Yuav ua li cas txheeb xyuas qhov zoo ntawm corundum abrasive

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

Cov ntim ntim ntawm dawb corundum abrasive yog 1.53-1.99 g / cm3. Lub ntim ntim ntawm cov abrasive yog 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 cov dawb corundum abrasives: qhov ceev ntawm dawb corundum abrasive hais yog 3.95-4.0 g/cm3. Qhov tseeb 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 corundum abrasives nrog siab purity, zoo inherent sharpness, acid thiab alkali corrosion kuj, siab kub kuj thiab ruaj khov thermal ua haujlwm. Hardness yog me ntsis siab dua xim av corundum, toughness yog me ntsis qis, purity siab, 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, zoo thermal stability.
