Aluminum Alloy Powder Powder Coating Process-Aluminum Profiles Supplier

Aluminum alloy profiles can be used for powder coating to obtain attractive surfaces and protect them from corrosion. This process is similar to liquid spraying. This is a special process that can produce attractive and durable coating with good adhesion and aging resistance. This technology is also used to produce decorative effects. Powder coating is a process that uses powder, resin and pigments to form attractive coating on aluminum. This process can be applied to solid and thin metals.

Generally, the thickness range of the coating surface is 50 to 300mm. Before coating the powder, the profile should be cleaned. This is washed by heat (pure), and then color water washing and neutral. These processes can remove stains and other foreign bodies on profiles. After the surface is cleaned, use the powder sprayer to spray the powder. In addition to removing stains, this program can also make the profile not easy to rust. Static powder coating on aluminum alloy materials has many advantages compared to other coating technology.

For example, it has a 95%high recovery rate and can be used at normal temperature conditions without preheating.

In addition, the powder coating process does not cause any pollution to the environment.

In addition, its uniformity makes the decoration look good. Anode oxidation is another technique of coating on aluminum materials. This is a process that involves heating aluminum alloys to 190 to 220 degrees. Then use phosphorus solution to promote the conversion coating. When aluminum squeezing and phosphate contact, phosphoricate will be deposited. Finally, the film will be removed.

At this time, the phosphate coating on aluminum will promote the combination of aluminum and powder coatings. The main difference between powder coatings and liquid coatings is that the former does not require solvents.

In addition, it has formed a dense and uniform oxide film, providing good anti -corrosion protection. It can also form a porous oxide film, which is the useful feature of electronic devices.

In addition, porous oxide membranes can suck lubricants and pigments, which can improve the wear resistance of the product. The decorative film is also possible. They can be printed with special paint prints or wood texture. Another advantage of using this method is the height temperature resistance of the film. Because the film forms a hard layer, it can withstand a breakdown voltage of 30 volts/mm. Powder coating aluminum profiles have different designs and colors.

However, they are not as tough as oxide. To ensure its quality, it should be applied to the surface of oxygers.

In addition, the color may not match the aluminum itself. The main disadvantage of the powder coating process is that the surface does not have the elasticity of aluminum.

In addition, coating may be prone to cracking.

If it is not treated, the powder coating product may be damaged.
