I-rol enkulul ucingo lukathayelaisetshenziswa kabanzi ekusebenzeni.Insimbi yensimbi nayo inokulimala okuthile, ukugqwala kalula nokugqwala.Ngakho-ke, indlela yama-galvanized ingasetshenziswa ngokujwayelekile ukuvimbela ukugqwala kwemikhiqizo.Ngaphezu kwale ndlela, izindlela zokwelapha zensimbi ezivame ukusetshenziswa kanye nokwelashwa kwe-phosphating, ukwelashwa kwe-oxidation, njll. Ukwelashwa kwe-Metal phosphating: imikhiqizo yensimbi nensimbi kumafutha, ukususwa kokugqwala, ekubunjweni okukhethekile kokucwiliswa kwesisombululo se-asidi, kungakha ungqimba lwe-insoluble. ifilimu ene-asidi endaweni yensimbi, le nqubo ibizwa ngokuthi ukwelashwa kwe-phosphating.
Umqulu omkhuluucingo lukathayelaIfilimu ye-phosphating inombala ompunga omnyama kuya kumnyama omnyama, ubukhulu ngokuvamile bungu-5-20μm, emkhathini unokumelana okuhle nokugqwala.I-Membrane iyisakhiwo se-microporous, njengomthamo we-adsorption kapende uqinile, njengokusetshenziswa njengongqimba olungezansi lopende, ukumelana nokugqwala kungathuthukiswa.Ukwelashwa kwe-metal oxidation: imikhiqizo yensimbi yengezwa engxube yesisombululo se-NaOH ne-NaNO2, ukwelashwa kokushisisa, ubuso bayo bungenza ungqimba lokuqina okungaba ngu-0.5-1.5μm yefilimu ye-blue oxide, ukuze kufinyelelwe inhloso yokuvimbela ukugqwala kwensimbi, le nqubo ibizwa ngokuthi ukwelashwa okuluhlaza okwesibhakabhaka, okubizwa ngokuthi okwesibhakabhaka.
Le filimu ye-oxide inokunwebeka okukhulu kanye nokuthambisa futhi ayithinti ukunemba kwezingxenye.Ngakho-ke, amathuluzi anembayo nezingxenye zensimbi yokubona, insimbi yasentwasahlobo, ishidi lensimbi elincanyana, intambo yensimbi encane kanye nokunye okuvame ukusetshenziswa okuluhlaza okwesibhakabhaka.Intambo enkulu eyakhiwe ngothayela evame ukusetshenziswa ekwelapheni okuwuthayela, ilingana nokwenza ungqimba oluvikelayo phezu kocingo, oluvame ukusetshenziswa.ukushisa okushisayo, isifutho esishisayo, i-vacuum plating nezinye izindlela, izindlela ezahlukene zinezici ezihambisanayo.
