New material manufacturers talk about the construction requirements of powder coatings

In the era of various new materials emerging in modern times, do you still only know traditional paints and coatings? Then you're definitely out. Today we will talk about a new coating product in new materials: powder coating. Compared to other liquid coatings, powder coatings are undoubtedly more convenient, environmentally friendly, energy-saving, labor-intensive, and effective. Most importantly, powder coatings are solid coatings that can be recycled.

The construction process of general powder coatings is divided into five steps: surface treatment of the coated material, electrostatic powder coating, melt leveling or cross-linking curing, cooling, and product. It's simple, but there are many key points to pay attention to during actual construction:

(1) In order to fully utilize the characteristics of powder coating and extend the service life of the coating, the surface of the coated material is first subjected to strict surface pretreatment.

(2) When spraying, the object to be coated must be completely grounded to increase the spraying efficiency of powder coating.

(3) For objects with significant surface defects, conductive putty should be applied to ensure the smoothness and smoothness of the coating.

(4) After spraying, the object needs to be heated and cured. The curing conditions should be based on the technical specifications of the powder product, but the curing temperature and time must be fully guaranteed to avoid quality accidents caused by insufficient curing.

(5) Check immediately after powder coating.

(6) Recycled powder must be screened to remove impurities and mixed with new powder in a certain proportion.

(7) The powder supply bucket, powder spraying room, and recycling system should avoid contamination from powders of different colors, so they must be blown clean every time the color is changed.

In addition, there are strict requirements for storing powder coatings:

1: Keep away from sources of fire, avoid direct sunlight, and place in a well ventilated area with a temperature below 35 ℃.

2: Avoid storing in places that are easily contaminated by water, organic solvents, oil, and other materials.

3: All equipment used for painting operations must be properly grounded to eliminate static electricity.

4: Avoid unnecessary discharge of the coating machine.
