绿碳化硅微粉W28中值粒径26-28um用于瓷砖磨石
绿碳化硅微粉W28，中值粒径26–28μm左右，晶体纯度高、自锐性强、磨削锋利耐磨，是瓷砖、磨石抛光打磨磨具例如菱苦土抛光磨块、碳化硅研磨油石、金刚石修整磨具等产品常用的精细磨料微粉。
产品硬度高、晶粒棱角规整，粒度分布均匀无超大颗粒，磨削切削力稳定，打磨过程不崩边、不刮花瓷砖釉面与磨石表面。化学性质稳定、耐酸碱、耐热性好，和树脂结合剂、陶瓷结合剂适配性优异，可用于制作瓷砖水磨磨块、抛光磨石、树脂磨片等制品。
适用于通体砖、釉面砖、仿古砖等各类瓷砖表面粗精磨、平整度修整，也可用于人造磨石、水磨石的成型打磨与表面精整，磨削效率高、出光效果好，批次粒度一致性强，适合大批量磨具磨石生产使用。
