Isostatic petelitsoe graphiteke mofuta o mocha oa thepa ea graphite, e nang le motlakase o babatsehang oa motlakase, ho hanyetsa mocheso o phahameng le botsitso ba lik'hemik'hale, kahoo e sebelisoa haholo libakeng tse ngata tsa theknoloji e phahameng. Pampiri ena e tla hlahisa ka ho qaqileng ts'ebetso ea tlhahiso, ts'ebeliso ea mantlha le mokhoa oa ntlafatso oa nakong e tlang oagraphite e hatelitsoeng ke isostatic.
Mokhoa oa tlhahiso eagraphite e hatelitsoeng ke isostatic
Ts'ebetso ea tlhahiso ea graphite ea isostatic haholo-holo e kenyelletsa mehato e latelang:
1. Tokiso ea thepa e tala: Lisebelisoa tse tala tsa graphite e hatelitsoeng ke isostatic li kenyelletsa kakaretso le binder. Hangata kakaretso e entsoe ka petroleum coke kapa asphalt coke, e hlokang ho calcined ho 1200 ~ 1400 ℃ ho tlosa mongobo le li-volatile pele li ka sebelisoa. Setlamo se entsoe ka sekontiri sa mashala kapa sekontiri sa petroleum, se atolohang le ho etsa likonteraka ka mokhoa o lumellanang le kakaretso ho netefatsa isotropy ea thepa.
2. Ho sila: Thepa e tala e siloa hore e be phofo e ntle, eo hangata e hlokang hore boholo ba kakaretso bo fihle ho 20um kapa ka tlaase ho moo. E ntle ka ho fetisisagraphite e hatisitsoeng ka isostatically, e nang le bophara bo boholo ba karoloana ea 1μm, e ntle haholo.
3. Cold isostatic pressing: Beha phofo ea fatše ka har'a mochine o batang oa isostatic mme o o hatelle ho theha tlas'a khatello e phahameng.
4. Ho halika: graphite e bōpiloeng e kenngoa ka sebōping sa ho baka ebe e besoa ka mocheso o phahameng ho ntlafatsa ho feta tekanyo ea graphitization.
5. Potoloho ea ho halika ha "Ipregnation-roasting cycle": E le hore ho finyelloe sepheo sa sepheo, ho hlokahala hore ho be le li-cycle tse ngata tsa ho belisa. Potoloho e 'ngoe le e' ngoe e eketsa bongata ba graphite, ho fihlela matla a phahameng le ho tsamaisa motlakase.
Lisebelisoa tse ka sehloohong tsagraphite ea isostatickenyeletsa tse latelang:
1. Sebaka sa elektroniki:graphite e hatisitsoeng ka Isostaticallye sebelisoa haholo lefapheng la lisebelisoa tsa elektroniki ka lebaka la ts'ebetso ea eona e ntle ea motlakase. Haholo-holo masimong a libeteri, li-electrode, lisebelisoa tsa semiconductor, joalo-joalo, motlakase oa eona o motle o etsa hore graphite e hatelletsoeng ke isostatic e be ntho ea bohlokoa haholo.
2. Sebaka sa Aerospace: graphite e hatelitsoeng ke isostatic e na le litšobotsi tsa ho hanyetsa mocheso o phahameng, botsitso ba lik'hemik'hale le matla a phahameng, kahoo e sebelisoa haholo tšimong ea sefofane. Ka mohlala, ka lienjineng tsa rokete le li-probe tsa sebaka.graphite e hatisitsoeng ka isostaticallye sebelisetsoa ho etsa likarolo tse tsamaisang motlakase tlas'a mocheso o phahameng, maemo a phahameng a khatello.
3. Sebaka sa likoloi:graphite e hatelitsoeng ke isostatice boetse e sebelisoa haholo tšimong ea likoloi. Ka mohlala, tšimong ea libeteri, graphite e hatelitsoeng ka isostatically e sebelisoa ho etsa li-electrode tsa betri tse sebetsang hantle. Ho feta moo, likarolong tsa enjene ea likoloi, graphite e hatelitsoeng ea isostatic e boetse e sebelisetsoa ho etsa litiiso le ho roala likarolo tlas'a mocheso o phahameng le maemo a khatello e phahameng.
4. Libaka tse ling: Ho phaella masimong a ka holimo, graphite ea isostatic e boetse e sebelisoa haholo ho matla, indasteri ea lik'hemik'hale, metallurgy le masimo a mang. Ka mohlala, tšimong ea lisele tsa letsatsi,graphite e hatisitsoeng ka isostaticallye sebelisetsoa ho etsa li-electrode tse sebetsang hantle haholo le li-conductive substrates. Ka indasteri ea lik'hemik'hale,graphite e hatisitsoeng ka isostaticallye sebelisetsoa ho etsa liphaephe le lijana tse nang le khanyetso e phahameng ea kutu. Ka metallurgy,graphite e hatisitsoeng ka isostaticallye sebelisoa ho etsa litofo le li-electrode tsa mocheso o phahameng.
Joaloka mofuta o mocha oa thepa ea graphite, graphite e hatelitsoeng ea isostatic e na le mefuta e mengata ea tšebeliso le boleng ba bohlokoa. Ts'ebetso ea eona ea tlhahiso e rarahane ebile ha e bonolo, 'me e hloka ho feta mehatong e mengata hore e phethe. Leha ho le joalo, ke mehato ena e rarahaneng ea ts'ebetso e etsang hore graphite e hatelitsoeng ka isostatically e be le thepa e ntle haholo le tebello e pharaletseng ea ts'ebeliso. Nakong e tlang, ka tsoelo-pele e tsoelang pele ea saense le thekenoloji le katoloso ea masimo a kopo, graphite e hatelitsoeng ea isostatic e tla sebelisoa haholo le ho khothaletsoa. Ka nako e ts'oanang, lipatlisiso le ntlafatso ea ts'ebetso ea tlhahiso le theknoloji le tsona e tla ba sepheo sa lipatlisiso. Ho lumeloa hore haufinyane graphite ea isostatic e tla re tlisetsa lintho tse makatsang le menyetla e mengata.
