The way to provide best quality :

The powder should be taken to ensure the film thickness, the general control is conducive to the formation of distinct patterns and larger pattern in the 70 ~ 100 m to thin film, the pattern is not obvious, but also a small pattern, at the same time there will be open at the end of pitting and other defects.

Powder coating is a new kind of solvent free 100% solid powder coating. There are two main types: thermoplastic powder coating and thermosetting powder coating. Coatings are made of special resins, pigments, fillers, curing agents and other additives in a certain proportion, and then prepared by means of hot extrusion and crushing and screening. They are stored at room temperature, stabilized by electrostatic spraying or fluidized bed immersion coating, and then heated, baked, fused and cured to form a smooth, permanent coating for decorative and anti-corrosion purposes.

construction requirements, general powder spraying construction requirements:

(1) in order to give full play to and extend the service life of the coating, the surface of the coating is strictly treated by surface pretreatment first

(2) when spraying, the coating must be completely ground to increase the spraying efficiency of the powder coating

(3) to be coated with larger surface defects, it should be coated with conductive putty to ensure the smooth and smooth coating

(4) after the spraying, the objects and articles should be heated, cured and cured. The technical indexes of the powder products should be adopted. However, the curing temperature and time should be guaranteed so as to avoid the lack of solidification and cause quality accidents.

(5) check immediately after spraying, if found defects should be timely treatment, if after curing defects are found, the only local small range without affecting, the coated surface decoration, can use the same color powder and acetone diluted to repair, if the scope is large and affects the surface quality, use sandpaper after again. Or use the paint remover to remove the coating, re Suo powder.

(6) the recovered powder must be screened and removed, and then mixed with the new powder at a certain proportion.

(7) the powder supply barrel, the powder spraying room and the recycling system should avoid contamination by other colors. Therefore, each color change must be cleaned.
