Hauv qee cov tshuaj passivation formulations, cov kua qaub xws li nitric acid, sulfuric acid, phosphoric acid, thiab acetic acid ntxiv. Cov txiaj ntsig muaj xws li: ua kom yooj yim rau kev sib cais ntawm chromates, ua kom lub cev muaj zog ntawm cov yeeb yaj kiab passivation thiab qhov kev sib cais ntawm zinc, ua kom muaj hydrogen tiam, ua kom lub cev muaj zog ntawm cov yeeb yaj kiab passivation, thiab ua kom lub ntsej muag zoo rau cov yeeb yaj kiab passivation.
Qhov tsis zoo yog: txo cov tuab zoo ntawm cov zinc txheej ntshiab, roughening txheej galvanized zinc txheej, thiab ua rau cov tsos ntawm daj thiab liab me ntsis. Qhov sib ntxiv ntawm cov kua qaub kuj tsis zoo rau kev kho cov roj khib nyiab, dej khib nyiab, thiab cov khoom khib nyiab.
