What does powder coating production do?

Powder coating production is a process of transforming some goods and services into powder coatings by using labor and capital under the responsibility, control and management of institutions.

Powder coating is a kind of powder coating composed of synthetic resin, filler, pigment, curing agent and additives. As a new type of environmental protection coating, powder coating has the advantages of less environmental pollution, low resource and energy consumption, low production cost and high production efficiency. With the increasing output of powder coatings, its application fields are gradually expanding. Powder coatings are gradually replacing other solvent-based coatings and becoming the most promising coatings in modern society.

Production principle of powder coating: solid materials such as synthetic resin, filler, pigment, curing agent and additives are added into the mixer for premixing according to a certain proportion and formula. The premixing process should be carried out without water or other solvents. The materials passing through the mixer are melted by the extruder at high temperature, and after being fully mixed, they are cooled in a cooling tablet press and pressed into sheets.

Crushed scales enter a cyclone separator, and the separated coarse powder is screened to obtain a finished powder coating product, and the fine powder is recycled. The production process of powder coatings does not involve any chemical reaction, and it is a purely physical process.

Influencing factors of powder coating quality

1, quality of raw materials

The quality of raw materials plays a decisive role in the quality and performance of powder coatings. So every kind of raw material should be chosen properly. The structure and properties of synthetic resin are the most important factors to determine the quality of powder coatings.

Step 2 make

In the formulation and selection of powder coatings, special consideration should be given to the internal relations of each component. Good miscibility of each component is the basis to ensure the quality of powder coatings. Ignoring this point, it is difficult to obtain ideal coating effect. The synthetic resin in powder coatings determines the basic properties of coatings.

3. Selection of production equipment

The production of powder coatings is a physical process. Production equipment has an important influence on the stability of formula and the quality of powder coatings. The selection of powder coating production equipment depends largely on the product type, quality requirements and production batch. Premixing is the first process in the production of powder coatings, which is to mix and disperse all components to form a good and uniform melt mixing system.
