  • 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 iron is clean and clean, and then solvent treatment, after drying immersed in zinc liquid, iron and molten zinc reaction to produce an alloyed zinc layer, the process is: degreasing – washing – pickling – assisted plating – drying – hot dip galvanizing – separation – cooling passivation. The thickness of the alloy layer of hot plating wire mainly depends on the chemical composition of the steel silicon content, the size of the steel cross-sectional area, the roughness of the steel surface, the temperature of the zinc pot, the time of dipping zinc, cooling speed, cold rolling deformation, etc.

  • Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Electroplating solution with solid particles or excessive foreign metal impurities, will lead to such problems. Solution: If the large roll galvanized wire to the above coating is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.
