Cov khoom siv raw ntawmdawb aluminium oxidemicro hmoov yog dawb fused alumina, uas yog ua los ntawm high-zoo txhuas oxide hmoov. Lub ntsiab impurities nyob rau hauv bauxite yog txo los ntawm kev txo smelting txoj kev, yog li tau cov xim av corundum uas yog crystallized thiab muaj ib tug zoo raws li qhov yuav tsum tau thiab ib tug alumina cov ntsiab lus ntawm ntau tshaj 95%. Cov khoom yog xim dawb, nyuaj thiab nkig tshaj xim av corundum, muaj zog txiav, zoo tshuaj stability, thiab zoo rwb thaiv tsev. Nws yog tsim rau ib co advanced polishing thiab refractory ntaub ntawv.
Hlau xuab zeb los ntawm kev rho tawm los ntawm cov pas dej thiab cov pas dej. Tom qab tshwj xeeb ntau lawm, nws dhau los ua cov khoom zoo. Nws yog characterized los ntawm ntug thiab siab hardness. Nws tuaj yeem siv rau hauv kev kho cua sov, cov khoom siv refractory, xeb tshem tawm, metallurgy, thiab xuab zeb tu. Hauv kev lag luam muaj feem xyuam xws li hlau xuab zeb thiab dawb aluminium oxide, muaj qhov sib xws ntawm cov khoom siv raw. Ntawm cov ntaub ntawv raw ntawm dawb fused alumina, bauxite tso nyiaj rau qhov kev faib ua feem ntau tshaj plaws, thiab kev ua haujlwm ntawm dawb fused alumina tom qab ntau lawm kuj yog tus cwj pwm los ntawm kev hnav tsis kam thiab siab siab.
Cov yam ntxwv thiab thaj tsam ntawm daim ntawv thov ntawm dawb aluminium oxide xuab zeb yog tshwj xeeb zoo ib yam li cov xuab zeb hlau. Yog li vim li cas ho tsis siv hlau xuab zeb hauv cov ntaub ntawv dawb fused alumina? Qhov tseeb, cov txheej txheem ntau lawm ntawm dawb fused alumina yuav tsum tau kub-kub forging. Qhov kev ua tau zoo ntawm cov xuab zeb hlau tsis ruaj khov ntawm qhov kub thiab txias, thiab cov xim dawb aluminium oxide kuj yuav raug rau cov txheej txheem kub kub calcination tom qab siv. Rau ib puag ncig uas yuav tsum tau muaj kev tiv thaiv corrosion, nws yog ntau hlau xuab zeb siv tsis tau lawm. Raws li peb txhua tus paub, hlau yuav corrode tom qab lub sijhawm ntev ntawm oxidation, uas yog qhov phem heev rau kev siv tom qab.
