Abrasive Industrial Derusting Brown Fused Alumina Brown Adamantine Spar
abrasive material grinding apparatus cutting disk artificial abrasive Industrial derusting brown adamantine spar
Product name: section sand of brown fused alumina
Specification: 320#
MAIN APPLICATIONS
1.Sandblasting-abrasive moderate hardness, high bulk density, no free silica, high specific gravity, good toughness, is an ideal ' environmental protection ' type sandblasting material, widely used in aluminum profiles, copper profiles, glass, precision mold and other fields.
2.Free grinding-Grinding grade abrasive used in kinescope, optical glass, single crystal silicon, lens, clock glass, crystal glass, jade and other fields of free grinding, is widely used in domestic advanced grinding materials.
Resin abrasive-abrasive has suitable color, good hardness, toughness, suitable particle section type and edge retention, can be used as filler instead of 20 % -30 % brown corundum used in resin abrasive, the effect is ideal.
4.Coated abrasive-abrasive is the raw material of sandpaper, gauze and other manufacturers.
5.Functional filler-mainly used in automotive brake parts, special tires, special building products and other fields, can be used as the construction of highway pavement. Aircraft runway. The pier. Parking lot. Industrial floor. Wear-resistant materials such as sports venues.
6.Filtration medium-New application field, the use of granular as the bottom medium of the filter bed to purify drinking water or wastewater, is a new type of water filtration material at home and abroad, especially for non-ferrous metal beneficiation : oil drilling mud weighting agent.
7.Water knife cutting-abrasive cutting medium, relying on high-pressure hydraulic jet for basic cutting, used in oil ( natural gas ) pipeline, steel and other parts of the cutting, is a new, environmentally friendly, safe cutting method.
