Lapho imikhiqizo yensimbi ivezwa emoyeni nasemoyeni wamanzi isikhathi eside, isengozini kalula ekugqwaleni kwe-oxidative, okuholela ekugqwaleni endaweni yensimbi.
Ukuze kuxazululwe inkinga yokugqwala kwensimbi, abantu basungula upende ovimbela ukugqwala.Izimiso zayo zokulwa nokugqwala ikakhulukazi zihlanganisa isimiso sokuvimbela kanye nomgomo wokuvikela i-cathodic.
Okokuqala, enye yezimiso zokulwa nokugqwala kwepende yokugqwala iyisimiso sokuvimbela.I-anti-rust paint iqukethe izinto ezingakha ifilimu yokuzivikela.Le filimu yokuvikela ingamboza indawo yensimbi, ivimbe umoya nomhwamuko wamanzi futhi ivimbele ekugqwaliseni insimbi.Lolu ngqimba lwefilimu yokuzivikela ludlala indima ekuhlukaniseni insimbi endaweni yangaphandle, ngaleyo ndlela yandise impilo yesevisi yemikhiqizo yensimbi.
Esinye isimiso sokuvimbela ukugqwala isimiso sokuvikelwa kwe-cathodic.I-antirust paint ngokuvamile iqukethe ama-ion ensimbi athile.La ma-ion ensimbi angakha umgoqo ovikelayo we-electrochemical endaweni yensimbi, aguqule insimbi ibe i-anode, ngaleyo ndlela ehlise ukusabela kwe-oxidation endaweni yensimbi futhi ehlise izinga lokugqwala kwensimbi.Lo pende ovimbela ukugqwala ungakha ukuvikelwa kwe-cathodic njenge-zinc, i-aluminium nezinye izinsimbi, ngaleyo ndlela kuzuzwe ngempumelelo ukuvimbela ukugqwala kwezinsimbi.
Ngokuvamile, isimiso sokulwa nokugqwala sopende ovimbela ukugqwala sibambezela ikakhulukazi ukwenzeka kokugqwala kwensimbi ngokusebenzisa umgoqo kanye nokuvikelwa kwe-cathodic, futhi sivikela ikhwalithi nempilo yesevisi yemikhiqizo yensimbi.Ngakho-ke, ekusetshenzisweni kwangempela kobunjiniyela, kubaluleke kakhulu ukukhetha upende olufanele lokulwa nokugqwala, olungakhulisa impilo yemikhiqizo yensimbi futhi lunciphise izindleko zokunakekela.
