Uamea paipa uameao le tulaga o le uʻamea uʻamea zinc ma uʻamea substrate tali o le apa uʻamea, ina ia o le substrate ma le tuufaatasiga o le ufiufi o mea uma e lua.I luga o le faaaogaina o tekinolosi i u'amea, Hot dip galvanized muamua faia le pickling, ina ia aveese le uamea luga o le u'amea oxide, ina ua uma ona pikiina, e ala i se vaifofo vai o le ammonium chloride po o le zinc chloride po o le ammonium chloride ma chlorinated zinc fefiloi vai vaifofo tane. mo le fa'amamāina, ona fa'aulu ai lea i totonu o le ta'ele vevela.Hot-dip galvanized ma faʻaofuofu tutusa, adhesion malosi, ola umi ma isi tulaga lelei.O le mea lea, o auala e ala i le vevela vevela u'amea substrate u'amea ma le taele u'amea e ala i le lavelave faaletino, fa'a'ave'avega fa'ama'i, le fa'avaeina o se fa'amea fa'afefete-fa'a'ala'au zinc-alloy o fausaga fa'atusatusa.O le mea lea, uamea u'amea apa u'amea ma apa o le zinc mama, uamea faʻafefiloi faʻavae e mafai ai ona teteʻe le corrosion.
Zinc chemical lively sex e maualuga atu nai lo uʻamea, pe a tupu electrochemical corrosion, o le corrosion muamua o le zinc nai lo le uʻamea, zinc oxide ma fai si faʻatusatusa, lea e mafai ona taofia atili oxidation.E masani lava uamea galvanized i corrosion tetee lelei, corrosion o tanumia uamea ua vaevaeina i ni ituaiga se lua o toniga corrosion ma localized corrosion, localized corrosion tele lava pulea, o le tulaga matautia e sili.u'amea u'amea i le eleele electrochemical dissolution faagasologa e masani lava ona o le fausia o sela corrosion e mafua ai paipa corrosion perforation.Oomi le corrosion cell anode ma cathode spacecing tele, ae faʻapipiʻi foi le uamea i micro-cell corrosion corrosion ma macro cell corrosion lua vaega.Electrochemical corrosion mo tanumia paipa faagasologa, uamea corrosion inhibition auala e amata ai se faagasologa.Afai o le paipa puipui faʻatasi ai ma le faʻapipiʻiina o mea e faʻafefete ai, e mafai ona faʻateleina le teteʻe o matasele, faʻaitiitia ai le pala;fafo DC mana sapalai, ina ia mafai ona aveesea le paipa palapala e mafua ai le gafatia le lelei, le fausia o le cathodic puipuiga anode eseesega gafatia e mafai ona aveesea mai le aʻa e taofi le faagasologa o le anode ma cathode faaauau.Ae o le taimi lava e faaleagaina ai le ufiufi anti-corrosion, o vaega uʻamea faʻaalia o le a faʻavaveina ai le pala.O le mea lea, o le anti-corrosion coating ma le cathodic puipuiga faʻatasi faʻaumatia lenei metotia o le laulau, taugofie ma aoga.
