The distribution of particles has such an impact on the use of powder coatings

With the continuous advancement of technology and the continuous development of society, the use of powder coatings and plastic powders has become increasingly widespread. In our daily lives, the use of powder coatings is very common, and the position and distance of particle distribution can actually affect powder coatings. This time, the powder coating manufacturer will take you to specifically understand the impact of particle distribution.

1. Appearance and leveling properties

Generally speaking, the smaller the particle size of the powder, the better the leveling performance of the coating during curing, and the appearance of the coating will be smoother and more even. However, the electrical charge of the powder is proportional to the square of the particle size. If the powder is too fine, the electrical charge will decrease, and the coating construction efficiency will decrease. Ultra fine powder basically does not carry electricity.

The powder coating rate is closely related to the electrical properties of the powder coating itself. Improve the charge capacity of paint particles and increase the powder coating rate. The charge of a particle is directly proportional to the square of its particle size. Increasing the particle size leads to an increase in the electrical charge of the coating particles and an increase in the powder coating rate. But the particle size should not be too large. If the particle size is too large, the gravity of the coating particles will exceed the aerodynamic and electrostatic forces, which will actually reduce the powder coating rate.

3. There is a problem of powder recovery in the production and use of powder coatings. Generally, the recovery rate of ultrafine powder with powder particle size is low. When the recovery rate of powder coating particles rapidly increases, and the recovery rate of powder increases with the increase of particle size. Even for the above reasons, it can be said that the particle size distribution of powder coating particles greatly affects the performance and efficiency of powder coating use. Therefore, it is necessary to have granularity detection equipment to monitor product quality and assist in the research and development of new products and technologies.

The reasonable use of powder coating can increase the exquisite level of many products. Apply the desired color on the surface of the product. Additionally, some anti-corrosion surfaces can be added to the product. Better ensure the rational use of powder coatings.
