The narrower the powder size distribution, the better: to control the powder size reasonably, we have to adjust the rotation speed of the main and auxiliary mills of ACM in our actual production. The particle size of powder is important, 40-50um is suitable, and the narrow distribution is better.

The spray chamber should be kept clean and the ground powder recovery should be as pure as possible. After passing through a 100 mesh sieve, the pure recycled powder is mixed with the new powder according to 20% of the added amount. Or in the process of double spraying, directly use recycled powder ......

Powder coatings have the advantages of energy saving, environmental protection and excellent performance. Compared with traditional liquid coatings, powder coatings have the advantage of solvent-free evaporation. However, in the actual spray curing process, a small number of small molecular substanc......

In most cases, the electrostatic spray gun is used for coating, because this type of product contains metal pigment. When using the electrostatic spray gun, the excellent grounding of the system should be ensured, and a lower electrostatic voltage and powder output should be set together to prevent ......

Metal pigments have many color products, which greatly enrich the varieties and decoration of powder coatings. Commonly used metal pigment varieties are: aluminum silver powder pigment, pearlescent pigment, copper gold powder pigment, etc.

Environmental protection coatings are also divided into exterior wall coatings and interior wall coatings. Some people can't help asking whether interior and exterior wall coatings can be used in general? Let's first understand the standard requirements of interior and exterior wall coatings.
