Iphepha le-graphite liyiphepha elikhethekile elenziwe nge-graphite. Lapho i-graphite isanda kumbiwa emhlabathini, yayifana nezikali, futhi yayibizwa ngokuthi i-graphite yemvelo. Lolu hlobo lwe-graphite kumele luphathwe futhi lucwengisiswe ngaphambi kokuba lusetshenziswe. Okokuqala, i-graphite yemvelo ifakwa esixazululweni esixubile se-sulfuric acid egxilile kanye ne-nitric acid egxilile isikhathi esithile, bese igezwa ngamanzi acwebile bese ibhobozwa, bese ifakwa esithandweni sokushisa okuphezulu ukuze ishiswe. Umhleli we-graphite we-Furuite olandelayo wethula imibandela yokukhiqizaiphepha le-graphite:
Ngenxa yokuthi ukuhlangana phakathi kwe-graphite kuyaphela ngokushesha ngemva kokushisa, ngesikhathi esifanayo, umthamo we-graphite wanda ngokushesha ngamanani noma ngisho namakhulu ezikhathi, ngakho-ke kutholakala uhlobo lwe-graphite ebanzi, ebizwa ngokuthi “i-graphite evuvukile”. Kunezimbobo eziningi endaweni evuvukile.i-graphite(kushiywe ngemuva kokususwa kwe-inlay), okunciphisa kakhulu ubuningi bokupakisha kwe-graphite kube ngu-0.01 ~ 0.059/cm3, ngesisindo esincane kanye nokushisa okuhle kakhulu. Ngenxa yokuthi kunezimbobo eziningi ezinobukhulu obuhlukene kanye nezikhukhula, zingaxhunyaniswa komunye nomunye ngamandla angaphandle, okuyi-self-adhesion ye-graphite enwetshiwe. Ngokusho kwalokhu kuzinamathisela kwe-graphite enwetshiwe, kungacutshungulwa kube yiphepha le-graphite.
Ngakho-ke, imfuneko yokukhiqizwa kwephepha le-graphite ukuba nesethi ephelele yemishini, okungukuthi, idivayisi yokulungisa i-graphite enwetshiwe ekucwilisweni, ekuhlanzweni nasekushisweni, lapho kukhona amanzi nomlilo, okungaholela ekuqhumeni, ngakho-ke ukukhiqizwa okuphephile kubaluleke kakhulu; Okwesibili, imishini yokwenza amaphepha kanye nokucindezela ama-roller, ingcindezi eqondile yokucindezela ama-roller akufanele ibe phezulu kakhulu, ngaphandle kwalokho izothinta ukufana kanye namandla ephepha le-graphite, kanti ingcindezi eqondile incane kakhulu, okuyinto engenakwenzeka nakakhulu. Ngakho-ke, izimo zenqubo kumele zibe zinembile, futhii-graphitIphepha le-e liyasaba umswakama. Iphepha eliqediwe kufanele libe yiphakheji elingangeni umswakama, khumbula ukuthi lingangeni manzi futhi ligcinwe kahle.
