Precision Casting Advanced Refractory Khoom Dawb Corundum 280 Mesh 320 Mesh
Product Description
Dawb fused alumina hmoov yog ua los ntawm high-purity low-sodium alumina hmoov los ntawm melting ntawm kub, txias crystallization, thiab ces crushing.Cov dawb fused aluminium oxide hmoov grit yog nyob rau hauv kev tswj nruj kom cov lis loj faib thiab zoo ib yam.
Lub grain loj faib ntawm cov dawb fused alumina hmoov yog nqaim.Tom qab shaping ua, siab purity dawb corundum hmoov muaj tag nrho cov nplej, ntse npoo thiab fab, siab sib tsoo efficiency, siab polishing brightness.Kev sib tsoo efficiency ntau dua li cov mos abrasives xws li silica.
