Igraphite yokwenziwa yipolycrystalline efana necrystallography. Kukho iintlobo ezininzi zegraphite eyenziweyo kunye neenkqubo ezahlukeneyo zemveliso.
Ngomqondo obanzi, zonke izinto zegraphite ezifunyenwe emva kwe-carbonization yezinto eziphilayo kunye ne-graphitization kwiqondo lokushisa eliphezulu zingabizwa ngokudibeneyo njenge-graphite yokwenziwa, njenge-carbon (graphite) fiber, i-pyrolytic carbon (graphite), i-foam graphite, njl.
Ngengqiqo emxinwa, igraphite eyenziweyo idla ngokubhekisa kwizinto ezininzi eziqinileyo, ezifana negraphite electrode, isostatic graphite, eyenziwe ngokuxutywa, ukuxuba, ukubumba, i-carbonization (eyaziwa ngokuba kukurosa kwishishini) kunye negraphitization, kunye nomxholo ophantsi wokungcola wamalahle ekrwada. (i-petroleum coke, i-asphalt coke, njl. njl.) njenge-aggregate, i-coal pitch njengesibophelelo.
Kukho iindlela ezininzi zegraphite eyenziweyo, kubandakanya umgubo, ifayibha kunye nebhloko, ngelixa imvakalelo emxinwa yegraphite eyenziweyo idla ngokuba yibhloko, ekufuneka iqwalaselwe kwimilo ethile xa isetyenziswa. Inokuthi ithathwe njengoluhlobo lwezinto ezininzi, kubandakanywa isigaba segraphite esiguqulwa ngamasuntswana ekhabhoni afana nepetroleum coke okanye i-asphalt coke, isigaba segraphite esiguqulwa ngamalahle e-pitch binder ehlanganiswe ngamasuntswana, ukuqokelelwa kwamasuntswana okanye iipores ezenziwe ngamalahle. pitch binder emva konyango lobushushu, njl. Ngokuqhelekileyo, okukhona ubushushu bonyango lobushushu buphezulu, kokukhona iqondo eliphezulu legraphitization. Imveliso yeshishini yegraphite eyenziweyo, iqondo legraphitization lihlala lingaphantsi kwama-90%.
Xa kuthelekiswa negraphite yendalo, igraphite eyenziweyo inokudluliselwa kobushushu obubuthathaka kunye nokuhanjiswa kombane, ukuthambisa kunye neplastikhi, kodwa igraphite eyenziweyo inokumelana nokunxiba, ukumelana nokubola kunye nokungena kancinci kunegraphite yendalo.
Iimathiriyeli ekrwada ukuvelisa igraphite eyenziweyo ikakhulu ziquka petroleum coke, inaliti coke, asphalt coke, pitch amalahle, carbon microspheres, njl. Iimveliso zayo esezantsi kakhulu ziquka igraphite electrode, anode pre-baked, graphite isostatic, ubunyulu obuphezulu graphite, igraphite yenyukliya, ubushushu. umtshintshi kunye nokunye.
Ukusetyenziswa kwemveliso yegraphite eyenziweyo kubonakaliswa ikakhulu kule miba ilandelayo:
1. I-electrode ye-graphite: Nge-petroleum coke kunye nenaliti ye-coke njengezinto eziluhlaza kunye ne-coal pitch njenge-binder, i-electrode yegraphite yenziwe ngokubala, ukuxubha, ukuxuba, ukucinezela, ukugcoba, ukukrazula kunye nomatshini. Isetyenziswa ngokubanzi kwintsimbi yesithando somlilo, i-silicon yoshishino, i-phosphorus etyheli kunye nezinye izixhobo ngokukhupha amandla ombane ngendlela ye-arc ukutshisa kunye nokunyibilikisa intlawulo.
2. I-anode yokubhaka kwangaphambili: eyenziwe nge-petroleum coke njengento ekrwada kunye ne-coal pitch njenge-binder ngokusebenzisa i-calcination, i-batching, ukuxuba, ukucinezela, ukugcoba, ukufakwa, i-graphitization kunye ne-machining, isetyenziswa ngokubanzi njenge-anode conductive ye-electrolytic aluminium izixhobo.
3. Ukuthwala, ukutywina umsesane: ukuhambisa izixhobo zemidiya ezonakalisayo, igraphite eyenziwe ngokubanzi esetyenziswayo eyenziwe ngamakhonkco episton, amakhonkco okutywina kunye neebheringi, sebenza ngaphandle kokongeza ioli yokuthambisa.
4. Umtshintshi wokushisa, iklasi yokucoca: igraphite eyenziweyo ineempawu zokumelana ne-corrosion, i-conductivity efanelekileyo ye-thermal kunye ne-permeability ephantsi. Isetyenziswa ngokubanzi kwishishini lemichiza ukwenza umtshintshi wobushushu, itanki yokusabela, i-absorber, isihluzo kunye nezinye izixhobo.
5. I-graphite ekhethekileyo: kunye nekhwalithi ephezulu ye-petroleum coke njengento eluhlaza, i-coal pitch okanye i-resin yokwenziwa njenge-binder, ngokulungiselela izinto eziluhlaza, ukuxubha, ukuxova, ukuxinzelela, ukutyumza, ukuxuba ukuxova, ukubumba, ukugcoba okuninzi, ukungena ngokuphindaphindiweyo, ukuhlanjululwa kunye ne-graphitization, ukwenziwa komatshini kunye nokwenza, ngokubanzi kubandakanywa igraphite ye-isostatic, igraphite yenyukliya, igraphite yococeko oluphezulu, esetyenziswa kwi-aerospace, i-electronics, amacandelo oshishino lwenyukliya.
