Kugwiritsa ntchito kwakukulu kwa zinthu za graphite

Zinthu zopangidwa ndi graphite zimatha kutulutsa kuwala kwa infrared kutali zikatenthedwa.

Njerwa ya magnesium-carbon Refractory ya magnesium-carbon ndi pakati pa nthawiyo, yomwe idapangidwa ndi United States, makampani opanga zitsulo aku Japan adayamba kugwiritsa ntchito njerwa ya magnesium-carbon poziziritsa madzi mu uvuni wa arc. Njerwa za Magnesia-carbon zakhala zikugwiritsidwa ntchito kwambiri popanga zitsulo padziko lonse lapansi ndipo zakhala zikugwiritsidwa ntchito mwachikhalidwe ndi graphite. Kumayambiriro kwa zaka khumi, njerwa za magnesium-carbon zinayamba kugwiritsidwa ntchito popanga chosinthira mpweya chomwe chimapangidwa pamwamba.

Njerwa ya aluminiyamu ya kaboni, zinthu zoyezera kaboni za aluminiyamu zimagwiritsidwa ntchito kwambiri popanga zinthu zopitilira muyeso, chivundikiro cha mpanda chokhazikika cha chitsulo chokhazikika, nozzle ya pansi pa madzi ndi silinda yophulitsira mafuta. Chitsulo chopangidwa ndi kupangidwa kopitilira muyeso ku Japan chimapanga zoposa kupanga konse.

Zinthu zophimbidwa ndi graphite ndi zinthu zina zokhudzana nazo, monga crucible, botolo la khosi lopindika, pulagi ndi nozzle, ndi zina zotero, zimakhala ndi kukana kwakukulu kwa moto, kutentha kochepa, njira yosungunula zitsulo, chifukwa cha kulowa kwa chitsulo ndi kukokoloka, zimakhalanso zokhazikika, kutentha kokhazikika bwino kutentha kutentha kwambiri komanso kuyendetsa bwino kwambiri, Chifukwa chake, graphite crucible ndi zinthu zina zokhudzana nazo zimagwiritsidwa ntchito kwambiri posungunula chitsulo mwachindunji. Dongo lophimbidwa ndi graphite limapangidwa ndi kaboni wochuluka kuposa graphite yopingasa, nthawi zambiri sikelo ya graphite iyenera kukhala yayikulu kuposa mesh (- screen), ndipo kusintha kwakukulu muukadaulo wopanga crucible wakunja ndikuti mtundu wa graphite womwe umagwiritsidwa ntchito, kukula kwa sikelo ndi mtundu wake zimakhala ndi kusinthasintha kwakukulu kutsatiridwa ndi kugwiritsa ntchito silicon carbide graphite crucible m'malo mwa dongo lophimbidwa ndi graphite. Izi zimachitika chifukwa cha kuyambitsa ukadaulo wopanikizika nthawi zonse mumakampani opanga zitsulo. Kugwiritsa ntchito ukadaulo wopanikizika nthawi zonse kungapangitsenso kuti graphite yaying'ono igwiritsidwe ntchito, mu graphite yadongo, ndipo mu silicon carbide graphite crucible, kuchuluka kwa zigawo zazikulu kumangowerengera, ndipo kuchuluka kwa kaboni mu graphite kumachepetsedwa kufika pa.

kupanga zitsulo

Graphite ndi zinthu zina zodetsedwa zingagwiritsidwe ntchito ngati ma carburizer mumakampani opanga zitsulo. Carburizing imagwiritsa ntchito zinthu zosiyanasiyana za carbonaceous, kuphatikizapo graphite yopangira, petroleum coke, metallurgical coke ndi natural graphite. Graphite ikadali imodzi mwa ntchito zazikulu za graphite yofanana ndi dziko lapansi padziko lonse lapansi.

