Introduction to Emery
Emery, also called sand derusting Polishing sand, corundum, black corundum, white corundum, silicon carbide known as carborundum, is made of alumina, carbon materials, scrap iron three kinds of raw materials in electric furnace melting reduction of artificial corundum, reason for this name.Emery main chemical composition is AL2O3, and its content from 94.5% to 94.5%, the other contains a small amount of Fe, Si, Ti, etc.
Emery performance indicators
Silicon carbide with high quality bauxite as raw material, anthracite coal, iron, high temperature above 2000 degrees hitches in arc smelting, the mill grinding plastic, magnetic separation to iron, screen is divided into a variety of particle size, dense texture, high hardness, particle formed globular, high consolidation is suitable for making ceramic, resin abrasive and grinding, polishing, sandblasting, precision casting, etc., can also be used for manufacturing advanced refractories.
Application range of corundum
1. Sandblasting, moderate hardness, high packing density, no free silica, than major, good toughness and is the ideal "environmental protection" type sand blasting materials, widely used in aluminum, copper profile glass, washing jeans precision molds, and other fields;
2. The free abrasive, abrasive abrasive, applied to the tube, optical glass, monocrystalline silicon, lenses, clocks with glass, crystal glass, jade in areas such as free grinding, grinding is adopted widely in the domestic advanced materials;
3. The resin abrasive, abrasive has color appropriate, good hardness and toughness, suitable particle cross section type and keeping degree blade, used in resin abrasive, effect is ideal;
4) is coated with abrasive, abrasive paper, gauze and other manufacturers of production materials;
5. The functional filler - is mainly used for automobile brake parts, special tires, special construction products such as led can be used as building highway pavement, airport runway, docks, car parks, industrial floor, wear-resisting material such as sports venues;
6. Filter medium, is a new kind of application field, abrasive using granular grinding for the bottom of the medium filter bed, purify drinking water or wastewater, is a new type of water filtration materials at home and abroad, especially suitable for non-ferrous metal processing, oil drilling mud weighting agent.
7. Hydraulic cutting - is abrasive cutting medium, rely on high pressure water jet cutting, basic application in the oil (gas) pipe, steel components, such as cutting, is a new type, environmental protection, safe way of cutting.
