Koob coke yog cov khoom siv zoo heev uas tsim los ntawm cov ntaub ntawv carbon. Nws cov tsos yog cov khoom ntxeem tau nrog nyiaj grey thiab xim hlau luster. Nws cov qauv muaj kev ntxhib los mos zoo nkauj, nrog loj tab sis ob peb qhov thiab me ntsis oval duab. Nws yog cov khoom siv raw rau kev tsim cov khoom siv high-end carbon xws li ultra-siab zog electrode, cov khoom siv tshwj xeeb carbon, carbon fiber thiab nws cov ntaub ntawv sib xyaw.
Raws li cov khoom siv sib txawv, cov koob coke tuaj yeem muab faib ua cov roj series thiab thee series ob hom koob coke. Cov koob coke ua nrog roj av residue li raw khoom yog roj series koob coke. Cov thee ntsuas koob coke ua los ntawm cov thee tar pitch thiab nws cov feem yog hu ua thee ntsuas koob coke.
Cov indexes uas cuam tshuam rau qhov zoo ntawm koob coke muaj xws li qhov tseeb ntom ntom, cov ntsiab lus sulfur, cov ntsiab lus nitrogen, cov ntsiab lus tsis hloov pauv, cov ntsiab lus tshauv, thermal expansion coefficient, hluav taws xob tiv thaiv, kev co-khoom ntom ntom, thiab lwm yam. Vim muaj qhov sib txawv tshwj xeeb index coefficients, koob coke tuaj yeem muab faib ua qib super (qib superior), qib thawj thiab qib thib ob.
Qhov kev ua tau zoo sib txawv ntawm cov thee ntsuas koob coke thiab roj ntsuas koob coke suav nrog cov ntsiab lus hauv qab no.
1. Nyob rau tib lub sijhawm, cov graphite electrode ua los ntawm cov roj series koob coke yog yooj yim dua los tsim dua cov thee series koob coke nyob rau hauv cov nqe lus ntawm kev ua tau zoo.
2. Tom qab cov khoom lag luam graphite tau tsim, cov khoom lag luam graphitized ntawm cov roj series koob coke muaj qhov ntom ntom me ntsis thiab lub zog ntau dua li cov thee series koob coke, uas yog tshwm sim los ntawm kev nthuav dav ntawm cov thee series koob coke thaum graphitization.
3. Hauv kev siv tshwj xeeb ntawm graphite electrode, cov khoom siv graphitized nrog roj koob coke muaj qis coefficient ntawm thermal expansion.
4. Nyob rau hauv cov nqe lus ntawm lub cev thiab tshuaj indexes ntawm graphite electrode, qhov tshwj xeeb kuj ntawm graphitized cov khoom ntawm cov roj series koob coke yog me ntsis siab dua li cov thee series koob coke khoom.
5. Qhov tseem ceeb tshaj plaws yog qhov ntsuas kub ntawm rab koob coke nthuav dav hauv cov txheej txheem ntawm kev kub siab graphitization, thaum kub nce mus txog 1500-2000 ℃, yog li qhov kub nce ceev yuav tsum tau tswj nruj me ntsis, tsis kub ceev, nws yog qhov zoo tshaj plaws kom tsis txhob kub hnyiab. siv series graphitization txheej txheem ntau lawm, thee ntsuas koob coke los ntawm kev ntxiv additives los tswj nws expansion, expansion tus nqi yuav txo tau. Tab sis nws yog qhov nyuaj dua kom ua tiav cov roj - raws li koob coke.
6. Lub kaw lus roj calcined muaj cov ntsiab lus me me ntawm coke ntau dua thiab cov nplej zoo dua, thaum lub koob ntsuas lub thee muaj cov ntsiab lus coke tsawg dua thiab cov nplej loj dua (35-40 mm), uas tuaj yeem ua tau raws li qhov xav tau ntawm cov qauv ntawm cov qauv, tab sis ua rau muaj teeb meem. rau tus neeg siv crushing.
7. Raws li Nyiv Petroleum Coke Company, nws tau txiav txim siab tias muaj pes tsawg leeg ntawm cov roj series koob coke yog yooj yim dua li cov thee series koob coke, yog li nws yooj yim los tswj thaum lub sijhawm coking.
Los ntawm cov ntsiab lus saum toj no, cov roj system koob coke muaj plaub qhov qis: qis tshwj xeeb lub ntiajteb txawj nqus, tsis tshua muaj zog, tsis tshua muaj CTE, tsis tshua muaj kev tiv thaiv, thawj ob qhov qis ntawm cov khoom siv graphite, ob qhov kawg ntawm cov khoom siv graphite yog qhov zoo. Feem ntau hais lus, qhov Performance indexes ntawm roj series koob coke yog zoo dua li cov thee series koob coke, thiab daim ntawv thov xav tau ntau dua.
Tam sim no, graphite electrode yog lub lag luam tseem ceeb ntawm koob coke, suav txog li 60% ntawm tag nrho daim ntawv thov ntawm koob coke, thiab cov tuam txhab electrode muaj qhov xav tau meej rau koob coke zoo, tsis muaj tus kheej xav tau. Lithium ion roj teeb anode cov ntaub ntawv muaj ntau haiv neeg thov rau koob coke, high-end digital lag luam nyiam roj siav coke, lub hwj chim roj teeb lag luam yog nyob ntawm ntau tus nqi-zoo raw coke.
Kev tsim cov koob coke muaj qee qhov kev ua haujlwm, yog li muaj qee qhov kev lag luam hauv tsev. Tam sim no, lub hauv paus tseem ceeb roj series koob coke manufacturers suav nrog Shandong Jingyang, Shandong Yida, Jinzhou Petrochemical, Shandong Lianhua, Bora Biological, Weifang Fumei Tshiab Zog, Shandong Yiwei, Sinopec Jinling Petrochemical, Maoming Petrochemical, thiab lwm yam. koob coke yog Baowu Carbon Materials, Baotailong Technology, Anshan Kaitan, Angang Chemical, Fang Daxi Kemo, Shanxi Hongte, Henan Kaitan, Xuyang Group, Zaozhuang Zhenxing, Ningxia Baichuan, Tangshan Dongri Tshiab Zog, Taiyuan Shengxu, thiab lwm yam.
