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: Cov flaky zinc thiab txhuas txheej hauv cov txheej txheej sib tshooj ntawm cov hlau los tsim cov txheej txheem tiv thaiv thawj zaug, uas cuam tshuam cov corrosive nruab nrab xws li dej thiab oxygen los ntawm kev tiv tauj lub substrate, uas plays lub feem cuam tshuam ncaj qha cuam tshuam.
Passivation: Nyob rau hauv cov txheej txheem ntawm txheej txheej kev kho mob ntawm chromic acid nrog zinc, txhuas hmoov thiab lub hauv paus hlau Dacromet, cov zaj duab xis passivation tsim nyob rau saum npoo los ntawm cov tshuaj tiv thaiv, cov passivation zaj duab xis yog tsis prone rau 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.
