Custom Keychains have various shapes, such as cartoon shapes, brand shapes, and simulation models. The materials are generally copper, aluminum, rubber, plastic, etc., and the zinc alloy surface is mainly nickel-plated or rhodium-plated with anti-rust elements. The outside of the metal keychain will be electroplated, so why should we use the electroplating process for the metal keychain?
Here is the content list:
l What is the electroplating process
l How to plate metal keychains
l Material requirements for electroplated metal keychains
Electroplating is the process of plating a thin layer of other metals or alloys on the surface of the metal keychain using the principle of electrolysis. It is the process of using electrolysis to attach a layer of the metal film to the surface of the metal keychain to prevent oxidation of the metal keychain. (Such as rust), improve the wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) of the metal keychain, and enhance the beauty of the metal keychain.
The electroplating keychain requires a low-voltage high-current power supply to the electroplating tank and an electrolytic device composed of electroplating solution, the keychain (cathode) to be plated, and the anode. The composition of the electroplating solution varies depending on the plating layer, but they all contain the main salt of the metal ion that provides the metal keychain, and the complexing agent that can complex the metal ions in the main salt to form a complex, and is used to stabilize the electroplated keychain solution PH buffer, anode activator, and special additives. The electroplating process is a process in which the metal ions in the plating solution are reduced to metal atoms through the electrode reaction under the action of an external electric field, and the metal is deposited on the cathode of the metal keychain. Therefore, this is a metal electrodeposition process for metal keychains that includes liquid phase mass transfer, electrochemical reaction, and electrocrystallization. When electroplating metal keychains, the quality of anode material, electroplating solution composition, temperature, current density, power-on time, stirring intensity, precipitated impurities, power waveform, etc. will affect the quality of the coating of metal keychains and need to be controlled promptly. First of all, the electroplating solution for metal keychains has six elements: main salt, additional salt, complexing agent, buffer, anode activator, and additives.
The principle of electroplating metal keychains includes four aspects: the electroplating solution of metal keychains, the electroplating reaction of metal keychains, the principle of electrodes and reactions, and the electrodeposition process of metal keychains.
The coating of metal keychains is mostly a single metal or alloy, such as titanium palladium, zinc, cadmium, gold or brass, bronze, etc.; some metal keychains also have a coating of dispersion layer, such as nickel-silicon carbide, nickel-graphite fluoride, And so on; There are also metal keychain cladding layers, such as copper-nickel-chromium layer on steel, silver-indium layer on steel and so on. In addition to iron-based cast iron, steel, and stainless steel, the base material of electroplated metal keychains also includes non-ferrous metals
