Ma electrode a graphite amphamvu kwambiri agwiritsidwa ntchito kwambiri m'mbali zotsatirazi:
1. Zipangidwe za grafiti zoperekera zitsulo zosapanga dzimbiri komanso zosapanga dzimbiri
M'zaka zaposachedwapa, njira zopangira zapamwamba monga kupanga mipiringidzo mwachindunji (kapena theka-continuous) ya mipiringidzo kapena machubu kuchokera ku chitsulo chosungunuka zakhala zikulimbikitsidwa kunyumba ndi kunja. Njirayi yayamba kugwiritsidwa ntchito ku China m'mbali monga mkuwa, zitsulo zamkuwa, aluminiyamu ndi zitsulo zotayidwa. Graphite yopangidwa imaonedwa ngati chinthu choyenera kwambiri popanga zitsulo zopanda chitsulo kapena zitsulo zotayidwa. Kuchita bwino popanga zinthu kwatsimikizira kuti chifukwa chogwiritsa ntchito zitsulo zotayidwa, zomwe zimakhala ndi kutentha kwabwino (kutentha kwa kutentha kumatsimikiza liwiro lolimba la zitsulo kapena zitsulo zotayidwa) komanso magwiridwe antchito abwino odzipaka mafuta, sikuti liwiro loponya limawonjezeka kokha, komanso chifukwa kukula kwa inget ndi kolondola, pamwamba pake ndi posalala, ndipo kapangidwe ka kristalo ndi kofanana, njira yotsatira yopangira zinthu ikhoza kuchitidwa mwachindunji. Izi sizimangowonjezera kwambiri zokolola za zinthu zomalizidwa ndikuchepetsa kutayika kwa zinyalala, komanso zimakweza kwambiri mtundu wa zinthuzo.
Pali mitundu iwiri ya njira zoperekera zinthu mosalekeza: kuponya zinthu mosalekeza molunjika ndi kuponya zinthu mosalekeza mopingasa.
2. Zoumba zoponyera mokakamiza
Zipangizo zopangira graphite zagwiritsidwa ntchito bwino popangira zitsulo zopanda chitsulo. Mwachitsanzo, zitsulo zopangidwa ndi zinc alloy ndi copper alloy zopangidwa ndi pressure casting molds zopangidwa ndi graphite zopangidwa zakhala zikugwiritsidwa ntchito m'magalimoto ndi zina.
3. Diya yotenthetsera yotentha
Ma graphite opangidwa ndi kutentha kwambiri amakhala ndi makhalidwe otsatirawa akagwiritsidwa ntchito popopera mphamvu ya carbide yopangidwa ndi simenti:
Choyamba, ngati kutentha kokakamiza kwakwezedwa kufika madigiri 1350-1450, kuthamanga kwa unit komwe kumafunika kungachepe kufika pa mphamvu ya makilogalamu 67-100 pa sentimita imodzi (ndiko kuti, gawo limodzi mwa magawo khumi a kuthamanga kozizira kokakamiza). Chachiwiri, kupanikizika ndi kutentha kumachitika mwanjira yomweyo, ndipo thupi lokhuthala louma lingapezeke patatha nthawi yochepa yowotcha.
4. Zipatso zopangira magalasi
Chifukwa cha kukhazikika kwa mankhwala a zinthu za graphite, kukana kwawo kunyowa ndi galasi losungunuka, komanso kuti sasintha kapangidwe ka galasi, komanso kukana kwawo kutentha komanso kusintha pang'ono kwa kutentha, akhala zinthu zofunika kwambiri popanga magalasi m'zaka zaposachedwa. Angagwiritsidwe ntchito popanga zinyalala za machubu agalasi, machubu a chigongono, ma funnel, ndi mabotolo ena osiyanasiyana agalasi ooneka ngati apadera.
5. Sintering dies ndi zina
Pogwiritsa ntchito kusintha pang'ono kwa kutentha kwa zinthu zopangira graphite, ma sintering molds ndi ma brackets a transistors amatha kupangidwa. Tsopano imagwiritsidwa ntchito kwambiri ndipo yakhala chinthu chofunikira kwambiri pakukula kwa makampani opanga ma semiconductor. Kuphatikiza apo, ma graphite molds amagwiritsidwanso ntchito mu ma cast iron molds, ma cast iron okhazikika amitundu yosiyanasiyana ya zitsulo zopanda ferrous, ma cast iron molds, ma cast iron molds a zitsulo zosatentha (monga titaniyamu, zirconium, molybdenum, ndi zina zotero), ndi ma cast iron a aluminothermic welding for welding rails, ndi zina zotero.
6. Zipangidwe za graphite zogwiritsira ntchito poponya centrifugal
Graphite ya nkhungu yagwiritsidwa ntchito bwino popangira zinthu za centrifugal. Dziko la United States lagwiritsa ntchito ziboliboli zopangidwa ndi graphite zokhala ndi makulidwe opitilira mamilimita 25 popangira zinthu za mkuwa. Pofuna kupewa kuwonongeka kwa ziboliboli zopangidwa ndi graphite, njira zina zotsutsana ndi okosijeni zitha kutengedwa. Pambuyo popangira zinthu zingapo, ngati mkati mwa chiboliboli mwapezeka kuti mwapsa, kukula kwa dzenje lamkati la chiboliboli kumatha kukulitsidwa kuti kugwiritsidwe ntchito popanga zinthu zazikulu. Qingdao Mingyuan Fengyue New Materials ndi mtundu watsopano wa kampani yopangira zinthu za graphite yokhala ndi ufa wa graphite wapamwamba kwambiri ngati thupi lake lalikulu komanso zinthu zapamwamba za graphite ngati chinthu chotsogola. Yakhazikitsa ubale wa nthawi yayitali ndi mayunitsi oposa 200 am'nyumba ndi akunja ndipo yayamikiridwa kwambiri ndi ogwiritsa ntchito ambiri.
