I-graphite eyongezwayo iveliswa ziinkqubo ezimbini

I-graphite eyongezwayo iveliswa ziinkqubo ezimbini: iikhemikhali kunye neekhemikhali ze-electrochemical. Ezi nkqubo zimbini zahlukile ukongeza kwinkqubo ye-oxidation, ukukhupha i-asidi, ukuhlamba ngamanzi, ukuphelelwa ngamanzi emzimbeni, ukomisa kunye nezinye iinkqubo ziyafana. Umgangatho weemveliso zabaninzi abavelisi abasebenzisa indlela yeekhemikhali unokufikelela kwisalathiso esichazwe kumgangatho we-GB10688-89 "we-graphite eyongezwayo", kwaye uhlangabezane neemfuno zezinto zokwakha iphepha le-graphite eliguquguqukayo kunye nemigangatho yokubonelela ngokuthunyelwa kwamanye amazwe.

Kodwa ukuveliswa kweemfuno ezikhethekileyo ze-volatible ephantsi (≤10%), umxholo wesalfure ophantsi (≤2%) yeemveliso kunzima, inkqubo yemveliso ayidluli. Ukuqinisa ulawulo lobuchwephesha, ukufunda inkqubo yokudibanisa ngononophelo, ukuqonda ubudlelwane phakathi kweeparamitha zenkqubo kunye nokusebenza kwemveliso, kunye nokuvelisa i-graphite eyongezwayo esemgangathweni ozinzileyo zizitshixo zokuphucula umgangatho weemveliso ezilandelayo. Isishwankathelo se-graphite ye-Qingdao Furuite: indlela ye-electrochemical ngaphandle kwezinye ii-oxidants, i-graphite yendalo ye-flake kunye ne-anode encedisayo kunye zenza igumbi le-anode elifakwe kwi-electrolyte ye-sulfuric acid egxininisiweyo, ngokusebenzisa i-current direct okanye i-pulse current, i-oxidation emva kwexesha elithile lokuyikhupha, emva kokuhlamba nokomisa yi-graphite eyongezwayo. Uphawu olukhulu lwale ndlela kukuba inqanaba lokusabela kwe-graphite kunye ne-index yokusebenza kwemveliso zinokulawulwa ngokulungelelanisa iiparameter zombane kunye nexesha lokuphendula, kunye nongcoliseko oluncinci, iindleko eziphantsi, umgangatho ozinzileyo kunye nokusebenza okugqwesileyo. Kungxamisekile ukusombulula ingxaki yokuxuba, ukuphucula ukusebenza kakuhle kunye nokunciphisa ukusetyenziswa kwamandla kwinkqubo yokudibanisa.

Emva kokunciphisa i-asidi ngezi nkqubo zimbini zingasentla, umlinganiselo wobunzima be-sulfuric acid wetting kunye ne-adsorption ye-graphite interlamellar compounds usemalunga ne-1:1, ukusetyenziswa kwe-intercalating agent kukhulu, kwaye ukusetyenziswa kwamanzi okuhlamba kunye nokukhutshwa kwamanzi amdaka kuphezulu. Kwaye uninzi lwabavelisi aluzange lusisombulule ingxaki yokunyangwa kwamanzi amdaka, kwimeko yokukhutshwa kwendalo, ungcoliseko lokusingqongileyo lubi kakhulu, luya kuyithintela uphuhliso lweshishini.
