Txoj kev tiv thaiv thiab tshem tawm cov xeb dawb ntawm galvanized txheej

Thaum ib txheej ntawm cov dej condensed adhering rau saum npoo ntawm galvanized txheej reacts nrog oxygen, carbon dioxide, hydrogen sulfide, sulfur dioxide, chemical compounds, soot particles, plua plav, thiab lwm yam chemical gases, nws transforms mus rau hauv ib tug corrosive aqueous tov uas txuas rau. qhov saum npoo ntawm zinc txheej, tsim ib qho electrolyte. Qhov no electrolyte tom qab ntawd dhau electrochemical corrosion nrog zinc txheej, uas tsis muaj tshuaj lom neeg ruaj khov, uas ua rau cov khoom siv hmoov corrosion hu ua "dawb xeb".
