黑色碳化硅粗砂 F12–F24
黑色碳化硅F12–F24粗粒度，SiC含量≥98%，粒形锋锐自锐性好，单位面积去除量大。适用于钢结构喷砂除锈、铸件清理、工业地坪防滑铺设及重型磨削砂轮制造等场合。
// 主要特性
- Large grain geometry delivers high material removal rates in heavy-duty blasting
- Self-sharpening fracture pattern reduces glazing and extends service life
- Consistent sieve classification per FEPA F-grade standard for process repeatability
- High friability enables controlled breakdown and continuous fresh cutting edge exposure
