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.

Maintenance is indispensable in the use of galvanized wire. Large coils of galvanized silk should be coated with oil, fiber core immersion oil, oil is required to protect the fiber core is not rotten, not rust, wire moisture fiber, and from the internal lubrication wire rope. Surface coating so that all wire rope strands in the surface, are evenly coated with a layer of rust-proof lubrication grease, which for friction lifting and mineral water large mine rope, to be coated with grinding and water-resistant black oil grease. Coated with red oil with strong film and good rust resistance, it is required to have a thin oil layer, which is easy to keep clean during operation.
