Construction reference
Construction method: spraying, voltage 50~100kv, air pressure 0.5~1.5kg/cm², spraying distance 150~300mm, coating thickness 60~80um, curing temperature 180℃/15min or 200℃10/min.
Construction instructions
The workpiece should be pre-treated before spraying to thoroughly remove surface contaminants. The compressed air should be oil-free and water-free and the oil-water separator should be checked frequently for normal operation. The working chuck should be of appropriate size and cleaned regularly to maintain good connection with the grounding transmission part. The powder feeder, powder gun and recycling system should be free of pollution and should not be mixed with powder coatings of different manufacturers or models, otherwise it will affect the appearance of the final coating. The temperature in the oven should be uniform, and the temperature difference of each part should not be greater than ±5℃ to reduce color difference. The recycled powder coating must be sieved and then mixed with new powder in the specified proportion. Dust should be avoided in the construction site to avoid affecting the appearance of the coating.
