Faka i-graphiteisetshenziswa kabanzi embonini, kodwa isidingo se-flake graphite sihlukile ezimbonini ezahlukene, ngakho-ke i-flake graphite idinga izindlela ezihlukene zokuhlanza. Umhleli olandelayo we-Furuite graphite uzochaza ukuthi yiziphi izindlela zokuhlanzai-flake graphiteine:
1. Indlela ye-Hydrofluoric acid.
Izinzuzo eziyinhloko ze-hydrofluoric acid indlela yokusebenza kahle kokususwa kokungcola, izinga eliphezulu lemikhiqizo, ithonya elincane ekusebenzeni kwemikhiqizo ye-graphite kanye nokusetshenziswa kwamandla okuphansi. Ububi ukuthi i-hydrofluoric acid inobuthi obukhulu futhi iyagqwala, futhi izinyathelo eziqinile zokuvikela ukuphepha kufanele zithathwe enqubweni yokukhiqiza.Izidingo eziqinile zemishini nazo ziholela ekwenyukeni kwezindleko. Ngaphezu kwalokho, amanzi angcolile akhiqizwa indlela ye-hydrofluoric acid anobuthi kakhulu futhi ayagqwalisa, futhi adinga ukwelashwa okuqinile ngaphambi kokuba akhishwe. Ukutshalwa kwezimali ekuvikelweni kwemvelo nakho kunciphisa kakhulu izinzuzo zezindleko eziphansi zendlela ye-hydrofluoric acid.
2, indlela eyisisekelo yokuhlanza i-asidi.
Okuqukethwe kwekhabhoni ye-graphite ehlanjululwe ngendlela ye-alkaline acid ingafinyelela ngaphezu kuka-99%, enezici zokutshalwa kwezimali okuphansi kwesikhathi esisodwa, izinga lomkhiqizo ophezulu kanye nokuzivumelanisa nezimo eziqinile. Ngaphezu kwalokho, inezinzuzo zemishini evamile kanye nokuguquguquka okunamandla. Indlela ye-asidi eyisisekelo iyindlela esetshenziswa kakhulu eChina. Ukungalungi kwayo ukusetshenziswa kwamandla amakhulu, isikhathi eside sokuphendula, ukulahlekelwa okukhulu kwegraphite kanye nokungcoliswa kwamanzi angcolile okubi kakhulu.
3. Indlela yokugcoba nge-chlorine.
Izinga lokushisa eliphansi lokugazinga kanye nokusetshenziswa kwe-chlorine encane yendlela yokuthosa ye-chlorine kunciphisa kakhulu izindleko zokukhiqizai-graphite. Ngesikhathi esifanayo, okuqukethwe kwekhabhoni yemikhiqizo ye-graphite kulingana naleyo yokwelashwa kwe-hydrofluoric acid, futhi izinga lokutholwa kwendlela yokugazinga i-chlorination liphezulu. Kodwa-ke, ngenxa yokuthi i-chlorine inobuthi futhi iyagqwala, idinga ukusebenza kwemishini ephezulu futhi idinga ukubekwa uphawu okuqinile, futhi igesi yomsila kufanele iphathwe kahle, ngakho Ngokwezinga elithile, ikhawulela ukuthandwa kwayo nokusetshenziswa kwayo.
4. Indlela yokushisa ephezulu.
Inzuzo enkulu yendlela yokushisa okuphezulu ukuthi okuqukethwe kwekhabhoni komkhiqizo kuphezulu kakhulu, okungafinyelela ngaphezu kwama-99.995%. Okubi ukuthi isithando somlilo esishisa kakhulu kufanele siklanywe futhi sakhiwe ngokukhethekile, izinto zokusebenza ziyabiza, futhi kukhona ukutshalwa kwezimali okuningi kwesibili. Ngaphezu kwalokho, ukusetshenziswa kwamandla kuphezulu, futhi isikweletu sikagesi esiphezulu sandisa izindleko zokukhiqiza. Ngaphezu kwalokho, izimo ezinzima zokukhiqiza nazo zenza ububanzi bokusebenza kwale ndlela bube buncane kakhulu. Kuphela kwezokuvikela kazwelonke, i-aerospace nezinye izikhathi ezinezidingo ezikhethekile ekuhlanzekeni kwemikhiqizo ye-graphite, le ndlela ibhekwa njengokukhiqizwa kwenqwaba encane.i-graphite, futhi ngeke kwaziswe embonini.
