Graphite e atolositsoeng e hlahisoa ke lits'ebetso tse peli

Graphite e atolositsoeng e hlahisoa ke lits'ebetso tse peli: lik'hemik'hale le motlakase. Lits'ebetso tsena tse peli li fapane ntle le ts'ebetso ea oxidation, deacidification, ho hlatsoa metsi, ho omella, ho omisa le lits'ebetso tse ling lia tšoana. Boleng ba lihlahisoa tsa bahlahisi ba bangata ba sebelisang mokhoa oa lik'hemik'hale bo ka fihla ho index e boletsoeng ho GB10688-89 "expandable graphite" standard, le ho fihlela litlhoko tsa thepa bakeng sa tlhahiso ea lipampiri tsa graphite tse ngata le maemo a phepelo ea kantle ho naha.

Empa tlhahiso ea litlhoko tse ikhethang tsa maemo a tlase a sa tsitsang (≤10%), litaba tse tlase tsa sebabole (≤2%) tsa lihlahisoa li thata, ts'ebetso ea tlhahiso ha e fete. Ho matlafatsa botsamaisi ba tekheniki, ho ithuta ts'ebetso ea ho kenyelletsa litšepe ka hloko, ho tseba kamano lipakeng tsa mekhahlelo ea ts'ebetso le ts'ebetso ea sehlahisoa, le ho hlahisa boleng bo tsitsitseng ba graphite e atolohang ke linotlolo tsa ho ntlafatsa boleng ba lihlahisoa tse latelang. Qingdao Furuite graphite kakaretso: mokhoa oa elektrochemical ntle le li-oxidants tse ling, tlhaho ea flake graphite le anode e thusang hammoho li theha kamore ea anode e inetsoeng ka sulfuric acid electrolyte, ka ho otlolla hona joale kapa hona joale, oxidation kamora nako e itseng ho e ntša, kamora ho hlatsoa le ho omisa graphite e pharalletseng. Sebopeho se seholo sa mokhoa ona ke hore graphite ea tšebetso le index ea ts'ebetso ea sehlahisoa li ka laoloa ka ho fetola mekhahlelo ea motlakase le nako ea karabelo, ka ts'ilafalo e nyane, theko e tlase, boleng bo tsitsitseng le ts'ebetso e ntle. Ho potlakile ho rarolla bothata ba ho tsoaka, ho ntlafatsa tšebetso le ho fokotsa ts'ebeliso ea motlakase ts'ebetsong ea ho kenella.

Kamora ho tlosa deacidification ka lits'ebetso tse peli tse kaholimo, karolelano ea boima ba ho monya acid ea sulfuric le adsorption ea metsoako ea graphite interlamellar e ntse e le ka 1: 1, ts'ebeliso ea moemeli oa li-intercalating e kholo, mme ts'ebeliso ea metsi a hlatsoang le phallo ea likhoerekhoere li phahame. Mme baetsi ba bangata ha ba rarolle bothata ba kalafo ea metsi a litšila, maemong a tlhaho ea tlhaho, ts'ilafalo ea tikoloho e tebile, e tla thibela nts'etsopele ea indasteri.
