welding performance. Silver coating was first used in decoration. In the electronics industry, communications and instrumentation industry, the use of silver plating to reduce the resistance of metal parts, improve the welding performance of metal. The metal mirrors in the searchlights and other reflectors also need to be plated with silver. Jin Yuan Kang silver can prevent corrosion products, increase conductivity, light and beautiful appearance. Widely used in electrical appliances, instruments, meters and lighting equipment manufacturing industry. Such as copper or copper alloy plating, must first after degreasing derusting solution; pre plating thin silver or immersed by mercuric chloride prepared in the treatment of mercury, which was coated on the surface of workpiece is a layer of mercury film; then parts as cathode, silver plate as the anode and electrolyte of Potassium Silver Cyanide immersion by silver nitrate and potassium cyanide compounded in electroplating. Electrical equipment, instruments and other industries also use cyanide free silver plating. Thiosulfate, sulfite, thiocyanate, ferrocyanide, etc.. In order to prevent discoloration of the silver coating, usually after plating treatment, mainly immersion, chemical and electrochemical passivation, precious metals or precious Metal Plating
or coating layer, etc..
As the silver coating is a bright reflection, the heat generated by the infrared radiation can be a good reflection back to achieve better insulation effect. So the silver plated hot water pot has a better role of heat preservation.
