绿碳化硅2500# 的性能特点和用途


       绿碳化硅2500#对标绿色碳化硅W7,其中值粒径为6.0-7.3um,适用于精细研磨和抛光。研磨对象广泛，包括石英玻璃、光学玻璃、超硬合金、玉石宝石等材料。绿碳化硅本身具有卓越的磨削力，研磨效率和去除率高。经过化学处理和水洗工艺生产的绿碳化硅微粉颗粒范围窄，可以得到均匀的研磨表面。

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.
