Ukusetshenziswa okuyinhloko kwemikhiqizo ye-graphite

Imikhiqizo ye-graphite ingakhulula imisebe ye-infrared ekude ngemva kokushisisa.

I-Magnesium-carbon brick refractory I-Magnesium-carbon refractory iphakathi nenkathi, eyathuthukiswa yi-United States, imboni yaseJapane yokwenza insimbi yaqala ukusebenzisa isitini se-magnesium-carbon ukuncibilikisa amanzi okupholisa isithando se-arc. Izitini ze-Magnesia-carbon ziye zasetshenziswa kabanzi ekwenzeni insimbi emhlabeni wonke futhi seziyindlela evamile yokusetshenziswa kwe-graphite. Ekuqaleni kweshumi leminyaka, izitini ze-magnesium-carbon zaqala ukusetshenziselwa ulwelwesi lwesiguquli esiphephezelwa phezulu komoyampilo.

Izinto ze-aluminium carbon brick refractory carbon refractory zisetshenziswa kakhulu ekubunjweni okuqhubekayo, isembozo senqaba yensimbi eyisicaba ye-billet ezibeka endaweni eyodwa, umlomo wombhobho ongaphansi kwamanzi nesilinda somthombo kawoyela oqhumayo. Insimbi ekhiqizwa ngokusakazwa okuqhubekayo e-Japan yenza ngaphezu kokukhiqizwa okuphelele.

Imikhiqizo e-crucible nehlobene eyenziwe nge-graphite ukubunjwa kanye ne-refractory crucible kanye nemikhiqizo ehlobene, efana ne-crucible, ibhodlela lentamo egobile, ipulaki ne-nozzle, njll., inokumelana nomlilo ophezulu, ukunwetshwa okushisayo okuphansi, inqubo yensimbi encibilikayo, ngokungena kwensimbi nokuguguleka nakho. ezinzile, ukuzinza okuhle kokushaqeka okushisayo ekushiseni okuphezulu kanye ne-conductivity enhle kakhulu, Ngakho-ke, i-graphite crucible kanye nemikhiqizo yayo ehlobene isetshenziswa kabanzi ohlelweni lokuncibilika okuqondile kwensimbi. I-crucible yobumba ye-graphite yendabuko ikhiqizwa ngokuqukethwe kwekhabhoni okukhulu kune-graphite yesikali, ngokuvamile isikali se-graphite kufanele sibe sikhulu kune-mesh (- isikrini), futhi ukuthuthukiswa okubalulekile kobuchwepheshe bokukhiqiza be-crucible bangaphandle ukuthi uhlobo lwe-graphite olusetshenzisiwe, isikali. usayizi kanye nekhwalithi inokuguquguquka okukhulu okulandelwa ukusetshenziswa kwe-silicon carbide graphite crucible esikhundleni se-crucible yobumba ye-graphite crucible. Lokhu kungenxa yokwethulwa kobuchwepheshe bokucindezela njalo embonini yokwenza insimbi. Ukusetshenziswa kobuchwepheshe bengcindezi eqhubekayo kungenza futhi i-graphite encane isetshenziswe, ku-clay graphite crucible, naku-silicon carbide graphite crucible, okuqukethwe kwezingxenye ezinkulu ze-akhawunti kuphela, futhi okuqukethwe kwekhabhoni ye-graphite kuncishisiwe.

ukwenza insimbi

I-graphite nezinye izinto ezingcolile zingasetshenziswa njengama-carburizers embonini yokwenza insimbi. I-Carburizing isebenzisa izinhlobonhlobo zezinto ze-carbonaceous, ezihlanganisa i-graphite yokwenziwa, i-petroleum coke, i-coke ye-metallurgical kanye ne-graphite yemvelo. I-graphite isengenye yezinto ezisetshenziswa kakhulu ze-graphite efana nomhlaba emhlabeni.