Zinthu zoyendetsera

Graphite imagwiritsidwa ntchito kwambiri m'makampani amagetsi monga ma electrode, maburashi, ndodo za kaboni, machubu a kaboni, zobwezeretsa mercury, ma gasket a graphite, zida za foni, zokutira machubu apa TV ndi zina zotero. Pakati pawo, graphite electrode ndiyo yomwe imagwiritsidwa ntchito kwambiri, posungunula zitsulo zosiyanasiyana za alloy, alloy yachitsulo, kugwiritsa ntchito graphite electrode, kenako mphamvu yamphamvu kudzera mu electrode kupita ku malo osungunuka a ng'anjo, kupanga arc, kotero kuti mphamvu yamagetsi ipange mphamvu yotentha, kutentha kumakwera kufika pafupifupi, kuti akwaniritse cholinga chosungunula kapena kuchitapo kanthu. Kuphatikiza apo, popereka magnesium, aluminiyamu ndi sodium mu electrolyte, anode ya selo ya electrolytic imagwiritsanso ntchito graphite electrode. Graphite electrode imagwiritsidwanso ntchito ngati zinthu zoyendetsera ng'anjo popanga ng'anjo zotsutsana ndi abrasive. Graphite yomwe imagwiritsidwa ntchito m'makampani amagetsi ili ndi zofunikira zazikulu pakukula kwa tinthu tating'onoting'ono ndi kalasi. Monga mabatire a alkaline ndi zinthu zina zapadera zamagetsi, kukula kwa tinthu ta graphite kumafunika kulamulidwa mkati mwa ntchitoyo, kalasi ili pamwamba, ndipo zonyansa zovulaza (makamaka chitsulo chachitsulo) ziyenera kukhala pansi. Graphite yomwe imagwiritsidwa ntchito mu chubu cha zithunzi za pa TV ili ndi zofunikira zotsatirazi pakukula kwa tinthu tating'onoting'ono. Graphite nthawi zambiri imagwiritsidwa ntchito ngati mafuta odzola mumakampani opanga makina. Mafuta odzola nthawi zambiri sangagwiritsidwe ntchito pa liwiro lalikulu, kutentha kwambiri, mikhalidwe yopanikizika kwambiri, ndipo zinthu zosagwira ntchito za graphite zimatha kugwira ntchito popanda mafuta odzola pa kutentha komanso pa liwiro lalikulu kwambiri. Zipangizo zambiri zotumizira zinthu zowononga, zinthu za graphite zomwe zimagwiritsidwa ntchito kwambiri zopangidwa ndi mphete za pistoni, zisindikizo ndi ma bearing, zikayenda, sizifunikira kuwonjezera mafuta odzola, mkaka wa graphite ndi mafuta abwino opangira zitsulo zambiri (zojambula za waya, zojambula za chubu).

Zinthu zosagwira dzimbiri

Graphite ili ndi kukhazikika kwabwino kwa mankhwala. Graphite yokonzedwa mwapadera ili ndi mawonekedwe okana dzimbiri, kuyendetsa bwino kutentha komanso kutsika kwa mpweya, ndipo imagwiritsidwa ntchito kwambiri popanga zosinthira kutentha, matanki ochitirapo kanthu, zoziziritsira, nsanja zoyaka, nsanja zoyatsira, zoziziritsira, zotenthetsera, zosefera, mapampu ndi zida zina. Zipangizozi zimagwiritsidwa ntchito mu petrochemical, hydrometallurgy, kupanga asidi ndi alkali, ulusi wopangidwa, mapepala ndi mafakitale ena, zimatha kusunga zinthu zambiri zachitsulo. 0 Popangira zinthu zopangira zitsulo, kupukuta, kukanikiza ndi kutentha kwambiri chifukwa cha kuchuluka kochepa kwa graphite, komanso kuthekera kosintha kuzizira ndi kutentha, zingagwiritsidwe ntchito ngati nkhungu yagalasi, mutagwiritsa ntchito graphite, zinthu zopangira zitsulo zakuda zomwe zapezeka kukula kolondola, pamwamba pake posalala, zokolola zambiri, zingagwiritsidwe ntchito popanda kukonzedwa kapena kukonzedwa pang'ono, motero zimasunga zitsulo zambiri. Kupanga kwa carbide ndi njira zina zopangira zitsulo za ufa, nthawi zambiri zimapangidwa ndi zipangizo za graphite kuti zisamavutike ndi kupsinjika kwa maboti. Chomera chokulirapo cha silicon crystal, choyeretsera chachigawo, cholumikizira, chotenthetsera, chotenthetsera choyatsira, ndi zina zotero, zimakonzedwa ndi graphite yoyera kwambiri. Kuphatikiza apo, graphite ingagwiritsidwenso ntchito ngati mbale yotetezera zitsulo za vacuum graphite ndi maziko, chubu cha ng'anjo yotenthetsera kutentha kwambiri, ndodo, mbale, gululi ndi zina.

Mphamvu ya atomiki

Graphite ili ndi mphamvu yabwino yochepetsera kufalikira kwa neutron, yoyamba ngati chowongolera chomwe chimagwiritsidwa ntchito mu ma reactor a atomiki, uranium-graphite reactor ndi riyakitala ya atomiki yomwe imagwiritsidwa ntchito kwambiri. Monga mphamvu ya zinthu zochepetsera kufalikira kwa mphamvu ya atomiki ziyenera kukhala ndi malo osungunuka kwambiri, kukhazikika, kukana dzimbiri, graphite ikhoza kukwaniritsa zofunikira zomwe zili pamwambapa. Kuyera kwa graphite komwe kumagwiritsidwa ntchito ngati riyakitala ya atomiki ndi kwakukulu kwambiri, ndipo kuchuluka kwa kuipitsidwa sikuyenera kupitirira makumi angapo (gawo limodzi pa miliyoni), makamaka kuchuluka kwa boron kuyenera kukhala kochepera.
