Iphepha le-Graphite iphepha elikhethekile elenziwe ngegrafu. Lapho i-graphite yavele yavunjwa emhlabathini, ibinjengesikali nje, futhi yabizwa ngokuthi i-Graphite yemvelo. Lolu hlobo lwegrafu kumele luphathwe futhi luhlanjululwe ngaphambi kokuthi lusetshenziswe. Okokuqala, i-graphite yemvelo ifakwe okhambini oluxubile lwe-sulfuric acid ehlanganisiwe kanye ne-nitric acid isikhathi eside, bese igezwa ngamanzi acwebile futhi inesithukuthezi, bese ifakwa esithandweni sokushisa okushisa kakhulu. Umhleli we-graphite olandelayo wethula imivimbo yokukhiqizaIphepha le-Graphite:
Ngoba i-inlay phakathi kwe-graphite ivele ngokushesha ngemuva kokushisa, ngasikhathi sinye, umthamo we-graphite unwebeka ngokushesha ngamahlandla amaningi noma ama-graphite amaningi, okubizwa ngokuthi "i-graphite ebanzi". Kunezimbobo eziningi ekuvuvukenii-graphite(Kwesobunxele ngemuva kokususwa kwe-inlay), okunciphisa kakhulu ukupakishwa kwabantu be-graphite kuya ku-0.01 ~ 0.059 / cm3, ngesisindo esikhanyayo kanye nokufakelwa okuhle kakhulu. Ngoba kunezinto eziningi ezinosayizi ohlukile kanye nama-scraggy, zingaxhunyaniswa komunye nomunye crisscross ngamandla angaphandle, okukuzinamathela kokuzinamathela kwe-graphite enwetshiwe. Ngokusho nalokhu kokuzinamathela kwegrafu enwetshiwe, kungacutshungulwa kube yiphepha le-graphite.
Ngakho-ke, imfuneko yokukhiqizwa kwephepha le-graphite kufanele ibe nesethi ephelele yemishini, okungukuthi, idivaysi yokulungiselela i-graphiod enwetshiwe ekufakweni, ekuhlanzeni nasekushiseni, okunjalo, okungcono kakhulu ukuqhuma, ngakho-ke ukukhiqizwa okuphephile kubaluleke kakhulu; Okwesibili, ama-papermaking kanye ne-roller acindezela imishini, ingcindezi eqondile yokucindezela kwe-roller akufanele ibe phezulu kakhulu, ngaphandle kwalokho izothinta ukufana namandla ephepha le-graphite, futhi kungenakwenzeka kakhulu. Ngakho-ke, izimo zenqubo kumele zinembile, futhiihluzoIphepha lesaba umswakama. Iphepha eliqediwe kufanele libe ukupakishwa komswakama-ubufakazi, khumbula ukuthi lingangeni manzi futhi ligcinwe kahle.
