Ukusetshenziswa okuyinhloko kwemikhiqizo ye-graphite

Imikhiqizo ye-graphite ingakhipha imisebe ye-infrared ekude ngemva kokushisa.

Isitini se-magnesium-carbon I-Magnesium-carbon refractory iphakathi nenkathi, eyasungulwa yi-United States, imboni yokwenza insimbi yaseJapan yaqala ukusebenzisa isitini se-magnesium-carbon ekupholiseni amanzi nge-arc furnace smelting. Izitini ze-Magnesia-carbon ziye zasetshenziswa kabanzi ekwenzeni insimbi emhlabeni wonke futhi seziye zaba ukusetshenziswa kwendabuko kwe-graphite. Ekuqaleni kwale minyaka eyishumi, izitini ze-magnesium-carbon zaqala ukusetshenziswa njengendwangu yesiguquli se-oxygen esiphezulu.

Izinto ezisetshenziswa kakhulu ekubunjweni okuqhubekayo, isivalo sepayipi eliyindilinga eliyindilinga eliyindilinga eliyindilinga, i-nozzle engaphansi kwamanzi kanye nesilinda sokuqhuma komthombo wamafutha. Insimbi ekhiqizwa ngokubunjwa okuqhubekayo eJapane ingaphezu komkhiqizo ophelele.

Imikhiqizo ye-Crucible kanye nemikhiqizo ehlobene eyenziwe ngokubumba kwe-graphite kanye ne-crucible ephikisayo kanye nemikhiqizo ehlobene nayo, njenge-crucible, ibhodlela lentamo egobile, ipulaki kanye ne-nozzle, njll., inokumelana okukhulu nomlilo, ukwanda okuphansi kokushisa, inqubo yokuncibilikisa insimbi, ngokungena kwensimbi nokuguguleka kwayo nakho kuzinzile, ukuzinza okuhle kokushaqeka kokushisa ekushiseni okuphezulu kanye nokuqhuba kahle kakhulu, Ngakho-ke, i-graphite crucible kanye nemikhiqizo yayo ehlobene nayo isetshenziswa kabanzi enqubweni yokuncibilikisa insimbi ngqo. I-crucible yendabuko yobumba be-graphite yenziwa ngokuqukethwe kwekhabhoni okukhulu kune-graphite yesikali, ngokuvamile isikali se-graphite kufanele sibe sikhulu kune-mesh (- isikrini), futhi ukuthuthuka okubalulekile kubuchwepheshe bokukhiqiza i-crucible yangaphandle ukuthi uhlobo lwe-graphite esetshenziswayo, usayizi wesikali kanye nekhwalithi kunokuguquguquka okukhulu okulandelwa ukusetshenziswa kwe-silicon carbide graphite crucible esikhundleni se-crucible yendabuko ye-graphite yobumba. Lokhu kungenxa yokwethulwa kobuchwepheshe bokucindezela obuqhubekayo embonini yokwenza insimbi. Ukusetshenziswa kobuchwepheshe bokucindezela okuqhubekayo kungenza futhi i-graphite encane ingasetshenziswa, endaweni yobumba ye-graphite, kanye nendawo yobumba ye-silicon carbide, okuqukethwe kwezingxenye ezinkulu kubalwa kuphela, futhi okuqukethwe kwe-carbon kwe-graphite kuncishisiwe kube.

ukwenza insimbi

I-Graphite nezinye izinto zokungcola zingasetshenziswa njengezinto zokugaya izinsimbi embonini yokwenza insimbi. I-Carburizing isebenzisa izinto eziningi ze-carbonaceous, okuhlanganisa i-graphite yokwenziwa, i-petroleum coke, i-metallurgical coke kanye ne-graphite yemvelo. I-Graphite isengenye yezindlela eziyinhloko zokusebenzisa i-graphite efana nomhlaba emhlabeni.

