The differences between electrophoresis and anodized for aluminum profiles

What is the difference between electrophoresis and anodized?

The same point: all use electricity to complete the processing technology.

The difference: there is not much difference in appearance, but the texture is different. Anodizing is oxidized first and then colored, while electrophoresis is directly colored. The two are originally different processes. Anodized is a functional surface treatment with additional coloring, generally mainly on aluminum. On the other hand, electrophoresis focuses on decorative performance, but it is paint after all, and the metallic feeling may not be so good. Electrophoresis is equivalent to applying a layer of resin paint to the metal surface. And anodized is to use electrochemical method to make the surface metal aluminum and oxygen react to form a protective film, the surface has a metallic texture, and the grade is higher. It will be better if the electrophoresis is performed after oxidation.

anodized: anodized, the electrochemical oxidation of a metal or alloy. Aluminum and its alloys are a process in which an oxide film is formed on an aluminum product (anode) under the action of an applied current under the corresponding electrolyte and specific process conditions. Anodizing, if not otherwise specified, usually refers to sulfuric acid anodizing. In order to overcome the defects of aluminum alloy surface hardness, wear resistance, etc., expand the scope of application, and prolong the service life, surface treatment technology has become an indispensable part of the use of aluminum alloys, and anodized technology is currently the most widely used and most successful. of.

Electrophoresis: Under the action of an electric field, charged particles move toward the electrode opposite to it, which is called electrophoresis (EP). The technique of using charged particles to move at different speeds in an electric field to achieve separation is called electrophoresis.
