• Cov roj av Coke uas muaj graphitized: Tom qab kho graphitization ntawm qhov kub siab txog li 3000 ° C, cov pa roj carbon atoms raug hloov pauv mus rau hauv cov qauv graphite hexagonal. Cov qauv no muaj cov qauv lattice siab, cov zog interlayer tsis muaj zog, thiab kev tiv thaiv electron migration qis. Qhov kev hloov pauv qauv no muab nws nrog cov khoom graphite ib txwm muaj, xws li kev ua hluav taws xob siab, kev ua thermal siab, thiab kev ruaj khov tshuaj zoo heev.

2. Kev Sib Txawv ntawm Kev Ua Haujlwm: Cov Qauv Txiav Txim Siab Txog Kev Ua Haujlwm

Kev Ua Hluav Taws Xob thiab Kev Ua Kub

• Cov roj av graphitized: Nws qhov resistivity qis dua li cov roj av coke ib txwm muaj (tuaj yeem qis dua 0.001 Ω·m), thiab nws cov thermal conductivity ntau zaus dua. Nws yog qhov tsim nyog rau cov xwm txheej nrog cov kev cai nruj ntawm hluav taws xob thiab thermal conductivity (piv txwv li, cov ntaub ntawv anode rau cov roj teeb lithium-ion, cov hluav taws xob graphite muaj zog heev).
• Cov Roj Coke Ib Txwm Muaj: Vim yog qhov tsis zoo ntawm cov qauv, nws muaj kev coj hluav taws xob tsis zoo thiab feem ntau yog siv rau hauv cov teb uas muaj qhov yuav tsum tau ua haujlwm tsawg (piv txwv li, roj, cov ntaub ntawv carbon ib txwm muaj).

Kev Ruaj Ntseg Tshuaj

• Graphitized Petroleum Coke: Nws cov qauv txheej txheem ua rau nws tiv taus cov tshuaj xeb los ntawm cov kua qaub, alkalis, thiab lwm yam. Nws tsis yooj yim rau oxidation thiab lwj thaum kub siab, ua rau lub neej ua haujlwm ntev dua.
• Cov Roj Coke Ib Txwm Muaj: Nws yooj yim raug puas tsuaj rau cov qauv hauv qhov kub siab lossis qhov chaw corrosive, ua rau kev ua haujlwm poob qis sai.

Cov Ntsiab Lus Tsis Huv

• Graphitized Petroleum Coke: Cov txheej txheem graphitization tuaj yeem txo cov ntsiab lus ntawm cov khoom tsis huv xws li sulfur thiab nitrogen (cov ntsiab lus sulfur tuaj yeem txo qis dua 0.1%), txo qis kev ua qias tuaj thiab cov teebmeem tsis zoo thaum lub sijhawm smelting (piv txwv li, qhov hws thiab cov kab nrib pleb hauv cov castings).
• Cov Roj Av Coke Ib Txwm Muaj: Nws muaj cov ntsiab lus tsis huv siab thiab xav tau kev kho ua ntej (piv txwv li, calcination) kom tau raws li qhov xav tau ntawm qee qhov kev siv hauv kev lag luam.

3. Cov Kev Siv: Kev Sib Txawv ntawm Kev Ua Haujlwm Tsav Kev Sib Txawv ntawm Kev Xav Tau

Cov roj av graphitized Coke

• Kev Siv Hlau Zoo Tshaj Plaws: Ua ib lub carburizer, nws tuaj yeem ua kom cov pa roj carbon ntawm cov hlau molten zoo dua thiab txhim kho cov khoom ntawm cov hlau (piv txwv li, lub zog, kev tawv), thaum txo cov khoom phom sij xws li sulfur thiab nitrogen.
• Cov Khoom Siv Hluav Taws Xob Tshiab: Nws yog cov khoom siv tseem ceeb rau cov khoom siv anode ntawm cov roj teeb lithium-ion. Nws cov hluav taws xob conductivity siab thiab cov qauv txheej pab txhim kho qhov them-tawm efficiency thiab lub voj voog lub neej ntawm cov roj teeb.
• Cov Khoom Siv Carbon Tshwj Xeeb: Siv rau hauv kev tsim cov cathode blocks loj, graphitized electrodes, thiab lwm yam, vam khom nws qhov kev ntshiab siab, crystallinity siab, thiab kev tiv taus kub siab.

Cov roj av Coke ib txwm muaj

• Roj Av: Cov coke uas muaj sulfur ntau feem ntau siv rau hauv cov chaw tsim cement, cov chaw tsim iav, cov chaw tsim hluav taws xob, thiab lwm yam, ua roj pheej yig.
• Cov Khoom Siv Carbon Yooj Yim: Cov coke uas muaj sulfur tsawg, tom qab calcination, tuaj yeem siv rau hauv kev tsim cov anodes rau aluminium electrolysis, cov electrodes graphite ib txwm muaj, thiab lwm yam, tab sis nws cov kev ua tau zoo qis dua li cov khoom graphitized.

4. Cov Txheej Txheem Tsim Khoom: Kev Sib Pauv Ntawm Qhov Kub thiab Tus Nqi

• Cov Coke Roj Av Ib Txwm: Tsim los ntawm kev siv cov txheej txheem coking qeeb lossis cov txheej txheem coking kua, nrog rau tus nqi qis dua. Txawm li cas los xij, nws yuav tsum tau calcination ntxiv (kwv yees li 1300 ° C) kom tshem tawm cov khoom tsis haum thiab cov dej noo, yog li ua rau cov pa roj carbon ruaj khov ntau ntxiv.
• Cov Roj Av Coke Uas Muaj Graphitized: Siv cov roj av coke ib txwm ua cov khoom siv raw, nws xav tau kev kho graphitization kub ntxiv ntawm kwv yees li 3000 ° C. Qhov no ua rau kev siv hluav taws xob thiab cov nqi khoom siv nce ntxiv, tab sis cov khoom muaj nqis ntxiv ntau dua.
