Kugwiritsa ntchito zinthu za graphite ndikokwera kwambiri kuposa momwe timayembekezera, ndiye ndi ntchito ziti za graphite zomwe tikudziwa pano?
1,Amagwiritsidwa ntchito ngati conductive material
Mukasungunula zitsulo zosiyanasiyana za aloyi, ferroalloys, kapena kupanga calcium carbide (calcium carbide) ndi phosphorous yachikasu pogwiritsa ntchito ng'anjo yamagetsi yamagetsi kapena ng'anjo yamadzi, mphamvu yamagetsi imalowetsedwa m'malo osungunuka a ng'anjo yamagetsi kudzera mu ma electrode a carbon (kapena kudziwotcha mosalekeza. ma elekitirodi - mwachitsanzo ma elekitirodi phala) kapena maelekitirodi opangidwa ndi graphitized kuti apange arc, kutembenuza mphamvu yamagetsi kukhala mphamvu ya kutentha, ndikukweza kutentha mpaka pafupifupi madigiri 2000 Celsius, potero kukwaniritsa zofunikira za smelting kapena kuchitapo kanthu. Metal magnesium, aluminium, ndi sodium nthawi zambiri amapangidwa ndi electrolysis yosungunuka yamchere. Panthawiyi, zinthu zopangira anode za cell electrolytic ndi ma electrode a graphite kapena maelekitirodi odziwotcha osalekeza (anode phala, nthawi zina anode yophika kale). Kutentha kwa electrolysis ya mchere wosungunuka nthawi zambiri kumakhala pansi pa 1000 digiri Celsius. Zida zopangira anode zomwe zimagwiritsidwa ntchito m'maselo amchere a electrolysis popanga caustic soda (sodium hydroxide) ndi mpweya wa chlorine nthawi zambiri amakhala ma graphitized anode. Zinthu zopangira ng'anjo ya ng'anjo yomwe imagwiritsidwa ntchito popanga silicon carbide imagwiritsanso ntchito ma electrode a graphitized. Kuphatikiza pazifukwa zomwe tafotokozazi, zinthu za kaboni ndi ma graphite zimagwiritsidwa ntchito kwambiri ngati zida zopangira ma mota ngati mphete ndi maburashi. Kuphatikiza apo, amagwiritsidwanso ntchito ngati ndodo za kaboni m'mabatire owuma, ndodo za arc light carbon for searchlights kapena arc light generation, ndi anodes mu mercury rectifiers.

2,Ntchito ngati refractory zinthu
Chifukwa cha kuthekera kwa zinthu za carbon ndi graphite kuti zipirire kutentha kwambiri komanso kukhala ndi mphamvu zotentha kwambiri komanso kukana dzimbiri, ng'anjo zambiri zazitsulo zimatha kumangidwa ndi zitsulo za carbon, monga pansi, m'mimba, ndi mimba ya ng'anjo zosungunulira zachitsulo, ng'anjo za ferroalloy ndi ng'anjo za calcium carbide, ndi pansi ndi mbali za ma cell a aluminiyamu electrolytic. Ma crucibles ambiri omwe amagwiritsidwa ntchito posungunula zitsulo zamtengo wapatali komanso zosowa, komanso ma graphitized crucibles omwe amagwiritsidwa ntchito posungunula magalasi a quartz, amapangidwanso kuchokera ku mapepala a graphitized. Zinthu za carbon ndi graphite zomwe zimagwiritsidwa ntchito ngati zowumitsa siziyenera kugwiritsidwa ntchito mumlengalenga wotulutsa okosijeni. Chifukwa carbon kapena graphite imatentha mofulumira kutentha kwambiri m'mlengalenga wotsekemera.
3,Ntchito ngati dzimbiri zosagwira structural chuma
Maelekitirodi opangidwa ndi graphitized omwe amapangidwa ndi utomoni wachilengedwe kapena wachilengedwe amakhala ndi mawonekedwe abwino okana dzimbiri, matenthedwe abwino, komanso kutsika kochepa. Mtundu uwu wa graphite wolowetsedwa umadziwikanso kuti impermeable graphite. Amagwiritsidwa ntchito kwambiri popanga zosinthira kutentha zosiyanasiyana, akasinja ochitira, ma condensers, nsanja zoyaka moto, nsanja zoyatsira, zoziziritsa kukhosi, zotenthetsera, zosefera, mapampu, ndi zida zina. Amagwiritsidwa ntchito kwambiri m'mafakitale monga kuyenga mafuta, petrochemical, hydrometallurgy, asidi ndi alkali kupanga, ulusi wopangira, kupanga mapepala, ndipo amatha kupulumutsa zitsulo zambiri monga chitsulo chosapanga dzimbiri. Kupanga kwa graphite yosasunthika kwakhala gawo lofunikira kwambiri pamakampani opanga mpweya.

4,Amagwiritsidwa ntchito ngati zinthu zosavala komanso zopaka mafuta
Zida za carbon ndi graphite sizingokhala ndi kukhazikika kwa mankhwala, komanso zimakhala ndi mafuta abwino. Nthawi zambiri zimakhala zosatheka kuwongolera kukana kwa zida zotsetsereka pogwiritsa ntchito mafuta opaka mafuta mothamanga kwambiri, kutentha kwambiri, komanso kupanikizika kwambiri. Graphite kuvala zosagwira zipangizo akhoza ntchito popanda mafuta mafuta TV zikuwononga pa kutentha kuyambira -200 mpaka 2000 madigiri Celsius ndi pa liwiro kutsetsereka (mpaka 100 mamita/sekondi). Chifukwa chake, ma compressor ambiri ndi mapampu omwe amanyamula zinthu zowononga kwambiri amagwiritsa ntchito mphete za pistoni, mphete zomata, ndi mayendedwe opangidwa ndi zida za graphite. Iwo safuna Kuwonjezera mafuta pa ntchito. Zinthu zosamva izi zimapangidwa ndikuyika zida wamba za kaboni kapena graphite ndi organic resin kapena zitsulo zamadzimadzi. Graphite emulsion ndi mafuta abwino opangira zitsulo zambiri (monga kujambula waya ndi kujambula chubu).

5,Monga mkulu-kutentha metallurgical ndi ultrapure zakuthupi
Zida zomangira zomwe zimagwiritsidwa ntchito popanga, monga ma crystal kukula crucibles, zotengera zoyenga zachigawo, mabatani, zosintha, zotenthetsera zotenthetsera, ndi zina zotero, zonse zimakonzedwa kuchokera ku zida za graphite zoyera kwambiri. Ma board otsekemera a graphite ndi maziko omwe amagwiritsidwa ntchito posungunula vacuum, komanso zinthu monga machubu a ng'anjo yotentha kwambiri, ndodo, mbale, ndi ma gridi, amapangidwanso ndi zida za graphite. onani zambiri pa www.futmetal.com
