Iphepha legraphite liphepha elikhethekileyo elenziwe ngegraphite. Xa i<em>graphite yayisandul’ ukugrunjwa emhlabeni, yayifana nje nezikali, yaye yayibizwa ngokuba yi<em>graphite yendalo. Olu hlobo lwegraphite kufuneka lunyangwe kwaye lucocwe phambi kokuba lusetyenziswe. Okokuqala, i-graphite yendalo ixutywe kwisisombululo esixubileyo se-sulfuric acid egxininisiweyo kunye ne-nitric acid egxininisiweyo ixesha elithile, emva koko ihlanjwe ngamanzi acacileyo kwaye idikwe, ize ifakwe kwisithando somlilo esiphezulu sokutshisa. Lo mhleli ulandelayo weFuruite graphite wazisa imiqathango yokuvelisaiphepha legraphite:
Ngenxa yokuba i-inlay phakathi kwegraphite iphuphuma ngokukhawuleza emva kokufudumeza, kwangaxeshanye, umthamo wegraphite ukhula ngokukhawuleza ngamaninzi okanye namakhulu amaxesha, ngoko ke kufunyenwe uhlobo lwegraphite ebanzi, ebizwa ngokuba yi "graphite edumbileyo". Mininzi imingxuma kwindawo edumbileyoigraphite(ekhohlo emva kokuba i-inlay isusiwe), okunciphisa kakhulu ukupakisha ukuxinana kwegraphite ukuya kwi-0.01 ~ 0.059 / cm3, kunye nobunzima obulula kunye nokushisa okuphezulu. Ngenxa yokuba kukho imingxunya emininzi enobukhulu obahlukeneyo kunye ne-scraggy, inokudityaniswa enye kwenye i-crisscross ngamandla angaphandle, okuzincamathela kwegraphite eyandisiweyo. Ngokwale-self-adhesion ye-graphite eyandisiweyo, inokucutshungulwa ibe yiphepha legraphite.
Ngoko ke, imfuneko yokuveliswa kwephepha legraphite kukuba neseti epheleleyo yezixhobo, oko kukuthi, isixhobo sokulungiselela igraphite eyandisiweyo ukusuka ekucwiliseni, ukucoca kunye nokutshisa, apho kukho amanzi kunye nomlilo, okungakhokelela ekuqhumeni, ngoko. imveliso ekhuselekileyo ibaluleke kakhulu; Okwesibini, i-papermaking kunye ne-roller pressing machines, i-linear pressure ye-roller pressing ayifanele ibe phezulu kakhulu, ngaphandle koko iya kuchaphazela ukulingana kunye namandla ephepha legraphite, kwaye uxinzelelo lomgca luncinci kakhulu, olungenakwenzeka ngakumbi. Ngoko ke, iimeko zenkqubo kufuneka zichaneke, kwayeigraphitiphepha eyoyika ukufuma. Iphepha eligqityiweyo kufuneka libe yi-package-proof package, khumbula ukuba ungangeni manzi kwaye ugcinwe ngokufanelekileyo.
