Ikhoyili ehlanganiswe ngombala inesisindo esilula, ukubukeka okuhle kanye nokumelana nokugqwala okuhle.Isetshenziswa kakhulu embonini yokukhangisa, embonini yezokwakha, embonini yemishini yasendlini, embonini yezinto zikagesi, imboni yefenisha kanye nemboni yezokuthutha.Ngokwendawo ehlukene yokusetshenziswa, ihlukaniswe yaba izinhlobo ezintathu: i-hot-dip galvanized substrate, i-hot-dip aluminium-zinc substrate kanye ne-electro-galvanized substrate.Ngenxa yezindawo ezihlukene, impilo yesevisi ihluke kakhulu.Namuhla, sizobheka ngokucophelela izici ezithinta impilo yesevisi yamapuleti afakwe umbala?
Ngokwesisekelo sokucwebezelisa, amakhoyili ahlanganiswe ngombala aphathwa ngokuhlanzwa kwendawo kanye nefilimu yokuguqula amakhemikhali, bese embozwa nge-primer (egxile ekunamatheleni nasekulweni nokugqwala) kanye ne-topcoat (egxile ekuphikisweni kwesimo sezulu kanye nokuhlobisa), kanye nezingubo ezimbili eziminyene zemvelo. .Umgoqo ovikelayo uvimbela ngokuphumelelayo ukungena kwama-molecule amanzi kanye nemidiya ebolayo, futhi unamandla okumelana nokubhujiswa nokubola kokukhanya kwemvelo njengemisebe ye-ultraviolet.Ubukhulu be-coating kufanele bufinyelele ubukhulu befilimu obucacisiwe ukuze kutholwe ifilimu elivikelayo elicinene, kuncishiswe ukungena kwamanzi nomoya-mpilo, futhi kuvimbele ukugqwala kwento enamathelayo.Ngohlobo olufanayo lopende, ukushuba kopende kuyisici esiyinhloko esithinta ukugqwala.
Lapho ubukhulu be-coating bungaphansi kuka-10μm, ukumelana nokugqwala ngokuvamile akukwazi ukufinyelela ku-500h;esikhawulweni sika-10～20μm, ngemva komjikelezo ofanayo wokuhlola, ukwandisa ukujiya koqweqwe lwawo kunomphumela ophawulekayo ekunciphiseni izinga lokugqwala kwengubo;phakathi kuka-20～26μm Ngesikhathi esifanayo, izinga lokugqwala le-coating likhuphuka ngokuqina, futhi ukuguqulwa akubonakali;futhi ubunzima bokulawula benqubo yokumboza buzokhula ngokukhula kobukhulu.I-coating engaphezulu kuka-26μm ijwayele ukuvela ezimeni ezingezinhle njengokuqina kwemiphetho;kungabonakala ekuhloleni Okubanzi kwezindleko nokusebenza, i-20μm iyinani eliphansi lokuzuza ukumelana nokugqwala okuhle nokusemoyeni.
