Which industrial fields are brown fused alumina used in?

Brown fused alumina is called the tooth of industry: it is mainly used in refractory materials, grinding wheels, and sandblasting.

1. Used in the manufacture of advanced refractory materials, castables, refractory bricks, etc.

2. Sandblasting—the abrasive has moderate hardness, high bulk density, no free silica, large specificity, and good toughness. It is an ideal “environmental protection” sandblasting material, widely used in aluminum profiles, copper profiles, glass, and washed jeans Precision molds and other fields;

3. Free grinding—grinding grade abrasives, which are used in free grinding in the fields of picture tubes, optical glass, single crystal silicon, lenses, watch glass, crystal glass, jade, etc. It is a high-grade grinding material commonly used in China;

4. Resin Abrasives—Abrasives have suitable color, good hardness, toughness, suitable particle section type and edge retention, and are applied to resin abrasives with ideal results;

5. Coated abrasives – abrasives are raw materials for sandpaper, gauze and other manufacturers;

6. Functional fillers—mainly used for automobile brake parts, special tires, special construction products, etc., and can be used as wear-resistant materials for building highway pavements, airstrips, docks, parking lots, industrial floors, and sports venues;

7. Filter media——a new application field of abrasives. Granular abrasives are used as the bottom medium of the filter bed to purify drinking water or waste water. It is a new type of water filter material at home and abroad, especially suitable for non-ferrous metal beneficiation: oil drilling mud weighting agent :

8. Hydraulic cutting – using abrasives as the cutting medium, relying on high-pressure water jets for basic cutting, applied to the cutting of oil (natural gas) pipelines, steel and other components, it is a new, environmentally friendly and safe cutting method.
