Iphepha le-graphite liyiphepha elikhethekile elenziwe nge-graphite. Lapho i-graphite isanda kumbiwa phansi, yayifana nezikali, futhi yayibizwa ngokuthi i-graphite yemvelo. Lolu hlobo lwe-graphite kufanele luphathwe futhi lucwengisiswe ngaphambi kokuba lusetshenziswe. Okokuqala, i-graphite yemvelo ifakwe kwisisombululo esixubile se-sulfuric acid egxilile kanye ne-nitric acid egxilile isikhathi esithile, bese igezwa ngamanzi ahlanzekile futhi inesithukuthezi, bese ifakwa esithandweni sokushisa esiphezulu ukuze sishiswe. Umhleli olandelayo we-Furuite graphite wethula imibandela yokukhiqizaiphepha le-graphite:
Ngenxa yokuthi i-inlay phakathi kwe-graphite iyahwamuka ngokushesha ngemva kokushisa, ngesikhathi esifanayo, umthamo we-graphite ukhula ngokushesha izikhathi eziningi noma ngisho namakhulu, ngakho-ke kutholakala uhlobo lwe-graphite ebanzi, olubizwa ngokuthi "i-graphite evuvukele". Kunezimbobo eziningi endaweni evuvukelei-graphite(kwesokunxele ngemva kokukhishwa kwe-inlay), okunciphisa kakhulu ukuminyana kokupakisha kwe-graphite ku-0.01 ~ 0.059 / cm3, ngesisindo esincane kanye nokushisa okuhle kakhulu. Ngenxa yokuthi kunemigodi eminingi enosayizi abahlukene kanye ne-scraggy, ingaxhunyaniswa ne-crisscross ngamandla angaphandle, okuyi-self-adhesion ye-graphite enwetshiwe. Ngokwalokhu kunamathela kwe-graphite eyandisiwe, ingacutshungulwa ibe yiphepha le-graphite.
Ngakho-ke, imfuneko yokukhiqizwa kwephepha le-graphite iwukuba nesethi ephelele yemishini, okungukuthi, idivaysi yokulungiselela i-graphite eyandisiwe kusuka ekucwilisweni, ekuhlanzeni nasekushiseni, lapho kukhona amanzi nomlilo, okungase kuholele ekuqhumeni, ukukhiqizwa okuphephile kubaluleke kakhulu; Okwesibili, i-papermaking kanye nemishini yokucindezela i-roller, ukucindezela okuqondile kokucindezela kwe-roller akufanele kube phezulu kakhulu, ngaphandle kwalokho kuzothinta ukufana namandla ephepha le-graphite, futhi ukucindezela komugqa kuncane kakhulu, okungenakwenzeka nakakhulu. Ngakho-ke, izimo zenqubo kufanele zinembile, futhiigraphitiphepha esaba umswakama. Iphepha eliqediwe kufanele libe ukupakishwa kokuvikela umswakama, khumbula ukuthi lingangeni manzi futhi lilondolozwe kahle.
