Ngemva kokuba i-graphite enwebekayo iphathwe ngokushesha lapho izinga lokushisa liphezulu, isikali siba njenge-worm, futhi ivolumu inganda izikhathi eziyi-100-400. Le graphite enwebekayo isagcina izakhiwo ze-graphite yemvelo, inokwanda okuhle, ikhululekile futhi inezimbobo, futhi imelana nokushisa ngaphansi kwezimo zokuvimbela umoya-mpilo. Ibanga elibanzi, lingaba phakathi kuka-200 ~ 3000 ℃, izakhiwo zamakhemikhali zizinzile ngaphansi kwezimo zokushisa eziphakeme, ukucindezela okuphezulu noma imisebe, ekuvalelweni okunamandla nokungaguquki kwezimboni ze-petroleum, amakhemikhali, kagesi, zezindiza, zezimoto, zemikhumbi nezinsimbi Kunezinhlobo eziningi zezicelo. Abahleli abalandelayo be-Furuit Graphite bazokuqondisa izindlela ezivamile zokukhiqiza ze-graphite enwebekayo:
1. Indlela ye-Ultrasonic oxidation yokwenza i-graphite enwebekayo.
Enkambisweni yokulungiselela i-graphite enwebekayo, ukudlidliza kwe-ultrasonic kwenziwa ku-electrolyte e-anodized, futhi isikhathi sokudlidliza kwe-ultrasonic sifana nesokudlidliza. Njengoba ukudlidliza kwe-electrolyte yigagasi le-ultrasonic kuzuzisa ukuphola kwe-cathode kanye ne-anode, ijubane lokudlidliza kwe-anodic liyasheshiswa futhi isikhathi sokudlidliza siyafinyezwa;
2. Indlela kasawoti oncibilikisiwe yenza i-graphite enwebekayo.
Hlanganisa izinto eziningana ezifakiwe ne-graphite kanye nokushisa ukuze kwakhiwe i-graphite enwebekayo;
3. Indlela yokusabalalisa igesi isetshenziselwa ukwenza i-graphite enwebekayo.
I-graphite kanye nezinto ezihlanganisiwe zilethwa ngokulandelana emaphethelweni amabili eshubhu elivaliwe nge-vacuum, zishiswe ekugcineni kwezinto ezihlanganisiwe, futhi umehluko wokucindezela kokusabela okudingekayo wakhiwa umehluko wokushisa phakathi kwezinhlangothi ezimbili, ukuze izinto ezihlanganisiwe zingene ungqimba lwe-graphite oluyi-flake esimweni sama-molecule amancane, ngaleyo ndlela kulungiselelwe i-graphite enwebekayo. Inani lezingqimba ze-graphite enwebekayo ekhiqizwa yile ndlela lingalawulwa, kodwa izindleko zayo zokukhiqiza ziphezulu;
4. Indlela yokuhlanganisa amakhemikhali yenza i-graphite enwebekayo.
Izinto zokuqala zokusetshenziswa ezisetshenziselwa ukulungiselela yi-graphite ene-carbon flake ephezulu, kanti ezinye izinto ezisetshenziswayo zamakhemikhali ezifana ne-sulfuric acid egxilile (ngaphezu kuka-98%), i-hydrogen peroxide (ngaphezu kuka-28%), i-potassium permanganate, njll. zonke ziyizinto ezisetshenziswayo zezinga lezimboni. Izinyathelo ezijwayelekile zokulungiselela yilezi ezilandelayo: ekushiseni okufanele, isixazululo se-hydrogen peroxide, i-natural flake graphite kanye ne-sulfuric acid egxilile yezilinganiso ezahlukene kusabela isikhathi esithile ngaphansi kokuxutshwa njalo ngezinqubo ezahlukene zokwengeza, bese kugezwa ngamanzi kuze kube yilapho kungathathi hlangothi, bese kufakwa i-centrifuge. Ngemva kokuphelelwa amanzi emzimbeni, ukomisa nge-vacuum ku-60 °C;
5. Ukukhiqizwa kwe-graphite enwebekayo nge-electrochemical.
Impuphu ye-graphite iphathwa nge-electrolyte enamandla ye-asidi ukuze kwenziwe i-graphite enwebekayo, i-hydrolyzed, igezwe futhi yomiswe. Njengoba i-asidi enamandla, i-sulfuric acid noma i-nitric acid isetshenziswa kakhulu. I-graphite enwebekayo etholakala ngale ndlela inokuqukethwe okuphansi kwe-sulfur.
