The main factors causing the bath temperature rise of electrophoretic paint are:

1, in the process of electrophoretic coating, part of the electric energy of the electrophoretic power supply is converted into heat energy

2, circulating mixing system ( mainly circulating pump operation ) due to mechanical friction and heat energy is absorbed by electrophoretic paint;

3, the change of environmental temperature caused by tank liquid temperature rise. Influence of too high temperature of electrophoretic bath paint; If the temperature of electrophoretic paint is too high, the volatilization of cosolvent in the paint will be accelerated, the stability of electrophoretic paint will decrease, and the aging will be accelerated, which will also lead to thicker paint film, rough surface, or abnormal particles in the electrophoretic paint film,Serious can lead to electrophoresis paint scrap. Therefore, the temperature of the electrophoretic bath paint solution has a great influence on the electrophoretic coating, So we have to take measures to solve the problem of electrophoresis bath temperature rise，The temperature of electrophoretic paint can be controlled by water jacket, cooling pipe and other measures, at present, the most commonly used way is to use the direct cooling tank liquid of cold and heat exchanger to realize cooling. The temperature control effect is better than that of conventional water chillers and other temperature control methods, and the efficiency is high,Daily electrophoresis production management must regularly check the operation of these devices, to ensure their normal operation. Only the normal operation of the equipment can guarantee the quality of the product, so as to achieve efficiency gains.
