Cov txheej txheem ntau lawm ntawm cov graphite nthuav dav

Tom qab cov graphite graphite no tau kho kub heev ntawm qhov kub thiab txias, cov nplai ua cov cab zoo li no, thiab cov ntim tuaj yeem nthuav 100-400 zaug. Qhov kev hloov kho Graphite no tseem tuav tau cov khoom ntawm lub ntuj graphite, muaj qhov nthuav dav zoo, yog xoob thiab muaj qhov kub thiab txias thiab kub thiab txias. Ntau yam, tuaj yeem nyob nruab nrab -200 ~ 3000 ℃, tshuaj lom neeg muaj zog nyob rau hauv cov roj av, hauv hluav taws xob, cov khoom lag luam, cov khoom lag luam, cov khoom lag luam muaj ntau cov kev siv. Cov qauv hauv qab no ntawm cov plaub hau Graphite yuav coj koj kom nkag siab txog cov txheej txheem ntau lawm:
1. Ultrasonic oxidation txoj kev los ua kom yooj yim graphite.
Nyob rau hauv cov txheej txheem ntawm kev npaj graphite, ultrasonic kev co yog ua rau ntawm anodized electrolyte, thiab lub sij hawm ntawm ultrasonic kev coration yog tib yam li ntawm anodization. Txij li thaum qhov kev co ntawm cov hluav taws xob ultrasonic yog los ntawm kev ua kom puv rau cov cathode ntawm catode thiab qhov ceev ntawm Anodic oxidation tau nrawm thiab lub sijhawm oxidation yog luv;
2. Lub txiv qaub molten ntsev ua kom muaj peev xwm piav tau yooj yim.
Sib tov ob peb ntxig nrog graphite thiab cua sov los ua daim ntawv yooj yim graphite;
3. Cov roj-theem diffusion txoj kev yog siv los ua kom yooj yim graphite.
Cov duab thiab cov khoom siv sib cuam tshuam tau coj los ntawm cov khoom siv flake uas tau nkag los ntawm cov khoom siv kub uas muaj qhov sib txawv, yog li cov khoom siv me me, yog li npaj tau yooj yim graphite. Tus naj npawb ntawm cov khaubncaws sab nraud ntawm graphite tsim los ntawm cov qauv no tuaj yeem tswj tau, tab sis nws tus nqi tsim khoom yog siab;
4. Cov txheej txheem tshuaj lom neeg ua rau yooj yim graphite.
Thawj cov khoom siv raw rau kev npaj yog cov tshuaj pleev xim zoo li cov pa roj hmab xws li muaj cov tshuaj lom neeg cov tshuaj lom neeg Cov kauj ruam dav dav ntawm kev npaj yog raws li hauv qab no: Tshuaj Flake Acid ntawm cov txheej txheem sib txawv, tom qab lub cev qhuav dej, lub cev qhuav dej ntawm 60 ° C;
5. Electrochemical Zus tau cov khoom tawg yooj yim.
Graphite hmoov yog kho nyob rau hauv ib tug muaj zog acid electrolyte los ua kom yooj yim graphy, hydrolyzed, ntxuav thiab qhuav. Raws li cov acid muaj zog, sulfuric acid los yog nitric acid yog siv xwb. Cov khoom tawg tau txais los ntawm hom no muaj cov ntsiab lus sulfur tsawg.
