Cataphoretic coatings of anode

From the perspective of production process, the paint-making process equipment of electrophoretic coatings is basically the same as that of general color paints. However, because electrophoretic coatings use water-soluble resin and electrophoretic coating technology, there are some differences in the paint-making process. Require.

Water solubility, the main influence of the resin on the paint-making process is the change of the viscosity of the resin during the dilution process. The rule is that the viscosity decreases when a small amount of dilution is added, and the viscosity increases when water is added. When a sufficient amount of water is added, the viscosity increases. Decrease rapidly; attention should be paid to the change of its viscosity during the whole dilution process, the diluent-water should be added slowly under stirring until it is evenly stirred.

In the sequence of material preparation, the resin should be added first, and then the powder should be added after adding water and mixing thoroughly, which will help the dispersion.

Due to the change of dilution viscosity, it is recommended to use a variable speed agitator, and adjust the speed of the agitator according to the change of viscosity. If this special equipment is not used, when selecting the agitator, the motor should have sufficient power to ensure the normal operation of the equipment.
