Ubude besikhathi sokuvikela songqimba lukathayela lomqulu omkhuluucingo lukathayelaihlobene eduze nobukhulu bokunamathela.Ngokuvamile, kugesi omile lapho kuqhathaniswa nokusetshenziswa kwangaphakathi, nasezimeni ezingezinhle zemvelo, ubukhulu bongqimba lwamagalani kufanele bube phezulu kakhulu.Ngakho-ke, umthelela wemvelo kufanele ucatshangelwe lapho kukhethwa ukushuba kongqimba lwama-galvanized.Ngemuva kokwelashwa kwe-passivation kwesendlalelo esiphehliwe, ungqimba lwefilimu elidala elikhanyayo nelihle lokudlula umbala lingakhiqizwa, elingathuthukisa kakhulu ukusebenza kwalo kokuvikela.
Kunezinhlobo eziningi zekhambi elinothayela, elingahlukaniswa libe isixazululo se-cyanide plating nesixazululo se-cyanide plating.Isixazululo se-Cyanide galvanizing sinekhono elihle lokuhlakazeka kanye nekhono lokumboza, i-crystallization yokugqoka ibushelelezi futhi ilungile, ukusebenza okulula, ububanzi bokufaka isicelo, sekusetshenziswe isikhathi eside ekukhiqizeni.Kodwa-ke, ngenxa yokuthi ikhambi lokucwenga liqukethe i-cyanide enobuthi obuphezulu, igesi ephumayo enqubweni yokucwenga iyingozi empilweni yabasebenzi, futhi amanzi angcolile kufanele aphathwe ngokuqinile ngaphambi kokuba akhishwe.
I-Zinc iyinsimbi emhlophe esiliva, ephukayo ezingeni lokushisa elilingana negumbi, inyibilika ku-asidi ne-alkali, eyaziwa ngokuthi insimbi ye-amphoteric.I-zinc ehlanzekile izinzile emoyeni owomile, futhi incane emoyeni onomswakama noma emanzini aqukethe i-carbon dioxide nomoya-mpilo.Ungqimba oluncane lwefilimu oluyisisekelo lwe-zinc carbonate luzokwakhiwa phezulu, olungabambezela izinga lokugqwala kongqimba lwezinc.Ukumelana nokugqwala kongqimba olunathayela kusisombululo esinamanzi se-asidi, i-alkali ne-sodium chloride kunamandla uma kuqhathaniswa.Futhi ayimelani nokugqwala emkhathini oqukethe i-carbon dioxide ne-hydrogen sulfide kanye nasemikhathini Yasolwandle;Emazingeni okushisa aphezulu kanye nomswakama ophezulu emoyeni futhi equkethe i-organic acid emkhathini incane, ungqimba olunathayela kulula ukugqwala.
