綠碳化硅46#的技術(shù)指標(biāo)


       綠碳化硅46#是一種比剛玉和天然金剛砂硬度高的磨料，它由原材料硅砂、石油焦、食鹽等材料經(jīng)過(guò)高溫熔煉即艾奇遜法冶煉而來(lái)。綠碳化硅比重低，導(dǎo)熱系數(shù)高、研磨能力強(qiáng)，適用于石英玻璃、陶瓷、鈦合金、大理石等材料的研磨。

Green silicon carbide 46 # is an abrasive with higher hardness than corundum and natural diamond sand. It is produced by high-temperature smelting of raw materials such as silica sand, petroleum coke, and table salt using the Acheson method. Green silicon carbide has a low specific gravity, high thermal conductivity, and strong grinding ability, making it suitable for grinding materials such as quartz glass, ceramics, titanium alloys, and marble.
