spring steel wire, we collect many information and the problems appeared during the use. Many customers said that the zinc layer on the spring steel wire surface has the scaling phenomenon.
After the research, we find some reasons of this problem and put forward some solutions.
Reason 1: the spring steel wire doesn't clean clearly before electroplated. The result is the bad combination between zinc and steel wire's surface.
The solution: when clean the spring steel wire, increase the solution concentration of electrolysis acid-washing and electrolysis alkaline wash, or increase the current of electrolysis acid-washing and electrolysis alkaline wash.
Reason 2: During the electroplating of galvanized spring steel wire, the sedimentation velocity is too fast, the surface of zinc layer is too rough and not dense.
The solution: at the time of electroplating, after the spring steel wire get into the plating bath, first to use low current density plating, then plated with high current density.
Reason 3: Use the pre-former in an improper way which will cause the scraping of zinc.
The solution: During the rope close of spring steel wire, you should choose the reasonable pre-former and decrease the zinc scraping of galvanized spring steel wire.
We believe these solutions will solute the zinc scaling phenomenon of galvanized spring steel wire. And the spring made by this material will play its full role.
