Yuav ua li cas txheeb xyuas qhov zoo dawb fused alumina abrasive

Qhov ceev kuj yog ib qho tseem ceeb qhia. Qhov ntom ntawmdawb fused alumina abrasivesyog muab faib ua cov ntim ntom ntom ntawm dawb corundum thiab qhov tseeb ntom ntom ntawm dawb fused alumina.

Cov ntim ntim ntawm dawb fused alumina abrasive yog 1.53-1.99 g/cm3. Lub ntim ntim ntawm cov abrasive nyob ntawm seb qhov luaj li cas ntawm cov nplej, qhov loj ntawm cov nplej, hom, hom qoob loo, thiab lwm yam. Feem ntau, coarse-grained abrasives muaj cov ntim ntau dua li cov nplua-grained abrasives. Lub ntim ntim ntawm cov khoom abrasive yog ntau dua li ntawm tus kheej particle loj.

Qhov tseeb qhov ceev ntawm dawb fused alumina abrasives: qhov ceev ntawm dawb fused alumina abrasive hais yog 3.95-4.0 g/cm3. Qhov tseeb qhov ceev ntawm abrasive yog hais txog qhov loj ntawm cov abrasive muaj nyob rau hauv chav tsev ntim (tsis suav nrog lub ntim ntawm qhov qhib).

Specializes nyob rau hauv zus tau tej cov dawb fused alumina abrasives nrog siab purity, zoo inherent sharpness, acid, thiab alkali corrosion kuj, kub kuj, thiab ruaj khov thermal kev ua tau zoo. Hardness yog me ntsis siab duaxim av fused alumina, toughness yog me ntsis qis, purity siab, thiab nws tus kheej ntse yog zoo. Muaj zog sib tsoo muaj peev xwm, tsis tshua muaj cua sov, ua haujlwm siab, acid, thiab alkali corrosion kuj, kub tsis kam, thiab thermal stability.
