The specific influence of particle size distribution on the performance of electrostatic spray powder coatings:

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.

2. 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. Recovery rate

There is a problem of powder recycling in the production and use of powder coatings. Generally, the recovery rate of ultrafine powder with powder particle size is low. When the recovery 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 above is all the content shared by Yongji Industrial for powder coating powder coating.

Yongji Industrial Co., Ltd. is located in; Hometown of Chinese Coatings& mdash;— Shunde, Guangdong, covering an area of nearly 10000 square meters, is a high-tech outward oriented powder coating production enterprise that integrates research and development and operation.

The company was founded in 1997, and we have always adhered to the principle of 'riding'; User first, quality first; Our business philosophy is that in 2003, the company fully passed the ISO9001-2000 international quality management system certification. In 2004, it was evaluated by the National Quality Evaluation Center as; Chinese Quality Credit Enterprise;, The Yongji brand, built with high-quality products and excellent services, has won a good reputation among customers. In July 2018, the company underwent a comprehensive upgrade and passed the ISO9001:2015&ISO14001:2015 Quality&Environmental Management System certification.

Since its establishment, the company has maintained healthy, stable, and rapid growth. From two small production lines and a small factory with more than ten people in the early stages of construction, it has developed into a modern enterprise with an experienced and skilled technical and management team, with an annual output of over 15000 tons and annual sales exceeding 200 million yuan.
