SG abrasive yog polycrystalline alumina abrasive nrog submicron crystalline qauv.Nws muab kev sib tsoo ntau dua li cov pa fused alumina abrasives, vim tias nws cov ntug txiav yog fractured microscopically thiab superior txiav muaj peev xwm khaws cia hauv qhov chaw thiab cylindrical sib tsoo.Sib tsoo log ua los ntawm ceramic abrasive nrog muaj lub zog ntau dua thiab lub neej ntev dua, uas yog 5-10 npaug tshaj qhov sib tsoo lub log ua los ntawm corundum.Its high-performing seeded gel ceramic alumina thiab friable aluminium oxide abrasive blend kav peb mus rau tsib zaug ntev dua. tshaj li cov pa txhuas oxide log, thiab nws tus kheej-sharpening abrasive maximizes ntse npoo ntawm cov cuab yeej thiab tuag.
