What are the methods for the surface treatment of aluminum plates

- Mar 19, 2018-

The application of aluminum plate in the construction industry has been particularly extensive, especially the decoration materials. So the beauty of the aluminum plate is more concerned, now more manufacturers care more about the surface of the aluminum plate. There are 5 ways to treat the surface of the aluminum plate.

1. electrophoretic coating

Electrophoretic is one of the most effective methods for coating metal workpiece. Electrocoating is the conductive coated by electrophoretic coating at a relatively low concentration tank filled with water and diluted in (as anode or cathode), in the groove of another set of corresponding (cathode or anode), between the DC power after a period of time, was deposited on the surface of coated material uniform and dense without is a special kind of water soluble film coating method. In the process of electrophoretic coating, there are four kinds of chemical physical changes, namely, electrolysis, electrophoretic, electrodeposition, electroosmosis. This method of treatment is most commonly used in Japan now. After such treatment, the surface of aluminum sheet has a smooth surface, and its corrosion resistance will also increase.

2. powder electrostatic spraying

The electrostatic spray uses the principle of high voltage electrostatic corona electric field. The metal diversion cup on the head of the spray gun is connected with high pressure negative electricity, and the workpiece is coated with the workpiece to form a positive pole. A strong electrostatic field is formed between the spray gun and the workpiece. When the carrier gas (compressed air) will flow from cup of powder coating for powder barrels by the powder tube to the spray gun, the surrounding dense powder charge, with negative charge in the static electricity and compressed air under the effect of adsorption powder evenly on the surface of the workpiece, through heating, melting and solidification (or powder plastic film) into a homogeneous and continuous, smooth, smooth. The main feature is to enhance the corrosion resistance of the aluminum plate, and for some acid and alkali salt, the aluminum sheet is better than the oxide colored section.

3. abrasive treatment

The aluminum panel itself is very bright, but in our life, there will be some interference and highlights in certain environment. The use of frosted can be good customer service. Its surface is silky and smooth, which has been liked by many people.

4. hue surface treatment

The traditional aluminum color previously has been unable to meet the needs of some designers, in order to make better use of aluminum, appeared in the processing of various colors, the aluminum color becomes more perfect, the most important point is that all need to be treated with polishing after the oxidation effect is the best.

5. plasma enhanced electrochemical surface ceramics

This is the advanced science and technology used. The quality of the aluminum plate through this treatment is excellent, although the cost is high, but a penny of the goods. The most important thing is that the aluminum plate can also be used in a series of colors.
