Membrane malady and its treatment measures - low swimming permeability, dew bottom, secondary flow marks.

Due to the defects of people, machines, materials, French, rings and other factors on-site management, the surface of the coating film usually appears shrink holes, orange peels, pinholes and other defects, seriously affecting the appearance of the coating film and the quality of the coating film.
In order to obtain a good coating appearance and excellent film performance, this paper lists and analyzes the possible disadvantages and defects of electrophoresis coating film, and provides some effective treatment methods for reference.
1, coating membrane maladies: swimming permeability low swimming permeability is in electrophoretic paint, paint on the inner surface of the coating, dents and the back of the coating capacity, but also to make the complex coating of all surfaces can be applied with uniform paint film ability.
2, coating membrane ills: dew bottom electrophoresis coating film after baking, exposing the substrate part.
3, coating membrane ills: secondary flow marks in the electrophoresis coating film drying process, the paint liquid traces produced at the structure of the coating is called electrophoresis secondary flow marks.
