Through the comparison between the two, it can be clearly found that the aluminum alloy extruded profiles without surface treatment have a single appearance and are prone to corrosion in humid atmosphere. Therefore, in order to enrich the appearance of aluminum profiles and extend their service life, aluminum profiles generally need surface treatment Spray processing It is one of the commonly used surface treatment methods.

The electrostatic powder spraying method is mostly used for aluminum profile spraying. The induction effect of high voltage electric field is used to induce the powder coating and the coated object to carry opposite charges respectively, so that the charged powder coating can be adsorbed onto the opposite charged coated object. Then the powder coating can be fused, leveled, baked and solidified to obtain the required coating film.

Facts have proved that after the aluminum profile is sprayed, not only the product surface is rich in color and soft in texture; And the performance has also been greatly improved. For example, good corrosion resistance is not easy to be polluted, and good weather resistance can extend the service life of the product; In addition, the powder coating is durable and simple to produce.

Since the aluminum profile spray processing effect has been recognized, powder spraying has developed rapidly. However, with the implementation of the national energy conservation and emission reduction policy, and the improvement of aluminum profile enterprises' awareness of cost control, reducing the powder consumption in aluminum profile spray processing has become the top priority.

There are many factors that affect the powder consumption in the spraying process of aluminum profiles. On the one hand, it is related to the nature of the powder coating itself, and on the other hand, it is closely related to the powder spraying process, which specifically involves the spraying process conditions, workpiece spacing, equipment use status, staff operation level, etc.
