Iphepha le-Graphite iphepha elikhethekile elilungiswe kusuka kugrafu njengento eluhlaza. Lapho i-graphite yavele yavunjwa emhlabathini, ibinjengesikali nje, futhi yayithambile futhi yabizwa ngokuthi i-graphite yemvelo. Le graphite kumele icutshungulwe futhi ihlanzwe ukuze ibe wusizo. Okokuqala, cwilisa i-graphite yemvelo engxenyeni ye-sulfuric acid ehlanganisiwe ne-nitric acid isikhathi esithile, bese uyikhipha, uyihlanze ngamanzi, bese uyibeka esithandweni sokushisa okushisa kakhulu. Umhleli we-graphite olandelayo wethula izimfanelo zokukhiqizwa kwephepha le-graphite:
Ngoba izimbotshana eziphakathi kwama-graphites zivele ngokushesha ngemuva kokufudumala, futhi ngasikhathi sinye, ivolumu ye-graphite inwebeka ngokushesha ngamaphizu noma amaphilisi amahlandla abanzi, okubizwa ngokuthi yi-graphite ebanzi ". Kunemikhondo eminingi (eshiywe ngemuva kokuthi ama-inlays asusiwe) kwi-graphite enwetshiwe, ehlisa kakhulu ubukhulu be-graphite, okungu-0.01-0.059 / cm3, okungcono kakhulu ekuvikeleni. Ngoba kunezimbobo eziningi, osayizi abahlukahlukene, nokungalingani, zingaba yi-criss nomunye lapho kufakwa amandla angaphandle. Lokhu ukunamathela kokuzimela kwegrafu enwetshiwe. Ngokusho kokuzinamathela kwesithombe esinwetshiwe, singacutshungulwa sibe yiphepha le-graphite.
Ngakho-ke, imfuneko yokukhiqizwa kwephepha le-graphite kufanele ibe nesethi ephelele yemishini, okungukuthi, ithuluzi lokulungiselela i-graphite enwetshiwe kusuka ekubhaleni, ukuhlanza, ukushiswa, njll. Kubaluleke kakhulu; Okwesibili ngumshini we-roller wapaper. Ingcindezi eqondile ye-roller ecindezelayo akufanele ibe phezulu kakhulu, ngaphandle kwalokho izothinta ubusika namandla ephepheni le-graphite, futhi uma ingcindezi eqondile incane kakhulu, ingamukeleki kakhulu. Ngakho-ke, izimo zenqubo ezenziwe kahle kufanele zibe zinembile, futhi iphepha le-graphite liyasaba umswakama, futhi iphepha eliqediwe kufanele lifakwe kumaphakeji abufakazi bokuswakama futhi ligcinwe kahle.
