Advantage analysis of decorative aluminum profiles powder spraying treatment on surface

Update time : 2023-02-07 11:54:56

There are generally three decorative aluminum profiles surface treatment methods: anodic oxidation, electrophoretic coating and powder spraying, each of which has its own advantages and holds a considerable market share.

Powder spraying has the following significant advantages:

1. The process is relatively simple, mainly due to the improvement of automatic precision of main equipment in the production process, some main technical parameters can be controlled by microcomputer, effectively reducing the difficulty of process operation, and greatly reducing the auxiliary equipment;

2. High yield of finished products. In general, if all measures are appropriate, the generation of unqualified products can be controlled to the maximum extent;

3. Energy consumption is significantly reduced. The output current of the rectifier can reach 8000~11000A, the voltage between 15~17.5V, plus the heat consumption of the machine itself, need to keep cooling with circulating water, ton power consumption is often about 1000 degrees, and the reduction of auxiliary facilities can also reduce some power consumption;

4. The pollution degree of water and air is reduced, caustic acid, sulfuric acid and other liquid organic solvents are no longer used, reduce water and air pollution, but also effectively improve decorative aluminum profiles and as environmental products of plastic steel profiles competitive strength, reduce some production costs accordingly;

5. Some physical indicators of the coating film compared with other surface treatment film has significantly improved, such as hardness, wear resistance, can effectively prolong the service life of decorative aluminum profiles.

Powder spraying is powder coating, the process is electrostatic spraying, using the effect of friction spray gun, under the influence of accelerating wind, the powder particles spray gun body carrying positive charge, and negatively charged profile contact, electrostatic adsorption, and then through high temperature curing.
