In the production process of using alkaline zinc plating brightener, sometimes the low area of the workpiece will turn black, what should I do?
In the production process of using acid zinc plating brightener, what is the reason for the blistering phenomenon of poor adhesion of the galvanized layer of the workpiece?
In the production process of using medium-phosphorus electroless nickel plating solution, the workpiece cannot be deposited with a nickel layer, which will seriously affect the production progress. So what should we do in this situation?
In the production process of using nickel plating brightener, we sometimes find that the iron ions in the plating solution are relatively high,The brightness of the produced workpiece is relatively poor, and it is prone to yellowing and whitening,And after a few days of hydrogen peroxide treatment, this phenomenon appeared again. What is the reason?
What effect does sodium hydroxide have on the plating solution in our production process using alkaline zinc plating additives?
Iron impurities are very common in baths using acid zinc plating brighteners and are the most likely to cause failure.Usually, the accumulation of iron impurities is caused by the incomplete cleaning of iron parts after pickling, the workpieces falling into the galvanizing tank and not being pulled out in time to make them too corroded, and the use of some chemical raw materials that are not pure.So how should iron impurities be removed?
