Green silicon carbide production process and application

Time:2022-7-13 15:46:23 
Green silicon carbide is made of petroleum coke and high-quality silica as the main raw materials, adding salt as an additive, and smelted at high temperature in a resistance furnace. It is green crystal, brittle and sharp, and has certain thermal conductivity and electrical conductivity.

Green silicon carbide micropowder is made of high-quality large crystalline silicon carbide blocks, crushed, shaped by vertical ball mill, pickled with water, precision hydraulically classified, and dried at high temperature after natural sedimentation. It has stable quality, good crystallization, high surface cleanliness, no Large particle, less fine particle content, concentrated particle size distribution, high grinding efficiency, suitable for various precision grinding processing, the surface of the processed workpiece is uniform and free of scratches.

Green silicon carbide spherical sand and micropowder are the products of secondary shaping by Raymond mill. The particles have less edges and corners, good hydrophilicity, high grinding efficiency and long working life.

Application of green silicon carbide:

1. Section sand. The green silicon carbide segment sand is produced by the Barmac sand making machine, with rounded particles. As a grinding medium, it can perfectly replace the high-priced zirconia balls. It has a perfect grinding effect in the ultra-fine powder grinding of green silicon carbide photovoltaic blades without affecting the Product content

2. Granular sand. Green silicon carbide grain size sand is mainly used for abrasive tool manufacturing and sandblasting media for surface treatment; abrasive tool manufacturing: resin grinding wheel, ultra-thin cutting disc, marble grinding wheel, diamond grinding disc, etc.; surface treatment: grinding carbide, hard and brittle Metal and non-metal materials - quartz glass, optical glass, piezoelectric ceramics, etc.

3. Micropowder. Green silicon carbide powder can be used for precision grinding of hard glass, slicing of single crystal silicon and polycrystalline silicon rods, precision grinding of single crystal silicon wafers, processing of superhard metals, processing of soft metals such as copper and copper alloys, and various resins processing of materials, etc.
