Cov graphite nthuav tawm tau tsim los ntawm ob txheej txheem: tshuaj lom neeg thiab hluav taws xob. Ob qhov txheej txheem sib txawv ntxiv rau txheej txheem oxidation, deacidification, ntxuav dej, lub cev qhuav dej, ziab thiab lwm yam txheej txheem yog tib yam. Qhov zoo ntawm cov khoom lag luam ntawm cov tuam txhab lag luam feem ntau siv cov txheej txheem tshuaj tuaj yeem ncav cuag qhov ntsuas tau teev tseg hauv GB10688-89 "nthuav dav cov duab hluav taws xob" tus qauv, thiab ua tau raws li cov khoom siv xav tau rau kev tsim cov khoom siv tau yooj yim graphite thiab xa cov qauv xa tawm.
Tab sis kev tsim khoom tshwj xeeb xav tau ntawm cov khoom tsis tshua muaj neeg hloov pauv (≤10%), cov ntsiab lus sulfur tsawg (≤2%) ntawm cov khoom lag luam nyuaj, cov txheej txheem tsim khoom tsis dhau. Ntxiv dag zog rau kev tswj hwm kev kawm, kawm cov txheej txheem sib xyaw ua tib zoo, ua kom muaj kev sib raug zoo ntawm cov txheej txheem txheej txheem thiab cov khoom ua tau zoo, thiab tsim cov khoom ruaj khov nthuav dav tau zoo yog cov yuam sij txhawm rau txhim kho cov khoom lag luam tom ntej. Qingdao Furuite Graphite cov ntsiab lus: cov txheej txheem hluav taws xob tsis muaj lwm yam oxidants, lub ntuj flake graphite thiab cov pab cuam anode ua ke ua ib qho anode chamber tsau rau hauv cov tshuaj sulfuric acid electrolyte, los ntawm qhov ncaj qha tam sim no lossis mem tes tam sim no, oxidation tom qab qee lub sijhawm tshem tawm, tom qab ntxuav thiab ziab. yog nthuav graphite. Qhov loj tshaj plaws ntawm tus qauv no yog qhov tshuaj tiv thaiv qib ntawm graphite thiab qhov ntsuas qhov ua tau zoo ntawm cov khoom tuaj yeem tswj tau los ntawm kev kho cov ntsuas hluav taws xob thiab lub sijhawm tshuaj tiv thaiv, nrog kev ua qias tuaj me me, tus nqi qis, ruaj khov thiab ua tau zoo. Nws yog qhov nrawm los daws qhov teeb meem sib xyaw, txhim kho kev ua tau zoo thiab txo qis kev siv hluav taws xob hauv cov txheej txheem sib xyaw.
Tom qab deacidification los ntawm ob txoj hauv kev saum toj no, qhov sib piv ntawm sulfuric acid ntub dej thiab adsorption ntawm graphite interlamellar cov tebchaw tseem yog li 1: 1, kev siv cov neeg sawv cev sib xyaw yog loj, thiab ntxuav cov dej haus thiab tso dej tawm ntau. Thiab feem ntau cov chaw tsim khoom tsis tau daws qhov teeb meem ntawm kev kho cov dej khib nyiab, nyob rau hauv lub xeev ntawm kev tso tawm ib puag ncig, ib puag ncig muaj kuab paug loj, yuav txwv txoj kev txhim kho kev lag luam.
