Graphite ke ntho e ikhethang le e ikhethang e nang le thepa e tsotehang ea mocheso oa motlakase. Thermal conductivity ea graphite e eketseha ka ho eketseha ha mocheso, 'me conductivity ea eona ea mocheso e ka fihla ho 1500-2000 W / (mK) mocheso oa kamore, e ka bang makhetlo a 5 ao ea koporo le makhetlo a fetang 10 a aluminium ea tšepe.
Thermal conductivity e bolela bokhoni ba thepa ho tsamaisa mocheso.E lekanngoa ho latela hore na mocheso o ka tsamaea kapele hakae nthong.Graphite, mofuta oa tlhaho oa carbon, o na le e 'ngoe ea mekhoa e phahameng ka ho fetisisa ea mocheso har'a lisebelisoa tsohle tse tsejoang.E bonts'a conductivity e ikhethang ea mocheso ka lehlakoreng la perpendicular ho likarolo tsa eona, e e etsa sesebelisoa se loketseng lits'ebetso tse ngata.
Sebopeho sa graphitee na le lihlopha tsa liathomo tsa k'habone tse hlophisitsoeng ka lesela la hexagonal.Ka har'a sekhahla se seng le se seng, liathomo tsa carbon li kopantsoe hammoho ke li-covalent bond tse matla.Leha ho le joalo, maqhama pakeng tsa lihlopha, tse tsejoang e le mabotho a Van der Waals, a batla a fokola.Ke tlhophiso ea liathomo tsa carbon ka har'a mekhahlelo ena e fanang ka graphite litšobotsi tsa eona tse ikhethang tsa ho tsamaisa mocheso.
Thermal conductivity ea graphite e haholo-holo ka lebaka la khabone e phahameng ea eona le sebopeho se ikhethang sa kristale.Litlamo tsa carbon-carbon ka har'a lesela le leng le le leng li lumella mocheso hore o fetele habonolo sefofaneng sa lera.Ho tloha ho Ho tloha ho motsoako oa lik'hemik'hale oa graphite, re ka utloisisa matla a fokolang a marang-rang a etsang hore ho khonehe hore li-phonon (vibrational energy) li tsamaee ka potlako. ka lethati.
Tšebeliso e phahameng ea mocheso oa graphite e entse hore e sebelisoe haholo liindastering tse sa tšoaneng.
I: Ho hlahisa electrode ea graphite.
Graphite ke e 'ngoe ea lisebelisoa tse ka sehloohong bakeng saho etsa electrode ea graphite, e nang le melemo ea mocheso o phahameng oa mocheso, ho hanyetsa mocheso o phahameng, botsitso bo botle ba lik'hemik'hale, matla a phahameng a mochine, kahoo e sebelisoa haholo ka metallurgy, indasteri ea lik'hemik'hale, matla a motlakase le liindasteri tse ling ts'ebetsong ea sebōpi sa electrolytic le motlakase.
II: Graphite e sebelisoa tšimong ea elektronike.
Graphite e sebelisoa e le lisebelisoa tsa ho futhumatsa mocheso ho qhala mocheso o hlahisoang ke lisebelisoa tsa elektronike tse kang li-transistors, li-circuits tse kopantsoeng le li-module tsa matla.Bokhoni ba eona ba ho fetisetsa mocheso ka katleho hole le lisebelisoa tsena ho thusa ho boloka botsitso le ho thibela ho chesa haholo.
III:graphite e sebelisoa ha ho etsoalithupale hlobo bakeng sa ho etsa tšepe.
Ts'ebetso ea eona e phahameng ea mocheso e lumella ho fetisoa ha mocheso hantle, ho etsa bonnete ba ho futhumala ho tšoanang le ho pholile ha tšepe.Sena, le sona, se ntlafatsa boleng le botsitso ba sehlahisoa sa ho qetela.
IV: Graphite thermal conductivity e sebelisoa indastering ea lifofane.
Likarolo tsa graphite li sebelisoa kahong ea likarolo tsa lifofane le tsa sepaka-paka.Mehaho e ikhethang ea ho fetisa mocheso ea graphite e thusa ho laola mocheso o feteletseng o bang teng nakong ea maeto a sebaka le maeto a lifofane a lebelo le phahameng.
V: Graphite e sebelisoa e le setlolo liindastering tse fapaneng.
Hangata e sebelisoa lits'ebetsong tsa tlhahiso moo mocheso o phahameng le likhatello li amehang, joalo ka lienjineri tsa likoloi le mechini ea tšepe.Bokhoni ba graphite ba ho mamella mocheso o phahameng ha o ntse o fokotsa khohlano e etsa hore e be setlolo se loketseng lits'ebetso tse joalo.
VI: Graphite e sebelisoa lipatlisisong tsa mahlale.
Hangata e sebelisoa e le thepa e tloaelehileng ea ho lekanya mocheso oa mocheso oa lintho tse ling.Litekanyetso tse thehiloeng hantle tsa mocheso oa mocheso oa graphite li sebetsa e le sebaka sa ho bapisa le ho hlahloba thepa ea ho fetisa mocheso ea thepa e fapaneng.
Qetellong, graphite thermal conductivity e ikhetha ka lebaka la sebopeho sa eona se ikhethang sa kristale le lik'habone tse phahameng.Bokhoni ba eona ba ho fetisa mocheso ka nepo bo entse hore e be ea bohlokoa haholo liindastering tse fapaneng, ho kenyeletsoa lisebelisoa tsa elektroniki, lisebelisoa tsa tšepe, sebaka sa sefofane, le lubrication.Ho feta moo, graphite e sebetsa e le sesebelisoa sa benchmark bakeng sa ho lekanya ho tsamaisa mocheso oa lintho tse ling.Ka ho utloisisa le ho sebelisa tse ikhethanglitšobotsi tsa graphite, re ka tsoela pele ho hlahloba likopo tse ncha le tsoelo-pele tšimong ea ho fetisa mocheso le tsamaiso ea mocheso.
