Idiphu elishisayo elishisayoiyindlela esetshenziswa kabanzi yokuvikela insimbi ekugqwaleni. Le nqubo ibandakanya izinyathelo ezibalulekile ezimbalwa, okuhlanganisa nokwelashwa kwangaphambili, okubalulekile ekuqinisekiseni ikhwalithi nokuqina kokunamathela kukathayela. Isici esibalulekile sokwelashwa kwangaphambili ukusetshenziswa kwamathangi okwehlisa amafutha kanye nokushisa ukuze kulungiselelwe inqubo yokufaka ama-galvanizing.
Isinyathelo sokuqala senqubo ye-hot-dip galvanizing nguukwelashwa ngaphambi kwesikhathi, okubandakanya ukuhlanza insimbi ukuze kukhishwe noma yikuphi ukungcola okungase kuphazamise inqubo yokufaka ama-galvanizing. Lokhu kuvame ukwenziwa ethangini lokukhipha amafutha, lapho insimbi icwiliswa khona esixazululweni se-alkaline esishisayo ukuze kukhishwe amafutha, uwoyela noma ezinye izinsalela zezinto eziphilayo. I-tank yokuhlanza iyingxenye ebalulekile ye-inqubo yokwelashwa kwangaphambilinjengoba kuqinisekisa ukuthi insimbi ihlanzwa kahle ngaphambi kokuba ifakwe uthayela.
Uma insimbi ihlanzwa ethangini lokukhipha amafutha, ingabaukushisisa kuqala. Lesi sinyathelo sibandakanya ukushisisa insimbi ukuze kususwe noma yimuphi umswakama osele futhi kulungiswe indawo engaphezulu yenqubo yokufaka uthayela. Ukushisa insimbi kubalulekile njengoba kusiza ukuqinisekisa ukuthi i-galvanized coating inamathela endaweni efanele, okuholela ekuqedeni okuhlala isikhathi eside futhi okuhlala isikhathi eside.
Uma izinyathelo zokwelashwa zangaphambili seziqediwe, insimbi isilungelei-hot-dip galvanizinginqubo. Lokhu kuhilela ukucwilisa insimbi kubhavu we-zinc encibilikisiwe, eboshelwa ensimbi ukuze yakhe uqweqwe oluvikelayo olumelana nokugqwala. Inqubo yokufaka uthayela yenzeka emazingeni okushisa aphezulu, ngokuvamile azungeze u-450°C (850°F), ukuze kuqinisekiswe ukuthi i-zinc enamathela ibhondi ngokufanelekile ensimbi.
Ngemva kokuba insimbi isifakwe uthayela, iyapholiswa futhi ihlolwe ukuze kuqinisekiswe ukuthi ukumbozwa kulinganayo futhi akunasici. I-zinc eyeqile iyasuswa, bese insimbi isilungele ukusetshenziswa okunhlobonhlobo, kusukela kwezokwakha nengqalasizinda kuya ezimotweni nasezimbonini.
Ukufingqa, inqubo ye-hot-dip galvanizing ibandakanya izinyathelo ezimbalwa ezibalulekile, okuhlanganisai-hot-dip galvanizing ngaphambi kokwelashwa, ukusetshenziswa kwamathangi okwehlisa amafutha, nokushisisa ngaphambi kokwelashwa. Lezi zinyathelo zibalulekile ukuze kuqinisekiswe ukuthi insimbi ilungiselelwa kahle inqubo yokufaka ama-galvanizing, okuholela ekugqokeni okuphezulu, okuhlala isikhathi eside okuhlinzeka ngokuvikeleka okuhle kakhulu ekugwemeni. Ngokulandela lezi zinyathelo, abakhiqizi bangaqinisekisa ukuthi imikhiqizo yabo yensimbi enezinsimbi ihlangabezana nekhwalithi ephezulu kanye nezindinganiso zokusebenza.
