(1) In order to fully exert the special properties of the powder coating and prolong the service life of the coating film, the surface of the broken coating material is first strictly subjected to surface pretreatment. (2) When spraying, the object to be coated must be completely grounded to increase the spraying efficiency of the 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 object should be heated and solidified. The curing conditions are subject to the technical specifications of the powder product, but the curing temperature and time must be fully ensured to avoid quality accidents caused by insufficient curing. (5) Check immediately after dusting. If defects are found, they should be treated in time. If defects are found after curing, the range is small and only partial and does not affect. The surface of the coated object is decorated. It can be repaired with the same color powder and diluted with acetone, if the range is large. If the surface quality is affected, sanding with sandpaper, spraying once again or removing the coating with a paint remover, and then re-pulping. (6) The recovered powder shall be mixed with the new powder according to a certain ratio after screening to remove the impurities. (7) The powder supply bucket, dusting room and recycling system should avoid contamination of other different color powders, so be sure to purge each time you change colors.
