Igrafu ehlanzekile ephezuluKubhekiswa kugrafu ngokuqukethwe kwekhabhoni kukhulu kune-99.99%. I-graphite ephezulu yokumsulwa inezinzuzo ezinjengokumelana okuphezulu kwamazinga okushisa, ukumelana nokugqwala, ukumelana okushisayo, ukukhohlisa okuphansi okukhohlisayo, ukukhohlisa okuphansi, ukuvumelanisa okuphansi kwe-mechanic. Ukwenza ucwaningo ngenqubo yokukhiqiza ye-graphite ephezulu yokuhlanzeka kanye nokwenza ngcono ikhwalithi yomkhiqizo kubaluleke kakhulu ekuthuthukisweni komkhakha we-graphitity ahlanzekile eChina.
Ukuze kuthuthukiswe ukuthuthukiswa komkhakha we-graphite we-China ophakeme, inkampani yethu itshale imali enkulu yabasebenzi kanye nezinsizakusebenza ocwaningweni nasekuthuthukisweni kwegrafu ethuthukisiwe yokuhlanza okuphezulu, okwenza iminikelo ebalulekile ekwenzeni indawo yokuhlanza okuphezulu. Manje ake ngikutshele ngocwaningo lwenkampani yethu yokucwaninga kanye nempumelelo:
- Ukugeleza kwenqubo okujwayelekile kokukhiqiza i-graphity ehlanzekile ephezulu:
Inqubo enkulu yokukhiqiza ye-graphite yokuhlanza okuphezulu ikhonjiswa kuMdwebo 1. Kuyacaca ukuthi inqubo yokukhiqiza ye-graphite yokuhlanza okuphezulu ihlukile kwaleyo ye-graphite electrodes. I-graphite ephezulu yokuhlanzeka idinga izinto ezihlekisayo ze-isotropic, ezidinga ukuba zibe yimikhawulo ibe ngamapopi amahle. Ubuchwepheshe bokubumba bokucindezela okuzayo budinga ukusetshenziswa, futhi umjikelezo othosiwe isikhathi eside. Ukuze kufinyelelwe ubungako obufunayo, kudingeka imijikelezo eminingi yokuthosela okuthosiwe, futhi umjikelezo wokuqhafaza musa kakhulu kune-graphite ejwayelekile.
1.1 Izinto ezingavuthiwe
Izinto ezivuthiwe zokukhiqiza i-graphite ephezulu yokuhlanza zifaka phakathi ama-agregates, ama-linders, kanye nama-ejenti okufaka. Ama-aggregates ajwayele ukwenziwa nge-Petroleum Coke ye-Wistele Lokhu kungenxa yokuthi i-Petroleum Coke ephethe i-Petroleum anezimpawu ezinjengokuqukethwe okuphansi kwe-Ash (ngokuvamile ngaphansi kwe-1%), ukuthuthuka okulula ekushintshiseni okuphezulu, ukuvumelanisa okushisayo, kanye nokwenziwa okuhle kakhulu; I-graphite etholwe ngokusebenzisa i-asphalt Coke endaweni yokushisa efanayo ye-grashtization inokumelana kagesi okuphezulu kepha amandla aphezulu emishini. Ngakho-ke, lapho ukhiqiza imikhiqizo egqamile, ngaphezu kwe-petroleum coke, ingxenye ye-asphalt Coke nayo isetshenziselwa ukuthuthukisa amandla omshini womkhiqizo. Ama-Binders ajwayele ukusebenzisa i-Coal Tar Pitch,okuwumkhiqizo wenqubo ye-distillation yocingo lwamalahle. Kuyinto eqinile emnyama emazingeni okushisa asekamelweni futhi ayinawo indawo yokuncibilika ehleliwe.
1.2 I-CALLINAGE / Ukuhlanjululwa
I-calcaination ibhekisela ekwelashweni okushisa okushisa kakhulu kwezinto ezahlukahlukene eziqinile zekhabhoni ngaphansi kwezimo zomoya eziqhekekile. Ama-agregates akhethiwe aqukethe ama-degree ahlukahlukene omswakama, ukungcola, noma izinto ezishintshashintshayo esakhiweni sangaphakathi ngenxa yokwahlulela ekuvumeni kwamazinga okushisa kwamalahle. Lezi zinto zidinga ukususwa kusengaphambili, uma kungenjalo kuzothinta ikhwalithi yomkhiqizo nokusebenza. Ngakho-ke, ama-aggregate akhethiwe kufanele athwelwe noma ahlanziwe.
1.3 Ukugaya
Izinto eziqinile ezisetshenziselwa ukukhiqizwa kwe-graphite, yize usayizi we-block uncishiswa ngemuva kwe-carvunation noma ukuhlinza, usenesayizi enkulu yezinhlayiyana ngokuguquguquka okukhulu nokuqanjwa okungalingani. Ngakho-ke, kuyadingeka ukuchoboza usayizi we-Aggregate Particle ukuze ahlangabezane nezidingo zesithako.
1.4 ukuxuba nokuxova
I-powder yomhlabathi idinga ukuxutshwa nge-coal tar binder ngesilinganiso ngaphambi kokufakwa umshini wokududuza ovuthayo ukuze uqiniseke ukuqinisekisa ukusatshalaliswa okufanayo kwezinto ezibonakalayo.
1.5 kwakha
Izindlela eziphambili zifaka ukubumba kokukhishwa, ukubumba, ukubumba okudlidliza, nokubumba okuzayo okuzayo
1.6 Baking
Imikhiqizo ye-carbon eyakhekile kumele ibhekane nenqubo egazingiwe, efaka phakathi i-carbonising the bheji ku-binder coke ngokusebenzisa ukwelashwa okushisa (cishe ama-1000 ℃) ngaphansi kwezimo zomoya ezihlukile.
1.7 Ukuthunyelwa
Inhloso yokuwohloka ukugcwalisa ama-pores amancane akhiwa ngaphakathi komkhiqizo ngesikhathi senqubo egcwele ama-ascle, ukuthuthukisa amandla aphezulu okuvulwa, ukuthuthukisa amakhemikhali, amandla okuqina kwamakhemikhali womkhiqizo.
1.8 i-graphitization
I-graphialization ibhekisa kwinqubo yokushisa okushisa okushisa okuguqula i-thermodynamicale ingapheli ikhabhoni ikhabhoni ku-graphite carbon ngokusebenzisa kusebenze okushisayo.
Uyemukelwa ukuvakashela futhi uhlole ifektri yethu, uhlanganyele kakhulu ku-graphite isikhunta, i-graphines ephezulu yokuhlanza, i-graphite powder, ama-graphite acindezela ama-graphite, njalonjalo.
