Tšusumetso le melemo ea thepa ea lihlahisoa tsa graphite

Ka lebaka la thepa ea eona e mengata e ikhethang, graphite e sebelisoa haholo makaleng a indasteri a tšepe, mechini, motlakase, lik'hemik'hale, masela le a mang. E sebetsa e le thepa e hanyetsang 'me e boloka litšobotsi tsa pele tsa lik'hemik'hale tsa graphite ea flake ha e ntse e bontša thepa e matla ea ho itlotsa. Phofo ea graphite e khetholloa ka ho hanyetsa asiti e matla haholo, ho hanyetsa mafome, ho mamella mocheso o phahameng ho fihlela ho 3000℃ le ho mamella mocheso o tlase ho fihlela ho -204℃. Ho feta moo, e na le matla a khatello a fetang 800kg/Cm2 mme e bontša ho hanyetsa oxidation ka tahlehelo ea boima ba 1% feela ha e pepesetsoa moeeng ho 450℃. Ho feta moo, e bontša sekhahla sa ho khutla ha 15-50% (botenya ba 1.1-1.5). Ka lebaka leo, lihlahisoa tsa graphite li sebelisoa haholo ho metallurgy, indastering ea lik'hemik'hale, indastering ea petrochemical, fisiks ea matla a phahameng, lifofane, lisebelisoa tsa elektroniki le masimong a mang a fapaneng.

Lihlahisoa tsa graphite ka botsona li na le melemo e meholo haholo:

1, lihlahisoa tsa graphite li na le adsorption e ntle.

Sebopeho se se nang letho sa khabone se etsa hore khabone e be le adsorption e ntle, kahoo khabone hangata e sebelisoa e le thepa ea adsorption bakeng sa ho monya metsi, monko, lintho tse chefo jj. Re entse liteko, matsatsi a 'maloa a fetileng tereing ea ho baka ea barbecue e sebelisitsoeng ka graphite e shebahala e hloekile haholo, empa e behe holim'a ontong ea induction, u tla bona adsorption ea ho qetela ea barbecue ea mafura le lintho tse kotsi e tla tsoa butle-butle, empa u se ke ua tšoenyeha, ka pampiri ea lijo e hloekileng ho hlakola e ka sebelisoa.

2, lihlahisoa tsa graphite li na le conductivity e ntle ea mocheso, phetiso e potlakileng ea mocheso, mocheso o ts'oanang, le poloko ea mafura.

Lipakete le lipane tsa ho baka tse entsoeng ka graphite li futhumatsoa kapele, 'me lijo tse besitsoeng li futhumatsoa ka ho lekana, li phehiloe ho tloha kahare ho ea kantle, 'me nako ea ho futhumatsa e khutšoanyane, eseng feela tatso e hloekileng, empa le limatlafatsi tsa pele tsa lijo li ka notleloa. Re entse liteko, ha pane ea grill ea graphite e sebelisoa bakeng sa ho besa, setofo sa induction se chesa mollo qalong, 'me se ka futhumatsoa ka metsotsoana e 20-30 feela, 'me ha lijo li qalisoa, li ka bapaloa mollong o monyenyane, o ka bolokang matla.

3, lihlahisoa tsa graphite li na le botsitso ba lik'hemik'hale le ho hanyetsa ts'enyeho.

Graphite e na le botsitso bo botle ba lik'hemik'hale mochesong oa kamore 'me ha e hlaseloe ke asiti e matla, motheo o matla le motsoako oa lintho tse phelang. Ka hona, leha tšebeliso ea nako e telele ea lihlahisoa tsa graphite e le tahlehelo e nyane haholo, ha feela e hlakotsoe e le ncha.

Lihlahisoa tse 4 tsa graphite li na le phello e matla ea ho loantša oxidation le phokotso.

Lihlahisoa, haholo-holo ho futhumatsa materase ka graphite li ka hlahisa li-ion tse mpe tsa oksijene, tsa etsa hore lintho tse potolohileng li sebetse, tsa boloka bophelo bo botle ba batho, tsa thibela botsofali ka katleho, tsa etsa hore letlalo le tlale khanya le ho tenyetseha.

5, lihlahisoa tsa graphite bophelo bo botle ba tikoloho, ha ho na tšilafalo ea mahlaseli a kotsi, ho hanyetsa mocheso o phahameng.

Khabone e ka fetoha graphite kamora bonyane matsatsi le masiu a leshome le metso e 'meli a graphitization tikolohong e nang le mocheso o phahameng oa likhato tse 2000-3300, kahoo lintho tse chefo le tse kotsi tse ka har'a graphite li se li lokolotsoe khale 'me li tsitsitse bonyane likhato tse 2000.

Ka nako e ts'oanang, lihlahisoa tsa graphite ka lebaka la sebopeho sa tsona se ikhethang, tse nang le ho hanyetsa mocheso o phahameng, ho hanyetsa ho ts'oaroa ke mocheso, ho tsamaisa motlakase, ho tlotsa, botsitso ba lik'hemik'hale le ho plasticity le litšobotsi tse ling tse ngata, e bile mohloli oa bohlokoa oa maano nts'etsopele ea indasteri ea sesole le ea sejoale-joale 'me theknoloji e phahameng, e ncha le e bohale, lihlahisoa tsa graphite, tse kang mehele ea graphite, likepe tsa graphite li sebelisoa haholo. Litsebi tsa machaba li boletse esale pele hore "lekholo la bo20 la lilemo ke lekholo la silicon, lekholo la bo21 la lilemo e tla ba lekholo la carbon."

Jwalo ka sehlahiswa sa bohlokwa sa diminerale tse seng tsa tshepe, indasteri ya graphite e tla kenngwa tshebetsong taolo ya phihlello. Ka ho kenngwa tshebetsong ha sistimi ya phihlello, graphite, dihlahiswa tsa graphite, di tla fetoha e nngwe kamora rare earth, fluorine chemical, phosphorus chemical, dikhamphani tse etellang pele lefapheng lena di tla kena mohatong o motjha wa ntshetsopele.
