Anode and cathode buffer tank

The cathode and anode buffer tank is a device used for electrochemical machining and electrochemical etching. It is a closed container, usually made of corrosion-resistant materials such as polyvinyl chloride, acrylic, etc. The cathode and anode are placed in the cathode and anode buffer tank at the same time to establish an electric field and allow the electrolyte to flow between the two electrodes. This flow can disperse bubbles and particles in the solution, thereby achieving more uniform etching. In addition, the cathode and anode buffer tank can also stabilize the potential, control the current density, adjust the electrolyte temperature, and maintain the electrolyte concentration, etc., thereby improving the processing quality and precision.

According to different usage and functions, anode and cathode buffer tanks can be divided into the following categories:

1. Cathode buffer tank: used to prevent the cathode from damage or corrosion, forming a protective film on the cathode surface so that the electrode reaction can continue. This type of tank usually uses alkaline or neutral solutions.

2. Anode buffer tank: used to prevent the anode from damage or corrosion, forming a protective film on the anode surface so that the electrode reaction can continue. This type of tank usually uses an acidic solution.

3. Neutral buffer tank: used for electrochemical reactions in a neutral environment, suitable for situations where a neutral solution is required. This type of tank usually uses a neutral solution.

4. Universal buffer tank: It is suitable for a variety of different electrochemical reactions and can be used for reactions at the cathode, anode and neutral environment. This type of tank usually uses a neutral solution.
