Brown corundum Special etching processing: jade, crystal, agate, semi-precious stones, seals, elegant stones, antiques, marble tombstones, ceramics, wood, bamboo chips, etching art.
Brown corundum, commonly known as emery, is a tan artificial corundum made by melting and reducing three raw materials of bauxite, carbon materials and iron filings in an electric arc furnace, hence the name. The main chemical component of brown corundum is AL2O3, its content is 95.00%-97.00%, and it contains a small amount of Fe, Si, Ti, etc. Brown corundum is the most basic abrasive, because of its good grinding performance, wide range of application, cheap price, widely used.
Brown corundum product advantages:
Brown corundum is called the tooth of industry: mainly used in refractories, grinding wheels, sandblasting.
1. Used in the manufacture of advanced refractory materials, castables, refractory bricks, etc.
2. Sandblasting – moderate hardness of abrasives, high bulk density, no free silica, significant ratio, good toughness, is an ideal “environmental protection” sandblasting material, widely used in aluminum profiles, copper profiles, glass, washed jeans precision molds and other fields;
3. Free grinding – grinding grade abrasives, used in picture tubes, optical glass, single crystal silicon, lenses, watch glass, crystal glass, jade and other fields of free grinding, is a commonly used advanced grinding material in China;
4. Resin abrasives – the abrasive has suitable color, good hardness, toughness, suitable particle section type and cutting edge retention, which is applied to resin abrasives with ideal effect;
5. Coated abrasives – abrasives are the raw materials of sandpaper, gauze and other manufacturers;
Brown corundum segment sand
6. Functional filler – mainly used for automobile brakes, special tires, special building products, etc. can be used as highway pavement. Airstrip. Dock. Parking lot. Industrial flooring. wear-resistant materials such as sports grounds;
7. Filter medium – is a new application field of abrasives, using granular abrasives as the bottom medium of the filter bed, purifying drinking water or wastewater, is a new type of water filtration material at home and abroad, especially suitable for non-ferrous metal beneficiation: oil drilling mud weighter:
8. Hydraulic cutting – is a new, environmentally friendly and safe cutting method based on abrasive cutting medium and relying on high-pressure hydraulic jet for basic cutting, which is applied to the cutting of oil (natural gas) pipelines, steel and other components
