Iphepha le-graphite liyiphepha elikhethekile elicutshungulwa nge-graphite njengezinto zokusetshenziswa. Lapho i-graphite isanda kumbiwa emhlabathini, yayifana nezikali, futhi yayithambile futhi yayibizwa ngokuthi i-graphite yemvelo. Le graphite kumele icutshungulwe futhi ihlanzwe ukuze ibe wusizo. Okokuqala, cwilisa i-graphite yemvelo engxubeni ye-sulfuric acid egxilile kanye ne-nitric acid egxilile isikhathi esithile, bese uyikhipha, uyihlanze ngamanzi, uyomise, bese uyibeka esithandweni sokushisa okuphezulu ukuze ishiswe. Umhleli we-graphite we-Furuite olandelayo wethula izidingo zokukhiqizwa kwephepha le-graphite:
Ngenxa yokuthi ama-inlays phakathi kwama-graphite ayanyamalala ngokushesha ngemva kokushiswa, futhi ngesikhathi esifanayo, umthamo we-graphite ukhula ngokushesha ngamanani noma ngisho namakhulu ezikhathi, ngakho-ke kutholakala uhlobo lwe-graphite ebanzi, olubizwa ngokuthi “i-expanded graphite”. Kunezimbobo eziningi (ezisele ngemva kokususwa kwama-inlays) ku-graphite enwetshiwe, okunciphisa kakhulu ubukhulu be-graphite, obungu-0.01-0.059/cm3, obulula ngesisindo futhi obuhle kakhulu ekushiseni. Ngenxa yokuthi kunezimbobo eziningi, osayizi abahlukene, kanye nokungalingani, zingahlanganiswa lapho kusetshenziswa amandla angaphandle. Lokhu ukuzinamathelisa kwe-graphite enwetshiwe. Ngokusho kokuzinamathelisa kwe-graphite enwetshiwe, ingacutshungulwa ibe yiphepha le-graphite.
Ngakho-ke, imfuneko yokukhiqizwa kwephepha le-graphite ukuba nesethi ephelele yemishini, okungukuthi, idivayisi yokulungisa i-graphite enwetshiwe kusukela ekucwilisweni, ekuhlanzweni, ekushisweni, njll., lapho kukhona amanzi nomlilo. Kubaluleke kakhulu; okwesibili umshini wokwenza iphepha nokucindezela i-roller. Ingcindezi eqondile ye-roller yokucindezela akufanele ibe phezulu kakhulu, ngaphandle kwalokho izothinta ukufana namandla ephepha le-graphite, futhi uma ingcindezi eqondile incane kakhulu, ayamukeleki nakakhulu. Ngakho-ke, izimo zenqubo eziklanyiwe kumele zibe zinembile, futhi iphepha le-graphite lesaba umswakama, futhi iphepha eliqediwe kumele lifakwe emaphaketheni angangeni umswakama futhi ligcinwe kahle.