Ufa wa graphite wa nanometer umapangidwa kuchokera ku graphite yachilengedwe ngati zinthu zopangira, yokonzedwa pogwiritsa ntchito zida zapadera zophwanyira makina komanso njira zapadera zopangira. Monga ufa wa graphite wa nanoscale, ufa wa graphite wa nanometer uli ndi ntchito zambiri chifukwa cha kukula kwake kochepa kwa tinthu tating'onoting'ono, kuchuluka kwa kaboni wambiri, komanso mafuta ambiri, mphamvu zamagetsi zambiri, kukana kutentha kwambiri, ndi zina zotero. Kugwiritsa ntchito ufa wa nano-graphite kuli m'magawo opanga mafakitale monga mafuta ndi mphamvu zamagetsi.
Tinthu ta nanometer graphite ndi tabwino ndipo tili ndi tinthu tating'onoting'ono tabwino. Timapanga gawo loteteza lolimba komanso losavala lomwe limalumikizidwa ndi mankhwala pamwamba pa chitsulo. Titha kusakanizanso ndi zinthu zosagwiritsa ntchito mphamvu monga ma resini ndi zinthu za rabara ndi pulasitiki kuti tipange zinthu zophatikizana. Nanometer graphite ingapangidwenso kukhala zophimba zophatikizana. Zophimba zophatikizana zomwe zimapezeka powonjezera zodzaza mphamvu zimakhala ndi mphamvu zamagetsi zolimba komanso zokhazikika. Zili ndi ubwino wa kutentha kwabwino, kuyendetsa bwino kwamagetsi komanso kukana dzimbiri kwambiri. Nanometer graphite ili ndi kukula kofanana kwa tinthu tating'onoting'ono, kuyera kwambiri, komanso ntchito yayikulu pamwamba. Imakhalanso ndi mphamvu zamagetsi komanso mafuta ambiri, komanso kukana kutentha kwambiri, kukana kuvala, komanso kukhazikika kwa mankhwala a ufa wa graphite. Chifukwa chake, kuchuluka kwa kugwiritsa ntchito ufa wa nanometer graphite ndi kwakukulu kwambiri m'mafakitale.
Kugwiritsa ntchito ufa wa nano-graphite pokonza mabatire osungiramo zinthu nakonso n’kofala kwambiri. Kuwonjezera nano-graphite m’mabatire ogwiritsidwa ntchito kungapangitse kuti mphamvu yawo yosungiramo zinthu ipitirire 90% ya yoyambayo ndikuwonjezera nthawi yawo yogwiritsira ntchito ndi chaka chimodzi. Izi zimapulumutsa kwambiri ndalama zogwiritsira ntchito mabatire osungiramo zinthu ndipo zimathandizanso kwambiri pakuwongolera kuipitsidwa kwa mabatire komanso kuteteza chilengedwe.
Ufa wa graphite uli ndi ntchito zosiyanasiyana m'mafakitale. Ungagwiritsidwe ntchito m'mafakitale osiyanasiyana opanga zinthu. Kugwiritsa ntchito ufa wa graphite mosiyanasiyana kumabweretsa mitengo yosiyana. Ufa wa graphite uli ndi zotsatira zabwino zogwiritsidwa ntchito m'mafakitale monga mafuta odzola, zitsulo, kuyendetsa bwino zinthu, ndi zinthu zotsutsa. Zinthu monga kugwiritsa ntchito, kukula kwa tinthu tating'onoting'ono, ndi mtundu wa ufa wa graphite zonse zingakhudze mtengo wake.
Kagwiritsidwe ntchito ka ufa wa graphite ndi kosiyanasiyana, kotero pali mitundu yambiri ya ufa wa graphite. Mitundu yosiyanasiyana ya ufa wa graphite ili ndi mitengo yosiyana. Graphite yophwanyika imatha kukonzedwa kukhala ufa wa graphite wosiyanasiyana malinga ndi zofunikira ndi kukula kwa tinthu pogwiritsa ntchito zida zosiyanasiyana zophwanyira ndi njira zopangira. Monga wopanga ufa wa graphite, zofunikira za ufa wa graphite wopangidwa zimayambira pa maukonde 80 mpaka maukonde 15000. Ufa wa graphite uli ndi zofunikira zosiyanasiyana ndi kukula kwa tinthu, komanso mtengo wake. Pambuyo pokonzedwa pogwiritsa ntchito njira zopangira, ufa wa graphite uli ndi mafuta abwino kwambiri, kukana kutentha kwambiri, kuyendetsa magetsi, kukana dzimbiri, ndi zina zotero. Ufa wa graphite ukhozanso kugwira ntchito zofanana m'magawo osiyanasiyana opanga mafakitale.
Mitundu ya ufa wa graphite ndi monga: Ufa wa graphite wopindika, ufa wa graphite wopyapyala kwambiri, ufa wa nano graphite, graphite wopyapyala, graphite wotambasuka, graphite wopyapyala, graphite wopyapyala, ndi zina zotero, ufa wonse wa graphite umakonzedwa ndi njira zosiyanasiyana zopangira, ndipo ntchito zake zimakhala zosiyanasiyana. Ufa wa graphite umagwiritsidwa ntchito popanga mafuta opaka, mafuta olimba, zophikira za graphite, njerwa zotsalira, ma electrode a graphite, maburashi, ma electrode opanda batri, ndi zina zotero. Zonsezi zili ndi ntchito zabwino kwambiri.
