Coke irbadu waa noocyo kala duwan oo tayo sare leh oo si xoog leh loogu sameeyay alaabta kaarboonka.Muuqaalkiisu waa mid adag oo daloola oo leh cawl qalin ah iyo dhalaal macdan ah.Qaab dhismeedkeedu waxa uu leeyahay muuqaal qulqulaya oo muuqda, oo leh godad waaweyn laakiin yar iyo qaab oval ah.Waa alaabta ceeriin ee lagu soo saaro alaabada kaarboon-dhamaadka sare leh sida korantada ultra-sare leh, walxo kaarboon gaar ah, fiber carbon iyo walxo isku dhafan.
Sida laga soo xigtay alaabta ceeriin ee kala duwan, kookaha irbadda waxaa loo qaybin karaa coke cirbadda saliidda iyo kookaha irbadda dhuxusha.Coke irbadda laga soo saaro hadhaaga batroolka waa kookaha irbadda saliidda.Kookaha irbadda ee laga soo saaro garoonka daamurka dhuxusha iyo jajabkeedu waa kookaha irbadda taxanaha ah ee dhuxusha.
Tilmaamaha saameeya tayada kookaha irbadda waxaa ka mid ah cufnaanta dhabta ah, maadada baaruudda, maadada nitrogen, maadada kacsan, content ash, coefficient ballaadhinta kulaylka, caabbinta, cufnaanta gariirka, iwm. heer sare ah (fasalka ugu fiican), fasalka koowaad iyo fasalka labaad.
Farqiga waxqabadka ee u dhexeeya dhuxusha iyo coke cirbadda saliidda waxaa ka mid ah qodobbada soo socda.
1. Isla shuruudo la mid ah, kookaha graphite ee ka samaysan coke cirbadda saliidda ayaa ka fudud in la qaabeeyo marka loo eego coke cirbadda dhuxusha.
2. Ka dib marka la sameeyo alaabta graphite, cufnaanta iyo xoogga alaabta graphitized ee saliidda coke cirbadaha ayaa wax yar ka sarreeya kan kookaha irbadda dhuxusha, taas oo ay sababtay balaadhinta irbadda kookaha ee taxanaha dhuxusha inta lagu jiro graphitization.
3. Isticmaalka gaarka ah ee graphite electrode, badeecada graphitized ee coke cirbadda saliidda waxay leedahay isugeyn hoose oo balaadhinta kulaylka.
4. Marka la eego tusmooyinka jireed iyo kiimikaad ee graphite electrode, iska caabbinta gaarka ah ee badeecada graphitized ee coke cirbadda saliidda ayaa waxyar ka sareysa tan alaabta coke irbadda.
5. Tan ugu muhiimsan waa in dhuxusha cabbirka coke cirbadaha balaadhiso marka heerkulku gaadho 1500-2000 ℃ habka garaafaynta heerkulka sare, markaa heerka kor u kaca heerkulka waa in si adag loo xakameeyo, ma aha kor u kaca heerkulka degdega ah, waxaa fiican inaadan isticmaalin wax soo saarka garaafyada taxane ah, dhuxusha cabbirka cirbadda coke adoo ku daraya wax lagu daro si loo xakameeyo fidinta, heerka ballaarinta waa la dhimi karaa.Laakiin way adag tahay in la gaaro kookaha cirbadda saliidda.
6. Coke irbadda saliidda calcined ayaa ka badan kookaha yar yar iyo size qayb ganaax, halka coke irbadda dhuxusha uu leeyahay content ka yar iyo size qayb weyn (35 — 40 mm), kaas oo buuxin kara shuruudaha size qayb caanaha, laakiin waxa ay keentaa dhibaatooyin dadka isticmaala.
7. Sida laga soo xigtay hordhaca Japan Petroleum Coke Company, waxaa la rumeysan yahay in ka kooban coke irbadda saliidda waa ka sahlan yahay coke irbadda dhuxusha, sidaas darteed ay fududahay in la xakameeyo coking iyo wakhtiga kululaynta.
Laga soo bilaabo kor ku xusan, coke cirbadda saliiddu waxay leedahay afar hoose: cuf-jiid gaar ah oo been abuur ah, xoog hooseeya, CTE hoose, iska caabin gaar ah oo hooseeya, labada ugu horreeya ee hooseeya ee alaabta graphite, labada ugu dambeeya ee hooseeya ee alaabta graphite waa mid wanaagsan.Guud ahaan, tusmooyinka waxqabadka ee coke cirbadaha taxanaha saliidda ayaa ka wanaagsan coke coke taxane ah oo dhuxul ah, iyo dalabka codsigu sidoo kale waa ka sii badan yahay.
Waqtigan xaadirka ah, graphite electrode waa suuqa ugu weyn ee baahida coke irbadda, oo lagu xisaabtamayo 60% wadarta codsiga coke irbadda, halka shirkadaha korantada ay leeyihiin baahi cad oo tayo leh oo loogu talagalay coke cirbadda, iyada oo aan la helin baahi tayo gaar ah.Baahida coke cirbadda ee lithium ion batteriga anode waa mid aad u kala duwan, suuqa dhijitaalka ah ee-dhamaadka sare wuxuu jecel yahay saliidda la kariyey ee la kariyey, suuqa batteriga korantadu wuxuu aad ugu tiirsan yahay kookaha oo leh qiimo sare leh.
Soo saarista coke cirbadaha waxay leedahay heer farsamo oo gaar ah, sidaa darteed ganacsiga gudaha waa naadir.Waqtigan xaadirka ah, shirkadaha wax soo saarka guud ee gudaha ee coke irbadda saliidda waxaa ka mid ah: Weifang Fumei tamarta cusub, Shandong Jingyang, Shandong Yida, Jinzhou Petrochemical, Shandong Lianhua, Bora Biological, Weifang Fumei tamarta cusub, Shandong Yiwei, Sinopec jinling Petrochemical, Maoming petrochemical, iwm Taxanaha dhuxusha coke shirkadaha wax soo saarka caadiga ah Baowu carbon, technology Baotailong, Anshan kaarboon furan, Anshan Chemical, Fang Daxi ke Mo, Shanxi Macro, Henan furan carbon, Xuyang Group, Zaozhuang noolaynta, Ningxia Baichuan, Tangshan Dongri tamarta cusub, Taiyuan Shengxu iyo wixi la mida.
