Hot dip galvaningkuyindlela esetshenziswa kabanzi yokuvikela insimbi ekugcekeni. Le nqubo ifaka izinyathelo ezimbalwa ezibalulekile, kufaka phakathi ukwelashwa kwangaphambi, okubaluleke kakhulu ekuqinisekiseni ikhwalithi nokuqina kwenhlanganisela ye-galvanized. Isici esibalulekile sokwelashwa kwangaphambili ukusetshenziswa kwamathangi ahlekisayo kanye nokushisa ukuze uyilungiselele inqubo ye-galvaning.
Isinyathelo sokuqala kwinqubo eshisayo ye-galvaningukwehlisa, okubandakanya ukuhlanza insimbi ukuze kususwe noma yikuphi ukungcola okungaphazamisa inqubo ye-galvaning. Lokhu kuvame ukwenziwa ithangi elihlanzayo, lapho insimbi icwiliswe esixazululweni esishisayo se-alkali ukususa amafutha, uwoyela noma ezinye izinsalela eziphilayo ezivela ebusweni. Ithangi elihlanza yingxenye ebalulekile yeinqubo yangaphambi kokwelashwaNjengoba iqinisekisa ukuthi insimbi ihlanzwa kahle ngaphambi kokuba igayiselelwe.
Lapho insimbi ihlanzwa ethangini elihlanzayo, lingabaKufudumele. Lesi sinyathelo sibandakanya ukufudumeza insimbi ukususa noma yimuphi umswakama osele futhi ulungiselele indawo yenqubo ye-galvaning. Ukushisa insimbi kubalulekile njengoba kusiza ekuqinisekiseni ukuthi ukuhlanganiswa okunama-galvanized kunamathela ebusweni ngendlela efanele, okuholela ekuqedeni okuhlala isikhathi eside futhi okuhlala isikhathi eside.
Lapho izinyathelo zangaphambi kokwelashwa ziqediwe, insimbi isilungelehot-cxuse galvaninginqubo. Lokhu kufaka phakathi ukucwilisa insimbi kubhavu we-zilten zinc, okufakwa ngensimbi ngensimbi ukuze kwakhiwe ukunamathela okuvikela okungazweli kakhulu. Inqubo ye-Galvaning yenzeka emazingeni okushisa aphezulu, imvamisa cishe ngo-450 ° C (850 ° F), ukuqinisekisa ukuthi ama-zinc coating bond kahle ngensimbi.
Ngemuva kwensimbi ku-galvanized, kupholile futhi kuhlolwe ukuthi kuqinisekiswe ukuthi ukuhlanganiswa kungenasici nanoma yiziphi izici. I-zinc eyeqile isuswa, futhi insimbi isilungele izinhlelo eziningi zohlelo, kusuka ekwakheni nasengqalasizinda kuya ezimotweni kanye nemishini yezimboni.
Ukufingqa, inqubo eshisayo ye-galvaning ifaka izinyathelo ezimbalwa ezibalulekile, kufaka phakathiI-galvanizing yangaphambi kokwelashwa, ukusetshenziswa kwamathangi okuhlanza, nokushisa kwangaphambi kokwelashwa. Lezi zinyathelo zibalulekile ukuze uqinisekise ukuthi le nsimbi ilungiselelwe kahle inqubo ye-galvaning, okuholele ekutholeni okuphezulu, okuhlala isikhathi eside okunikeza isivikelo esihle kakhulu ekubhujisweni. Ngokulandela lezi zinyathelo, abakhiqizi bangaqinisekisa ukuthi imikhiqizo yabo yensimbi ye-galvanized ihlangabezana namazinga aphezulu kakhulu okusebenza kanye nokusebenza.
