Daim ntawv graphite yog daim ntawv tshwj xeeb ua los ntawm graphite. Thaum graphite nyuam qhuav raug khawb tawm hauv av, nws zoo li cov nplai, thiab nws hu ua graphite ntuj. Hom graphite no yuav tsum tau kho thiab ua kom zoo ua ntej nws siv tau. Ua ntej, cov graphite ntuj raug tsau rau hauv cov tshuaj sib xyaw ntawm cov kua qaub sulfuric thiab cov kua qaub nitric acid rau ib lub sijhawm, tom qab ntawd ntxuav nrog dej ntshiab thiab tho, thiab tom qab ntawd muab tso rau hauv lub cub tawg kub rau kev hlawv. Cov kws kho graphite Furuite hauv qab no qhia txog cov xwm txheej ua ntej rau kev tsim khoomdaim ntawv graphite:
Vim tias qhov inlay ntawm graphite evaporates sai tom qab cua sov, tib lub sijhawm, qhov ntim ntawm graphite nthuav dav sai los ntawm kaum ob lossis txawm tias ntau pua zaus, yog li ib hom graphite dav tau txais, uas hu ua "swollen graphite". Muaj ntau qhov nyob rau hauv qhov ographite(tso tseg tom qab tshem cov inlay), uas ua rau cov graphite ntim khoom tsawg dua 0.01 ~ 0.059/cm3, nrog rau qhov hnyav sib dua thiab rwb thaiv cua sov zoo heev. Vim tias muaj ntau qhov chaw uas muaj ntau qhov loj thiab qhov tsis sib xws, lawv tuaj yeem sib txuas ua ke los ntawm lub zog sab nraud, uas yog qhov kev nplaum ntawm cov graphite nthuav dav. Raws li qhov kev nplaum ntawm cov graphite nthuav dav no, nws tuaj yeem ua tiav rau hauv daim ntawv graphite.
Yog li ntawd, qhov yuav tsum tau ua ua ntej rau kev tsim cov ntawv graphite yog kom muaj cov khoom siv tiav, uas yog, lub cuab yeej rau kev npaj cov graphite nthuav dav los ntawm kev tsau, ntxuav thiab hlawv, uas muaj dej thiab hluav taws, uas yuav ua rau tawg, yog li kev tsim khoom zoo yog qhov tseem ceeb heev; Qhov thib ob, cov tshuab ua ntawv thiab cov tshuab nias cov menyuam, qhov siab ntawm cov menyuam nias yuav tsum tsis txhob siab dhau, txwv tsis pub nws yuav cuam tshuam rau qhov sib xws thiab lub zog ntawm cov ntawv graphite, thiab qhov siab me dhau, uas tsis yooj yim sua. Yog li ntawd, cov txheej txheem yuav tsum raug, thiabgraphiteDaim ntawv e-ntawv ntshai cov dej noo. Daim ntawv tiav lawm yuav tsum yog cov ntim khoom uas tsis muaj dej noo, nco ntsoov kom tsis txhob ntub dej thiab khaws cia kom zoo.
