Dab tsi yog qhov xeb dawb ntawm galvanized txheej? Yuav tiv thaiv thiab tshem tawm li cas?

Thaum ib txheej ntawm cov dej condensed adhering rau saum npoo ntawm galvanized coatings reacts nrog oxygen, carbon dioxide, hydrogen sulfide, sulfur dioxide, chloride tebchaw, soot hais, plua plav, thiab lwm yam tshuaj gases, nws hloov mus rau hauv ib tug corrosive aqueous tov uas txuas rau lub nto ntawm zinc txheej, tsim ib qho electrolyte. Cov electrolyte no dhau los ntawm electrochemical corrosion nrog zinc txheej, uas tsis muaj tshuaj lom neeg ruaj khov, ua rau cov khoom xeb xeb hu ua "dawb xeb."
