Graphite electrodes, nrog rau lawv cov khoom tshwj xeeb ntawm lub cev thiab tshuaj lom neeg, ua lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub no. Raws li cov khoom siv tseem ceeb, graphite electrodes muaj cov yam ntxwv ntawm kev ua haujlwm siab, thermal stability, muaj zog tshuaj lom neeg ruaj khov thiab ua haujlwm yooj yim.
Ua ntej ntawm tag nrho cov, graphite electrodes muaj siab conductivity. Graphite yog ib tug zoo conductor, thiab nws conductivity yog thib ob rau hlau, thiab nyob rau hauv tej yam nws tseem zoo dua li ib co hlau. Cov yam ntxwv no ua rau graphite electrodes dav siv hauv kev lag luam hluav taws xob, kev lag luam hluav taws xob, thiab lwm yam.
Thib ob, graphite electrodes muaj thermal stability. Graphite muaj qhov siab melting point thiab muaj peev xwm tswj tau qhov kev ruaj ntseg ntawm nws cov qauv thiab kev ua tau zoo nyob rau hauv qhov kub thiab txias los yog ultra-siab kub ib puag ncig, uas ua rau graphite electrodes dav siv nyob rau hauv high kub industries xws li kub metallurgy thiab iav manufacturing.
Tsis tas li ntawd, graphite electrodes muaj tshuaj lom neeg ruaj khov. Graphite muaj corrosion kuj zoo rau feem ntau cov kua qaub, alkalis thiab cov kuab tshuaj organic, uas ua rau graphite electrodes dav siv hauv kev lag luam tshuaj, kev lag luam tiv thaiv ib puag ncig thiab lwm yam.
Thaum kawg, graphite electrodes yog ib qho yooj yim rau txheej txheem. Graphite yog mos thiab yooj yim rau txiav, carve thiab cov duab, uas ua rau graphite electrodes muaj kev yooj yim thiab yooj yim rau kev tsim khoom.