Izinto zokuqhuba

I-graphite isetshenziswa kakhulu embonini kagesi njengama-electrode, amabhulashi, izinduku zekhabhoni, amashubhu ekhabhoni, ama-mercury rectifiers, ama-graphite gaskets, izingxenye zocingo, i-TV picture tube coating nokunye. Phakathi kwazo, i-graphite electrode iyona esetshenziswa kakhulu, ekuncibilikisweni kwensimbi ehlukahlukene yengxubevange, ingxubevange yensimbi, ukusetshenziswa kwe-graphite electrode, bese kuba namandla anamandla ngokusebenzisa i-electrode endaweni yokuncibilika kwesithando somlilo, ikhiqize i-arc, ukuze amandla kagesi angene. amandla okushisa, izinga lokushisa likhuphuka lifinyelele cishe cishe, ukuze kufezwe injongo yokuncibilika noma ukusabela. Ngaphezu kwalokho, lapho i-electrolyzing magnesium, i-aluminium ne-sodium, i-anode yeseli ye-electrolytic nayo isebenzisa i-graphite electrode. I-electrode ye-graphite iphinde isetshenziswe njengento eqhubayo yekhanda lesithando sokukhiqiza izithando zomlilo ezivuthayo. I-graphite esetshenziswa embonini kagesi inezidingo eziphezulu zosayizi wezinhlayiyana kanye nebanga. Njengamabhethri e-alkaline neminye imikhiqizo yekhabhoni kagesi ekhethekile, usayizi wezinhlayiyana zegraphite kuyadingeka ukuthi ulawulwe ngaphakathi kobubanzi bephrojekthi, ibanga lingaphezulu, futhi ukungcola okuyingozi (ikakhulukazi insimbi yensimbi) kuyadingeka ukuthi kube ngaphansi. I-graphite esetshenziswe kushubhu yezithombe ze-TV inezidingo zosayizi wezinhlayiyana ezilandelayo. I-graphite ivame ukusetshenziswa njengento yokugcoba embonini yemishini. Amafutha okugcoba ngokuvamile awakwazi ukusetshenziswa ngaphansi kwejubane eliphezulu, izinga lokushisa eliphezulu, izimo zengcindezi ephezulu, nezinto ezikwazi ukumelana ne-graphite zingasebenza ngaphandle kokugcoba uwoyela - izinga lokushisa kanye nesivinini esikhulu sokushelela. Imishini eminingi yokuthutha imidiya egqwalayo, izinto ezisetshenziswa kabanzi ze-graphite ezenziwe ngamasongo e-piston, ama-seal kanye nama-bearings, lapho zigijima, azidingi ukwengeza amafutha okugcoba, ubisi lwe-graphite lubuye lube lubricant oluhle lokucutshungulwa kwensimbi eminingi (umdwebo wocingo, umdwebo weshubhu).

Izinto ezimelana nokubola

I-graphite inokusimama okuhle kwamakhemikhali. I-graphite ecutshungulwe ngokukhethekile inezici zokumelana nokugqwala, ukuguquguquka okuhle kokushisa kanye nokungena okuncane, futhi isetshenziswa kabanzi ekukhiqizeni ama-heaters, amathangi okusabela, ama-condensers, imibhoshongo evuthayo, imibhoshongo yokumuncwa, ama-cooler, ama-heaters, izihlungi, amaphampu nezinye izinto zokusebenza. Le mishini isetshenziselwa ukukhiqizwa kwe-petrochemical, i-hydrometallurgy, i-asidi ne-alkali, i-synthetic fiber, iphepha kanye neminye imikhakha yezimboni, ingasindisa izinto eziningi zensimbi. 0 Ukuze uphonsa, u-sanding, ucindezela kanye nokushisa okuphezulu kwe-metallurgical materials ngenxa ye-coefficient encane yokwandisa ye-graphite, nekhono lokushintsha amakhaza nokushisa, ingasetshenziswa njengesikhunta seglasi, ngemva kokusetshenziswa kwe-graphite, ukubunjwa kwensimbi emnyama etholakalayo. usayizi onembile, ubuso obushelelezi, isivuno esiphezulu, singasetshenziswa ngaphandle kokucubungula noma ukucutshungulwa kancane, ngaleyo ndlela kugcinwe insimbi eningi. Ukukhiqizwa kwe-carbide nezinye izinqubo ze-powder metallurgy, ngokuvamile ezenziwe ngezinto ze-graphite zokumelana nokucindezela ekungeneni kwezikebhe. I-Monocrystalline silicon crystal growth crucible, umkhumbi wokucwenga wesifunda, ubakaki, into elungiswayo, i-heater yokungeniswa, njll., icutshungulwa ngegraphite emsulwa. Ngaphezu kwalokho, i-graphite ingasetshenziswa njenge-vacuum metallurgy graphite insulation plate kanye nesisekelo, ukushisa okuphezulu kokumelana nokushisa kwesithando somlilo, induku, ipuleti, igridi nezinye izingxenye.

