Green silicon carbide abrasive is an important participant in the production of solid carbide tools. It is suitable for the passivation of blade edges, and surface treatment before cemented carbide powder coating spraying. And polishing inserts or drills after powder coating.
Silicon carbide is a high-temperature and high-power semiconductor material in the semiconductor field. However, there is a fundamental difference between silicon carbide semiconductor materials and silicon carbide abrasive materials in the field of grinding. Silicon carbide in the semiconductor industry is a single crystal grown by PVT or HTCVD method. It shows different conductivity with temperature change. In the field of grinding, silicon carbide powder is a silicon carbide polymer produced by high-temperature melting and smelting. It is an insulting material at room temperature and suitable for making silicon carbide functional ceramics.
Abrasive brushes made from SiC abrasive filament are suitable for grinding and cleaning difficult-to-clean tubular or porous metal castings. The substrate of abrasive brush wire is nano-modified nylon. It is elastic and gets bending properties. Black silicon carbide is the main material. Mixing SiC abrasive material and Nylon together to produce nylon abrasive filament. Then adopt an abrasive filament to produce an abrasive filament disc or brush. The mostly used grits are black silicon carbide F36-F220 abrasive grain and black silicon carbide powder F240-F400.
Silicon carbide and boron carbide are commonly raw materials in the grinding and ceramic industries. Both the two materials have high hardness and high-temperature resistance. However, both silicon carbide and boron carbide have different characteristics in terms of usage scenarios and high-temperature performance.
Black & green carborundum powder is a terrific ingredient for oxidation-resistant coating. Especially for the key components in industries such as power plants, mines, petrochemicals, and marine turbine equipment. The pipelines, kiln, critical conveying components, engine blades, and large pumps are always exposed to the corrosive environment. Wearing and anti-corrosion treatment of these components can improve their service life and reduce failure rates. In most cases, anti-corrosion and oxidation-resistant coatings with carborundum powder ingredients are suitable for pre-treatment and repair.
Green Silicon carbide grain for desulfurization nozzles is the main material for silicon carbide spray nozzles. In fossil-fuel power plants and large boilers, silicon carbide ceramic nozzle is an important part of a wet desulfurization spray system. The gas generated in power plants or boilers contains a large amount of SO2, which seriously pollutes the environment. In today’s increasing emphasis on environmental protection, thermal power plants are adding desulfurization devices before gas emissions to reduce SO2 emissions. As a key component of the desulfurization system, silicon carbide should have strong oxidation resistance, corrosion resistance, and durability when in long-term contact with corrosive gases such as sulfur dioxide, sulfite, sulfuric acid, and absorbent slurry.
