High ubumsulwa graphiteisho i-graphite enokuqukethwe kwekhabhoni engaphezu kuka-99.99%.I-graphite yokuhlanzeka okuphezulu inezinzuzo ezifana nokumelana nokushisa okuphezulu, ukumelana nokugqwala, ukumelana nokushaqeka okushisayo, i-coefficient ephansi yokwandisa ukushisa okushisayo, ukuzigcoba ngokwakho, i-coefficient ephansi yokumelana, kanye nokucubungula okulula komshini.Ukwenza ucwaningo ngenqubo yokukhiqiza i-graphite emsulwa kanye nokwenza ngcono ikhwalithi yomkhiqizo kubaluleke kakhulu ekuthuthukisweni kwemboni ye-graphite yaseShayina ehlanzekile.
Ukuze kuthuthukiswe ukuthuthukiswa kwemboni ye-graphite yaseShayina ehlanzekile, inkampani yethu itshale isamba esikhulu sabasebenzi kanye nezinsiza ocwaningweni nasekuthuthukisweni kwegraphite esezingeni eliphakeme, yenza igalelo elibalulekile ekusetshenzisweni kwasendaweni kwe-high-purity graphite.Manje ake ngikutshele ngocwaningo nentuthuko yenkampani yethu:
- Ukugeleza kwenqubo evamile yokukhiqiza i-high-purity graphite:
Inqubo yokukhiqiza eyinhloko ye-graphite ephezulu yokuhlanzeka iboniswa kuMfanekiso 1. Kusobala ukuthi inqubo yokukhiqiza i-graphite ehlanzekile kakhulu ihluke kuleyo ye-graphite electrode.I-graphite ehlanzekile idinga izinto ezingavuthiwe ze-isotropic, ezidinga ukugaywa zibe izimpushana ezicolekile.Ubuchwepheshe bokubumba obucindezela be-Isostatic budinga ukusetshenziswa, futhi umjikelezo wokugazinga mude.Ukuze kuzuzwe ukuminyana okufunayo, imijikelezo yokuthosa eningi iyadingeka, futhi umjikelezo we-graphitization mude kakhulu kunegraphite evamile.
1.1 Izinto ezisetshenziswayo
Izinto zokusetshenziswa zokukhiqiza i-high-purity graphite zifaka ama-aggregates, ama-binders, nama-ejenti okukhulelwa.Ama-aggregates ngokuvamile enziwa nge-petroleum coke efana nenaliti kanye ne-asphalt coke.Lokhu kungenxa yokuthi i-petroleum coke efana nenaliti inezici ezifana nokuqukethwe komlotha ophansi (ngokuvamile okungaphansi kuka-1%), i-graphitization elula emazingeni okushisa aphezulu, ukuqhutshwa kahle kwe-thermal conductivity, kanye ne-coefficient ephansi yomugqa wokwandisa;I-graphite etholwe ngokusebenzisa i-asphalt coke ekushiseni okufanayo kwe-graphitization ine-resistivity kagesi ephakeme kodwa amandla aphezulu emishini.Ngakho-ke, lapho ukhiqiza imikhiqizo ye-graphitized, ngaphezu kwe-petroleum coke, ingxenye ye-asphalt coke isetshenziselwa ukuthuthukisa amandla omshini womkhiqizo.Izibophezelo ngokuvamile zisebenzisa itiyela yamalahle,okuwumkhiqizo wenqubo yokucwiliswa kwetiyela lamalahle.Iqinile elimnyama ezingeni lokushisa elilingana negumbi futhi ayinakho ukuncibilika okugxilile.
1.2 Ukubalwa/Ukuhlanzwa
Ukubalwa kubhekisela ekwelashweni okushisisa okuphezulu kwezinga eliphezulu kwekhabhoni eluhlaza okuqinile ngaphansi kwezimo zomoya ezingazodwa.Izilinganiso ezikhethiwe ziqukethe amazinga ahlukahlukene omswakamo, ukungcola, noma izinto eziguquguqukayo esakhiweni sazo sangaphakathi ngenxa yomehluko wamazinga okushisa okubhaka noma iminyaka yokuma kwezwe yokwakheka kwamalahle.Lezi zinto zidinga ukuqedwa kusengaphambili, ngaphandle kwalokho kuzothinta izinga lomkhiqizo nokusebenza.Ngakho-ke, ama-aggregates akhethiwe kufanele abalwe noma ahlanzwe.
1.3 Ukugaya
Izinto eziqinile ezisetshenziselwa ukukhiqizwa kwe-graphite, nakuba usayizi webhulokhi uncishisiwe ngemva kokubala noma ukuhlanzwa, usenosayizi omkhulu wezinhlayiyana ngokuguquguquka okuphawulekayo nokwakheka okungalingani.Ngakho-ke, kuyadingeka ukuchoboza usayizi wezinhlayiyana ezihlanganisiwe ukuze uhlangabezane nezidingo zesithako.
1.4 Ukuxuba nokuxova
Impushana yomhlabathi idinga ukuxutshwa ne-binder yetiyela yamalahle ngokulingana ngaphambi kokuba ifakwe emshinini wokuxova oshisayo ukuze uxove ukuze kuqinisekiswe ukusatshalaliswa okufanayo kwempahla.
1.5 Ukwakha
Izindlela eziyinhloko zifaka ukubunjwa kwe-extrusion, ukubumba, ukubumba kokudlidliza, kanye nokubunjwa kokucindezela kwe-isostatic
1.6 Ukubhaka
Imikhiqizo yekhabhoni eyakhiwe kumele ingene kwinqubo yokugazinga, okubandakanya ukufaka i-carbonizing i-binder ibe yi-binder coke ngokwelashwa kokushisa (okungaba ngu-1000 ℃) ngaphansi kwezimo zomoya ezingazodwa.
1.7 Ukukhulelwa
Inhloso yokufakelwa ukugcwalisa ama-pores amancane akhiwe ngaphakathi komkhiqizo ngesikhathi sokugaya nge-asphalt encibilikisiwe nezinye izinto ezifaka ukukhulelwa, kanye nama-pores akhona avulekile ezinhlayiyeni ze-coke ezihlanganisiwe, ukuthuthukisa ukuminyana kwevolumu, ukuqhutshwa, amandla omshini, kanye nokumelana nokugqwala kwamakhemikhali komkhiqizo.
1.8 I-Graphitization
I-Graphitization ibhekisela kunqubo yokwelapha ukushisa okusezingeni eliphezulu okushintsha i-thermodynamically engazinzile i-non graphite carbon ibe yi-graphite carbon ngokwenza kusebenze okushisayo.
Siyakwamukela ukuthi uvakashele futhi uhlole imboni yethu, esebenza kakhulu ekubunjweni kwe-graphite, i-graphite ephezulu, i-graphite crucibles, i-nano graphite powder, i-isostatic pressing graphite, i-graphite electrode, i-graphite rods, njalonjalo.
