With the continuous expansion of market demand, the output of aluminum alloy profiles is increasing rapidly, and the application fields are also constantly being explored. Aluminum alloy profiles have undergone many improvements and innovations in product quality, specifications and quality, making their application in new fields possible. Aluminum alloy profiles are widely used in the construction industry, and their coverage has gradually penetrated into the home industry. The common methods for surface treatment of aluminum alloy profiles include spraying, anodic oxidation and electrophoretic coating, which have their own advantages and characteristics.

Aluminum profile automation equipment

1. The powder spraying process is relatively simple, mainly due to the improvement of the automatic accuracy of the main equipment in the production process. Some main technical parameters can be controlled by microcomputer, which effectively reduces the difficulty of process operation and greatly reduces the number of auxiliary equipment.

2. The finished product rate of powder spraying is high, and the requirements for the original surface of the material are not high. Under normal circumstances, with proper measures, the generation of unqualified products can be controlled to a great extent, and the energy consumption is obviously reduced.

3. In the production process of anodic oxidation electrophoretic coating, the consumption of water and electricity is quite large, especially in the oxidation process, the output current of rectifier can reach 8000~ 11000A, and the voltage is between 15~ 17.5V V. Coupled with the heat consumption of the machine itself, it is often about 1000 degrees to keep cooling with circulating water, and the reduction of auxiliary facilities can also reduce some power consumption.

4. Anodizing, the degree of atmospheric pollution is large alkali; Sulfuric acid and other liquid organic solvents have great pollution to water and atmosphere.

5. The labor intensity of powder spraying workers is obviously reduced. Due to auto production line operation, the feeding mode and the use mode of fixture have been obviously simplified, which improves the production efficiency and reduces the labor intensity.

6. The requirements for the surface quality of wool are obviously reduced, and the powder coating can completely cover the extrusion lines on the surface of aluminum profiles, cover up some defects on the surface of aluminum profiles, and improve the surface quality of finished aluminum profiles.

7. Some physical indexes of the coating film are obviously improved compared with other surface treatment films, such as hardness; Wear resistance and aging resistance can effectively prolong the service life of aluminum profiles. Powder coating is used in powder spraying, and electrostatic spraying is used in the process. Under the influence of accelerating wind, powder particles carry positive charges and contact with negatively charged profiles to generate electrostatic adsorption, and then they are cured at high temperature, which also enhances the adsorption strength of coatings to prevent paint film from falling off.
