Green silicon carbide F80# for sandblasting Knife slot
Why green silicon carbide is used for knife slot sandblasting？
Green sic is widely used for knife slot sandblasting because it is extremely hard, sharp, and chemically stable. It efficiently removes burrs, oxide, and machining residue from high‑speed steel and carbide tools.
Its high thermal conductivity prevents overheating and deformation of precision knife slots.
The abrasive has good self‑sharpening ability, maintaining stable cleaning performance.
It produces a uniform surface finish that improves coating adhesion and chip removal.
Meanwhile, it causes less damage to cutting edges compared with other abrasives.
Description:
Green silicon carbide is a green translucent hexagonal non-metallic mineral product made from petroleum coke and high-quality silica as the main raw materials, with salt as an additive, and is produced through 2200° high-temperature smelting in a resistance furnace. Then we will get green sic ingot. After crushing, screening, moisture acid washing, at last we will get different sizes of green sic powder.
