Carborundum, SiC, also known as silicon carbide. Pure colorless crystals. Density of 3.06 to 3.20. Hardness, about the Mohs 9.5 degrees. Average is a colorless powder particles. After grinding, grinding powder, can be prepared polishing paper, but also the system friction surface of the grinding wheel and grindstones. Sand and the amount of carbon in the electric furnace, to strengthen thermal system. Natural corundum, also known as Garnet sand, silicate minerals. After the hydraulic sorting, made of abrasive material for mechanical processing, filtering and classification methods. The production has a long history of ancient China had emery grinding crystal glass, a variety of jade historical examples. 1840s and exported to Japan. Sub-coarse mesh, mesh, breakdown of three categories. Coarse mesh of black and red, the head is pale red, the breakdown of red and white, the various heads of uniform particle size, particle shape uniformity into the edge is called the angle of crystal, sharp edges, grinding force. For stone industrial grinding marble and other soft materials. Glass industrial grinding glass edges, the TV picture tubes, optical equipment, lenses, prisms, watch glass. Metal industrial sandblasting, rust, grinding. Grinding offset printing industry, as well as light industry and processing of plastic-like leather, sandpaper and other purposes. Natural corundum grinding force was slightly lower than the furnace white fused alumina, but its wayward, with shell-shaped section of the characteristics of the mouth, the finish grinding parts, sand marks few and shallow. Fine grinding and uniform, improve product quality, Emery is unique. Natural diamond grinding time is short, high efficiency, low cost, and can make up for the lack of short life. The natural emery suitable for sandblasting, rust, polishing and other purposes. Widely used in electronics, microelectronics, telecommunications, computer room, optical, biochemical, pharmaceutical, food, printing, chemicals, medical equipment, precision machinery, electroplating, plastic hardware, spraying workshop and automobile manufacturing and other industries. 1, Scope:, warehouses, airports, docks, parking lots, metal works, electrical plants, heavy machinery plant, repair factory, warehouse-style shopping malls and other ground. 2, Features:, mechanical properties, excellent wear resistance, hard wearing floor surface. The abrasion resistance of 285% of the ordinary concrete, Mohs hardness of greater than 8. The overall conservation thereby forming a uniform concrete floors, having excellent impact resistance and resistance to point load capacity, surface strength greater than 70Mpa. Short construction period, no pollution, is the best material for the alternative terrazzo floor. From the construction, maintenance and service life compared with the most economical and practical. Garnet sand, garnet abrasive this product to the natural quality Zhongtiaoshan garnet mine raw materials, and refined by modern technology sticks, self-sharpening grinding efficiency and low sand consumption, wear parts is a good finish. Shell-shaped fracture of the abrasive, moderate hardness, good toughness and sharp corners, the formation of new edges and the side edge continuously graded crushed, its grinding capacity than other abrasives. It has high hardness. Heavy. Chemically stable and its unique self-sharpening advantages, so that it has the other abrasives, abrasive man-made irreplaceable advantages, grinding, polishing glass bulb. Ideal material for monocrystalline silicon; the lens of the optical industry. grinding of the lens on the print edition. glass, crystal, ceramic products leather stone layer of plastic nuclear pollution protection and electrical degree processing, can get good results; also the sand-blasting, grinding wheel manufacturing and high fine sandpaper, emery cloth, abrasive paste, cutting discs; water is an ideal material for cutting sand; than significant. chemically stable, water filtration media, water purification; It is resistant to acid. alkali, and use it for filling agent manufacture of wear-resistant rubber wear-resistant plastic, anti-slip paint and other new products; cement filler use it, can be made efficient wear-resistant cement, construction of highway. runway pier entrance of the hotel car park. sporting venues. wear-resistant flooring and other high-end building materials; micro-level products, applied to the tile surface. "permanent" wear-resistant floor tiles can be made to improve the performance of the floor tiles wear non-slip and strength.
