Litheknoloji tsa Tlhahiso:

Graphiteke ntho e ikhethang eo e seng ea tšepe e entsoeng ka liathomo tsa k'habone tse hlophisitsoeng ka sebopeho sa sekoti sa hexagonal. Ke thepa e bonolo le e brittle e sebelisoang hangata lits'ebetsong tse fapaneng tsa indasteri ka lebaka la thepa ea eona e ikhethang. Graphite e ka boloka matla le botsitso ba eona esita le mochesong o fetang 3600 ° C. Joale e-re ke tsebise mokhoa oa ho hlahisa graphite e khethehileng.

Isostatic graphite, e entsoeng ka bohloeki bo phahameng ba graphite ka ho hatisa, ke thepa e ke keng ea fetoha e sebelisoang ha ho etsoa libono tsa kristale tse le 'ngoe, li-crystallizers tsa tšepe tse tsoelang pele, le li-electrode tsa graphite bakeng sa machining a motlakase a spark discharge. Ntle le lits'ebetso tsena tsa mantlha, e sebelisoa haholo masimong a li-alloys tse thata (li-heaters tsa vacuum sebōpi, lipoleiti tsa sintering, joalo-joalo), merafo (ho etsa liforomo tsa drill bit), indasteri ea lik'hemik'hale (li-exchangers tsa mocheso, likarolo tse thibelang ho bola), metallurgy (crucibles), le mechini (litiiso tsa mochini).

Molao-motheo oa theknoloji ea khatello ea isostatic o thehiloe molaong oa Pascal. E fetola khatello ea unidirectional (kapa bidirectional) ea thepa hore e be compression ea litsela tse ngata (omnidirectional). Nakong ea ts'ebetso, likaroloana tsa carbon li lula li le boemong bo sa tsitsang, 'me boima ba molumo bo batla bo tšoana le thepa ea isotropic. Ntle ho moo, ha e tlas'a bophahamo ba sehlahisoa, kahoo ho etsa hore graphite ea isostatic e se ke ea e-ba le liphapang tse fokolang kapa tse fokolang tsa tshebetso.
Ho ea ka mocheso oo ho etsoa le ho tiisa ho etsoang teng, theknoloji ea ho hatella ea isostatic e ka aroloa ka ho tobetsa ha isostatic ho batang, ho hatella ha isostatic ka mofuthu, le ho hatella ho chesang ha isostatic. Lihlahisoa tse hatellang tsa Isostatic li na le sesupo se phahameng, hangata ho 5% ho isa ho 15% ho feta tsa lihlahisoa tse hatellang tsa hlobo kapa tse peli. Boima ba lihlahisoa tsa khatello ea isostatic bo ka fihla ho 99.8% ho isa ho 99.09%.

Graphite e bōpiloeng e na le litšoantšiso tse ikhethang ka matla a mochine, ho hanyetsa abrasion, density, hardness le conductivity ea motlakase 'me litšoantšiso tsena li ka ntlafatsoa le ho feta ka ho kenya resin kapa tšepe.

Mokhoa oa ho bopa hangata o sebelisoa ho hlahisa graphite e hatelitsoeng ka serame e nyane kapa lihlahisoa tse hlophisitsoeng hantle. Molao-motheo ke ho tlatsa palo e itseng ea peista ka har'a hlobo ea sebopeho le boholo bo hlokahalang, ebe o sebelisa khatello e tsoang holimo kapa tlase. Ka linako tse ling, sebelisa khatello ho tloha mahlakoreng ka bobeli ho hatella pente hore e be sebōpeho ka har'a hlobo.

Ho na le mechini ea ho bopa e otlolohileng le e otlolohileng. Mokhoa oa ho bopa ka kakaretso o ka hatella sehlahisoa se le seng ka nako, kahoo se na le katleho e tlase ea tlhahiso. Leha ho le joalo, e ka hlahisa lihlahisoa tse nepahetseng haholo tse ke keng tsa etsoa ke mahlale a mang. Ho feta moo, katleho ea tlhahiso e ka ntlafatsoa ka ho hatella ka nako e le 'ngoe ea mefuta e mengata le mela ea tlhahiso e ikemetseng.

graphite e ekelitsoeng e thehoa ka ho kopanya likaroloana tse phahameng tsa graphite tse hloekileng le binder ebe e li ntša ka extruder. Ha ho bapisoa le isostatic graphite, graphite e extruded e na le boholo ba lijo-thollo tse mahoashe le matla a tlaase, empa e na le mocheso o phahameng oa mocheso le motlakase.
Hona joale, lihlahisoa tse ngata tsa carbon le graphite li hlahisoa ka mokhoa oa extrusion. Li sebelisoa haholo-holo e le lisebelisoa tsa ho futhumatsa le lisebelisoa tsa ho futhumatsa mocheso lits'ebetsong tsa phekolo ea mocheso o phahameng oa mocheso. Ntle le moo, li-graphite blocks li ka sebelisoa hape e le li-electrode ho etsa phetiso ea hajoale lits'ebetsong tsa electrolysis. Ka hona, li sebelisoa haholo e le litiiso tsa mochini, lisebelisoa tse tsamaisang mocheso le lisebelisoa tsa elektrode libakeng tse feteletseng joalo ka mocheso o phahameng, khatello e phahameng le lebelo le phahameng.

Mokhoa oa extrusion ke ho kenya pente ka har'a cylinder ea peista ea mochine oa khatiso le ho e ntša. Mochine oa khatiso o na le selikalikoe sa extrusion se ka nkeloang sebaka (se ka nkeloa sebaka ho fetola sebopeho le boholo ba sehlahisoa) ka pel'a sona, 'me ho fanoa ka sekontiri se tsamaeang ka pel'a lesale la extrusion. The plunger e ka sehloohong ea mochine oa khatiso e fumaneha ka mor'a cylinder ea peista.
Pele o kenya khatello, beha moferefere ka pel'a selikalikoe sa extrusion, 'me u sebelise khatello ho tloha lehlakoreng le fapaneng ho hatella pente. Ha baffle e tlosoa 'me khatello e ntse e tsoela pele ho sebelisoa, pente e ntšoa ho tloha lesale la extrusion. Khaola sekhahla se fetisitsoeng ka bolelele bo lakatsehang, se pholile 'me u se hlahlobe pele u se beha. Mokhoa oa extrusion ke mokhoa o tsoelang pele oa tlhahiso, e leng se bolelang hore ka mor'a hore ho eketsoe palo e itseng ea pente, lihlahisoa tse 'maloa (li-graphite, lisebelisoa tsa graphite) li ka tsoela pele ho fetisoa.
Hona joale, lihlahisoa tse ngata tsa carbon le graphite li hlahisoa ka mokhoa oa extrusion.