Izinto eziqhuba ugesi

I-Graphite isetshenziswa kabanzi embonini kagesi njengama-electrode, amabhulashi, izinduku zekhabhoni, amashubhu ekhabhoni, ama-rectifier e-mercury, ama-gasket e-graphite, izingxenye zocingo, i-television picture tube coating njalo njalo. Phakathi kwazo, i-graphite electrode iyona esetshenziswa kakhulu, ekuncibilikiseni insimbi ehlukahlukene ye-alloy, i-iron alloy, ukusetshenziswa kwe-graphite electrode, bese kuba ugesi onamandla nge-electrode uye endaweni yokuncibilikisa isithando, kukhiqize i-arc, ukuze amandla kagesi abe amandla okushisa, izinga lokushisa likhuphuke liye cishe, ukuze kufezwe injongo yokuncibilika noma ukusabela. Ngaphezu kwalokho, lapho kusetshenziswa i-electrolyze ye-magnesium, i-aluminium kanye ne-sodium nge-electrode, i-anode yeseli le-electrolytic nayo isebenzisa i-graphite electrode. I-graphite electrode isetshenziswa futhi njengento eqhuba ikhanda lesithando ukuze kukhiqizwe izithando zokumelana nokuklwebheka. I-graphite esetshenziswa embonini kagesi inezidingo eziphezulu zosayizi wezinhlayiya kanye nezinga. Njengamabhethri e-alkaline kanye neminye imikhiqizo ekhethekile yekhabhoni kagesi, usayizi wezinhlayiya ze-graphite uyadingeka ukuthi ulawulwe ngaphakathi kobubanzi bephrojekthi, izinga lingaphezulu, futhi ukungcola okulimazayo (ikakhulukazi insimbi yensimbi) kuyadingeka kube ngaphansi. I-graphite esetshenziswa kushubhu lesithombe se-TV inezidingo ezilandelayo zosayizi wezinhlayiya. I-Graphite ivame ukusetshenziswa njengesithambisi embonini yemishini. Uwoyela wokugcoba uvame ukusetshenziswa ngaphansi kwesivinini esiphezulu, izinga lokushisa eliphezulu, izimo zokucindezela okuphezulu, kanye nezinto ezingagugi ze-graphite zingasebenza ngaphandle kokugcoba uwoyela ezingeni lokushisa eliphezulu nangesivinini esikhulu kakhulu sokushelela. Imishini eminingi yokudlulisa imithombo ebolile, izinto ze-graphite ezisetshenziswa kabanzi ezenziwe ngamasongo e-piston, izivalo nama-bearings, lapho zisebenza, azidingi ukwengeza uwoyela wokugcoba, ubisi lwe-graphite luphinde lube isithambisi esihle sokucubungula insimbi eminingi (ukudweba ngocingo, ukudweba ngeshubhu).

Izinto ezingamelani nokugqwala

I-Graphite inokuqina okuhle kwamakhemikhali. I-graphite ecutshungulwe ngokukhethekile inezici zokumelana nokugqwala, ukuqhuba kahle kokushisa kanye nokuvuleka okuphansi, futhi isetshenziswa kabanzi ekukhiqizweni kwezishintshi zokushisa, amathangi okusabela, ama-condenser, imibhoshongo yokushisa, imibhoshongo yokumunca, ama-cooler, ama-heater, izihlungi, amaphampu neminye imishini. Le mishini isetshenziswa ekukhiqizeni i-petrochemical, i-hydrometallurgy, i-asidi kanye ne-alkali, i-fibre yokwenziwa, iphepha kanye neminye imikhakha yezimboni, ingonga izinto eziningi zensimbi. 0 Zokuphonsa, ukusantinga, ukucindezela kanye nezinto ze-metallurgical ezishisa kakhulu ngenxa ye-coefficient encane yokwandisa ye-graphite, kanye nekhono lokushintsha ukubanda nokushisa, zingasetshenziswa njengesikhunta sengilazi, ngemuva kokusebenzisa i-graphite, ukuthungwa kwensimbi emnyama okutholwe usayizi onembile, indawo ebushelelezi, isivuno esikhulu, kungasetshenziswa ngaphandle kokucutshungulwa noma ukucutshungulwa kancane, ngaleyo ndlela konga insimbi eningi. Ukukhiqizwa kwe-carbide nezinye izinqubo ze-powder metallurgy, ngokuvamile ezenziwe ngezinto ze-graphite zokumelana nokucindezela ekushiseni izikebhe. I-monocrystalline silicon crystal growth crucible, isikebhe sokucwenga sesifunda, i-bracket, i-fixture, i-induction heater, njll., zicutshungulwa nge-graphite emsulwa kakhulu. Ngaphezu kwalokho, i-graphite ingasetshenziswa futhi njenge-vacuum metallurgy graphite insulation plate kanye nesisekelo, ishubhu lesithando somlilo esimelana nokushisa okuphezulu, induku, ipuleti, igridi nezinye izingxenye.

