistant and heat preservation.Emery sand particle size is by the artificial corundum block, the mark of roller, ball mill, such as equipment and granularity by F8 - F325. Mainly used for polishing, grinding, grinding industry, etc., can also according to customer requirements for water washing, acid pickling treatment methods such as processing, able to meet the different needs of customers. 
4, low carbon corundum and special process in the run-up to the furnace processing, reduce the residual carbon content in the brown fused alumina, make the product in use not pulverization, not burst, great toughness is abrasives industry, refractory industry of choice for raw materials.Mainly used in ceramic grinding tool, high-grade abrasive, abrasive, abrasive belt, coated with organic grinding tool, etc., according to the residual carbon content is divided into: calcined corundum C 0.05 or less, low carbon corundum C 0.10 or less, the common brown corundum C 0.15 or less.
