Hot dip galvanizing is in the heated melting zinc liquid dip plating, production speed, thick but uneven coating, the market allows a low thickness of 45 microns, up to 300 microns. Dark color, consumption of zinc metal, and matrix metal formation of infiltration layer, good corrosion resistance, hot dip galvanizing in outdoor environment can be maintained for decades.
Hot dip galvanizing application: Because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for steel parts in harsh working environment. 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 irrigation, greenhouse and construction such as water and gas transmission, wire casing, scaffolding, bridge, highway guardrail and other aspects, has been widely used.
In order to bundle the electrogalvanized wire on the surface of the deposited layer to remove the surface film layer, surface inclusions and other defects can be found and treated by conventional technology; Excess foam is caused by soap and surfactant saponable fats brought into the tank. Moderate rates of foam formation may be harmless. Small homogeneous particles with large denier in the tank can stabilize the foam layer. Coated with activated carbon to remove surfactant. Or by filtering to make the foam less stable, this is an effective measure; Other measures should also be taken to reduce the amount of surfactant brought in. The speed of electroplating can be significantly reduced by the addition of organic matter. Although the chemical formulation is conducive to high deposition rate, but the organic matter with the coating thickness can not meet the requirements, so activated carbon can be used to treat the tank liquid.
