Coke irbadu waa noocyo kala duwan oo tayo sare leh oo si xoog leh loogu soo saaray walxaha kaarboonka. Muuqaalkiisu waa mid adag oo daloola oo leh cawl qalin ah iyo dhalaal macdan ah. Qaab dhismeedkeedu waxa uu leeyahay qaab socodka muuqda, oo leh daloolo waaweyn laakiin yar iyo qaab oval ah. Waa alaabta ceeriin ee lagu soo saaro alaabada kaarboon-dhamaadka sare leh sida korantada korantada aadka u saraysa, qalabka kaarboonka ee gaarka ah, fiber carbon iyo agabkeeda isku dhafan.
Marka loo eego qalabka wax soo saarka ee kala duwan, coke cirbadda waxaa loo qaybin karaa taxane saliid ah iyo taxane dhuxul laba nooc oo coke irbad ah. Coke irbadda oo lagu soo saaray hadhaaga batroolka sida alaabta ceeriin waa kookaha irbadda taxanaha ah ee saliidda. Coke-ga cirbadda dhuxusha ee laga soo saaro garoonka daamurka dhuxusha iyo jajabkeeda waxaa loo yaqaannaa coke cirbadda cabbirka dhuxusha.
Tilmaamaha saameeya tayada kookaha irbadda waxaa ka mid ah cufnaanta dhabta ah, maadada baaruudda, content nitrogen, content volatile, content ash, coefficient fidinta kulaylka, caabbinta korantada, cufnaanta gariirka, iwm. loo qaybiyo fasalka super (fasalka sare), fasalka koowaad iyo fasalka labaad.
Farqiga waxqabadka ee u dhexeeya qiyaasta dhuxusha coke cirbadda iyo cabbirka saliidda coke cirbadda waxaa ka mid ah qodobada soo socda.
1. Isla shuruudo isku mid ah, electrode graphite oo ka samaysan saliid taxane ah coke waa sahlan tahay in la sameeyo marka loo eego coke cirbadaha dhuxusha marka loo eego waxqabadka.
2. Ka dib markii alaabta graphite la sameeyo, alaabta graphitized ee taxanaha saliid coke leeyihiin cufnaanta wax yar ka sarreeya iyo xoog ka mid ah kookaha irbado taxane dhuxul, taas oo ay sababtay balaadhinta ee taxanaha dhuxusha coke inta lagu guda jiro graphitization.
3. Isticmaalka gaarka ah ee graphite electrode, alaabta garaafyada leh ee kookaha cirbadda saliiddu waxay leeyihiin isugeyn hoose oo balaadhinta kulaylka.
4. Marka la eego tusmooyinka jireed iyo kiimikaad ee electrode graphite, iska caabin gaar ah ee alaabta graphitized ee saliid taxane coke irbadu wax yar ka sarreeyaa alaabta coke irbad taxane dhuxul ah.
5. Waxa ugu muhiimsan waa in kookaha cirbadda dhuxusha ay ku balaadhiso habka garaafka heerkulku sareeyo, marka heerkulku gaadho 1500-2000 ℃, markaa xawliga kor u kaca heerkulka waa in si adag loo xakameeyo, ma aha in si degdeg ah loo kululeeyo, waxaa fiican in aan isticmaal habka garaafaynta taxane ah, cabbir dhuxusha coke irbadda adoo ku daraya wax lagu daro si loo xakameeyo fidinta, heerka balaadhinta waa la dhimi karaa. Laakiin way adag tahay in la gaaro saliidda - coke cirbadda ku salaysan.
6. Nadaamka saliidda calcined waxa uu ka kooban yahay kookaha yar yar iyo xajmi yar, halka irbadda dhuxusha ay leedahay maadada kookaha ka yar iyo cabbirka badarka weyn (35-40 mm), kaas oo buuxin kara shuruudaha cabbirka hadhuudhka ee caanaha, laakiin waxay keenaysaa dhibaato. si ay u burburiyaan isticmaalaha.
7. Sida laga soo xigtay Shirkadda Shidaalka ee Japan Petroleum Coke, waxaa loo arkaa in isku-dhafka saliidda taxanaha ah ee kookaha uu ka fudud yahay midka dhuxusha ee kookaha, markaa way fududahay in la xakameeyo inta lagu jiro habka kookeynta.
Marka laga eego aragtida kor ku xusan, kookaha cirbadda nidaamka saliidda ayaa leh afar hoose: cuf-jiid gaar ah oo hooseeya, 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 fiican kuwa dhuxusha taxanaha ah ee coke, iyo dalabka dalabka ayaa ka badan.
Waqtigan xaadirka ah, graphite electrode waa suuqa ugu weyn ee baahida coke irbadda, oo lagu xisaabtamayo 60% wadarta codsiga coke irbadda, iyo shirkadaha korantada waxay leeyihiin baahi cad oo loogu talagalay tayada coke irbadda, iyada oo aan lahayn baahi tayo leh oo shaqsiyeed. Qalabka anode-ka ee baytariga Lithium ion waxay leeyihiin baahiyo kala duwan oo loogu talagalay coke cirbadda, suuqa dhijitaalka ah ee dhamaadka-sare wuxuu doorbidaa kookaha saliidda la kariyey, suuqa baytariga korantada wuxuu aad ugu tiirsan yahay kookaha cayriin ee waxtarka badan leh.
Wax soo saarka coke cirbaddu waxay leedahay heer farsamo oo gaar ah, sidaas darteed waxaa jira dhowr shirkadood oo gudaha ah. Waqtigan xaadirka ah, warshadeeyayaasha coke ee taxanaha saliida gudaha waxaa ka mid ah Shandong Jingyang, Shandong Yida, Jinzhou Petrochemical, Shandong Lianhua, Bora Biological, Weifang Fumei New Energy, Shandong Yiwei, Sinopec Jinling Petrochemical, Maoming Petrochemical, iwm. Soosaarayaasha ugu muhiimsan ee cabbirka dhuxusha coke irbadda waa Baowu Carbon Material, Baotailong Technology, Anshan Kaitan, Angang Chemical, Fang Daxi Kemo, Shanxi Hongte, Henan Kaitan, Xuyang Group, Zaozhuang Zhenxing, Ningxia Baichuan, Tangshan Dongri New Energy, Taiyuan Shengxu, iwm.
