Tshaj tawm rau 23-05-2018Cov nyhuv tiv thaiv ntawm dacromet txheej ntawm steel matrix tuaj yeem ua tiav raws li hauv qab no:
1. Cov nyhuv thaiv: vim qhov sib tshooj ntawm zinc thiab txhuas txheej, cov txheej txheem ntawm kev ncav cuag lub matrix ntawm corrosion media xws li dej thiab oxygen tuaj yeem tiv thaiv.
2. Passivation: nyob rau hauv cov txheej txheem dacro, chromic acid reacts nrog zinc, txhuas hmoov thiab matrix hlau los ua tuab passivation zaj duab xis, thiab zaj duab xis passivation no muaj corrosion kuj zoo.
3. Cathodic tiv thaiv: lub ntsiab tiv thaiv cov nyhuv ntawm zinc-alumina txheej yog tib yam li cov zinc txheej, uas yog cathodic tiv thaiv substrate.
Changzhou junhe zinc chrome dacromet txheej yog ib hom kev tshawb fawb thiab thev naus laus zis los ntawm zinc hmoov, txhuas hmoov, chromic acid thiab deionized dej raws li lub ntsiab muaj pes tsawg leeg ntawm hom tshiab anticorrosive txheej, nto ntawm ib qho xim, tsuas yog nyiaj thiab nyiaj, tsis haum rau tus kheej xav tau ntawm kev tsim kho tsheb kev lag luam.Txawm li cas los xij, cov xim sib txawv tuaj yeem tau txais los ntawm kev ua haujlwm tom qab lossis cov txheej txheem sib xyaw kom txhim kho kev kho kom zoo nkauj thiab kev sib txuam ntawm cov tsheb thauj khoom.
