Metallized mirrors require a low-voltage, high-current power supply to the plating bath, and an electrolytic installation consisting of a bath, a part to be plated (cathode), and an anode. Wherein the makeup mirror liquid composition varies depending on the plating layer, but contains a main salt for providing metal ions, a complexing agent capable of complexing the metal ions in the main salt, a buffer for stabilizing the pH of the solution, an anode activator And special additives.

     Electroplating metal mirror process is the metal ions in the bath under the action of the external electric field, the electrode response to restore the metal atoms, and in the cathode to stop the process of metal deposition. Thus, it is a metal electrodeposition process involving steps such as liquid phase mass transfer, electrochemical reactions, and electrocrystallization.

     In the electroplating brand of mirror plating tank, through the liquidation and special pretreatment to be plated as cathode, made of plated metal anode, poles, respectively, with the DC power supply anode and cathode connection. The plating solution is composed of an aqueous solution containing a plating metal compound, a conductive salt, a buffer, a pH adjusting agent and an additive. After power, the metal ions in the plating solution, the role of the potential difference in the cathode to move to the composition of the coating. The metal of the anode forms a metal ion into the plating bath to maintain the concentration of the plated metal ions.

     In some cases, such as chrome, is the use of lead, lead antimony alloy made of insoluble anode, it only plays the role of transmission of electrons, conduction current. Chromium ion concentration in the electrolyte, to rely on regularly to the bath to participate in chromium compounds to maintain. Electroplating high-grade mirror, the quality of the anode data, the composition of the bath, temperature, current density, power time, stirring intensity, precipitated impurities, power waveforms will affect the coating quality, timely stop control needs.

     First of all, electroplating of the mirror solution has six elements: the main salt, additional salt, complexing agent, buffer, anode activator and additives. Electroplating principle includes four aspects: electroplating solution, electroplating reaction, the principle of electrode and response, the metal stacking process. Electroplating metal mirror when the reaction of the electrochemical response: The following figure is the plating installation diagram, was plated parts for the cathode, and the DC power supply is connected to the anode, metal anode and DC power cathode, anode and cathode are immersed in the bath in.

   When a certain potential is applied between the cathode and the cathode, the metal ions Mn + diffusing from the interior of the plating solution to the interface between the electrode and the plating bath are taken to recover n electrons from the cathode and recover the metal M from the cathode. On the other hand, the anode reacts with the cathode completely opposite, that is, the dissolution of the metal M at the anode interface, and releases n electrons to generate metal ions Mn +.
