Thaum siv cov roj av coke uas muaj graphitized, kom tsis txhob muaj "kev tsis zoo" nrog lwm yam khoom hauv lub cub tawg, yuav tsum tau ua kom tiav los ntawm cov yam xws li tswj tus nqi cua sov, ua kom zoo dua qhov kub thiab txias, xyuas kom muaj cua sov sib npaug, xaiv cov khoom siv tiv taus kom haum, tswj cov ntsiab lus tsis huv, siv qhov txias tsim nyog, thiab txhawb nqa kev saib xyuas cov khoom siv. Cov ntsiab lus yog raws li nram no:
Kev Tswj Tus Nqi Kub: Thaum lub sijhawm ua kom sov ntawm cov roj av coke graphitized, nws yog ib qho tseem ceeb kom tswj tus nqi kub kom nruj kom tiv thaiv kev ntxhov siab thermal hauv cov khoom siv los ntawm kev ua kom sov sai dhau, uas tuaj yeem ua rau tawg lossis tsis zoo rau lwm yam khoom. Tshwj xeeb tshaj yog nyob rau theem pib, yuav tsum siv txoj hauv kev ua kom sov qeeb, nrog rau tus nqi cua sov ntawm 50-100 ℃ ib teev yog qhov tsim nyog. Thaum lub cub tawg kub mus txog ib qib thiab cov qauv sab hauv ntawm cov khoom ruaj khov, tus nqi cua sov tuaj yeem nce ntxiv kom tsim nyog.
Kev Saib Xyuas Kub Kom Zoo Tshaj Plaws: Siv cov cuab yeej ntsuas kub uas muaj qhov tseeb siab los saib xyuas qhov kub hloov pauv hauv lub cub tawg tam sim ntawd. Yog tias qhov kub hloov pauv ntau tshaj qhov tso cai, yuav tsum tau daws teeb meem tam sim ntawd, thiab yuav tsum tau hloov kho lub zog cua sov lossis cov xov hlau ntawm lub tshuab cua sov kom tiv thaiv cov tshuaj lom neeg tshwm sim los ntawm qhov kub tsis zoo.
Kev Ua Kom Sov Sov Sib Npaug: Thaum lub sijhawm ua graphitization, nws yog ib qho tseem ceeb kom ntseeg tau tias qhov kub thiab txias sib npaug hauv lub cub tawg kom tsis txhob kub dhau lossis tsis kub txaus. Qhov no tuaj yeem ua tiav los ntawm kev ua kom zoo dua cov qauv ntawm lub cub tawg, txhim kho qhov kev teeb tsa ntawm cov khoom cua sov, thiab siv txoj kev thauj khoom tsim nyog. Kev ua kom sov sib npaug pab txo qhov kev ntxhov siab thermal hauv cov khoom siv thiab txo qhov kev pheej hmoo ntawm kev tsis zoo nrog lwm yam khoom.
Xaiv Cov Khoom Siv Resistive Tsim Nyog: Thaum qhov kev tiv thaiv ntawm cov khoom siv resistive txawv ntawm cov khoom, cov khoom siv resistive tsim cov cua sov ntau dua li cov khoom nws tus kheej thaum lub sijhawm graphitization electrification, ua rau muaj qhov sib txawv ntawm qhov kub thiab txias ntawm sab hauv thiab sab nraud ntawm cov khoom. Qhov no tuaj yeem ua rau muaj kev ntxhov siab thermal ntau dhau, ua rau tawg lossis tsis zoo nrog lwm yam khoom hauv cov khoom. Yog li ntawd, cov khoom siv resistive nrog qhov resistivity zoo ib yam li cov roj av graphitized coke yuav tsum tau xaiv, thiab yuav tsum tau sib xyaw kom zoo kom txo qhov sib txawv ntawm qhov cua sov thoob plaws ntau qhov ntawm lub hauv paus cua sov.
Kev Tswj Xyuas Cov Khoom Uas Muaj Tsis Huv: Cov khoom uas muaj tsis huv hauv cov roj av coke uas muaj graphitized, xws li sulfur, oxygen, thiab nitrogen, feem ntau yuav ua rau muaj kev cuam tshuam nrog lwm cov khoom ntawm qhov kub siab, ua rau muaj cov tshuaj uas ua rau puas tsuaj rau kev tsim khoom. Yog li ntawd, cov khoom uas muaj tsis huv ntawm cov roj av coke yuav tsum tau tswj hwm nruj me ntsis thaum lub sijhawm tsim khoom, nrog rau kev saib xyuas tshwj xeeb kom khaws cov khoom sulfur kom tsawg (piv txwv li, qis dua 1.0%) kom txo cov teebmeem tsis zoo rau lwm cov khoom hauv lub cub tawg.
Kev Siv Kev Txias Kom Tsim Nyog: Theem txias tom qab graphitization kuj tseem ceeb ib yam thiab yuav tsum tsis txhob saib tsis taus. Yuav tsum siv kev sib xyaw ua ke ntawm kev txias ntuj thiab kev pab cua txias. Ua ntej, yuav tsum tua lub zog cua sov, cia lub cub tawg txias qeeb qeeb hauv ib puag ncig ntuj rau ib lub sijhawm. Thaum qhov kub ntawm lub cub tawg poob qis mus rau ib qib twg, cov khoom siv cua txias tuaj yeem qhib kom maj mam txo qhov kub ntawm lub cub tawg mus rau qhov kub hauv chav. Kev txias sai sai tuaj yeem ua rau cov khoom siv hauv lub cub tawg thiab cov qauv ntawm lub cub tawg puas tsuaj los ntawm kev kub ntxhov, cuam tshuam rau lub neej ua haujlwm ntawm cov khoom siv thiab qhov zoo ntawm cov khoom.
Kev Txhim Kho Cov Khoom Siv: Tshawb xyuas thiab tswj xyuas lub cub tawg graphitization thiab nws cov khoom siv cuam tshuam kom ntseeg tau tias cov khoom siv xws li cov khoom siv cua sov, cov ntsuas kub, thiab cov foob ntawm lub cub tawg ua haujlwm zoo li qub. Yuav tsum hloov cov khoom siv uas puas lawm raws sijhawm kom tiv thaiv cov teeb meem xws li qhov kub tsis zoo lossis cov roj xau los ntawm kev ua tsis tiav ntawm cov khoom siv, yog li txo qhov kev pheej hmoo ntawm kev tsis haum tshuaj nrog lwm yam khoom hauv lub cub tawg.
