Ipayipi lensimbi eliphehliweiyisimo se-zinc yensimbi encibilikisiwe kanye ne-iron substrate yokusabela kwe-alloy layer, ukuze i-substrate kanye nenhlanganisela yokunamathela kokubili.Ekusetshenzisweni kobuchwepheshe ku-galvanized, idiphu elishisayo lifaka ugqozi kuqala, ukuze kukhishwe ubuso bensimbi ye-iron oxide, ngemva kokuchotshozwa, ngokusebenzisa isixazululo esinamanzi se-ammonium chloride noma i-zinc chloride noma i-ammonium chloride ne-chlorinated zinc exutshwe nethangi lesisombululo samanzi. ukuze kuhlanzwe, bese kuba okugeza hot-dip Plating.I-Hot-dip efakwe uthayela ngokufana kokunamathela, ukunamathela okuqinile, impilo ende nezinye izinzuzo.Ngakho-ke, amasu by dip hot insimbi yashukumisa substrate kanye okugeza oncibilikisiwe ngokusebenzisa eziyinkimbinkimbi ngokomzimba, amakhemikhali ukusabela, ukwakheka ungqimba ukumelana nokugqwala zinc-alloy isakhiwo compact.Ngakho-ke, i-galvanized steel alloy layer kanye nengqimba ye-zinc ehlanzekile, inhlanganisela yesisekelo sensimbi yenza ikhono lokumelana nokugqwala.

Amakhemikhali e-Zinc ocansini oluphilayo luphakeme kune-iron, lapho ukugqwala kwe-electrochemical kwenzeka, ukugqwala kokuqala yi-zinc esikhundleni se-iron, i-zinc oxide kanye ne-compact kuqhathaniswa, engavimbela ukuqhubekela phambili kwe-oxidation.Ngokuvamile insimbi enothayela inokumelana nokugqwala okuhle, ukugqwala kwamapayipi ensimbi angcwatshwe ihlukaniswe yaba izinhlobo ezimbili zokugqwala okufanayo nokugqwala kwendawo, ukugqwala kwasendaweni okubuswa kakhulu, ingozi inkulu kakhulu.Ukugqwala kwensimbi enhlabathini yenqubo yokuchithwa kwe-electrochemical kubangelwe ikakhulukazi ukwakheka kwamaseli okugqwala okuholela ekugxumeni kwepayipi.Cindezela i-corrosion cell anode kanye nosayizi wesikhala se-cathode, kodwa futhi ulolonge insimbi ibe yi-micro-cell corrosion corrosion kanye ne-macro cell corrosion izigaba ezimbili.I-electrochemical corrosion yenqubo yamapayipi angcwatshwe, indlela yokuvimbela ukugqwala kwensimbi okuqalwa ngayo inqubo.Uma udonga lwamapayipi kanye ne-anti-corrosion coating, ukumelana ne-loop kungandiswa, kunciphise ukugqwala kwamanje;Ukunikezwa kwamandla kagesi kwangaphandle kwe-DC, ukuze ipayipi lomhlabathi elibangela amandla angalungile, ukwakheka komehluko ongaba khona wokuvikela we-cathodic anode kungaqedwa ezimpandeni ukumisa inqubo ye-anode ne-cathode ukuqhubeka.Kodwa uma i-anti-corrosion coating seyonakele, izingxenye zensimbi eziveziwe zizosheshisa ukugqwala kwendawo.Ngakho-ke, i-anti-corrosion coating kanye nokuvikelwa kwe-cathodic okuhlangene nokukhipha le ndlela yitafula, ukonga futhi kusebenza kahle.
