Wa dawb txhuas oxide sib tsoo cov log
Cov log dawb txhuas txhuas kuj hu ua cov alumina dawb, dawb corundum sib tsoo cov log, wA sib tsoo cov log. Nws yog qhov kev sib tsoo ntau tshaj plaws.
Dawb Aluminium oxide yog daim ntawv kho dua tshiab ntawm cov tshuaj txhuas oxide muaj ntau dua 99% ntshiab alumina. Lub siab purity ntawm cov abrasive no tsis tsuas yog tso cai rau nws cov yam ntxwv dawb xim dawb, tab sis kuj qiv nws nrog nws cov cuab yeej ntawm kev sib cais siab. Lub hardness ntawm cov abrasive no yog li cas los xij li cas los ntawm cov xim av txhuas oxide (1700 - 2000 kg / mm kg / hli Qhov no cov abrasive dawb tshwj xeeb thiab txias thiab sib tsoo cov yam ntxwv tawv, tshwj xeeb yog cov hlau nyuaj lossis qib siab hauv ntau yam kev sib tsoo ua haujlwm.
