Analysis of Advantages of Aluminum Powder Powder Spraying on Broken Bridges

[China Aluminum Industry Network] 1. The technology is relatively simple. It is mainly due to the advancement of the active precision of the primary equipment in the production process. For some of the primary technical parameters, microcomputer control can now be achieved, effectively reducing the technical difficulty of operation and assisting the equipment together. Greatly reduced

2. The rate of finished products is high. Under normal circumstances, if all measures are taken properly, the occurrence of defective products can be controlled at a greater limit.

3. The energy consumption is significantly reduced. In the general production process of anodizing and electrophoretic coating, the consumption of water and electricity is appropriate, especially in the oxidation process. Rectifier output current can reach between 8000 ~ 11000A, the voltage between 15 ~ 17.5V, coupled with the machine's own heat consumption, demand for continuous use of circulating water for cooling, tons of electricity consumption is usually around 1000 degrees, Accompanied by the reduction of equipment 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 will no longer be used. Water and air pollution will be reduced. It will also effectively improve the competitive strength of broken bridge aluminum profiles and plastic steel profiles as environmental protection products. Correspondingly reduced some production costs;

5. The labor intensity of workers has dropped significantly because of the use of an automated assembly line, the method of feeding materials and the application of fixtures have now been significantly simplified, and production power has been improved, and labor intensity has also been reduced.

6. The specification of appearance quality of wool has been significantly reduced. The powder coating can completely cover the kneading lines of the appearance of the profile, cover some of the defects of the broken aluminum profiles, and improve the appearance quality of the broken aluminum profiles;

7. Some of the physical goals of the coating are significantly better than those of other exterior treatment films, such as hardness, wear resistance, and acid resistance, which can effectively extend the service life of broken aluminum profiles.

The powder coating is selected from powder coatings. The technique used is electrostatic spraying. Using the function of the friction spray gun, under the influence of accelerated wind, the powder particles are sprayed out of the gun body with a positive charge and touched with the negatively charged profiles. Electrostatic adsorption occurs and then cures at high temperatures. It also enhances the coating's strength and prevents the paint film from falling off.

From the point of view of technology itself, with appropriate high-tech components, different colors and different colors of paint, different colors of the decoration effect, more and more in line with the needs of interior decoration, but also with the application of aluminum bridge in the construction industry to the interior The trend is consistent. In particular, the combined application of sprayed profiles and thermal break bridges has made them more fashionable and has given the powder sprayed profiles greater room for development. It is also an alternative to other profiles that cannot be replaced.
