Garnet sand is called a natural corundum, strong hardness and good acid and alkali resistance,it is a kind of aluminum silicate, it has more beautiful color, at present, the high purity magnetic separation of the grey, red, green, white wait for a variety of chromosome, is the development of new foreign current three-dimensional spray wall paint, color casing or only can do sandblasting abrasive resistance, due to its internal chemical molecules,chemistry stability is good wait for a characteristic. so it as a new type water purification filter material.
Description
Garnet abrasive materials belong to silicate minerals, carefully screened through hydraulic, mechanical processing, grading and other screening methods made of glass products mainly used for grinding products, industrial rust and water cutting, etc.
