Factory direct sales of various types of sandblasting special abrasives, high-quality brown corundum

Brown corundum is a brown artificial corundum obtained by melting and reducing three raw materials: alumina, carbon materials, and iron filings in an electric furnace, hence its name. The main chemical composition of brown corundum is, its content is .-, and it also contains a small amount of etc. Brown corundum brown is made of bauxite and coke (anthracite) as the main raw materials, and is smelted at high temperature in an electric arc furnace. Abrasive tools made of it are suitable for grinding metals with high tensile strength. Such as various general steels, malleable cast iron, hard bronze, etc., and can also produce high-grade refractory materials. Brown corundum has the characteristics of high purity, good crystallization, strong fluidity, low linear expansion coefficient and corrosion resistance. It has been verified by dozens of refractory manufacturing companies that this product does not explode, pulverize or crack during application. In particular, its cost performance is much higher than that of traditional brown corundum, making it the best aggregate and filler for brown corundum refractory materials.
Grades of brown corundum The main component of brown corundum is alumina. The grade is determined by the aluminum content. The lower the aluminum content, the lower the hardness.
The product particle size is produced in accordance with international standards and national standards, and can be processed according to user requirements. The general particle size number is ~3, and its chemical composition varies depending on the particle size. The outstanding feature is that the crystal size is small and impact-resistant. Because it is processed and broken by an autogenous grinder, the particles are mostly spherical particles. The surface is clean and easy to combine with the binder.
Scope of use Brown corundum is called industrial teeth: mainly used in refractory materials, grinding wheels, and sandblasting.
.Sandblasting brown corundum sandblasting abrasive has moderate hardness, high bulk density, no free silica, heavy specific gravity, and good toughness. Aokai brown corundum is an ideal environmentally friendly sandblasting material and is widely used in aluminum profiles. Copper profile glass, washed denim precision molds and other fields
. High-quality grinding and grinding grade abrasives, used in high-quality grinding of picture tubes, optical glass, monocrystalline silicon, lenses, watch glass, crystal glass, jade and other fields , is a high-grade abrasive material commonly used in China
3. Resin abrasive abrasives have suitable color, good hardness, toughness, suitable particle cross-section type and edge retention, and are used in resin abrasives with ideal results
.Coated abrasives are raw materials for sandpaper, gauze and other manufacturers
.Brown corundum functional filler is mainly used in automobile brake parts, special tires, special construction products, etc. It can also be used as a highway pavement construction , airport runways, docks, parking lots, industrial floors, sports venues and other wear-resistant materials
