(1) In order to give full play to the characteristics of powder coating and prolong the service life of the coating film, the surface of the object to be coated should first be 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 coated objects with large surface defects, conductive putty should be applied to ensure the smoothness and smoothness of the coating film
(4) After spraying, the objects need to be heated and cured, and the curing conditions are subject to the technical indicators 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 spraying. If defects are found, they should be dealt with in time. If defects are found after curing, their range is small and only partially does not affect. The surface decoration of the coated object can be repaired after dilution with the same color powder and acetone. If the range is large It also affects the surface quality, after sanding with sandpaper, spray again or use paint remover to remove the coating, and then re-spray.
(6) The recycled powder must be screened to remove impurities, and then mixed with new powder in a certain proportion.
(7) The powder supply bucket, powder spray room and recovery system should avoid the pollution of other powders of different colors, so it must be cleaned every time when the color is changed.

Storage method
1. Keep away from fire, avoid direct sunlight, and place in a well-ventilated place with a temperature below 35°C.
2. Avoid storing in places that are easily polluted by water, organic solvents, oils and other materials.
3. Do not expose the powder coating to the air at will after use, and should cover or close the bag tightly at any time to avoid mixing of sundries.
4. Avoid long-term skin contact. The powder attached to the skin should be washed with soap and water. Do not use solvents. Safety of painting construction site
5. The equipment used for painting work must be well grounded to eliminate static electricity.
6, to avoid the phenomenon of unexplained discharge of the coating machine
7. In the powder spraying room, the concentration of floating dust should be controlled below the safe concentration as far as possible to avoid the danger of dust catching fire and explosion.
