Principle and use of mobile cathode electroplating tank
1. Principle of mobile cathode electroplating tank
Mobile cathode electroplating tank is a commonly used electroplating equipment, which is a technology that covers metal or alloy on conductive materials based on the principle of electrolysis. The equipment consists of a tank, a mobile cathode, a wave-avoiding plate, a power supply and a regulator. The mobile cathode is responsible for movement, while the electrolyte circulates in the tank, so that the electroplating grows directionally on the workpiece. The power supply and regulator are used to control the voltage and current density to ensure the thickness and uniformity of the electroplating layer.
2. Choose the right electroplating solution and electrode material
It is very important to choose the right electroplating solution and electrode material. First of all, the selection of electroplating solution should be determined according to the requirements of the coating, the coating material and the material, shape, size and surface state of the workpiece. Usually, the electroplating solution includes acidic electroplating solution, alkaline electroplating solution and salt bath electroplating solution. Secondly, the selection of electrode material should be determined according to the properties of the plating solution. In general, the electrode material should have good conductivity, corrosion resistance and wear resistance.
3. Precautions for use
1) Before starting the equipment, it is necessary to check whether all parts of the equipment are intact, and fully clean and pre-treat the electrodes and workpieces.
2)Before adding the electrolyte, it is necessary to check whether its composition, concentration, temperature and other parameters meet the requirements and circulate in the tank.
3)During the working process, attention should be paid to maintaining the composition, concentration and temperature of the electrolyte parameters to avoid affecting the uniformity and quality of the electroplating layer.
4)After taking out the electroplated parts, they must be cleaned and polished to ensure the surface finish and quality of the products.
4. Solutions to common problems
1)Electrode material corrosion: electrode materials suitable for the electroplating solution should be selected, and electrodes should be replaced regularly.
2)Uneven thickness of the electroplating layer: the distance and angle between the electrode and the workpiece should be checked, and parameters such as voltage and current density should be adjusted.
3)Electrolyte contamination: the tank should be cleaned and the electrolyte should be filtered regularly to avoid the influence of impurities on the quality of electroplating.
In short, the mobile cathode electroplating tank is an important electroplating equipment. Proper use and maintenance can ensure the quality of electroplating and production efficiency.
