Precision Casting Advanced Refractory Khoom Dawb Corundum 280 Mesh 320 Mesh
Kev piav qhia txog khoom
Cov hmoov alumina dawb fused yog ua los ntawm cov hmoov alumina uas muaj cov sodium tsawg thiab muaj cov khoom qab zib ntau los ntawm kev yaj ntawm qhov kub siab, txias cov khoom siv crystallization, thiab tom qab ntawd zom. Cov hmoov alumina dawb fused oxide grit raug tswj hwm nruj kom khaws cov noob sib faib thiab cov tsos zoo ib yam.
Qhov faib ntawm cov hmoov dawb fused alumina yog nqaim. Tom qab ua tiav cov duab, cov hmoov dawb corundum purity siab muaj cov noob puv, cov npoo ntse thiab cov ces kaum, kev sib tsoo zoo, thiab qhov ci ntsa iab siab. Kev sib tsoo zoo dua li cov khoom siv abrasives mos xws li silica.
