Yakatumirwa pa 2018-05-23Iyo yekudzivirira mhedzisiro yedacromet layer pane simbi matrix inogona kupfupikiswa seinotevera:
1. Barrier effect: nekuda kwekupindirana kwe zinc uye aluminium layer, nzira yekusvika kune matrix ye corrosion media yakadai semvura uye oksijeni inogona kudzivirirwa.
2. Passivation: mu dacro process, chromic acid inopindirana ne zinc, aruminiyamu poda uye matrix simbi kuti ibudise dense passivation film, uye iyi passivation film ine good corrosion resistance.
3. Kudzivirirwa kweCathodic: iyo huru yekudzivirira ye zinc-alumina coating yakafanana neyeye zinc coating, iyo inodzivirira cathodic ye substrate.
Changzhou junhe zinc chrome dacromet coating imhando yesainzi uye tekinoroji ne zinc poda, aruminiyamu poda, chromic acid uye deionized mvura seyakanyanya kuumbwa kwemhando nyowani anticorrosive coating, pamusoro peimwe ruvara, chete sirivha nesirivha, haina kukodzera. kudiwa kwega kwega kwekusimudzira indasitiri yemotokari.Nekudaro, mavara akasiyana anogona kuwanikwa ne-post-processing kana composite coating kuvandudza kushongedza uye kuenzanirana kwezvikamu zverori.
