Thaum graphite raug kho los ntawm tshuaj lom neeg, cov tshuaj tiv thaiv yuav ua tiav tib lub sijhawm ntawm ntug ntawm graphite nthuav dav thiab hauv nruab nrab ntawm txheej. Yog tias graphite tsis huv thiab muaj cov khoom tsis huv, cov teeb meem lattice thiab dislocations yuav tshwm sim, ua rau thaj tsam ntug nthuav dav thiab nce ntawm cov chaw nquag, uas yuav ua rau cov tshuaj tiv thaiv ntug sai dua. Txawm hais tias qhov no pab tau rau kev tsim cov tshuaj sib xyaw, nws yuav cuam tshuam rau kev tsim cov tshuaj sib xyaw graphite nthuav dav. Thiab cov txheej txheem lattice raug rhuav tshem, uas ua rau cov lattice tsis sib xws thiab tsis xwm yeem, yog li qhov ceev thiab qhov tob ntawm cov tshuaj sib kis mus rau interlayer thiab tiam ntawm cov tshuaj sib xyaw sib xyaw tob raug cuam tshuam thiab txwv, uas cuam tshuam ntxiv rau kev txhim kho qib nthuav dav. Yog li ntawd, nws yog qhov yuav tsum tau ua kom cov ntsiab lus ntawm graphite impurities yuav tsum nyob hauv qhov ntau yam teev tseg, tshwj xeeb tshaj yog cov khoom tsis huv granular yuav tsum tsis txhob muaj, txwv tsis pub cov nplai graphite yuav raug txiav tawm thaum lub sijhawm nias, uas yuav txo qhov zoo ntawm cov ntaub ntawv molded. Tus kws kho graphite Furuite hauv qab no qhia tias qhov huv ntawm cov ntaub ntawv graphite raw cuam tshuam rau cov khoom ntawm graphite nthuav dav:
Qhov loj ntawm cov khoom me me ntawm graphite kuj muaj feem cuam tshuam loj rau kev tsim cov graphite nthuav dav. Qhov loj ntawm cov khoom loj, qhov chaw tshwj xeeb yog me, thiab thaj chaw koom nrog kev tshuaj lom neeg yog me me. Ntawm qhov tsis sib xws, yog tias cov khoom me me, nws thaj chaw tshwj xeeb yog loj, thiab thaj chaw rau kev koom nrog kev tshuaj lom neeg yog loj. Los ntawm kev tshuaj xyuas qhov nyuaj ntawm cov tshuaj lom neeg nkag mus, nws yog qhov tsis zam uas cov khoom loj yuav ua rau cov nplai graphite tuab, thiab qhov sib txawv ntawm cov khaubncaws sab nraud povtseg yuav tob, yog li nws nyuaj rau cov tshuaj nkag mus rau hauv txhua txheej, thiab nws nyuaj dua rau kev nthuav dav hauv qhov sib txawv ntawm cov khaubncaws sab nraud povtseg kom ua rau cov khaubncaws sab nraud povtseg tob. Qhov no muaj feem cuam tshuam loj rau qib kev nthuav dav ntawm graphite nthuav dav. Yog tias cov khoom graphite zoo dhau, thaj chaw tshwj xeeb yuav loj dhau, thiab qhov kev cuam tshuam ntug yuav tseem ceeb, uas tsis zoo rau kev tsim cov tshuaj sib xyaw. Yog li ntawd, cov khoom graphite yuav tsum tsis txhob loj dhau lossis me dhau.
Nyob rau hauv tib qho chaw, nyob rau hauv kev sib raug zoo ntawm qhov ceev xoob thiab qhov loj ntawm cov graphite nthuav dav ua los ntawm graphite nrog cov qhov loj me sib txawv, qhov me dua qhov ceev xoob, qhov zoo dua qhov cuam tshuam ntawm graphite nthuav dav. Txawm li cas los xij, hauv kev tsim khoom tiag tiag, nws tau qhia tias qhov ntau thiab tsawg ntawm cov graphite siv yog qhov zoo tshaj plaws los ntawm -30 mesh txog +100 mesh, uas yog qhov cuam tshuam zoo tshaj plaws.
Qhov cuam tshuam ntawm qhov loj ntawm graphite particle kuj tseem pom tseeb tias qhov sib xyaw ua ke ntawm cov khoom xyaw yuav tsum tsis txhob dav dhau, uas yog, qhov sib txawv ntawm qhov loj tshaj plaws thiab qhov me tshaj plaws yuav tsum tsis txhob loj dhau, thiab cov txiaj ntsig ua tiav yuav zoo dua yog tias qhov sib xyaw ua ke ntawm qhov loj me yog sib xws. Cov khoom lag luam graphite Furuite yog ua los ntawm graphite ntuj, thiab qhov zoo yog qhov yuav tsum tau ua hauv cov txheej txheem ntau lawm. Cov khoom lag luam graphite ua tiav thiab tsim tawm tau txais kev nyiam los ntawm cov neeg siv khoom tshiab thiab qub tau ntau xyoo, thiab koj ib txwm txais tos los sab laj thiab yuav khoom!
