I-graphite enwebekayo ikhiqizwa izinqubo ezimbili

I-graphite enwebekayo ikhiqizwa izinqubo ezimbili: amakhemikhali kanye ne-electrochemical. Lezi zinqubo ezimbili zihlukile ngaphezu kwenqubo ye-oxidation, i-deacidification, ukugeza amanzi, ukuphelelwa amandla kwamanzi, ukomisa nezinye izinqubo ziyafana. Izinga lemikhiqizo yeningi labakhiqizi abasebenzisa indlela yamakhemikhali lingafinyelela inkomba eshiwo kuzinga le-GB10688-89 “legraphite enwebekayo”, futhi lihlangabezane nezimfuneko zezinto ezibonakalayo zokukhiqizwa kweshidi legraphite eliguquguqukayo ngobuningi kanye namazinga okunikezela okuthunyelwa ngaphandle.

Kodwa ukukhiqizwa kwezidingo ezikhethekile zokuguquguquka okuphansi (≤10%), okuqukethwe kwesibabule esincane (≤2%) kwemikhiqizo kunzima, inqubo yokukhiqiza ayidluli. Ukuqinisa ukuphathwa kobuchwepheshe, ukufunda inqubo yokuhlanganisa ngokucophelela, ukuqonda ubudlelwano phakathi kwemingcele yenqubo nokusebenza komkhiqizo, kanye nokukhiqiza ikhwalithi ezinzile yegraphite enwebekayo kuwukhiye wokuthuthukisa ikhwalithi yemikhiqizo elandelayo. I-Qingdao Furuite Graphite isifinyezo: indlela ye-electrochemical ngaphandle kwamanye ama-oxidants, i-flake yemvelo ye-graphite kanye ne-anode eyisizayo ndawonye yakha igumbi le-anode elifakwe ku-electrolyte ye-sulfuric acid egxilile, ngokusebenzisa okwamanje okuqondile noma i-pulse current, i-oxidation ngemva kwesikhathi esithile ukuyikhipha, ngemva kokugeza nokomisa. i-graphite enwebekayo. Isici esikhulu kunazo zonke sale ndlela ukuthi izinga lokuphendula le-graphite kanye nenkomba yokusebenza yomkhiqizo ingalawulwa ngokulungisa imingcele kagesi kanye nesikhathi sokuphendula, ngokungcola okuncane, izindleko eziphansi, ikhwalithi ezinzile kanye nokusebenza okuhle kakhulu. Kuyaphuthuma ukuxazulula inkinga yokuxuba, ukuthuthukisa ukusebenza kahle nokunciphisa ukusetshenziswa kwamandla enqubweni yokuhlanganisa.

Ngemuva kokususwa kwe-acidification ngezinqubo ezimbili ezingenhla, isilinganiso esikhulu sokumanzisa i-sulfuric acid kanye ne-adsorption ye-graphite interlamellar compounds namanje mayelana ne-1: 1, ukusetshenziswa kwe-ejenti ye-intercalating kukhulu, futhi ukusetshenziswa kwamanzi okugeza kanye nokukhishwa kwendle kuphezulu. Futhi abakhiqizi abaningi abazange baxazulule inkinga yokwelashwa kwamanzi angcolile, esimweni sokukhishwa kwemvelo, ukungcoliswa kwemvelo kubi kakhulu, kuzovimbela ukuthuthukiswa komkhakha.
