Yuav muaj tej qhov tsis zoo uas tsis kho tau li cas hauv cov txheej txheem graphitization tom qab ntawd vim yog "kev hlawv tsis txaus" calcination?

Cov coke uas raug hlawv tsis tau zoo, vim tsis muaj calcination txaus ntawm cov khoom siv raw, yuav ua rau muaj qhov tsis zoo ntawm cov qauv sab hauv thaum lub sijhawm graphitization tom qab, uas ua rau muaj qhov tsis zoo uas tsis tuaj yeem rov qab tau xws li tawg, qhov ceev tsis sib xws, qhov ntim tsis zoo, thiab kev ua haujlwm tsis zoo hauv cov khoom graphitized. Kev tshuaj xyuas ntxaws ntxaws yog raws li nram no:

Kev Cuam Tshuam Ncaj Qha ntawm Kev Tsis Txaus Calcination ntawm Cov Khoom Siv Raw

Ua ntej calcination, calcination yog ib kauj ruam tseem ceeb ua ntej graphitization, uas yog kom cov khoom siv raw (xws li petroleum coke thiab needle coke) tawm hauv qhov kub siab, txo cov khoom tsis huv, thiab tsim cov qauv pore kom zoo. Yog tias calcination tsis txaus (piv txwv li, "hlawv tsis txaus"), yuav muaj ntau cov khoom tsis huv thiab cov khoom tsis huv uas tsis tau ua haujlwm nyob hauv cov khoom siv raw. Cov seem no yuav txuas ntxiv mus lwj lossis ua rau muaj kev cuam tshuam thaum lub sijhawm graphitization tom qab, ua rau muaj roj tawm lossis hloov pauv tshuaj hauv cov khoom, ua rau muaj kev puas tsuaj ntawm cov qauv.

Cov Kev Tsis Zoo Uas Tsis Rov Qab Tau Tsim Thaum Lub Sijhawm Graphitization

Qhov Tawg:

• Ua rau muaj kev tsim: Cov tshuaj uas tsis muaj zog thiab cov khoom tsis huv uas nyob hauv cov coke uas raug hlawv tsis tau kub hnyiab sai sai lossis ua rau muaj kev kub ntxhov thaum lub sijhawm graphitization, ua rau muaj roj ntau heev. Cov roj no sib sau ua ke hauv cov khoom thiab nrhiav txoj kev khiav tawm; yog tias nws tsis tuaj yeem raug tshem tawm raws sijhawm, nws tsim kom muaj kev siab siab hauv cov khoom, ua rau muaj kev tawg. Tsis tas li ntawd, cov qauv tsis sib xws ntawm cov coke uas raug hlawv tsis tau kub hnyiab tuaj yeem ua rau muaj kev faib tawm ntawm kev ntxhov siab thermal tsis sib xws thaum lub sijhawm graphitization, ua rau muaj kev tawg ntxiv.
• Kev Cuam Tshuam: Cov kab nrib pleb txo qhov muaj zog thiab kev ua hluav taws xob ntawm cov khoom thiab tej zaum yuav ua rau nws tawg thaum lub sijhawm ua lossis siv tom qab.

Qhov Ceev Tsis Sib Npaug:

• Vim Li Cas Thiaj Tsim Tau: Cov qauv ntawm cov qhov tsis sib xws ntawm cov coke uas raug hlawv tsis zoo ua rau cov khoom txav mus los thiab ua kom ntom thaum lub sijhawm graphitization. Qee qhov chaw yuav muaj kev ntom tsis txaus vim muaj cov qhov ntau dhau, thaum lwm qhov yuav tsim cov kev ntxhov siab vim muaj kev ntom dhau.
• Kev Cuam Tshuam: Qhov ceev tsis sib npaug cuam tshuam rau cov cim qhia kev ua tau zoo tseem ceeb ntawm cov khoom, xws li kev ua hluav taws xob, kev ua kom sov, thiab lub zog kho tshuab.

Kev Ntsws Ntim Tsis Zoo Li Qub:

• Vim Li Cas Thiaj Tsim Tau: Cov coke uas raug hlawv tsis tau zoo yuav ua rau lub cev me me thaum lub sijhawm graphitization vim yog qhov lwj ntawm cov khoom seem lossis cov tshuaj tiv thaiv ntawm cov khoom tsis huv. Qhov kev me me no tuaj yeem ua rau cov khoom tsis ruaj khov thiab txawm tias deformation.
• Kev Cuam Tshuam: Qhov ntim me me tsis zoo cuam tshuam rau qhov tseeb ntawm qhov ntev thiab kev sib dhos ua ke ntawm cov khoom, txo nws qhov zoo tag nrho.

Kev Ua Haujlwm Poob Qis:

• Vim yog qhov muaj cov qhov tsis zoo uas tau hais los saum toj no, cov khoom lag luam graphitized ua los ntawm cov coke calcined uas tsis kub hnyiab yuav ua rau muaj kev ua hluav taws xob qis dua, kev ua kom sov sov, thiab lub zog kho tshuab qis dua piv rau cov uas ua los ntawm cov coke calcined kom zoo.
• Qhov Cuam Tshuam: Kev ua haujlwm poob qis txwv qhov kev siv thiab lub neej ua haujlwm ntawm cov khoom, txo nws txoj kev sib tw ua lag luam.
