What are the surface treatment processes of aluminum profiles?
The surface treatment methods of these aluminum profiles are both the same and different. The same point is that a protective film is added to the surface of the aluminum profile; the difference is that fluorocarbon spraying and powder spraying rely on electrostatic filming on the surface of the aluminum profile, so it is also called electrostatic spraying. ;Anodic oxidation and electrophoresis are the protective film formed by the positive and negative poles of direct current and the positive and negative phase attraction and movement of the molecules, atoms and ions forming the film to attach to the metal surface;

Electroplating and anodic oxidation, electrophoresis art have similarities, the difference is: the electroplating may not be metal, the electroplating solution is composed of compounds containing plating metals (zinc, chromium, nickel, etc.), conductive salts, buffers, Aqueous solution composition of pH adjuster and additives etc.:
1. Electroplating can process hardware and plastic.
2. Electrophoresis and anode can only process conductive objects. the
3. Both electroplating and electrophoresis increase the material on the surface of the object to be processed, in other words, the thickness increases. the
4. Anodizing is to remove material from the object, that is, the thickness will be reduced after anodizing.
