In the production process of printed circuit boards, the grinding process runs through the entire production process. By grinding the PCB, it is possible to remove fine fibers and dust on the surface of the board, remove dust from micro holes after drilling, and remove the oxide film on the copper surface. PCB board ceramic abrasive roller is an efficient grinding tool. It is usually made of green silicon carbide micro powder (green SiC 600 mesh 800mesh and other models) or aluminum oxide micro powder added with a foaming agent to make an elastic grinding roller. Green SiC powder has superior performance due to its efficient grinding ability.

Silicon carbide is an abrasive sand harder than aluminum oxide. The hardness of SiC is Mohs 9.2-9.5. It is more suitable for grinding marble, stone, glass, and granite than steel and iron. So silicon carbide abrasive sand mostly works as the raw material of hard & fragile abrasive tools.

Green silicon carbide F1500  F2000 are extra fine abrasive powders that have high economic benefits for polishing slurry. Polishing slurry always works in double-sided grinding machines to polish precision parts, mating parts, and optical parts. It achieves the goal of increasing surface smoothness and beautifying products. The double-side grinding works on the base of the relative movement of the workpiece and the grinding tool removes burrs and edges on the surface of the workpiece. The abrasive in the grinding fluid plays a role in improving polishing speed and smoothness.

Before spraying, titanium alloy materials need to remove surface impurities and oxide films. A certain roughness is necessary to ensure the coating sticks firmly on the surface of the titanium material. Green carborundum 24 # blasting media is suitable for making surface treatment of titanium materials

Green carborundum 6000 mesh is an ultrafine powder with a main crystalline phase of α Silicon carbide, with a hexagonal crystal structure. It corresponds to the national standard model of Green silicon carbide W2.5 powder. It is not only a commonly used grinding material in the field of abrasives, but also a raw material for silicon carbide ceramics, thermal materials, coatings, and polymer materials.

The Vickers hardness of tungsten carbide is 1800-2200kg/mm2, and the Rockwell hardness is 65-70HRC. The Vickers hardness of green silicon carbide grinding powder is 3280-3400kg/mm2, which is higher than that of boron carbide. Green silicon carbide 400mesh 600mesh is used for grinding WC coatings.