Amandla e-athomu

I-graphite inokusebenza okuhle kokuncishiswa kwe-neutron, eyokuqala njengemodareyitha esetshenziswa kuma-athomu asabelayo, i-uranium-graphite reactor iyireactor esetshenziswa kakhulu ye-athomu. Njengamandla we-atomic energy reactor deceleration impahla kufanele ibe nendawo ephezulu yokuncibilika, ukuzinza, ukumelana nokugqwala, i-graphite ingahlangabezana ngokugcwele nezidingo ezingenhla. Ukuhlanzeka kwe-graphite esetshenziswa njenge-reactor ye-athomu kuphezulu kakhulu, futhi okuqukethwe kokungcola akufanele kudlule inqwaba (ingxenye eyodwa ngesigidi), ikakhulukazi okuqukethwe kwe-boron kufanele kube ngaphansi.

I-anti-fouling ne-anti-rust

I-graphite ingavimbela ukukala kwe-boiler, ukuhlolwa kweyunithi efanele kubonisa ukuthi ukwengeza inani elithile le-graphite powder emanzini (cishe ithani ngalinye lamanzi) kungavimbela isikali endaweni yokubhayela. Ngaphezu kwalokho, i-graphite isetshenziswa koshimula bensimbi, uphahla, amabhuloho, amapayipi angaba anti-corrosion kanye nokugqwala.

Okunye ukusetshenziswa

Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, abantu baye bathuthukisa ukusetshenziswa okuningi okusha kwegraphite. Imikhiqizo ye-graphite eguquguqukayo. I-Flexible graphite, eyaziwa nangokuthi i-graphite eyandisiwe, iwumkhiqizo omusha we-graphite owakhiwa ngawo-1990. I-United States icwaninge ngempumelelo izinto zokuvala uphawu ze-graphite eziguquguqukayo ukuze kuxazululwe inkinga yokuvuza kwamavalvu wamandla e-athomu, kwase kuthi iJalimane, iJapan neFrance nayo yaqala ukuthuthukisa nokukhiqiza. Ngaphezu kwezici ze-graphite yemvelo, lo mkhiqizo unokuguquguquka okukhethekile nokunwebeka. Ngakho-ke, iyinto efanelekile yokuvala uphawu. Isetshenziswa kabanzi ku-petrochemical, amandla e-athomu nakweminye imikhakha yezimboni. Isidingo semakethe yamazwe ngamazwe siyakhula unyaka nonyaka.

Imikhiqizo yokuhlanzeka okuphezulu isetshenziswa ekuncibilikiseni insimbi ehlanzekile, embonini ye-elekthronikhi, embonini yenuzi kanye nokukhiqizwa kwesikhunta; Imikhiqizo evamile isetshenziswa ethangini le-aluminium electrolysis, isithando somlilo se-powder metallurgy sintering, isithando somlilo se-ferroalloy nezinye izinto zokwakha zesithando somlilo wamaminerali.

Inkampani yethu ingahlinzeka amakhasimende ngezinhlobo ezahlukene zemikhiqizo ye-graphite eyimishini, wamukelekile ukunikeza imidwebo ngokwezifiso okukhethekile. Muva nje, inkampani yethu ihlinzeke ngemikhiqizo eyenziwe ngezifiso ye-graphite bushing kumakhasimende amadala, ngokuya ngemidwebo nezidingo ezinikezwe amakhasimende amadala, ikhwalithi kanye nobuningi, eqediwe ngesikhathi futhi ilethwe njengoba kuthenjisiwe, ngethemba lokuwina ukwethenjwa kwamakhasimende amaningi ngobungcweti nobuqotho bethu. .