Amandla e-athomu

I-Graphite inokusebenza okuhle kokunciphisa i-neutron, eyokuqala njenge-moderator esetshenziswa kuma-reactor e-athomu, i-uranium-graphite reactor iyi-athomu reactor esetshenziswa kabanzi. Njengoba amandla e-athomu e-athomu e-athomu enciphisa i-reactor kufanele abe nephuzu eliphezulu lokuncibilika, ukuzinza, ukumelana nokugqwala, i-graphite ingahlangabezana ngokugcwele nezidingo ezingenhla. Ubumsulwa be-graphite esetshenziswa njenge-athomu reactor buphakeme kakhulu, futhi okuqukethwe kokungcola akufanele kudlule amashumi (ingxenye eyodwa ngesigidi), ikakhulukazi okuqukethwe kwe-boron kufanele kube ngaphansi.

Izinto ezilwa nokungcola kanye nokugqwala

I-Graphite ingavimbela ukukhushulwa kwebhoyila, izivivinyo zeyunithi ezifanele zibonisa ukuthi ukufaka inani elithile lempuphu ye-graphite emanzini (cishe ngethani ngalinye lamanzi) kungavimbela ukukhushulwa kwebhoyila. Ngaphezu kwalokho, i-graphite esetshenziswa kuma-chimney ensimbi, ophahleni, emabhuloho, emapayipini ingaba nomthelela wokulwa nokugqwala kanye nokugqwala.

Okunye ukusetshenziswa

Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, abantu bathuthukise ukusetshenziswa okuningi okusha kwe-graphite. Imikhiqizo ye-graphite eguquguqukayo. I-graphite eguquguqukayo, eyaziwa nangokuthi i-expanded graphite, ingumkhiqizo omusha we-graphite owasungulwa ngawo-1990. I-United States yacwaninga ngempumelelo izinto zokuvala i-graphite eguquguqukayo ukuxazulula inkinga yokuvuza kwama-valve wamandla e-athomu, kwathi iJalimane, iJapan neFrance nazo zaqala ukuthuthukisa nokukhiqiza. Ngaphezu kwezici ze-graphite yemvelo, lo mkhiqizo unokuguquguquka okukhethekile kanye nokunwebeka. Ngakho-ke, uyinto efanelekile yokuvala. Isetshenziswa kabanzi ku-petrochemical, amandla e-athomu nakwezinye izinkambu zezimboni. Isidingo semakethe yamazwe ngamazwe siyakhula unyaka nonyaka.

Imikhiqizo yobumsulwa obuphezulu isetshenziswa ekuncibilikiseni insimbi ngobumsulwa obuphezulu, embonini ye-elekthronikhi, embonini yenuzi kanye nasekukhiqizweni kwesikhunta; Imikhiqizo evamile isetshenziswa ethangini le-aluminium electrolysis, esithandweni sokushisa insimbi esiyimpuphu, esithandweni se-ferroalloy nakwezinye izinto zokwakha izithando zamaminerali.
