綠碳化硅2500# 的性能特點(diǎn)和用途


       綠碳化硅2500#對標(biāo)綠色碳化硅W7,其中值粒徑為6.0-7.3um,適用于精細(xì)研磨和拋光。研磨對象廣泛，包括石英玻璃、光學(xué)玻璃、超硬合金、玉石寶石等材料。綠碳化硅本身具有卓越的磨削力，研磨效率和去除率高。經(jīng)過化學(xué)處理和水洗工藝生產(chǎn)的綠碳化硅微粉顆粒范圍窄，可以得到均勻的研磨表面。

Green silicon carbide 2500 # corresponds to green silicon carbide W7, with a particle size range of 6.0-7.3um, suitable for fine grinding and polishing. Grinding objects are diverse, including quartz glass, optical glass, superhard alloys, jade, gemstones, and other materials. Green silicon carbide itself has excellent grinding force, high grinding efficiency and removal rate. The green silicon carbide micro powder produced by chemical treatment and water washing process has a narrow particle range and can obtain a uniform grinding surface.
