(1) In order to fully utilize the characteristics of powder coating and extend the service life of the coating film, the surface of the coated object is first subjected to strict surface pre-treatment.

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

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

(4) After spraying, the object needs to be heated and cured. The curing conditions shall 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) Immediately inspect after powder spraying.

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

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