Optimization of sulphate galvanizing
The biggest advantage of sulphate galvanizing is that the current efficiency is up to 100% and the deposition rate is fast, which is unmatched by other galvanizing processes. Because the plating crystal is not detailed enough, the dispersing ability and the deep plating ability are poor, so it is only suitable for electroplating of pipes and wires with simple geometric shapes. The sulphate electroplating zinc-iron alloy process optimizes the traditional sulphate galvanizing process, leaving only the main salt zinc sulphate, and the remaining components are discarded. In the composition of the new process, an appropriate amount of iron salt is added to form a zinc-iron alloy coating on the original single metal coating. The reorganization of the process not only carries forward the advantages of high current efficiency and fast deposition rate of the original process, but also greatly improves the dispersing ability and deep plating ability. In the past, complicated parts could not be plated, and now simple and complicated parts can be plated, and the protective performance It is 3 to 5 times higher than single metal. The production practice proves that for continuous plating of wire and pipe, the plated grain is more refined and brighter than the original, and the deposition rate is fast. The thickness of the coating reached the requirement within 2 to 3 minutes.
