Abrasive belts, emery cloths, sandpaper, etc. coated with abrasives and resin grinding wheels and other consolidated abrasives, grinding sharp, heating rate is very low, grinding ratio is high, and less adhesion when used; The sintered abrasive made has the characteristics of no network cracks and no rust spots after firing.
F sand is used for resin, ceramic grinding wheel; P sand is used for the production of coated abrasives, such as emery cloth sandpaper.
