Abrasive Hardness Taw Qhia

Lub hardness ntawm abrasives mas yog nyob ntawm tus nqi ntawm cov binder ntxiv thiab qhov ceev ntawm abrasives, abrasive hais yog ib qho yooj yim mus poob, qhia tias tsawg abrasive hardness; Ntawm qhov tsis sib xws, nws txhais tau tias siab hardness. Cov qib hardness feem ntau muab faib ua super mos, mos, nruab nrab mos, nruab nrab nyuaj, nyuaj thiab super nyuaj xya qib, los ntawm cov qib no kuj tuaj yeem muab faib ua ntau theem me. Cov txheej txheem siv ntau dua los txiav txim siab qhov nyuaj ntawm cov cuab yeej abrasive yog txhais tes lub khob hliav qab, cov txheej txheem lub khob hliav qab, Rockwell hardness tester method thiab sandblasting hardness tester method.Qhov hardness ntawm abrasives sib haum rau nws cov dynamic elastic modulus, uas yog conducive rau kev siv suab. txoj kev los txiav txim qhov dynamic elastic modulus ntawm abrasives los qhia qhov hardness ntawm abrasives. Nyob rau hauv txoj kev sib tsoo, yog tias cov khoom hardness ntawm qhov sib tsoo yog siab, cov cuab yeej abrasive uas tsis tshua muaj hardness feem ntau yog xaiv; Ntawm qhov tsis sib xws, cov cuab yeej abrasive nrog siab hardness raug xaiv.
