Yakatumirwa pa 2018-08-091. Chigadziko chimwe nechimwe chezinc uye aluminium mu zinc aluminium coating iri mu passive state , nepo galvanized layer ine passivation layer ye 0.05 ~ 0.2μm pamucheto wekunze;
2. Iyo zinc uye aluminium mapepa mu zinc aluminium coating inoita basa rakazara rekupira anode kudzivirira, nepo zinc coating ichaonekwa tsvina ye zinc mushure mekunge passivation layer yaparadzwa.
3. Inorganic acid chikamu mumucheka uye chifukidzo chinogona kuchengetedza matrix yesimbi panguva imwe chete pakudzivirira zinc uye aluminium , nepo zinc plating isingaiti.
4. Iyo zinc coating passivation layer pa 70 ~ 100 ℃ madhigirii centigrade, crystallization yemvura yakatanga kubuda, zvichiita kuti passivation layer kuputika, inokanganisa kusaora kwekudzivirira kwe zinc coating, uye zinc aluminium coating pa 260 degrees kana yakakwirira tembiricha sintering, saka. pachiitiko chakadaro.
