1. Yog tias ua tau, nws tuaj yeem ua phosphorusized rau galvanized qhov chaw, los yog tshuaj tsuag ib txheej ntawm phosphoryly primer nyias ua ntej.
2. Los yog xuab zeb cheb rau ntawm qhov chaw du galvanized.
3. So cov kuab tshuaj (piv txwv li, zinc -zinc daj primer diluing tus neeg sawv cev) rau ntawm qhov chaw ntawm galvanized workpiece thiab galvanized yeeb nkab kom tshem tawm cov txheej tiv thaiv ntawm workpiece crude roj thiab ua kom huv si.
4. Ob chav-pob epoxy zinc daj primer: nruj me ntsis kho cov xim raws li kev faib ua feem ntawm cov xim thiab curing tus neeg sawv cev, thiab tom qab 30 feeb ntawm kev loj hlob, qhov tsim nyog viscosity yuav siv tau los tsuag. Ib qho kev tivthaiv epoxy zinc daj primer: Kev tsim kho kom zoo viscosity yog siv los tsim nws nrog txoj kev tsim kho kom raug.
