Tšebeliso ea lihlahisoa tsa graphite e phahame haholo ho feta kamoo re neng re lebeletse kateng, joale lihlahisoa tsa graphite tseo re li tsebang hona joale ke life?
1,Se sebedisoang joalo ka thepa e tsamaisang
Ha ho qhibiliha litšepe tse fapaneng tsa alloy, ferroalloys, kapa ho hlahisa calcium carbide (calcium carbide) le phosphorus e mosehla ho sebelisa sebōpi sa motlakase sa arc kapa sebōpi sa arc se kentsoeng ka metsing, motlakase o matla o kenngoa sebakeng sa ho qhibiliha ha sebōpi sa motlakase ka li-electrode tsa carbon (kapa ho tsoela pele ho iketsetsa li-electrode paste) kapa li-electrode tsa graphitized ho hlahisa arc, ho fetola matla a motlakase ho matla a mocheso, le ho phahamisa mocheso ho fihla ho likhato tse ka bang 2000 tsa Celsius, ka tsela eo, li finyella litlhoko tsa ho qhibiliha kapa ho itšoara. Metal magnesium, aluminium, le sodium hangata li hlahisoa ke electrolysis e qhibilihisitsoeng ea letsoai. Ka nako ena, lisebelisoa tse tsamaisang anode tsa sele ea electrolytic kaofela ke li-electrode tsa graphite kapa li-electrode tse tsoelang pele tsa ho baka (anode peista, ka linako tse ling anode e bakiloeng pele). Mocheso oa electrolysis ea letsoai e qhibilihisitsoeng hangata o ka tlase ho likhato tse 1000 tsa Celsius. Lisebelisoa tsa anode conductive tse sebelisoang liseleng tsa electrolysis tsa tharollo ea letsoai bakeng sa tlhahiso ea caustic soda (sodium hydroxide) le khase ea chlorine hangata ke li-anode tsa graphitized. Thepa ea conductive bakeng sa hlooho ea sebōpi sa sebōpi sa ho hanyetsa se sebelisoang ha ho etsoa silicon carbide e boetse e sebelisa li-electrode tsa graphitized. Ntle le merero e kaholimo, lihlahisoa tsa carbon le graphite li sebelisoa haholo e le lisebelisoa tse tsamaisang indasteri ea ho etsa likoloi joalo ka mehele e thellang le borashe. Ntle le moo, li boetse li sebelisoa e le lithupa tsa khabone ka libeteri tse omeletseng, li-arc light carbon rods bakeng sa mabone a ho batla kapa arc light generation, le anode ho li-rectifiers tsa mercury.

2,Se sebedisoang joalo ka thepa e refractory
Ka lebaka la bokhoni ba lihlahisoa tsa carbon le graphite ho mamella mocheso o phahameng le ho ba le matla a matla a mocheso o phahameng le ho hanyetsa kutu, masela a mangata a metallurgical a ka hahoa ka li-block blocks, joalo ka tlase, leifo le mpa ea libono tse qhibilihisang tšepe, lesela la libono tsa ferroalloy le libono tsa calcium carbide, le tlase le mahlakoreng a lisele tsa aluminium electrolytic. Li-crucibles tse ngata tse sebelisetsoang ho qhibilihisa litšepe tsa bohlokoa le tse sa tloaelehang, hammoho le li-crucibles tsa graphitized tse sebelisetsoang ho qhibilihisa khalase ea quartz, le tsona li entsoe ka li-billet tse entsoeng ka graphitized. Lihlahisoa tsa carbon le graphite tse sebelisoang e le lisebelisoa tse hanyetsang hangata ha lia lokela ho sebelisoa libakeng tse nang le oxidizing. Hobane carbon kapa graphite e tima ka potlako tlas'a mocheso o phahameng sebakeng se nang le oxidizing.
3,E sebedisoa joalo ka seaho sa sebopeho se hananang le kutu
Li-electrode tse entsoeng ka graphite tse kenngoeng ka li-resin tsa manyolo kapa tsa inorganic li na le litšobotsi tsa ho hanyetsa kutu e ntle, conductivity e ntle ea mocheso, le ho kenella ka tlase. Mofuta ona oa graphite e kentsoeng o boetse o tsejoa e le graphite e ke keng ea qojoa. E sebelisoa haholo ha ho etsoa lihlahisoa tse fapaneng tsa mocheso, litanka tse arabelang, li-condensers, litora tsa mollo, litora tsa ho monya, li-coolers, heaters, filters, lipompo le lisebelisoa tse ling. E sebelisoa haholo makaleng a indasteri a kang ho hloekisa petroleum, petrochemical, hydrometallurgy, acid le alkali production, synthetic fibers, papermaking, 'me e ka boloka lisebelisoa tse ngata tsa tšepe tse kang tšepe e sa hloekang. Tlhahiso ea graphite e sa tsitsang e fetohile lekala la bohlokoa la indasteri ea carbon.

4,E sebelisoa e le thepa e thibelang ho roala le ho tlotsa
Lisebelisoa tsa carbon le graphite ha li na botsitso bo phahameng ba lik'hemik'hale feela, empa hape li na le thepa e ntle ea lubrication. Hangata ho ke ke ha khoneha ho ntlafatsa ho hanyetsa ho apara ha likarolo tse thellang ho sebelisa oli e tlotsang tlas'a maemo a phahameng, mocheso o phahameng le khatello e phahameng. Lisebelisoa tse sa sebetsaneng le graphite li ka sebetsa ntle le ho tlotsa oli ka har'a mecha ea litaba e senyang mocheso o tlohang ho -200 ho isa ho 2000 degrees Celsius le ka lebelo le phahameng la ho thella (ho fihla ho 100 metres / motsotsoana). Ka hona, li-compressor tse ngata le lipompo tse tsamaisang mecha ea litaba e senyang li sebelisa mehele ea piston haholo, mehele e tiisang, le li-bearings tse entsoeng ka thepa ea graphite. Ha li hloke ho eketsoa ha mafura nakong ea ts'ebetso. Thepa ena e manganga e entsoe ka ho kenya lisebelisoa tse tloaelehileng tsa carbon kapa graphite ka resin ea tlhaho kapa lisebelisoa tsa tšepe tse metsi. Emulsion ea graphite e boetse ke setlolo se setle bakeng sa ts'ebetso ea tšepe e ngata (joalo ka ho taka terata le ho taka li-tube).

5,E le thepa e phahameng ea mocheso oa metallurgical le ultrapure
Lisebelisoa tsa meralo tse sebelisoang tlhahisong, joalo ka li-crucibles tsa kholo ea kristale, lijana tsa ho hloekisa libaka, li-brackets, li-fixtures, li-heaters tsa induction, joalo-joalo, kaofela li sebetsoa ka lisebelisoa tse phahameng tsa graphite. Mapolanka le metheo ea graphite e sebelisoang ho qhibilihisa vacuum, hammoho le likarolo tse kang li-tubes tsa sebōpi sa mocheso o phahameng oa mocheso, lithupa, lipoleiti le marang-rang, le tsona li entsoe ka thepa ea graphite. bona haholoanyane ho www.futmetal.com
