  • 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 is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.
