Kev hloov ntawm alumina activated yog ib hom kev ntxeem tau, siab dispersion ntawm cov khoom tsis zoo, muaj ntau qhov chaw deg, nws cov qhov dej ntxau tau muaj cov nyhuv catalytic ntawm cov yam ntxwv uas yuav tsum tau muaj, xws li adsorption, kev ua haujlwm deg, zoo thermal stability, thiab lwm yam. , yog li nws yog dav siv raws li tshuaj lom neeg cov tshuaj tiv thaiv thiab catalyst cab kuj, siv nyob rau hauv kev siv yuav tsum tau them sai sai rau hauv qab cov ntsiab lus :
1. Ncua lub sij hawm soaking ntawm cov khoom siv lim hauv cov kua qaub, thiab tshem tawm cov kua qoob loo ntawm alkali ntawm cov khoom lim kom ntau.
2. Cuam kom ntev lub sij hawm sib cuag ntawm cov ntaub ntawv lim dej alumina thiab muaj zog alkali txhuam kom tshiab, thiab nce tus nqi ntawm cov tshuaj fluorine.
3. Siv cov defluoridation tank tsis tau kho tus nqi ntawm cov dej mus ntev, uas tsis tsuas saturates lim khoom ua ntej, tab sis kuj cuam tshuam cov peev txheej adsorption tom qab kev tsim rov qab.
4. Muaj peev txheej adsorption ntawm cov khoom siv rau cov tshuaj fluorine tsawg dua obviously.
5. Thawj thawj zaug ntawm cov khoom siv lim tiav lawm.
6, kho cov txheej txheem pliav kom tsis pub dhau ntawm qhov teev (6.5-7.0), tsis yog tsuas muaj peev xwm txhim kho tau cov dej zoo, tiam sis kuj ntev lub neej ntawm cov khoom siv alumina lim dej, zoo dua qhov ua haujlwm ntawm cov khoom siv fluorine.
