Zinc adhesion on galvanized wire surface and thickness of zinc layer

The error of construction welding net diameter should be controlled at 0.02 mm. For example, we buy wire diameter of 89 wire welding net, with a micrometer to measure the diameter, the diameter of the allowable range is 87 -91 wire. In this range is qualified welding net. Because the accuracy has been compared, but no one can control it so well in the production process. The welding net can be accurate to 0.01 mm, so the error is allowed.

In the process of composite plating, it is necessary to stir the plating solution to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. In the process of production, the acid activation solution can remove the corrosion products and oxide film on the surface of low carbon steel wire without excessive corrosion on the matrix. Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire.

The use of bundled galvanized wire with the development of industry and agriculture also expanded accordingly. Therefore, galvanized wire products in the industry, such as chemical equipment, oil processing, Marine exploration, transport, electricity, shipbuilding, metal structure, etc.), agriculture (such as sprinkler irrigation, dim room, building (such as water and gas transport, wire casing, scaffolding, house, etc.), Bridges, shipping, etc., has been widely use in recent years. Because galvanized wire goods have beautiful surface, good corrosion resistance and other characteristics, its use scale is more and more extensive.
