Tsawg Hlau Cov Ntsiab Lus Dawb Fused Aluminium Oxide

Dawb fused aluminium oxide yog cov khoom siv purity abrasive uas feem ntau siv rau kev lag luam, xws li blasting, sib tsoo, thiab polishing. Nws yog tsim los ntawm melting high-purity alumina nyob rau hauv ib tug hluav taws xob arc rauv thiab ces txias nws maj mam tsim ib tug crystalline qauv.

Cov ntsiab lus tsis tshua muaj hlau dawb fused aluminium oxide yog ib qho txawv ntawm dawb fused aluminium oxide uas muaj cov ntsiab lus hlau tsawg heev. Hlau yog ib qho impurity nyob rau hauv ntau cov ntaub ntawv abrasive thiab tuaj yeem ua rau tsis muaj xim thiab staining ntawm qhov chaw raug kho. Cov ntsiab lus tsis tshua muaj hlau dawb fused aluminium oxide yog li nyiam rau cov ntawv thov uas tsis muaj xim lossis staining tsis tau, xws li hauv kev tsim cov khoom siv high-end ceramics, iav, thiab electronics.

Kev tsim cov hlau tsis muaj cov ntsiab lus dawb fused aluminium oxide yuav tsum ceev faj tswj cov txheej txheem melting thiab siv cov khoom siv high-purity raw. Cov khoom uas tau tshwm sim muaj qib siab ntawm purity, nrog cov ntsiab lus hlau feem ntau hauv qab 0.05 feem pua.
