Cov txheej txheem ntxuav kom huv ntawm cov flake graphite thiab lawv cov txiaj ntsig thiab qhov tsis zoo

Cov nplai graphiteyog siv dav hauv kev lag luam, tab sis qhov kev thov rau flake graphite yog txawv hauv ntau yam lag luam, yog li flake graphite xav tau ntau txoj kev ntxuav. Tus kws kho graphite Furuite hauv qab no yuav piav qhia txog cov txheej txheem ntxuav dab tsigraphite flakemuaj:

1. Txoj kev siv hydrofluoric acid.
Qhov zoo tshaj plaws ntawm txoj kev hydrofluoric acid yog qhov ua tau zoo ntawm kev tshem tawm cov khoom tsis huv, cov khoom zoo, tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm cov khoom graphite thiab kev siv hluav taws xob tsawg. Qhov tsis zoo yog tias hydrofluoric acid muaj tshuaj lom thiab xeb heev, thiab yuav tsum muaj kev tiv thaiv kev nyab xeeb nruj hauv cov txheej txheem tsim khoom. Cov kev cai nruj rau cov khoom siv kuj ua rau tus nqi nce ntxiv. Tsis tas li ntawd, cov dej khib nyiab uas tsim los ntawm txoj kev hydrofluoric acid muaj tshuaj lom thiab xeb heev, thiab nws xav tau kev kho mob nruj ua ntej nws tuaj yeem tso tawm. Kev nqis peev hauv kev tiv thaiv ib puag ncig kuj txo qhov zoo ntawm tus nqi qis ntawm txoj kev hydrofluoric acid.
2, txoj kev ntxuav cov kua qaub yooj yim.
Cov pa roj carbon ntawm graphite uas tau ntxuav los ntawm alkaline acid tuaj yeem ncav cuag ntau dua 99%, uas muaj cov yam ntxwv ntawm kev nqis peev ib zaug tsawg, qib khoom siab thiab kev hloov pauv tau zoo. Ntxiv mus, nws muaj qhov zoo ntawm cov khoom siv niaj hnub thiab muaj zog versatility. Txoj kev acid yooj yim yog txoj kev siv dav tshaj plaws hauv Suav teb. Nws qhov tsis zoo yog kev siv hluav taws xob ntau, lub sijhawm teb ntev, kev poob graphite ntau thiab kev ua qias tuaj ntawm cov dej khib nyiab loj.
3. Txoj kev ci chlorination.
Qhov kub qis thiab kev siv tshuaj chlorine me me ntawm txoj kev chlorination roasting ua rau cov nqi tsim khoom tsawg duagraphiteTib lub sijhawm, cov pa roj carbon ntawm cov khoom graphite yog sib npaug rau cov kev kho hydrofluoric acid, thiab qhov rov qab los ntawm chlorination roasting txoj kev yog siab dua. Txawm li cas los xij, vim tias chlorine yog lom thiab corrosive, nws xav tau kev ua haujlwm ntawm cov khoom siv siab thiab xav tau kev sib khi nruj, thiab cov roj tail yuav tsum tau kho kom zoo, yog li qee qhov, nws txwv nws qhov nrov thiab daim ntawv thov.
4. Txoj kev kub siab.
Qhov zoo tshaj plaws ntawm txoj kev kub siab yog tias cov pa roj carbon ntawm cov khoom yog siab heev, uas tuaj yeem ncav cuag siab dua 99.995%. Qhov tsis zoo yog tias lub cub tawg kub siab yuav tsum tau tsim tshwj xeeb thiab tsim, cov khoom siv kim heev, thiab muaj ntau qhov kev nqis peev thib ob. Tsis tas li ntawd, kev siv hluav taws xob siab, thiab daim nqi hluav taws xob siab ua rau tus nqi tsim khoom nce ntxiv. Ntxiv mus, cov xwm txheej tsim khoom hnyav kuj ua rau daim ntawv thov ntawm txoj kev no txwv heev. Tsuas yog hauv kev tiv thaiv lub tebchaws, aerospace thiab lwm lub sijhawm nrog cov kev cai tshwj xeeb ntawm kev huv ntawm cov khoom graphite, txoj kev no raug txiav txim siab rau kev tsim khoom me me ntawmgraphite, thiab nws tsis tuaj yeem nrov npe hauv kev lag luam.
