After the silver, the historic precious metal an application, content in the crust is small, accounting for only 0.07ppm, sterling silver is a beautiful silvery-white metal, jewelry and utensils that have good reflectivity, polished It can achieve high brightness and is widely used in jewelry and home decoration. The plating of some silver on some metal surfaces can also achieve the decorative effect of pure silver. The appearance is bright and detailed, and it is wear-resistant, corrosion-resistant, and has strong discoloration resistance, so it has a wide range of applications. The previously used non-bright silver plating process has poor appearance, low anti-corrosion force, and particularly poor ability to resist sulfur and discoloration. In order to emit light, chemical polishing or copper brushing and reimmersion silver are usually used, which wastes electricity and time. And pollute the environment. In order to solve the above problems, two methods are commonly used in the country. One is to use a bismuth potassium tartrate with organic additives (mostly sulphur compounds) to obtain a bright silver plating layer. This method makes the coating easily discolored and brittle due to the effects of antimony and sulfur. Large, solderability is not ideal. The other is the use of cyanide bright silver plating, this method uses a non-sulfur organic brightener and the appropriate amount of potassium antimony tartrate in combination to obtain a bright silver layer, to solve the coating is easy to change color, brittle, can be welded The problem of unsatisfactory sexuality, while reducing the consumption of raw materials . However, due to the large number of organic complexes required in this method, the number of factors influencing electroplating increases, and the number of processes increases. In order to find a way to save time and labor and materials, a reform was made on the basis of the original process, and an impact silver plating process was recommended. That is, at a higher current density, silver plating and silver layers were completed in a few seconds. Thin and uniform light, the composition of the electroplating solution is simple, no other organic ingredients are needed, the process is completed once, the time is short, and the production efficiency is high.
