The difference is that hot dip galvanizing is dipped in zinc solution melted by heating, the production speed is fast, and the coating is thick but not uniform. The color is dark, the consumption of zinc metal is more, the infiltration layer is formed with the base metal, the corrosion resistance is good, and the hot dip galvanizing can be maintained for decades in the outdoor environment. Cold galvanizing (galvanizing) is in the plating tank through the current one-way to gradually plating zinc on the metal surface, the production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 microns, the appearance is bright, poor corrosion resistance, generally a few months will rust.
Compared with electrogalvanizing, hot-dip galvanizing has lower production cost and less impact on the environment than electroplating. Because the resulting coating is thicker, hot-dip galvanizing has better protective properties than electric galvanizing, so it is an important protective coating for steel parts used in harsh working environments. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, ocean exploration, metal structure, power transmission, shipbuilding and other industries.
In the field of agriculture such as pesticide irrigation, heating and construction such as water and gas transmission, wire bushing, scaffolding, Bridges, highway guardrail, etc., has been widely used in recent years. Because the amount of zinc on the hot-dip galvanized wire is thicker, hot-dip galvanized has better protective properties than electric galvanized, so it is an important protective coating for steel parts used in harsh working environments.
