Galvanized hlau
Galvanized steel muaj zoo heev liab qab corrosion kuj vim nws siab - zoo zinc txheej thiab passivation zaj duab xis yam ntxwv. Nyob rau hauv chav tsev kub, zinc tseem tsis hloov pauv hauv qhov chaw qhuav. Nyob rau hauv qhov chaw ntub dej, cov ntshav ntawm cov zinc tsim cov zinc carbonate tuab heev, uas tuaj yeem tiv thaiv sab hauv ntawm zinc los ntawm corrosion. Vim muaj cov khoom ntawm zinc, zinc yog plated rau saum npoo ntawm cov hlau phaj los tiv thaiv corrosion. Xinyu galvanized ntawv yog dav siv hauv cov cua txias, tub yees, thiab HVAC kev lag luam. Zinc flake zinc txheej ntawm cov ntawv tsim galvanized tuaj yeem kho raws li cov neeg siv khoom xav tau, tsis muaj cov pa phem ib puag ncig, thiab cov yeeb yaj kiab passivation kuj tsis muaj cov pa phem ib puag ncig.

Spangle
Lub "spangle" yog ib hom ntawm qhov chaw morphology pom ntawm kub -dip galvanized (ntshiab zinc-coated) steel coils. Thaum cov hlau sawb hla dhau lub lauj kaub zinc, nws qhov chaw yuav coated nrog kua zinc. Raws li zinc txheej ib txwm solidifies, zinc nplej nucleate thiab loj hlob, ua dab tsi hu ua "spangle."
Lub npe "spangle" los ntawm qhov tseeb tias cov zinc ua tiav cov khoom siv ua kom pom cov paj ntoo zoo li cov qauv, uas yog qhov tseeb thiab piav qhia.
