The oil-filled electrophoretic coating line is an efficient and environmentally friendly coating process for surface coating. One of its core equipment is the electrophoretic tank, which is an important part of the oil-filled electrophoretic coating line and is mainly used for cathodic electrophoretic coating of the workpiece surface.

The electrophoretic tank is usually composed of a tank body, tank liquid, power supply system, stirring system and other parts. The tank body is usually made of stainless steel or corrosion-resistant plastic to ensure its stability and durability during the coating process. The tank liquid is the key to electrophoretic coating. It is usually composed of a conductive liquid containing resin, pigment, additives and other ingredients. The coating is attached to the surface of the workpiece through the electrophoretic electric field. The power supply system provides an electric field so that the coating can be evenly deposited on the surface of the workpiece. The stirring system plays a role in stirring the tank liquid and maintaining the uniformity of the coating.

The working principle of the oil-filled electrophoretic coating line is to place the workpiece in the electrophoretic tank. Under the action of the applied electric field, the workpiece surface has a relatively strong affinity for the paint, and the paint will evenly adhere to the workpiece surface under the action of the electric field. This can achieve uniform and dense coating on the workpiece surface, improving the coating quality and efficiency.

The oil-filled electrophoretic coating line has many advantages. First, electrophoretic coating is a more environmentally friendly coating method. Since the paint is mainly attached to the surface of the workpiece, most of the paint can be fully utilized, reducing the waste of paint. Secondly, electrophoretic coating has high coating uniformity and adhesion, which can ensure the quality and durability of the workpiece surface. In addition, the oil-filled electrophoretic coating line can also realize automated production, improve production efficiency, and reduce labor costs.

In general, the electrophoretic tank of the oil-filled electrophoretic coating line is one of its key equipment, which plays a vital role in the coating quality a
