Kev ua kom huv ntawm cov graphite feem ntau suav nrog cov hauv qab no:
Alkali acid purification method: Txoj kev no muaj cov yam ntxwv ntawm kev nqis peev tsawg ib zaug, qib khoom siab, thiab cov txheej txheem muaj zog adaptability. Nws qhov tsis zoo yog kev siv lub zog siab, lub sij hawm ntev cov tshuaj tiv thaiv, loj graphite poob thiab cov dej khib nyiab loj.
Hydrofluoric acid txoj kev: Txoj kev no muaj kev tshem tawm impurity siab, qib khoom siab thiab kev siv hluav taws xob tsawg, tab sis nws muaj cov kev cai nruj ntawm cov khoom siv thiab cov nqi siab. Tsis tas li ntawd, hydrofluoric acid yog cov tshuaj lom thiab corrosive, thiab yuav tsum muaj kev tiv thaiv nruj heev.
chlorination roasting txoj kev: Txoj kev no muaj qhov kub thiab txias, tsis muaj chlorine noj, tsis tshua muaj nqi thiab siab rov qab. Txawm li cas los xij, nws qhov tsis zoo yog tias cov tshuaj chlorine muaj tshuaj lom, muaj cov kev xav tau siab rau kev ua haujlwm ntawm cov cuab yeej siv, thiab yuav tsum muaj kev sib khi nruj thiab kev kho cov roj av.
Cov txheej txheem kub kub: Cov khoom ntawm txoj kev no muaj cov ntsiab lus carbon siab heev, uas tuaj yeem ncav cuag ntau dua 99.995%, tab sis cov cuab yeej siv kim, kev nqis peev loj, thiab kev siv hluav taws xob siab. Nws yog tsim rau me me batch ntau lawm nyob rau hauv tshwj xeeb zaus xws li lub teb chaws tiv thaiv thiab aerospace.
Flotation method : Flotation yog ib qho thev naus laus zis uas siv cov yam ntxwv ntab ntab ntawm graphite cais graphite los ntawm lwm yam minerals los ntawm ntau theem ntawm kev sib tsoo thiab kev txheeb xyuas. Qhov zoo ntawm flotation yog cov cuab yeej siv yooj yim, kev siv hluav taws xob tsawg, tus nqi qis, thiab tuaj yeem txhim kho qhov purity thiab zoo ntawm graphite.
Txhua txoj hauv kev no muaj nws qhov zoo thiab qhov tsis zoo, thiab xaiv txoj kev zoo yuav tsum tau txiav txim siab raws li cov kev xav tau tshwj xeeb thiab cov nqi.
