Must know aluminum profile advantages of powder coating

In the last blog, we discussed the surface treatment methods of aluminum profile. There are three surface treatment methods for aluminum profile: anodizing, electrophoretic coating and powder spraying. Each method has its own pros and occupies a considerable market share. Click here to view a more comprehensive surface treatment method. In this article, we pay greater attention to the aluminum profile powder coating.

👍 Significant advantages

The process is relatively simple

Mainly because the automation precision of the main equipment in the production process is improved, some main technical parameters can be controlled by a microcomputer, which effectively reduces the difficulty of process operation and greatly reduces the auxiliary equipment.

High output

Generally speaking, if the measures are taken properly, the occurrence of nonconforming products can be controlled to the greatest extent.

Significantly reduced energy consumption

In the production process of ordinary anodized electrophoretic coatings, water and electricity consumption are large, especially in the oxidation process. The output current of the rectifier can reach 8000 ≤ 11000 A, the voltage is between 15 and 17.5 V, plus the heat consumption of the machine itself. Circulating water is needed to keep cooling, and the power consumption per ton is often about 1000 degrees. At the same time, the reduction of auxiliary equipment can also reduce part of the power consumption.

Reduce pollution

Reduced water and air pollution, no longer use alkali, sulfuric acid and other liquid organic solvents, reduced water and air pollution, effectively improved the competitiveness of aluminum profile and plastic steel profiles as environmentally friendly products, and reduced some accordingly Cost of production.

Reduce work intensity

The labor intensity of workers is significantly reduced, and the automatic assembly line operation significantly simplifies the feeding method and the use of fixtures, improves production efficiency, and reduces labor intensity.

Lower the standard

The requirements for the surface quality of the wool have been significantly reduced. The powder coating can completely cover the extruded particles on the surface of the profile, cover up part of the aluminum profile surface defects, and improve the surface quality of the aluminum profile finished product. 7 Compared with other surface treatment films, some physical indicators of the coating have been significantly improved, such as hardness and wear resistance, which can effectively extend the service life of the aluminum profile.

Powder spraying adopts powder spraying and electrostatic spraying in the process. Using the action of friction spray gun, under the action of accelerating wind, the powder particles carry a positive charge when ejecting the gun body and contact the contour with negative charge to generate electrostatic adsorption. Under curing, improve the adsorption strength of the coating and prevent the coating from falling off.

From the perspective of the process itself, it has a high technological content. The paints of different colors are mixed together, resulting in different color decoration effects, which is more in line with the needs of interior decoration. It also moves toward the interior with the application of aluminum profile in the construction industry.

The development trend, especially the combined use of sprayed profiles and thermally-insulated bridges, makes it more fashionable, so that powder sprayed profiles have more room for development and cannot be replaced by other treatment methods.
