Vim li cas cov txheej txheem kev kho cua sov tshwj xeeb rau cov txheej txheem graphite tsim nyog?

Txheej txheem kho cua sov tshwj xeeb rau Graphite cov hluav taws xob tsis yog ib feem ntawm kev tsim khoom, tab sis kuj tseem ceeb rau kev ua kom zoo dua qub nws ua tau zoo. Nov yog cov laj thawj tshwj xeeb rau nws qhov kev xav tau:

1. Optimizing microstructure

Cov kev ua yeeb yam ntawm graphite electrodes yog ze ze rau nws microstructure. Txheej txheem kev kho cua sov tshwj xeeb txhawb kev hloov pauv cov roj carbon a atoms, thermal conductivity, thiab tshuab zog thiab tshuab zog. Tus txheej txheem no yuav tsum muaj tseeb tswj tau qhov kub thiab sijhawm los ua kom muaj kev sib txawv thiab kev ruaj ntseg ntawm microstructure.

2. Nce Khoom Siv Hluav Taws Xob

Graphite electrodes xav tau siab rau siab - sov daim ntawv thov kom txo porosity thiab txhim kho tshuab zog thiab oxidation tsis kam. Cov txheej txheem kev kho cua sov tshwj xeeb zoo ua rau cov khoom siv ceev kom nruj los ntawm kev tshem tawm cov zaub pob thiab txhawb nqa cov khoom siv hluav taws xob, cov khoom siv hluav taws xob.

3. Txo thermal expansion coefficient

Graphite electrodes yog nquag rau kev nyuaj siab -}}} tsis muaj kev tawg lossis deformation vim muaj kev nthuav dav ntawm qhov kub. Cov txheej txheem kev kho vaj kub tshwj xeeb ua rau cov qauv siv ua kom muaj cov roj carbon, txo nws cov kev cuam tshuam ntawm kev ntxhov siab ntawm kev kub ntxhov.

4. Txhim Kho Oxidation Kuj

Graphite cov ntawv hluav taws xob yog cov tshuaj tiv thaiv oxidation nyob rau hauv high - qhov kub thiab txias oxidizing ib puag ncig, coj mus rau saum npoo degradation thiab kev ua haujlwm poob qis. Txheej Txheem Tshwj Xeeb Kev Kho Mob Kub Kub Tshwj Xeeb txhim kho los ntawm kev ua kom zoo dua cov qauv siv lead ua kom zoo nkauj thiab nce ntxiv hluav taws xob lub neej.

5. Lub rooj sib tham muaj ntau yam kev thov sau ua ke

Graphite hluav taws xob tau siv nyob rau hauv ntau cov ntawv thov, txhua tus nrog cov kev xav tau sib txawv. Los ntawm cov txheej txheem kho cua sov tshwj xeeb, hluav taws xob conductivity, thiab cov neeg kho mob muaj zog ntawm cov cai tau ua tiav, ua rau lawv zoo dua rau cov chaw ua haujlwm txawv.
