Iphepha le-graphite yiphepha elikhethekile elicutshungulwa kusuka ku-graphite njengento eluhlaza. Lapho i-graphite isanda kumbiwa phansi, yayifana nje nezikali, futhi ithambile futhi ibizwa ngokuthi i-graphite yemvelo. Le graphite kumele icutshungulwe futhi icwengwe ukuze ibe wusizo. Okokuqala, cwilisa i-graphite yemvelo engxube ye-sulfuric acid egxilile kanye ne-nitric acid egxilile isikhathi esithile, bese uyikhipha, ugeze ngamanzi, uyomise, bese uyibeka esithandweni sokushisa esiphezulu ukuze sishiswe. Umhleli olandelayo we-Furuite graphite wethula izimfuneko zokukhiqizwa kwephepha le-graphite:
Ngenxa yokuthi ama-inlay phakathi kwama-graphite ahwamuka ngokushesha ngemva kokushiswa, futhi ngesikhathi esifanayo, umthamo we-graphite ukhula ngokushesha izikhathi eziningi noma ngisho namakhulu, ngakho-ke kutholakala uhlobo lwe-graphite ebanzi, olubizwa ngokuthi "i-graphite eyandisiwe". Kunemigodi eminingi (esele ngemva kokususwa kokufakwa ngaphakathi) ku-graphite eyandisiwe, enciphisa kakhulu ukuminyana kwe-graphite, okuyi-0.01-0.059 / cm3, isisindo esilula futhi esihle kakhulu ekushiseni ukushisa. Ngenxa yokuthi kunezimbobo eziningi, osayizi abahlukene, nokungalingani, zingaphambana lapho kusetshenziswa amandla angaphandle. Lokhu ukunamathela kwe-graphite enwetshiwe. Ngokwe-self-adhesion ye-graphite eyandisiwe, ingacutshungulwa ibe yiphepha le-graphite.
Ngakho-ke, imfuneko yokukhiqiza iphepha le-graphite iwukuba nesethi ephelele yemishini, okungukuthi, idivaysi yokulungisa i-graphite eyandisiwe kusuka ekucwilisweni, ukuhlanza, ukushisa, njll, lapho kukhona khona amanzi nomlilo. Kubaluleke ngokukhethekile; okwesibili umshini wokwenza amaphepha nokucindezela i-roller. Ukucindezela komugqa we-roller ecindezelayo akufanele kube phezulu kakhulu, ngaphandle kwalokho kuzothinta ukulingana namandla ephepha le-graphite, futhi uma ukucindezela komugqa kuncane kakhulu, akwamukeleki nakakhulu. Ngakho-ke, izimo zenqubo ezakhiwe kufanele zinembile, futhi iphepha le-graphite lesaba umswakama, futhi iphepha eliqediwe kufanele lihlanganiswe emaphaketheni okufaka umswakama futhi ligcinwe kahle.
