黑碳化硅30# Black SiC Grit 的特點(diǎn)和用途


       黑碳化硅30#的冶煉設(shè)備是大型電阻爐,原材料是石英砂、石油焦和其他輔料。經(jīng)過(guò)高溫冶煉的碳化硅從外部到內(nèi)部分為不同等級(jí),外部通常是碳化硅含量較低的碳化硅,可作為冶金材料,爐芯部分的一級(jí)碳化硅含量高,是生產(chǎn)研磨級(jí)碳化硅的材料。黑碳化硅30#是大理石蝕刻、金剛砂地坪、噴砂的*想材料,磨削力強(qiáng),研磨效率優(yōu)異。

The smelting equipment for black silicon carbide 30 # is a large resistance furnace, and the raw materials are quartz sand, petroleum coke, and other auxiliary materials. After high-temperature smelting, silicon carbide is divided into different grades from the outside to the inside. The outside is usually silicon carbide with low silicon carbide content, which can be used as a metallurgical material. The primary silicon carbide content in the furnace core is high, making it a material for producing grinding grade silicon carbide. Black silicon carbide 30 # is an ideal material for marble etching, diamond sand flooring, and sandblasting, with strong grinding force and excellent grinding efficiency.
