Ntawm no yog ib qho kev sib cais ntawm qhov sib txawv:
Graphite
Txhais: Graphite yog ib qho kev tshwm sim ntawm cov pa roj carbon monoxide uas ua los ntawm nws cov txheej txheem txheej. Nws yog crystalline allotrope ntawm carbon thiab paub txog nws cov hluav taws xob zoo heev, lubricating zog, thiab thermal stability.
Cov khoom:
Hluav taws xob conductivity: Siab, ua kom haum rau kev siv hluav taws xob.
Thermal conductivity: Tsis tas li ntawd siab, tso cai rau kom muaj cua sov dissipation.
Lubrication: Nws muaj lubricating zoo heev vim nws cov txheej txheem txheej.
Tshuaj Stability: Resistant rau ntau cov tshuaj tiv thaiv, tab sis tuaj yeem oxidized ntawm qhov kub thiab txias.
Cov ntawv: Graphite tuaj yeem pom nyob rau hauv ntau hom, xws li hmoov, flakes, lossis raws li cov khoom thaiv (natural graphite) thiab tuaj yeem ua hluavtaws.
Hluav taws xob
Txhais: Ib qho electrode yog tus neeg xyuas pib los ntawm cov hluav taws xob tam sim no nkag los yog tawm hauv nruab nrab (xws li electrolyte lossis roj). Electrodes yog siv nyob rau hauv ntau yam kev siv hluav taws xob thiab electrochemical, xws li roj teeb, capacitors, thiab electrochemical hlwb.
Hom: Muaj ntau hom electrodes, nyob ntawm lawv txoj haujlwm:
Anodes: Electrodes qhov twg oxidation tshwm sim (poob ntawm electrons).
Cathodes: Electrodes qhov twg txo tau tshwm sim (tau txais ntawm electrons).
Siv Electrodes: Siv los ntsuas qhov muaj peev xwm hauv cov hlwb electrochemical.
Khoom siv: Electrodes tuaj yeem tsim los ntawm ntau yam ntaub ntawv, suav nrog hlau (xws li platinum lossis tooj liab), cov khoom siv carbon, thiab cov khoom siv hluavtaws. Graphite electrodes yog ib hom electrode uas ua los ntawm graphite.
Qhov txawv tseem ceeb
Xwm: Graphite yog cov khoom siv (tshwj xeeb yog cov pa roj carbon), thaum lub electrode yog cov khoom siv ua haujlwm siv hauv kev siv hluav taws xob.
Muaj nuj nqi: Lub hom phiaj tseem ceeb ntawm electrodes yog los pab txhawb kev khiav ntawm hluav taws xob tam sim no rau hauv lossis tawm ntawm qhov nruab nrab hauv cov khoom siv xws li roj teeb thiab cov hluav taws xob hluav taws xob. Graphite lub luag haujlwm ua cov khoom siv electrode yog vim nws cov khoom siv hluav taws xob.
Daim ntawv thov: Thaum graphite tuaj yeem siv tau rau hauv ntau daim ntawv thov (xws li roj nplua nyeem, roj teeb, thiab cov khoom siv), cov khoom siv hluav taws xob feem ntau yog siv hauv cov khoom siv hluav taws xob thiab hluav taws xob.
