Idiphu eshushu igalelayindlela esetyenziswa ngokubanzi yokukhusela intsimbi kwi-corrosion.Le nkqubo ibandakanya amanyathelo angundoqo aliqela, kubandakanywa unyango lwangaphambili, olubalulekileyo ekuqinisekiseni umgangatho kunye nokuqina kokwaleka kwegalvanized.Inkalo ebalulekileyo yonyango lwangaphambili kukusetyenziswa kwamatanki okuhlamba kunye nokufudumeza ukuyilungiselela inkqubo ye-galvanizing.
Inyathelo lokuqala kwinkqubo ye-galvanizing yediphu eshushuunyango lwangaphambili, okubandakanya ukucoca intsimbi ukususa nayiphi na into engcolileyo enokuthi iphazamise inkqubo ye-galvanizing.Oku ngokuqhelekileyo kwenziwa kwitanki yokucoca, apho intsimbi ifakwe kwisisombululo se-alkaline eshushu ukususa igrisi, ioli okanye ezinye iintsalela zezinto eziphilayo.Itanki yokucoca iyinxalenye ebalulekileyo yeinkqubo yonyango lwangaphambilinjengoko iqinisekisa ukuba intsimbi icocwe ngokucokisekileyo phambi kokuba ifakwe igalvanized.
Emva kokuba intsimbi ihlanjululwe kwitanki yokucoca, ingabaifudunyezwe kwangaphambili.Eli nyathelo libandakanya ukufudumeza intsimbi ukususa naluphi na umswakama oseleyo kwaye ulungiselele umphezulu wenkqubo ye-galvanizing.Ukufudumeza intsimbi kubalulekile njengoko kunceda ukuqinisekisa ukuba i-galvanized coating ibambelela kumphezulu ngokufanelekileyo, okukhokelela ekugqityweni kwexesha elide kunye nexesha elide.
Emva kokuba amanyathelo onyango lwangaphambili lugqityiwe, intsimbi ilungeleeshushu-dip galvanizinginkqubo.Oku kubandakanya ukuntywiliselwa kwentsimbi kwibhafu yezinki etyhidiweyo, ethi idibane ngesinyithi kwintsimbi ukuze yenze isambatho esikhuselayo esikwaziyo ukugxwala.Inkqubo ye-galvanizing yenzeke kumaqondo aphezulu, ngokuqhelekileyo malunga ne-450 ° C (850 ° F), ukuqinisekisa ukuba i-zinc coating bonds ngokufanelekileyo kwintsimbi.
Emva kokuba intsimbi ifakwe i-galvanized, ipholile kwaye ihlolwe ukuqinisekisa ukuba i-coating is even and free of any defects.I-zinc eyongeziweyo isusiwe, kwaye intsimbi ilungele ukusetyenziswa kwezicelo ezininzi, ukusuka kulwakhiwo kunye neziseko ezingundoqo ukuya kwiimoto kunye nezixhobo zoshishino.
Ukushwankathela, inkqubo ye-galvanizing ye-hot-dip ibandakanya amanyathelo abalulekileyo amaninzi, kuqukapre-unyango eshushu-dip galvanizing, ukusetyenziswa kwamatanki okuhlamba, kunye nokufudumeza kwangaphambili unyango.La manyathelo ayimfuneko ukuze kuqinisekiswe ukuba intsimbi ilungiselelwe ngokufanelekileyo inkqubo yokufaka i-galvanizing, okubangela ukuba umgangatho ophezulu, i-coating ehlala ixesha elide enika ukhuseleko olugqwesileyo kwi-corrosion.Ngokulandela la manyathelo, abavelisi banokuqinisekisa ukuba iimveliso zabo zetsimbi ezinobumba zihlangabezana nomgangatho ophezulu kunye nemigangatho yokusebenza.
