Power supply type: Silicon controlled rectifier

Application Industry: Metal materials anode and cathode electrophoretic coating.

•  The DC output pole is installed with the filter reactor and capacitor according to the electrophoresis process to make the ripple wave system indicator reach the coating process requirement. The low ripple voltage can enable dense coat, uniform coat thickness, smooth surface and strong adhesion on the surface of the metals.
• The multi-section voltage ascending mode can be used according to the electrophoresis process. The voltage and time of each section can be set.
• The PLC PID high-speed adjustment is used. The double-channel and double-digital trigger control mode is used. The PLC+ touch screen control is used. The voltage, current, voltage division and section time can be set. The remote upper device can be controlled in linked manner to enable automatic electrophoresis.
• The PROFIBUS, MODBUS and CC-LINK bus network and optic fiber industrial Ethernet network can be connected according to the customer’s requirements. The analog signal control mode such as 4-20mA, 0-5V and 0-10V can be connected.
• The perfect protection functions such as phase Failure, over-voltage, over-current, over-heat and short circuit are provided.

Electrophoresis process is divided into anode electrophoresis and cathode electrophoresis. If the coating particles are negatively charged, the workpiece is anode, and the coating particles are deposited into a film on the workpiece under the action of electric field force, which is called anodic electrophoresis; On the contrary, if the coating particles are positively charged and the workpiece is cathode, the coating particles are deposited on the workpiece into a film called cathode electrophoresis.

Anodic electrophoresis is characterized by: cheap raw materials (generally 50% cheaper than cathodic electrophoresis); Simple equipment, less investment (generally 30% cheaper than cathodic electrophoresis); Low technical requirements; The corrosion resistance of the coating is worse than that of cathodic electrophoresis (about 1/4 of the cathodic electrophoresis life).

The reasons for the high corrosion resistance of cathodic electrophoretic coating are as follows: the workpiece is cathode, no anodic dissolution occurs, and the workpiece surface and phosphating film are not damaged; Electrophoretic paint (usually nitrogenous resin) has a protective effect on metals, and the paint used is of high cost and quality.
