Tshaj tawm rau 2018-08-13Lub hauv paus ntsiab lus ntawm Dacromet deg kev kho mob yog cais kev sib cuam tshuam ntawm dej, oxygen thiab hlau kom tau txais cov nyhuv antiseptic muaj zog.Lub hauv paus ntsiab lus yog kev koom tes ntawm peb txoj kev tiv thaiv.
Cov nyhuv Barrier: Lub flaky zinc thiab aluminium txheej nyob rau hauv cov txheej txheej sib tshooj ntawm cov hlau los tsim thawj txheej tiv thaiv, uas cuam tshuam qhov nruab nrab corrosive xws li dej thiab oxygen los ntawm kev sib cuag lub substrate, uas plays qhov ncaj qha cais cov nyhuv.
Passivation: Nyob rau hauv cov txheej txheem ntawm txheej kev kho mob ntawm chromic acid nrog zinc, txhuas hmoov thiab lub hauv paus hlau Dacromet, passivation zaj duab xis tsim nyob rau saum npoo los ntawm cov tshuaj tiv thaiv, cov passivation zaj duab xis yog tsis nquag mus corrosion, thiab kuj ua raws li ib tug barrier.Qhov kev txiav txim ntawm corrosive media, ua ke nrog cov nyhuv barrier, muab kev tiv thaiv ob txheej uas txhawb kev cuam tshuam ntawm kev sib cais ntawm lub cev.
Kev tiv thaiv Cathodic: Qhov no yog qhov tseem ceeb tshaj plaws tiv thaiv cov nyhuv.Raws li lub hauv paus ntsiab lus ntawm galvanized txheej, cathodic tiv thaiv yog siv rau lub substrate ntawm cov tshuaj txheej los ntawm kev txi cov anode.
Ntawm qhov tod tes, peb hom kev tiv thaiv no tiv thaiv cov nyhuv corrosive ntawm corrosive nruab nrab ntawm cov hlau.Ntawm qhov tod tes, lub substrate yog hluav taws xob corroded, thiab nws tsis yog xav tsis thoob tias muaj ob peb zaug kev tiv thaiv ntawm cov tsoos electroplating zinc.
