Production process:First of all high-quality brown fused alumina must be selected.After strict inspection,they are put into saggars and entered into the tunnel kin for high-temperature calcination,heat preservation and cooling processes to ensure the toughness and
appearance of the calcined abrasives.
Product features:Smallexpansion coefficient,cleanliness increased by more than 50%thanbefore calcination,toughness increased by more than 15%than before calcination,thus improving the grinding efficiency of abrasive tools.
Product use:Mainly used for high-grade resin abrasives and coated abrasives.
High temperature calcination Brown Corundum Besides being used in refractory materials, grinding wheel and grinding tool manufacturing, precision casting and other fields, it is also widely used in the following fields
1. Sandblasting-The abrasive has moderate hardness, high bulk density, no free silica, large specific gravity and good toughness. It is an ideal "environment-friendly" sandblasting material, which is widely used in aluminum profile, copper profile glass, precision molds for washed jeans and other fields;
2. Free grinding-grinding grade abrasive, which is used for free grinding in the fields of kinescope, optical glass, monocrystalline silicon, lenses, watch glass, crystal glass, jade articles, etc., and is a widely used advanced grinding material in China;
3. Resin abrasives-abrasives have appropriate color, good hardness, toughness, appropriate particle cross-section type and cutting edge retention, which are applied to resin abrasives with ideal effect;
4. Coated abrasives-abrasives are the raw materials of manufacturers such as sandpaper and gauze;
5. Functional filler-mainly used for automobile brake parts, special tires, special building products, etc. It can be used as wear-resistant materials such as highway pavement, airstrip, wharf, parking lot, industrial floor, stadium, etc.
6. Filter media-it is a new application field of abrasive. Granular abrasive is used as the bottom media of filter bed to purify drinking water or wastewater. It is a new type of water filter material at home and abroad, especially suitable for nonferrous metal beneficiation. Oil drilling mud weighting agent:
7. Hydraulic cutting-it is a new, environmentally friendly and safe cutting method, which uses abrasive as cutting medium and relies on high-pressure hydraulic jet for basic cutting, and is applied to the cutting of oil (natural gas) pipelines, steel and other parts.
