Umbhobho wentsimbi owenziwe ngamachizayimeko yentsimbi etyhidiweyo zinc kunye nentsimbi substrate reaction of ingxubevange umaleko, ukuze substrate kunye indibaniselwano ukutyabeka zombini.Ekusetyenzisweni kobugcisa kwi-galvanized, idiphu eshushu ifakwe kwi-galvanized kuqala ukwenza i-pickling, ukuze kususwe umphezulu wentsimbi ye-iron oxide, emva kokuchola, ngokusebenzisa isisombululo esimanzi se-ammonium chloride okanye i-zinc chloride okanye i-ammonium chloride kunye ne-zinc chlorinated exutywe netanki yesisombululo esimanzi. ukucoca, kwaye emva koko ungene kwibhafu yokucoca eshushu.I-Hot-dip galvanized kunye ne-coating uniform, i-adhesion eyomeleleyo, ubomi obude kunye nezinye izibonelelo.Ke ngoko, ubuchule ngokudipha eshushu isiseko sentsimbi kunye nebhafu etyhidiweyo ngobunzima bomzimba, ukusabela kweekhemikhali, ukwakheka komaleko onganyangekiyo we-zinc-alloy yesakhiwo esibambeneyo.Ke ngoko, umaleko we-alloy yentsimbi kunye nomaleko we-zinc esulungekileyo, umxube wesiseko sentsimbi wenza isakhono sokumelana nomhlwa.

I-Zinc ikhemikhali ye-sex ephilayo iphezulu kune-iron, xa i-electrochemical corrosion isenzeka, i-corrosion yokuqala yi-zinc endaweni ye-iron, i-zinc oxide kunye ne-compact ngokwentelekiso, enokuthi ithintele i-oxidation eyongezelelweyo.Ngokuqhelekileyo intsimbi ekhangayo inokumelana nomhlwa okulungileyo, ukubola kwemibhobho yentsimbi engcwatyiweyo yahlulwe ibe ziindidi ezimbini zomhlwa ofanayo kunye nomhlwa wasekhaya, umhlwa wasekhaya ulawulwa kakhulu, ingozi yeyona inkulu.Ukonakala kwentsimbi kumhlaba wenkqubo yokuchithwa kwe-electrochemical kubangelwe ikakhulu kukwakheka kweeseli zomhlwa okukhokelela ekugqobhozeni kombhobho.Cinezela i-anode ye-corrosion cell kunye nobungakanani besithuba secathode, kodwa umise intsimbi ibe yi-micro-cell corrosion corrosion kunye ne-macro cell corrosion iindidi ezimbini.I-Electrochemical corrosion yenkqubo yombhobho engcwatyiweyo, indlela yentsimbi yokuthintela umhlwa ekuza kuqala ngayo inkqubo.Ukuba udonga lombhobho kunye ne-anti-corrosion coating, ukuchasana kwe-loop kunokunyuswa, ukunciphisa umhlwa wangoku;yangaphandle DC unikezelo lwamandla, ukuze umhlaba umbhobho ebangela amandla angalunganga, ukwakheka cathodic ukhuseleko anode umahluko enokubakho inokupheliswa ingcambu ukumisa inkqubo anode kunye cathode uqhubeke.Kodwa xa i-anti-corrosion coating yonakalisiwe, iindawo zentsimbi eziveziweyo ziyakukhawulezisa ukubola kwendawo.Ngoko ke, i-anti-corrosion coating kunye nokukhuselwa kwe-cathodic edibeneyo ukulahla le ndlela yitafile, izoqoqosho kwaye isebenzayo.
