Zinc coatings tuaj yeem tsim cov txheej txheem tiv thaiv zinc carbonate hauv qee hom av, muab kev tiv thaiv anodic rau cov yeeb nkab steel substrate. Txawm li cas los xij, qhov ua tau zoo ntawm qhov kev tiv thaiv no txawv nyob ntawm cov khoom ntawm cov av. Raws li cov ntaub ntawv cuam tshuam, pH tus nqi ntawm cov av nyob ntawm 4.3 txog 9.2. Cov kev sim ua dhau los ntawm 3 mus rau 6 xyoo siv 8 cov qauv qhia tau tias 6 ntawm lawv pom muaj qhov corrosion tsawg ntawm zinc txheej. Qhov siab tshaj plaws corrosion ntawm zinc coatings tshwm sim nyob rau hauv alkaline xau nrog siab resistivity thiab siab noo noo cov ntsiab lus.
Feem ntau hais lus, kev tshawb fawb txog kev xeb ntawm cov kav hlau galvanized hauv ntau hom av tau pom tias qhov nruab nrab corrosion ntawm zinc txheej ntawm cov kav hlau galvanized yog 1.56 txog 280 grams ib square meter ib xyoo.
