The technology of powder coating is simple which is due the improvement of the spray machine. Some of the main technology can be control by the micro computer. It’s good for reduce the difficult of the controlling by people.
1. High yield rate. Usually, we can control the defect product if our processing is appropriate.
2. Energy consumption is reducing. The consumption of water and electric is high in the processing of anodizing and Electrophoresis. Especial in the processing of anodizing, the output electric of Rectifier is in 8000-11000A. The Voltage is 15-17.5 V. In addition to the heat consumption of the machine itself, it is necessary to use circulating water to cool down.
3. The power consumption per ton is usually around 1000 degrees. A reduction in auxiliary equipment can also reduce some power consumption;
4. Reduce the pollution of water and air. Alkali, sulfuric acid and other liquid organic solvents are no longer used, reducing water and air pollution, and also effectively improving the competition strength of broken aluminum profiles and plastic steel profiles as environmentally friendly products, and correspondingly reducing some production costs
5. Reduce the requirement of the surface of aluminum extrusion products. Powder layer can cover the knitting on the surface to improve the quality of finish aluminum products.
The coating can help the aluminum profiles get higher Hardness, wear resistance, acid resistance. And it can Extend the lifetime of aluminum profiles.
Powder coating is use the powder to do the spray. The technical is electrostatic spraying, using the role of friction spray gun. Let the powder spray by the gun have positive charge.The powder comes into contact with the negatively charged profile, electrostatic adsorption occurs, and then solidifies at a high temperature. It also enhances the absorption strength of the paint and prevents the paint film from falling off.
From the technical point of view, it has a suitably high technological composition, distributing paints of different colors, and the decoration effect of different colors occurs, which is more in line with the needs of interior decoration. It is also the application of broken bridge aluminum profiles in the construction industry to the interior. The trend is consistent. In particular, the combined use of sprayed profiles and thermally broken bridges makes it more fashionable, and powder sprayed profiles have a larger development space, which is also irreplaceable by profiles produced by other disposal methods.
