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.
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.
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.
In the rice-milling machine, there is a necessary milling roller to remove the rice grain husk. It can improve the rice chaff removal efficiency. The milling roller is always made from silicon carbide abrasives or attached black silicon carbide abrasive grains on the milling lining.
Green silicon carbide powder 2500#, 3000#, 4000#, and 6000# are the main grinding media for photoelectric wafer grinding. In the semiconductor industry, green silicon carbide powder 2000 to 2500 meshes was once used as the mainstream material for wire cutting of silicon wafers. With the development of wire-cutting technology and the mass production of synthetic diamond powder, diamond powder gradually replaces green silicon carbide powder. However, in the photoelectric industry, green silicon carbide powder still plays an important role in the grinding field.
