Vim li cas thiaj li graphite ib qho zoo electrode?

Graphite yog suav hais tias yog ib qhoCov khoom siv zoo heev rau kev siv raws li electrodeVim nwsTshwj xeeb ua ke ntawm lub cev, tshuaj, thiab hluav taws xob cov khoom siv, Uas ua rau nws tsim hluav taws xob thiab muaj hluav taws xob rau hauv cov ntawv thov kev lag luam.

Cov laj thawj tseem ceeb vim li cas graphite yog ib qho zoo heev electrode:

1. ​Zoo hluav taws xob conductivity​

Graphite muajDawb Delocalized electronsHauv nws cov qauv txheej txheem, uas tso cai rau nwsCaj hluav taws xob ua tau zoo, Tshwj xeeb tshaj yog raws cov dav hlau ntawm nws txheej carbon txheej.

Thaum tsis yog ua raws li tus qauv ua hlau zoo li tooj liab, graphite tseem muajTxaus siab tauRau siab - Cov ntawv thov tam sim no xws li hluav taws xob arc thiab electrolysis.

2. ​Siab melting taw tes (~ 3,600 degree)​

Graphite tuaj yeem tiv thaivTsis tshua muaj cua sovTsis muaj melting lossis poob nws cov khoom.

Qhov no ua rau nws zoo rau kev siv hauvFais arc rauv (EAF)Qhov twg kub tuaj yeem tshaj3,000 degree, Raws li nws tsis demrade lossis vaporize yooj yim zoo li ntau cov hlau yuav.

3. ​Thermal Stability & Kuj rau Taus Poob​

Graphite cov khoom pov thawjZoo heev Thermal ruaj khov, Tswj nws daim ntawv thiab cov khoom txawm nyob rau hauv cov kev hloov pauv kub.

Nws tawm tsamTawg lossis tawgThaum raug cov cua sov thiab cua txias -} Qhov tshwm sim tshwm sim hauv cov txheej txheem.

4. ​Tshuaj lom neeg inertness​

Graphite yogChemically ruaj khovThiabTsis - eheatriveNyob rau hauv ntau qhov chaw, tshwj xeeb tshaj yog nyob rau hauvTsis - ecidizing tej yam​.

Nws tsis yooj yim hnov ​​mob nrog molten cov hlau, swb, lossis electrolytes, kom ua paug rau cov txheej txheem lossis degrade sai.

5. ​Txhua yam zog ntawm kev kub siab​

Tsis zoo li cov ntaub ntawv feem ntau uas ua brittle lossis tsis muaj zog thaum muaj kub, graphite khawsZOO TXHUA YAM KEV PAB HEEV, Tso cai rau nws los tuav cov qauv kev cai lij choj hauv kev thov cov ntawv thov.

6. ​Self - Lubricatingcua Lub Zog (Nyiaj)​

Txawm hais tias tsis cuam tshuam ncaj qha rau nws lub luag haujlwm ua cov electrode, graphite'sTxheej txheej txheej tso cai tso cai rau txheej kom swb dua ib leeg yooj yim, Muab nws ntuj lub zog hluav taws xob. Qhov no yog pab tau nyob rau hauv qee cov ntawv thov hluav taws xob elevices.

7. ​Luam ntawv​

Graphite tuaj yeem yogMachined rau hauv cov duab ncaj thiab ntau thiab tsawg, Suav nrogPas nrig, thooj kheej kheej, thiab cov geometriesXav tau rau cov khoom siv khoom lag luam.
