Alumina Silica Crucible Rau Hmoov Calcining
1. Taw qhia ntawm crucibles
Crucibles ntawm alumina thiab silica cov ntsiab lus tau siv dav hauv kev lag luam tshuaj rau calcining ntau yam hmoov. Cov crucibles uas peb muaj peev xwm muab tau muaj ntau qhov ntau thiab tsawg, cov duab thiab cov khoom siv raw uas tuaj yeem ua tau raws li qhov xav tau ntawm peb cov neeg siv khoom.
2. TDS ntawm crucibles ntawm ntau yam khoom siv raw

Thov muab sau tseg: Cov ntaub ntawv nthuav tawm yog cov txiaj ntsig nruab nrab. Lawv yuav raug hloov pauv ib txwm thiab yuav tsum tsis txhob siv rau kev lees paub lossis lub hom phiaj tshwj xeeb. Tsis tas li, txij li peb muaj peb tus kheej lab thiab lub Hoobkas, peb tuaj yeem kho peb cov khoom kom tau raws li cov neeg siv khoom xav tau.
3. Khoom Zoo
(1) siab tawv;
(2) siab thermal poob siab kuj;
(3) zoo hnav tsis kam;
(4) siab tshuaj lom inertness.
4. Daim ntawv thov khoom
(1) cov khoom siv hlau lossis tsis yog hlau;
(2) tshuaj xyuas cov khoom hauv chav kuaj;
(3) lub ntiaj teb tsis tshua muaj los yog cov hlau muaj txiaj ntsig zoo tshwj xeeb los ntawm cov qib siab alumina crucibles.
