Elektroodhada Garaafiga

Elektroodhada graphite waxaa inta badan loo isticmaalaa wax soo saarka birta foornada korantada sababtoo ah waxay leeyihiin sifooyin koronto oo sarreeya.

Sharaxaad

Elektroodhada garaafiga hadda waa alaabada kaliya ee la heli karo ee leh heerarka sare ee korantada iyo awoodda ay ku ilaalin karaan heerarka aadka u sarreeya ee kulaylka ka dhasha jawigan adag. Waxaa loo isticmaalaa in lagu sifeeyo birta foornadaha iyo hababka kale ee dhalaalinta. Kuwani waxay u dhaqmaan sidii gudbiyeyaal koronto oo foornada ku jira, iyagoo soo saaraya kulayl ku filan oo dhalaaliya birta qashinka ah, macdanta birta ama walxaha kale ee ceeriin ah ee loo isticmaalo soo saarista birta ama biraha kale. Foornada caadiga ah ee isticmaaleysa hadda beddelan oo ku shaqeysa tiro wareegyo wax soo saar caadi ah maalintii, mid ka mid ah sagaalka elektroodh ayaa si buuxda loo isticmaalaa (oo u baahan in lagu daro elektroodh cusub), celcelis ahaan, siddeed ilaa toban saacadood oo shaqo ah. Heerka dhabta ah ee isticmaalka iyo ku darista elektroodhada foornada gaarka ah waxay ku xiran tahay inta badan hufnaanta iyo wax soo saarka foornada.
