Common Issues and Solutions in Electrophoresis Painting

Coating Unevenness

Coating unevenness may be caused by unstable voltage, poor pretreatment of the workpiece surface, or uneven stirring of the electrophoretic tank solution. For unstable voltage, check whether the power equipment is working properly and if there are any issues such as poor contact. If there is, carry out timely repairs or replacements. For poor pretreatment of the workpiece surface, reassess the processes such as degreasing, pickling, and phosphating to ensure each step meets the standard requirements. For uneven stirring of the electrophoretic tank solution, check whether the stirring device is operating normally, adjust the stirring speed and mode, and ensure uniform distribution of coating particles in the tank solution.

Coating Bubbles

Coating bubbles may be caused by excessively high drying temperatures, moisture on the workpiece surface, or an unreasonable coating formulation. For the problem of excessively high drying temperatures, readjust the temperature settings of the drying furnace to ensure the temperature is within an appropriate range. For moisture on the workpiece surface, strengthen the drying treatment of the workpiece before electrophoresis to ensure the surface is free of water stains. For an unreasonable coating formulation, communicate with the coating supplier to optimize and adjust the coating formulation, enhancing the stability and adaptability of the coating.

Methods to Handle Poor Coating Adhesion

Poor coating adhesion may be due to poor-quality phosphating film, oil stains on the workpiece surface, or improper electrophoresis painting process parameters. For poor-quality phosphating film, check whether the phosphating process parameters are correct, such as the concentration, temperature, and time of the phosphating solution, and make adjustments and optimizations; for oil stains on the workpiece surface, strengthen the degreasing process to ensure the workpiece surface is thoroughly clean; for improper electrophoresis process parameters, reevaluate and adjust the voltage, current, and time parameters to improve the coating adhesion.
