Recently heard that the processing of the specific heat of the production of steel galvanized in the price and the effect above all have advantages, so how much do you want to pay for the processing of the Rockwell? How does the rust-proof effect compare with the hot dip galvanizing?
From the time of smoke, the Dacromet salt spray experiment time is long, but the test in neutral environment, from outdoor atmosphere environment, hot dip galvanized corrosion resistance is better;
In addition, the hot dip galvanized coating thick, the appearance is coarse, but the adhesion is good, surface treatment can resist high temperature; The Rockwell coating is thin and shiny, but the surface treatment cannot resist high temperature.
Dacromet is Dacromet transliteration and abbreviation, abbreviation Dacromet, duck rust, Dicron. Domestic named zinc-chromium coating, is a zinc powder, aluminum powder, chromic acid and deionized water as the main component of the new anti-corrosion coating.
Process: Organic solvent oil removal--mechanical polishing--spraying--baking--two times spraying--baking--drying
Hot-dip Galvanizing (galvanizing) is also called hot-dip zinc and hot-dip galvanizing: It is an effective metal anti-corrosion way, mainly used in various industries of metal structural facilities. is the rust after the steel immersed in 500 ℃ molten zinc, so that the surface of steel members adhere to the zinc layer, so as to prevent corrosion.
Process: finished pickling-washing-add-support bath-drying-hanging-plating-cooling-pharmaceutical-cleaning-polishing-hot-dip galvanizing finished.
