Product use
It has applications in electroplating and electrolysis industries, and can also be used to make cables.
Zinc sulfate heptahydrate is widely used in galvanizing solutions. During electroplating, the biggest advantage of zinc sulfate heptahydrate solution galvanizing is that the current efficiency is as high as 100% and the deposition rate is fast. This is unmatched by other galvanizing processes.
The traditional sulphate zinc plating process is only suitable for electroplating of pipes and wires with simple geometric shapes due to the lack of fine crystallization of the coating and poor dispersion ability and deep crossing ability. In the zinc sulfate electroplating process of zinc-iron alloy, except for the main salt zinc sulfate, the other ingredients are discarded. An appropriate amount of iron salt is added to the new process formula to make the original single metal coating form a zinc-iron alloy coating. The reorganization of the process not only carried forward the advantages of high current efficiency and fast deposition rate of the original process, but also greatly improved the dispersion ability and deep plating ability. In the past, complex parts could not be plated, but now simple and complex parts can be plated, and the protective performance It is 3 to 5 times higher than that of single metal.
Production practice has proved that the continuous electrogalvanization of wires and pipes with zinc sulfate bath will have finer, brighter and faster deposition rate than the original coating. Meet the requirement of coating thickness within 2~3min
