Silver Electroplating Process Introduced

In the past, the use of non-bright Silver Electroplating process is poor appearance, low corrosion resistance, especially anti-sulfur anti-discoloration ability is poor, in order to light, usually using chemical polishing or copper brush brush and then dip silver, so that both waste of electricity and time , But also pollute the environment.

In order to solve the above problems, the domestic Silver Electroplating generally used two methods, one is the use of antimony potassium tartrate with organic additives (mostly sulfur compounds) to obtain a bright silver-plated layer, this method due to the impact of antimony and sulfur, , Brittle, weldability is not ideal. The other is the use of cyanide bright silver, this method uses a sulfur-free organic brightener and the right amount of antimony potassium tartrate with the use of the whole bright silver layer, to solve the coating easy to change color, brittle, The problem is not ideal, while reducing the consumption of raw materials. However, this method because of the need for more organic complexes, making the factors affecting the plating increased, but also increased the process. In order to seek a time-saving and provincial method of raw materials, based on the original process on the basis of the reform, recommend an impact Silver Electroplating process, that is, at higher current density, in just a few seconds to complete the silver, silver Thin and uniform light, the plating solution is simple, do not need other organic ingredients, the process once completed, the time is short, high production efficiency.

Silver Electroplating to save raw materials (silver is only the original cyanide bright silver about 4%).

Silver Electroplating oil → hot water wash → cold water washing → chemical rust → washing → cyanide copper plating → washing → acid bright copper plating → washing → bright nickel plating → washing → impact Silver Electroplating → deionized water (or distilled water) wash → passivation → dip 400 organic film → drying → dip paint protective film → drying → inspection.
