Igraphite eyandiswayo iveliswa ngeenkqubo ezimbini: iikhemikhali kunye ne-electrochemical. Iinkqubo ezimbini zihluke ngaphezu kwenkqubo ye-oxidation, i-deacidification, ukuhlamba amanzi, ukuchithwa kwamanzi, ukomisa kunye nezinye iinkqubo ziyafana. Umgangatho weemveliso zoninzi lwabavelisi abasebenzisa indlela yekhemikhali banokufikelela kwisalathiso esichazwe kumgangatho we-GB10688-89 "eyandiswayo yegraphite", kwaye ihlangabezane neemfuno eziphathekayo zokuveliswa kwephepha legraphite eliguquguqukayo kunye nemigangatho yokubonelela ngaphandle.
Kodwa ukuveliswa kweemfuno ezikhethekileyo ze-volatile ephantsi (≤10%), umxholo wesulfure ephantsi (≤2%) yeemveliso zinzima, inkqubo yokuvelisa ayidluli. Ukomeleza ulawulo lobugcisa, ukufunda inkqubo yonxibelelaniso ngononophelo, ukulawula ubudlelwane phakathi kweeparamitha zenkqubo kunye nokusebenza kwemveliso, kunye nokuvelisa igraphite enomgangatho ozinzileyo wokwandiswa komgangatho zizitshixo zokuphucula umgangatho weemveliso ezilandelayo. Qingdao Furuite Graphite isishwankathelo: indlela electrochemical ngaphandle kwezinye oxidants, iflake yendalo yegraphite kunye anode encedisayo kunye zenza igumbi anode efakwe concentrated sulfuric acid electrolyte, ngokusebenzisa ngqo lwangoku okanye ipulse yangoku, oxidation emva kwexesha elithile ukukhupha, emva kokuhlamba nokomisa. yigraphite eyandisiweyo. Uphawu olukhulu lwale ndlela kukuba iqondo lokuphendula legraphite kunye nesalathisi sokusebenza kwemveliso inokulawulwa ngokulungelelanisa iiparamitha zombane kunye nexesha lokuphendula, ngongcoliseko oluncinci, ixabiso eliphantsi, umgangatho ozinzile kunye nokusebenza okugqwesileyo. Kungxamisekile ukusombulula ingxaki yokuxuba, ukuphucula ukusebenza kakuhle kunye nokunciphisa ukusetyenziswa kwamandla kwinkqubo yokudibanisa.
Emva kwe-deacidification ngeenkqubo ezimbini ezingentla, ubuninzi be-sulfuric acid wetting kunye ne-adsorption ye-graphite interlamellar compounds kusekho malunga ne-1: 1, ukusetyenziswa kwe-agent intercalating kukhulu, kwaye ukusetyenziswa kwamanzi okuhlamba kunye nokukhutshwa kwamanzi amdaka kuphezulu. Kwaye abaninzi abavelisi abazange basombulule ingxaki yokucocwa kwamanzi amdaka, kwimeko yokukhutshwa kwendalo, ukungcoliseka kwendalo kunzulu, kuya kuthintela uphuhliso loshishino.
