Precautions for metal spraying gun use
During the spraying process, the spray gun is held by the palm, thumb, little finger and ring finger, and the middle and index fingers are used to pull the trigger. Spray gun manufacturers need to work for a long time and will change their holding method from time to time. Sometimes they use their thumb and palm with only their little finger, and sometimes they use their ring finger to hold the gun. The middle and index fingers are used to pull the trigger. The airbrush can relieve fatigue and improve work efficiency.
The moving speed of the spray gun has a great effect on the spraying. If the spray gun moves too fast, the surface coating of the coating will be thin, dry and thin, poor leveling and rough; If the spray gun moves slowly, the coating must be late and prone to flow. The ideal movement speed of automatic spray gun is: after spraying, the surface coating of the coated object should be uniform and wet. This requires some spraying experience to control.
When using paint spray gun, we need to pay attention to the following situations, which are naturally the paint atomization under low pressure. Therefore, the rebound rate of the paint during spraying will naturally be lower than the rebound rate of the high air pressure spray gun. This low pressure spray gun will be larger than the high pressure spray gun, and will leave little paint in the air, so we also called environmental paint spray gun. This makes it more protective of our use.
