  • Our country industry chooses the low carbon steel with good quality as raw material, and then produces the quality galvanized iron wire by drawing, galvanizing and other processes. Now the production technology of galvanized iron wire products can be divided into hot plating and electroplating two kinds of methods. No matter which one is chosen, it should be carried out in accordance with the corresponding operating specifications, so as to better ensure the production of good products. For key and important parts with tensile strength greater than 1034mpa before plating, the stress should be released at 200±10℃ for more than 1 hour and 140±10℃ before plating.

  • There are two kinds of electrochemical protection. One is to connect a piece of metal that is slightly more vivid than it. For example, ships and ships will be inlaid with zinc blocks. The second is to connect the negative terminal of the power supply, such as iron and steel river locks are often connected with the negative terminal of the power supply, through the negative terminal. Its methods include: metal cover film such as electroplating, organic coating such as paint, transformation layer such as orchid or black, new elements to change the metal structure.

  • After passivation treatment of galvanized layer, a layer of bright old and beautiful color passivation film can be generated, which can significantly improve its protective performance. There are many kinds of galvanized solution, which can be divided into cyanide plating solution and cyanide plating solution. Cyanide galvanizing solution has good dispersion and covering ability, coating crystallization is smooth and fine, simple operation, wide application range, has been used in production for a long time.
