Semi-friable fused alumina yog ib hom tshiab ntawm qib siab tshaj plaws fused alumina hauv Suav teb uas sib txuas cov txiaj ntsig ntawm xim av thiab dawb fused alumina, piv txwv li lub toughness ntawm brownfused alumina thiab sharpness ntawm dawb fussed alumina. Nrog rau qhov tshwj xeeb sib tsoo thiab txiav cov nyhuv, nws tuaj yeem siv rau kev tsim cov khoom siv qib siab ceramic, cob sib tsoo cov cuab yeej thiab cov cuab yeej coated abrasive.

Semi-friable fused alumina yog ib hom tshiab ntawm qib siab tshaj plaws fused alumina hauv Suav teb uas sib txuas cov txiaj ntsig ntawm xim av thiab dawb fused alumina, piv txwv li lub toughness ntawm brownfused alumina thiab sharpness ntawm dawb fussed alumina. Nrog rau qhov tshwj xeeb sib tsoo thiab txiav cov nyhuv, nws tuaj yeem siv rau kev tsim cov khoom siv qib siab ceramic, cob sib tsoo cov cuab yeej thiab cov cuab yeej coated abrasive. Cov khoom sib txuas abrasive tsim nrog nws muab lub zog siab dua, zoo sharpness thiab retentiveness. Thaum ua cov khoom ua haujlwm nyob rau hauv tib yam kev mob, nws ua kom pom qhov zoo ntawm qhov zoo, ua haujlwm zoo dua thiab ua haujlwm zoo dua ntawm cov cuab yeej sib tsoo dua li xim av, dawb, chrome thiab monocrystalline fused alumina. Piv nrog xim av fused alumina sib tsoo log. Tom qab txhua qhov kev sib tsoo ntawm cov cuab yeej sib tsoo, tus naj npawb ntawm cov khoom ua haujlwm nws cov txheej txheem tuaj yeem ua ob npaug. Thiab piv nrog dawb fused alumina thiab monocrystalline fused alumina. Nws tuaj yeem nce los ntawm 10% mus rau 30% lossis ncav cuag qhov siv tib yam. Siv rau kev sib tsoo ntxhib, nws tuaj yeem txhim kho kev ua haujlwm zoo thiab siv rau kev sib tsoo kom raug nws tuaj yeem txhim kho qhov zoo ntawm cov khoom ua haujlwm. Nws muaj feem xyuam rau cov hlau tsis tu ncua, cov kabmob steel, stainlesssteels thiab cov cuab yeej hlau rau kev siv, tshwj xeeb tshaj yog cov hlau tsis muaj steel thiab cov khoom ua haujlwm uas yooj yim deformed lossis hlawv los ntawm overheat. Nws kuj tseem tuaj yeem siv los ua cov hlau alloy tshwj xeeb nrog cov ntsiab lus qis ntawm chrome, vanadium, molybdenum, tungsten, cobalt, qee cov castiron, txhua yam hlau tsis muaj hlau, xws li txhuas alloy uas muaj tooj liab, nickeland magnesium, tooj liab uas muaj leej faj thiab zinc, magnesium alloy uas muaj aluminium thiab zinc, thiab lwm yam.
Semi-friable Fused Alumina kuj yog qhov zoo thiab qib siab tshaj plaws refractory teeb meem.
