Ngemuva kokuthi i-graphite enwebekayo ihanjiswa ngaso leso sikhathi ngokushisa okuphezulu, isikali siba yi-Worm-Like, futhi ivolumu inganwebisa izikhathi eziyi-100-400. Lesi sithombe esandisiwe sigcina izakhiwo ze-graphite yemvelo, sinwebeka kahle, sikhululeke futhi siphikisana, futhi siyamelana nokushisa ngaphansi kwezimo zokuvimbela umoya-mpilo. Uhla olubanzi, lungaba phakathi kuka-200 ~ 3000 ℃, izakhiwo zamakhemikhali zizinzile ngaphansi kokushisa okuphezulu, ukucindezelwa okuphezulu noma ukufakwa kwezimpahla, ezimbonini zezimoto ezishukumisayo kanye nezimoto, umkhumbi kanye nezinto zokufaka izinsiza kunezicelo ezahlukahlukene. Abahleli abalandelayo be-graphite ye-furuit bazokuthatha ukuze baqonde izindlela ezivamile zokukhiqiza zegrafu enwetshiwe:
1. Indlela ye-oxidation ye-ultrasonic ukwenza i-graphite enwetshwayo.
Esezinhlelweni zokulungiselela i-graphite enwebekayo, ukudlidliza kwe-ultrasonic kwenziwa ku-electrolyte anodised, futhi isikhathi sokudlidliza kwe-ultrasonic siyafana nalokho kwe-anodization. Kusukela ukudlidliza kwe-electrolyte ngegagasi le-ultrasonic linenzuzo enkulumweni ye-cathode kanye ne-anode, ijubane le-anodic oxidation liyashesha futhi isikhathi se-oxidation sifinyeziwe;
2. Indlela kasawoti eyenziwe nge-molten yenza i-graphite enwetshwayo.
Hlanganisa ukufakwa okuningana nge-graphite kanye nokushisa ukuze wakhe i-graphite enwebiwe;
I-3. Indlela ye-Gas-Phase-Efforsion isetshenziselwa ukwenza i-graphite enwetshwayo.
I-graphite kanye nezinto ezisetshenziswayo eziphakathi nendawo zilethwa ngamaphethelo amabili weshubhu elivalekile le-vacuum Inani lezendlalelo segrafu elandayo elikhiqizwa ngale ndlela lingalawulwa, kepha izindleko zalo zokukhiqiza ziphakeme;
I-4. Indlela ye-Chemical yokuvala yenza i-graphite enwetshwayo.
Izinto zokuqala ezingavuthiwe ezisetshenziselwa ukulungiswa ziyi-graphite ephezulu ye-carbon flake, kanye nezinye izimpendulo zamakhemikhali ezifana ne-sulfuric acid (ngenhla kwama-98%), i-hydrogen peroxide (ngenhla kwe-28%), njll. Bonke ama-reagents ebangeni lezimboni. Izinyathelo ezijwayelekile zokulungiselela zinjengokulandelayo: ekushiseni okufanele, isixazululo se-hydrogen peroxide, i-sulfuric acid ye-sulfuric ye-sulfuric acijile ukungathathi hlangothi, bese egezwa ngamanzi, ngemuva kokuwohloka komoya, ukomisa ngo-60 ° C;
I-5. Ukukhiqizwa kwe-electrochemical kochungechunge olunwebekayo.
I-graphite powder iphathwa ku-electrolyte eqinile ye-acid ukwenza i-graphite enwetshiwe, i-hydrolyzed, igezwe futhi yomisiwe. Njenge-acid eqinile, i-sulfuric acid noma i-nitric acid isetshenziswa ikakhulukazi. I-graphite enwetshwayo etholakala ngale ndlela inokuqukethwe okuphansi kwesibabule.
