Alumina Ceramic Daim Hlau yog qhov zoo tshaj plaws hluav taws xob insulator thiab tuaj yeem ua haujlwm zoo txog li 1,650 degree C. Cov khoom siv alumina ceramic (Al2O3 ceramic) yog ib qho kev siv hluav taws xob uas siv ntau tshaj plaws. Tsis tas li, alumina phaj yog superior nyuaj thiab mas xeb-resistant. Nyob rau hauv cov khoom siv dav siv, cov phiajcim alumina (Al2O3) tau siv, xws li hluav taws xob& cov khoom siv hluav taws xob, hnav cov hlua khi, sintering setters thiab sensors.

UNIPRETEC muab Al2O3 tej hub ua los ntawm Al2O3 purities sib txawv (GG gt; 90%), suav nrog 92% Al2O3, 95% Al2O3, 96% Al2O3 thiab 99% Al2O3, feem ntau qib thov yog 95% thiab 99%.

Cov kab ntau ntawm cov txheej txheem ntau lawm, xws li qhuav nias, CIP, kab xev casting thiab txhaj tshuaj molding, tuaj yeem siv los ua Al2O3 phaj. Los ntawm kev sib tsoo tiaj thiab polishing, txiav laser thiab ntau tus txheej txheem, ntau yam duab ua haujlwm thiab siab precision tuaj yeem ua tiav.

Al203 ceramic daim hlau tsim los ntawm UNIPRETEC yog qhov haum rau cov txheej txheem metallizing thiaj li tsim cov khoom lag luam uas, hauv kev ua haujlwm tom qab, nws yooj yim rau kev zawm nrog ntau yam. Txhawm rau kom txaus siab rau cov ntawv thov nyuaj tshaj plaws, UNIPRETEC ib txwm mob siab rau nws tus kheej hauv R& D ntawm kev tsim cov paib ceramic alumina daim hlau.
