Sidee birta uga hortagtaa miridhku?

Marka alaabta birta ahi ay muddo dheer hawada iyo uumiga biyaha soo gaadhaan, waxa ay si fudud ugu nugul yihiin daxalka oksaydhiyaha, taas oo keenta miridhku dusha birta ah.

Si loo xalliyo dhibaatada daxalka birta, dadku waxay abuureen rinji ka hortagga miridhku.Mabaadi'da ka hortagga miridhku inta badan waxa ka mid ah mabda'a xannibaadda iyo mabda'a ilaalinta cathodic.

Ugu horreyntii, mid ka mid ah mabaadi'da ka hortagga miridhku ee rinjiga ka hortagga miridhku waa mabda'a xannibaadda.Rinjiga ka-hortagga miridhku wuxuu ka kooban yahay walxo samayn kara filim difaac ah.Filimkan difaaca ayaa dabooli kara birta dushiisa, isaga oo xannibaya hawada iyo uumiga biyaha kana hortagaya in ay daxaliyaan birta.Lakabka filimka difaaca ayaa door ka ciyaara ka soocida birta ee deegaanka dibadda, taas oo kordhinaysa nolosha adeegga alaabta birta ah.

Mabda'a kale ee ka hortagga miridhku waa mabda'a ilaalinta cathodic.Rinjiga ka-hortagga sida caadiga ah wuxuu ka kooban yahay ion bir ah oo gaar ah.Iions-yadan biraha ah waxay samayn karaan xannibaad koronto kiimikaad oo ilaalinaya oogada birta, birtana u roga anode, taas oo yaraynaysa falcelinta oksaydhka ee dusha birta waxayna hoos u dhigtaa heerka daxalka birta.Rinjigaan ka-hortagga miridhku wuxuu samayn karaa ilaalinta cathodic sida zinc, aluminium iyo biraha kale, si loo gaaro ka-hortagga miridhku wax ku ool ah ee biraha.

Guud ahaan, mabda'a ka-hortagga miridhku ee rinjiga ka-hortagga miridhku wuxuu inta badan dib u dhigayaa dhacdada daxalka birta iyada oo loo marayo xannibaadda iyo ilaalinta cathodic, waxayna ilaalisaa tayada iyo nolosha adeegga alaabta birta.Sidaa darteed, codsiyada injineernimada dhabta ah, aad bay muhiim u tahay in la doorto rinjiga ka hortagga miridhku ku habboon yahay, kaas oo kor u qaadi kara nolosha alaabta birta ah oo yaraynaysa kharashka dayactirka.
