Qhov kev ruaj khov ntawm qhov kub siab ntawm cov electrodes graphite yog li cas?

Cov hluav taws xob graphite qhia tau tias muaj kev ruaj khov zoo heev thaum kub siab, nrog rau qhov kub yaj txog li 3652 ° C, ua rau lawv yog ib qho ntawm cov khoom siv uas muaj cov ntsiab lus yaj siab tshaj plaws. Cov yam ntxwv no ua rau lawv tswj tau qhov ruaj khov ntawm cov qauv thiab kev ua tau zoo hauv qab qhov kub siab, ua rau lawv yog cov khoom siv tseem ceeb hauv cov teb xws li metallurgy, chemical engineering, thiab lub zog tshiab. Cov kev tshuaj xyuas hauv qab no delves rau hauv peb yam: cov tsos mob tshwj xeeb, cov xwm txheej siv, thiab cov yam ntxwv cuam tshuam.

I. Cov Kev Qhia Tshwj Xeeb ntawm Kev Ruaj Ntseg Kub Siab

1. Kev Ruaj Ntseg ntawm Cov Qauv: Cov hluav taws xob graphite tsis yooj yim hloov pauv lossis lwj thaum kub siab. Lawv cov qauv crystalline uas muaj txheej txheem tuaj yeem tiv taus qhov kub ntawm ntau txhiab degrees Celsius yam tsis muaj kev tawg lossis deformation.
2. Kev Ruaj Ntseg ntawm Kev Ua Haujlwm: Hauv qhov chaw kub siab, cov cim qhia kev ua tau zoo tseem ceeb ntawm cov electrodes graphite, xws li kev ua hluav taws xob, kev ua cua sov, thiab lub zog kho tshuab, tseem ruaj khov thiab tsis poob qis nrog qhov kub nce ntxiv.
3. Kev Ruaj Ntseg Tshuaj: Cov hluav taws xob graphite ua pov thawj tias lawv tiv taus xeb zoo rau feem ntau cov kua qaub, alkalis, thiab cov kuab tshuaj organic, thiab tswj lawv txoj kev ua haujlwm ruaj khov txawm tias nyob hauv qhov kub siab heev los ntawm kev kub hnyiab ntawm cov tshuaj.

II. Kev Siv Cov Kev Ruaj Ntseg Kub Siab Hauv Kev Lag Luam

1. Kev Ua Haujlwm Hlau: Hauv cov txheej txheem ua hlau hluav taws xob arc, cov electrodes graphite yuav tsum tiv taus qhov kub tshaj 2000 ° C thiab txuas ntxiv ua cov hluav taws xob siab los tsim cov arc tawm. Lawv qhov kev ruaj khov kub siab ua kom ntseeg tau tias kev ua haujlwm txuas ntxiv thiab ua haujlwm tau zoo ntawm cov txheej txheem smelting thaum txo cov nqi siv electrode.
2. Kev Ua Haujlwm Txog Tshuaj Lom Zem: Hauv cov txheej txheem xws li electrolysis ntawm brine thiab sodium oxide, graphite electrodes ua haujlwm ua cov khoom tseem ceeb hauv cov electrolytic cells thiab yuav tsum ua haujlwm nyob rau hauv qhov kub thiab txias thiab muaj zog corrosive rau lub sijhawm ntev. Lawv qhov kub thiab txias thiab tshuaj lom neeg ruaj khov lav qhov ruaj khov ntawm cov txheej txheem electrolysis thiab qhov huv ntawm cov khoom.
3. Lub Zog Tshiab: Hauv cov roj teeb lithium-ion, cov electrodes graphite, siv ua cov khoom siv anode, yuav tsum tiv taus qhov kub siab thiab kev cuam tshuam tam sim no thaum lub sijhawm them thiab tso tawm. Lawv qhov kev ruaj khov ntawm qhov kub siab pab txhawb kev txhim kho kev ua haujlwm ntawm lub roj teeb thiab kev nyab xeeb. Cov electrodes graphite kuj tseem siv dav hauv cov teb xws li lub hnub ci photovoltaics, kev tsim hluav taws xob cua, thiab cov roj teeb vim lawv qhov kev ruaj khov ntawm qhov kub siab.

III. Cov Yam Uas Cuam Tshuam Rau Kev Ruaj Ntseg Kub Siab

1. Qhov Zoo ntawm Cov Khoom Siv Raw: Qhov ruaj khov ntawm cov graphite electrodes thaum kub siab muaj feem cuam tshuam nrog qhov zoo ntawm lawv cov khoom siv raw. Cov khoom siv graphite uas muaj qhov huv si thiab muaj qhov ceev ceev tuaj yeem ua rau cov electrodes tiv taus kub siab dua.
2. Cov Txheej Txheem Tsim Khoom: Cov txheej txheem tsim cov graphite electrodes, suav nrog qhov kub thiab txias ntawm graphitization, lub sijhawm, thiab kev siv cov khoom ntxiv, cuam tshuam rau lawv qhov kev ruaj khov hauv qhov kub siab. Kev ua kom zoo tshaj plaws ntawm cov txheej txheem tsim khoom tuaj yeem txhim kho qhov ceev thiab kev sib xws ntawm cov electrodes, yog li ua kom lawv qhov kev ruaj khov hauv qhov kub siab.
3. Ib puag ncig ua haujlwm: Ib puag ncig uas siv cov graphite electrodes, xws li qhov kub thiab txias, huab cua, thiab qhov ceev ntawm cov hluav taws xob, kuj cuam tshuam rau lawv qhov kev ruaj khov ntawm qhov kub thiab txias. Kev tswj hwm ib puag ncig ua haujlwm kom zoo tuaj yeem ua rau cov electrodes siv tau ntev dua.
