What are the advantages of aluminum powder surface coating?

Aluminum surface treatment methods are generally anodizing, electrophoretic coating and powder coating three treatment methods, each have their own advantages, occupy a considerable market share

Among them, powder spraying has the following significant advantages:

1, the process is relatively simple, mainly due to the automatic precision of the main equipment in the production process to improve, for some of the main technical parameters can be achieved microcomputer control, effectively reduce the difficulty of process operation, while greatly reducing the number of auxiliary equipment;

2. The rate of finished products is high. Under normal circumstances, if all measures are properly implemented, the generation of defective products can be controlled to the greatest extent possible.

3, the energy consumption is significantly reduced, in the ordinary anodizing, electrophoretic coating production process, water, electricity consumption is quite large, especially in the oxidation process. Rectifier output current can reach between 8000 ~ 11000A, voltage between 15 ~ 17.5V, coupled with the heat loss of the machine itself, need to keep cooling water circulating, ton power consumption is often around 1000 degrees, At the same time, the reduction of auxiliary facilities can also reduce some power consumption;

4. The degree of pollution to water and atmosphere is reduced. The use of caustic soda, sulfuric acid and other liquid organic solvents is no longer used to reduce water and air pollution. It also effectively improves the competitiveness of aluminum profiles and plastic steel profiles as environmentally friendly products. Reduced some of the production costs;

5. The labor intensity of workers has been significantly reduced. Due to the use of automated assembly line operations, the feeding method and the use of fixtures have been significantly simplified, which has increased production efficiency and reduced labor intensity.

6. The requirements for the surface quality of the wool are obviously reduced. The powder coating can completely cover the extrusion lines on the profile surface, masking the flaws on the surface of a part of the aluminum profile, and improving the surface quality of the finished aluminum profile. 7 Some physical indicators of the coating film Compared with other surface treatment films, it has obvious improvement, such as hardness and wear resistance, which can effectively prolong the service life of aluminum profiles.

Powder coating adopts powder coating. Electrostatic spraying is used in the process. The role of the friction spray gun is used. Under the influence of accelerated wind, the powder particles are carried positively when they are sprayed out of the gun body, and they come into contact with negatively charged profiles. Electrostatic adsorption followed by high temperature curing. It also enhances the coating's strength and prevents the paint film from falling off.

From the point of view of the process itself, it has a very high technological composition, and the deployment of paints with different colors will produce decorative effects with different colors. It is more in line with the needs of interior decoration, and is also in line with the development trend of aluminum profiles in the construction industry. Consistent. In particular, the combined use of spray profiles and thermal break bridges has made them more fashionable, enabling powder sprayed profiles to have more room for development and also being unreplaceable by other processing methods.
