石榴石滤料又名“玉砂”或“天然金刚砂”，具有较强的硬度和很好的耐酸耐碱性，是一种岛状结构的铝（钙）硅酸盐，它色多优美，目前，经高纯磁选出的有灰、红、绿、白等多种染色体，是国外当前新开发的立体喷墙涂料，还是玻壳厂唯一能做彩壳喷砂耐磨料，由于它内部化学分子多，化学稳定性好等特点。故被当作新型耐磨净水滤料。

理化性能分析

Appearance: dark, red and green granule, made by the processing of island aluminum (calcium) structure silicate minerals. Currently, there are gray, red, green, white and other colures by the manufacture of high-purity magnetic.

Features: Strong durability, high melting point, large proportion and stable performance.

Uses: a newly developed three-dimensional wall spray paint and is the only material made wear-resistant materials of a glass - shell factory. Because of its many internal chemical molecules, chemical stability and other characteristics, it has been making a new wear-resistant water treatment filter.
