Uma imikhiqizo yensimbi ivezwa emoyeni nasemoyeni isikhathi eside, isengozini kalula yokugqwala kwe-oxidative, okuholela ekugqwaleni ebusweni bensimbi.
Ukuze kuxazululwe inkinga yokugqwala kwensimbi, abantu basungula upende wokulwa nokugqwala. Izimiso zawo zokulwa nokugqwala zihlanganisa kakhulu isimiso sokuvimbela kanye nesimiso sokuvikela i-cathodic.
Okokuqala, esinye sezimiso zokulwa nokugqwala zopende olulwa nokugqwala yisimiso sokuvimbela. Upende olulwa nokugqwala luqukethe izinto ezingakha ifilimu evikelayo. Le filimu evikelayo ingamboza ubuso bensimbi, ivimbele umoya nomhwamuko wamanzi futhi ivimbele ukuthi ingagqwali insimbi. Lolu ngqimba lwefilimu evikelayo ludlala indima ekuhlukaniseni insimbi endaweni engaphandle, ngaleyo ndlela lwandise impilo yenkonzo yemikhiqizo yensimbi.
Esinye isimiso sokuvimbela ukugqwala yisimiso sokuvikelwa kwe-cathodic. Upende wokulwa nokugqwala uvame ukuba nama-ion athile ensimbi. Lawa ma-ion ensimbi angakha isithiyo se-electrochemical esivikelayo ebusweni bensimbi, aguqule insimbi ibe yi-anode, ngaleyo ndlela anciphise ukusabela kwe-oxidation ebusweni bensimbi futhi anciphise izinga lokugqwala kwensimbi. Lo pende wokulwa nokugqwala ungakha ukuvikelwa kwe-cathodic njenge-zinc, i-aluminium nezinye izinsimbi, ngaleyo ndlela kufezwe ukuvimbela ukugqwala okusebenzayo kwezinsimbi.
Ngokuvamile, isimiso sokulwa nokugqwala sopende wokulwa nokugqwala sibambezela kakhulu ukuvela kokugqwala kwensimbi ngokuvikelwa kwesithiyo kanye ne-cathodic, futhi sivikela ikhwalithi kanye nempilo yesevisi yemikhiqizo yensimbi. Ngakho-ke, ekusetshenzisweni kobunjiniyela bangempela, kubaluleke kakhulu ukukhetha upende wokulwa nokugqwala ofanele, ongakhulisa impilo yemikhiqizo yensimbi futhi unciphise izindleko zokulungisa.
