After comparison, it can be clearly found that the aluminum alloy extruded profiles without surface treatment have a single appearance and are easily corroded in a humid atmosphere. Therefore, in order to enrich the appearance of aluminum profiles and prolong their service life, aluminum profiles are generally subjected to surface treatment, and aluminum profile spraying is one of the more commonly used surface treatment methods.

Most of the aluminum profile spraying processes use electrostatic powder coating method, which uses the induction effect of high-voltage electric field to induce the powder coating and the object to be coated and carry opposite charges respectively, thereby adsorbing the charged powder coating to oppositely charged The object is coated, and then the powder coating is melt-leveled and baked to obtain a desired coating film.

It turns out that after the aluminum profile spraying process, not only the surface color of the product is rich, the texture is soft; and the performance has also been greatly improved, such as good corrosion resistance is not easy to be contaminated, and better weather resistance can prolong the service life of the product; The powder coating is durable and easy to produce.

Since the recognition effect of aluminum profile processing has been recognized, powder coating has developed rapidly. However, with the implementation of the national energy conservation and emission reduction policy and the awareness of cost control by aluminum profile enterprises, reducing the powder consumption in aluminum profile processing becomes heavy. The weight of the middle.

There are many factors affecting the powder consumption in the aluminum profile spraying process. On the one hand, it is related to the nature of the powder coating itself, on the other hand, it is closely related to the powder coating process, specifically related to the spraying process conditions, workpiece spacing, equipment usage status, and employees. The level of operation and so on.
