1. Since electrophoresis must be carried out under the power of electricity, it is applicable to the conductive coating, such as wood, plastic and other insulators.
2. After baking and curing, the insulation layer is formed and the secondary electrophoresis coating is not possible with normal electrophoresis coating.
3. It is not suitable to apply electrophoresis coating process for different metal combinations of different properties. If there are some electrophoresis coatings for Cu, Su and other progress ions, it can cause allergic reactions.
4. After electrophoresis, the resulting wet film has to be roasted, so that it can be solidified into a dense coating, so that the coating cannot be applied to the high temperature.
5. The requirement for the update period of electrophoresis is 6 months, so it is not suitable for small batch production, otherwise it will affect the stability of the working fluid.
6. It requires strong technical support, especially in color electrophoresis, to achieve the desired color effect, and it is difficult to adjust color.
7. Electrophoresis coating is a specialized industry which must strictly strengthen process management. The engineering management personnel must have sufficient field experience to deal with the unexpected problems.
8. Changing the color difficulty is not suitable for the job of constantly changing the color of the product layer.
Nine, hang the hook part for covering the electrodeposition layer insulation, must ensure that hang in contact with the work, conductive performance is good, easy to remove and replace, so the hanging fixture design, the manufacture is a vital problem.
10. Not suitable for floating objects, such as the coating of automobile and tractor fuel tank, etc.
