Hot dip galvanizing is dipped in the zinc liquid melted by heating, the production speed is fast, the coating is thick but not uniform, the market allows a low thickness of 45 microns, up to 300 microns or more. 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.
Application of hot dip galvanizing: 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, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, heating and construction such as water and gas transmission, wire bushing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.
The use of bundled galvanized wire is also expanded with the development of industry and agriculture. Therefore, galvanized wire commodities in industry (such as chemical equipment, petroleum processing, ocean exploration, metal structure, electricity delivery, shipbuilding, etc.), agriculture (such as: sprinkler irrigation, heating houses), construction (such as: water and gas transport, wire bushings, scaffolding, houses, etc.), Bridges, transportation, etc., has been widely used in recent years. Because galvanized wire products have beautiful surface, good corrosion resistance and other characteristics, its use is more and more extensive.
In the state of liquid zinc, after messy physical and chemical effects, not only a thick pure zinc layer is plated on the steel, but also a zinc-iron alloy layer is generated. This plating method not only has the characteristics of corrosion resistance of electrogalvanized wire, but also has a zinc-iron alloy layer. Also has the electric galvanizing can not be compared with the strong corrosion resistance. Therefore, this plating method is particularly suitable for a variety of strong acid, alkali mist and other strong corrosion environment.
