Graphite ntawv yog ib daim ntawv tshwj xeeb ua los ntawm graphite. Thaum graphite tsuas yog khawb hauv av, nws yog xws li nplai, thiab nws tau hu ua cov duab ci. Qhov no hom ntawm graphite yuav tsum tau kho thiab ua kom zoo ua ntej nws siv tau. Ua ntej, lub ntuj graphite yog soaked hauv kev sib xyaw ntawm cov sulfuric acid thiab bored nrog ntshiab dej thiab dhuav rau hauv lub tshuab hluav taws kub kom hlawv. Cov hauv qab no ua plaub ntsuab txhim kho qhia txog qhov ua ntej rau kev tsimGraphite ntawv:
Vim hais tias cov inlay ntawm graphite evapector sai sai tom qab cua sov, tib lub sijhawm, cov khoom siv dav dav, uas yog hu ua "o swollment". Muaj ntau lub qhov nyob rau hauv cov o onpaim(sab laug tom qab inlay raug tshem tawm cov ntim ntom ntom ntawm graphite rau 0.059 / CM3, nrog lub teeb yuag thiab kev ua kom sov zoo. Vim tias muaj ntau cov kab ke nrog cov sib txawv thiab cov sib txawv, lawv tuaj yeem cuam tshuam nrog txhua lwm qhov sib zog ntawm kev sib zog sab nraud, uas yog tus kheej-nplaum ntawm kev nthuav qhia graphite. Raws li cov lus qhia ntawm tus kheej ntawm kev nthuav dav graphite, nws tuaj yeem ua tiav rau hauv daim ntawv graphite.
Yog li ntawd, qhov yuavtsum tau kawm uantej rau cov ntawv tsim yog kom npaj cov khoom siv thiab hluav taws, uas yuav ua rau muaj cov khoom tawg thiab hluav taws, uas yuav ua rau muaj kev sib tw tshwj xeeb; Qhov thib ob, papermaking thiab cov menyuam nias tshuab, kab kev siab ntawm cov ntawv nias, tsis yog nws yuav cuam tshuam rau cov kab mob graphite, thiab cov kab kev siab yog qhov tseem ceeb heev, uas yog qhov tseem ceeb tshaj plaws. Yog li ntawd, cov txheej txheem cov txheej txheem yuav tsum muaj tseeb, thiabdaim ntawvE daim ntawv yog ntshai noo. Cov ntawv tiav lawm yuav tsum yog cov dej noo-pov thawj ntim, nco ntsoov tias yuav tsum tau dej thiab muaj txiaj ntsig.
