Thaum graphite yog tshuaj kho, cov tshuaj tiv thaiv yog nqa tawm ib txhij ntawm ntug ntawm graphite nthuav thiab nyob rau hauv nruab nrab ntawm txheej. Yog hais tias cov graphite tsis huv thiab muaj impurities, lattice defects thiab dislocations yuav tshwm sim, uas ua rau lub expansion ntawm ntug cheeb tsam thiab qhov nce ntawm active chaw, uas yuav ua rau kom lub ntug cov tshuaj tiv thaiv. Txawm hais tias qhov no muaj txiaj ntsig zoo rau kev tsim cov ntug sib txuas, nws yuav cuam tshuam rau kev tsim cov graphite intercalation txuas ntxiv. Thiab cov txheej lattice raug rhuav tshem, uas ua rau cov lattice tsis meej thiab tsis sib xws, yog li ntawd qhov ceev thiab qhov tob ntawm cov tshuaj diffusion mus rau interlayer thiab tiam ntawm cov sib sib zog nqus intercalation tebchaw yog hindered thiab txwv, uas ntxiv cuam tshuam rau kev txhim kho ntawm expansion degree. Yog li ntawd, nws yuav tsum tau hais tias cov ntsiab lus ntawm graphite impurities yuav tsum nyob rau hauv lub cheeb tsam, tshwj xeeb tshaj yog cov granular impurities yuav tsum tsis muaj nyob, txwv tsis pub cov graphite nplai yuav raug txiav tawm thaum lub sij hawm nias, uas yuav txo tau qhov zoo ntawm cov khoom molded. Cov nram qab no Furuite graphite editor qhia tias purity ntawm graphite raw cov ntaub ntawv cuam tshuam cov khoom ntawm nthuav graphite:
Qhov loj me me ntawm graphite kuj muaj txiaj ntsig zoo rau kev tsim cov graphite nthuav dav. Qhov loj me me yog qhov loj, qhov tshwj xeeb ntawm thaj chaw me me, thiab thaj chaw koom nrog cov tshuaj tiv thaiv yog qhov me me. Ntawm qhov tsis sib xws, yog tias cov khoom me me, nws qhov chaw tshwj xeeb yog qhov loj, thiab thaj chaw rau kev koom nrog cov tshuaj tiv thaiv yog loj. Los ntawm kev txheeb xyuas qhov nyuaj ntawm cov tshuaj lom neeg invading, nws yog ib qho tseem ceeb uas cov khoom loj yuav ua rau cov nplais graphite tuab, thiab qhov sib txawv ntawm cov txheej yuav sib sib zog nqus, yog li nws nyuaj rau cov tshuaj nkag mus rau txhua txheej, thiab nws yog ntau dua. nyuaj rau kev sib kis hauv qhov khoob ntawm cov khaubncaws sab nraud povtseg kom ua rau cov khaubncaws sab nraud povtseg. Qhov no muaj txiaj ntsig zoo rau kev nthuav dav ntawm kev nthuav dav graphite. Yog hais tias cov graphite hais zoo dhau lawm, qhov tshwj xeeb ntawm qhov chaw yuav loj dhau, thiab cov tshuaj tiv thaiv ntug yuav ua rau muaj txiaj ntsig, uas tsis tsim nyog rau kev tsim cov khoom sib txuas. Yog li ntawd, graphite hais yuav tsum tsis txhob loj los yog me me heev.
Nyob rau hauv tib qhov chaw, nyob rau hauv kev sib raug zoo ntawm xoob ntom thiab particle loj ntawm nthuav graphite ua los ntawm graphite nrog sib txawv particle loj, qhov me dua qhov xoob ntom, qhov zoo dua cov nyhuv ntawm nthuav graphite. Txawm li cas los xij, hauv kev tsim khoom tiag tiag, nws tau pom tias qhov loj me ntawm cov graphite siv tau zoo dua los ntawm -30 mesh rau +100 mesh, uas yog qhov zoo tshaj plaws cov nyhuv.
Kev cuam tshuam ntawm graphite particle loj kuj tau xav txog tias qhov loj me me ntawm cov khoom xyaw yuav tsum tsis txhob dav dhau, uas yog, txoj kab uas hla qhov sib txawv ntawm qhov loj tshaj plaws thiab qhov me me yuav tsum tsis txhob loj dhau, thiab cov nyhuv ua haujlwm yuav yog. zoo dua yog hais tias cov particle loj muaj pes tsawg leeg yog uniform. Furuite graphite cov khoom yog tag nrho ua los ntawm ntuj graphite, thiab qhov zoo yog nruj me ntsis raws li cov txheej txheem ntau lawm. Cov khoom lag luam graphite ua tiav thiab tsim tau tau txais kev pom zoo los ntawm cov neeg siv khoom tshiab thiab qub tau ntau xyoo, thiab koj ib txwm txais tos sab laj thiab yuav khoom!
