the advantage of al. powder coating

There are three kinds of surface treatment methods for aluminum profiles: anodizing, electrophoretic coating and powder spraying, each of which has its own advantages and occupies a considerable market share. Nan Yi Lian is here to talk about the advantages of powder spraying for aluminum profiles

1. The process is relatively simple, mainly due to the improvement of the automatic accuracy of the main equipment in the production process. The microcomputer control of some main technical parameters can be realized, which effectively reduces the difficulty of process operation, and greatly reduces the number of auxiliary equipment;

2. The finished product rate of aluminum profile is high. Generally, if the measures are appropriate, the generation of unqualified products can be controlled to the maximum extent;

3. The energy consumption is obviously reduced. In the production process of ordinary anodizing and electrophoretic coating, the consumption of water and electricity is quite large, especially in the oxidation process. The output current of the rectifier can reach 8000 ~ 11000A, and the voltage is between 15 ~ 17.5V. In addition to the heat consumption of the machine itself, it needs to use circulating water to cool down continuously. The power consumption per ton is often about 1000 degrees. At the same time, the reduction of auxiliary facilities can also reduce some power consumption;

4. The pollution degree of water and air is reduced, flake alkali, sulfuric acid and other liquid organic solvents are no longer used, which reduces the pollution of water and air, effectively improves the competitive strength of aluminum profile and plastic steel profile as environmental protection products, and correspondingly reduces some production costs;

5. Due to the use of automatic assembly line operation, the feeding mode and the use of fixtures have been significantly simplified, which improves the production efficiency and reduces the labor intensity;

6. The powder coating can completely cover the extrusion lines on the surface of the profile, cover up some defects on the surface of the profile, and improve the surface quality of the finished aluminum profile;

7. Compared with other surface treatment films, some physical indexes of aluminum profile coating film are obviously improved, such as hardness and wear resistance, which can effectively extend the service life of aluminum profile.
