Alumina ceramics yog ib hom engineering ceramics, thiab kev siv niaj hnub ntawm cov khoom siv ceramic txawv heev. Alumina ceramics kuj tseem hu ua cov khoom siv ceramics uas tiv taus hnav, vim nws muaj kev tiv taus hnav zoo heev, tiv taus corrosion, tiv taus kub siab, yog li nws siv dav hauv hlau, thee, mining, cement, tshuaj lom neeg thiab lwm yam lag luam, yog qhov kev xaiv zoo rau kev tiv taus hnav hauv kev lag luam.
Cov txheej txheem ntawm kev ua alumina ceramics feem ntau yog muab faib ua ntau kauj ruam: kev npaj hmoov, nias, sintering.
Yuav kom ua tau cov khoom siv ceramic uas tiv taus hnav nrog kev ua tau zoo, nws yog ib qho tsim nyog los xaiv cov hmoov alumina zoo, uas nws qhov loj me feem ntau yog 1μm lossis tsawg dua. Thaum lub sijhawm ua hmoov, yuav tsum ntxiv cov khoom sib txawv los npaj cov hmoov nrog cov khoom sib txawv.
Alumina ceramics muaj peev xwm tsim tau ntau txoj hauv kev. Cov txheej txheem siv feem ntau yog kev nias qhuav molding, grouting molding, extrusion, isostatic pressing molding, txhaj tshuaj molding, dov molding, kub pressing, gel molding, thiab lwm yam. Kev muab molding yog qhov tseem ceeb rau kev npaj cov khoom siv ceramics uas tiv taus kev hnav zoo. Feem ntau, alumina ceramics ua los ntawm kev nias qhuav thiab isostatic pressing txheej txheem muaj qhov nyuaj thiab hnav tsis kam siab dua.
Kev sintering alumina ceramics kuj yog ib kauj ruam tseem ceeb heev. Ntawm lawv, kev tswj hwm qhov kub sintering yog qhov tseem ceeb, txiav txim siab qhov ceev, qauv thiab lub neej ua haujlwm ntawm cov ceramic.
Txhua kauj ruam ntawm kev tsim khoomalumina ceramicsyuav tsum tau kev tswj hwm thiab kev tshawb pom los ntawm cov kws tshaj lij, txhawm rau kom tau txais cov khoom siv ceramics uas tiv taus kev hnav zoo heev.
