  • Hot dip galvanized steel wire surface smooth, smooth, no cracks, joints, thorns, scars and corrosion, galvanized layer uniform, strong adhesion, corrosion resistance lasting, toughness and elasticity is excellent. The tensile strength should be between 900Mpa-2200Mpa (wire diameter Φ0.2mm-Φ4.4mm). The number of torsion (Φ0.5mm) in more than 20 times, repeated bending should be more than 13 times. The thickness of galvanizing is thin, usually only 3-15 microns, bright, smooth, beautiful appearance, poor corrosion resistance, generally a few months will rust.

  • The management system of the rinsing water after the steel wire pickling should be regularly and regularly discharged after the rinsing water, and the rinsing water should be kept clean and low acid value as far as possible. The pH control is more appropriate. The concentration of plating aid should not be too high. Hot plating wire must be added ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled in the range of 50~80g/L. The addition of ammonium chloride or zinc chloride raw materials without the results of laboratory analysis shall be subject to criticism and education, and economic treatment if necessary.

  • 2, performance characteristics. Zinc coating is thick, fine crystallization, uniform and no pores, good corrosion resistance; Is pure, the zinc plating layer in acid, alkali corrosion slower, such as fog Eng effectively protect tight sand-fixation matrix, the galvanized layer formed after chromate passivation, color white, army green, beautiful and easy, have certain adornment sex, because the galvanized layer has good ductility, and therefore can be rushed, rolling, cold bending and forming and not damage the coating.
