Black corundum, also known as black silicon carbide, has good hardness, wear resistance, high temperature resistance, and is very similar to brown corundum, but its scope of application is very different. Black corundum can be used for surface polishing of steel, hardware, aluminum and other components. It can also process materials. Brown corundum has high hardness, good wear resistance, good flexibility and high density. Brown corundum can be used in the production and running in of abrasives.

The wear resistance of white corundum is similar to that of black corundum and brown corundum. Its different characteristics are small volume, high density and high corrosion resistance. When we buy, we should first check the purity of white corundum, because the purity of high-quality white fused alumina manufacturer is very high. If the purity of white corundum is not good, then the quality of white corundum will be directly denied. This white corundum must be not good. This is the advantage of white corundum over brown corundum. These are the important places to distinguish the quality of white corundum.

As long as we pay attention to these places when we buy it, there must be no problem. Chrome corundum is a derivative of green silicon carbide. Its appearance is rose. Its hardness is similar to that of white corundum. Its toughness is slightly higher than that of white corundum with high strength, good grinding performance and high grinding accuracy. The abrasives made of this kind of abrasives have good shape retention and similar application range with white corundum, especially suitable for fine grinding and forming grinding of various cutting tools, measuring tools and instrument parts.

It is a good helper for human beings to develop nature. The resistivity of the new material composed of silica sand and petroleum coke is about 1000 Ω· cm2 / m, which is actually equivalent to insulator. When smelting silicon carbide for arrester, more than 5% impurities such as alumina and iron oxide are introduced into the furnace, and the resistance at the end of the furnace is significantly reduced. Smelting green silicon carbide with salt, it melts at high temperature, reducing the resistance at the end of the furnace.

Generally, chrome corundum has better grinding performance than white corundum. In fact, sub white corundum, bauxite corundum or high alumina corundum is a kind of brown fused alumina manufacturer based on bauxite. It is produced by electrofusion of special grade or first grade bauxite in reducing atmosphere and controlled conditions. Reducing agent (carbon), settling agent (iron filings) and decarbonizing agent (iron scale) are added during melting.

In today's various surface treatment methods, sand blasting has the most obvious effect and can adapt to a variety of complex projects. This is because: the fastest and most thorough cleaning of steel surface; only sand blasting can be evaluated with four cleaning grades that have been developed and accepted by everyone; sand blasting process can not only deal with complex and hard to clean surfaces, but also clean the pipeline table if tools are used Surface, the most critical is that sandblasting is the lowest cost of all surface treatments.

In the smelting process, the excessive deoxidizer is used to reduce the TiO2 in the early stage, and the decarburizer or blowing oxygen is added to remove the excessive carbon in the later stage, so as to obtain the sub white fused alumina suppliers. Generally, each woven bag should be packed with 25kg brown corundum sand. The addition of brown corundum can produce high-grade refractory materials, as well as sandpaper visible in daily life, which is also made by the processing of brown corundum.

Generally speaking, brown corundum plays an immeasurable role in industrial production and it has a wide range of applications. The storage of high-purity brown corundum sand shall be separated from other ordinary brown corundum sand to avoid the invasion of impurities. The above are some storage methods of silicon carbide abrasive sand for your sharing. Of course, some corundum sand should be stored according to the specifications. I hope you can pay more attention to the storage of corundum sand in the future. Please read the above storage methods carefully. The above contents are for reference only.
