How is e coating similar to electroplating?

2021.3.24

E coating is the process of depositing another resin ion on the surface of a metal surface. The phenomenon in which charged particles (ions) move in an electric field. Electroplating is the process of plating a layer of other metals or alloys on certain metal surfaces using electrolysis.

 

  1. 1. from the function
    Electroplating is a process of attaching a metal film to the surface of a metal or other material by electrolysis, thereby preventing metal oxidation (such as rust), improving wear resistance, electrical conductivity, light reflectivity, and corrosion resistance (copper sulfate) Etc.) and enhance the appearance of beauty. Electroplated with a metallic texture.
    E coating is only high imitation plating, performance, color still has a certain gap. E coating is difficult to make a metallic texture of plating.
    However, in terms of uniformity of the paint film, the film thickness of the electrophoretic paint coating is high and low, and the plating of the high and low potential of the plating layer is not uniform.
    E coating is also more advantageous in coating film coatings. E coating can completely cover hidden areas, such as inner walls and depressions; and electroplating generally cannot penetrate deep into concealed areas.
    E coating can only be applied to electrically conductive metal surfaces; plating can be plated on specially treated plastics in addition to metal surfaces.

  1. 2. in terms of cost
    Electroplating is a layer of metal plated, while e coating is a layer of resin. Electrophoresis is simpler and easier to operate than electroplating. So from the cost point of view, the electrophoresis is much cheaper than electroplating.

  3. 3. from an environmental
    e coating uses water as a solvent, with less waste and less environmental pollution.
    Electroplating wastewater contains heavy metal ions such as chromium, cadmium, nickel, silver, and cyanide, which are prone to pollution.
