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, i-graphite eyenziweyo idla ngokubhekisela kwizinto ezininzi eziqinileyo, ezifana ne-graphite electrode, i-isostatic graphite, eyenziwe ngokuxutywa, ukuxuba, ukubumba, i-carbonization (eyaziwa ngokuba yi-roasting kwi-industry) kunye ne-graphitization, kunye nomxholo ophantsi ongcolileyo we-charcoal ekrwada (i-petroleum coke, i-asphalt coke njenge-coke ye-coke, njl.
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 esiguqulwe ngamasuntswana ekhabhoni njengepetroleum coke okanye i-asphalt coke, isigaba segraphite esiguqulwa ngamalahle e-pitch binder agqunywe ngamasuntswana, ukuqokelelwa kwamasuntswana okanye iipores ezenziwe yi-binder yamalahle emva konyango lobushushu, njl njl. Imveliso yemizi-mveliso yegraphite eyenziweyo, iqondo legraphitization lidla ngokuba ngaphantsi 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 ibandakanya petroleum coke, inaliti coke, asphalt coke, pitch amalahle, carbon microspheres, njl. Iimveliso zayo ezisezantsi ikakhulu ziquka electrode graphite, anode pre-baked, graphite isostatic, graphite ukucoceka eliphezulu, igraphite yenyukliya, umtshintshiselwano ubushushu njalo njalo.
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. Igraphite ekhethekileyo: kunye nomgangatho ophezulu wepetroleum coke njengento ekrwada, i-pitch yamalahle okanye i-resin yokwenziwa njenge-binder, ngokulungiselela izinto ezikrwada, ukuxubha, ukuxova, ukucinezela, ukutyumza, ukuxuba ukuxova, ukubumba, ukugcoba okuninzi, ukungena kaninzi, ukuhlanjululwa kunye ne-graphitization, i-machining kunye neyenziwe, ngokubanzi, kubandakanya i-isoerograph ephezulu ye-isoerograph, i-nuclear graphite eletroniki, amacandelo oshishino lwenyukliya.
