Many friends would like to respond to this question. When the automatic spray gun is in operation, there will always be problems such as this. The spraying effect is not ideal. How can I avoid it? Today, I will tell you a few issues that the automatic spray gun needs to pay attention to during operation. .
一 、 Control of trigger
Automatic spray gun is controlled by trigger. The deeper the trigger is pulled, the greater the fluid flow rate. In the process of spraying equipment, the trigger is always snapped, not half-tucked. In order to avoid the accumulation of paint sprayed out at the end of each gun, experienced painters should slightly relax the trigger to reduce the amount of paint supplied.
2. Orientation of spray gun to substrate surface
The spray gun should be vertical to the surface of the substrate, or as vertical as possible. If the automatic spray gun is slightly skewed, the result will surely cause the spray band to flow to one side, while the other side will look thin and lack paint, which is likely to cause a striped coating.

Three, automatic spray gun moving speed
When spraying, the moving speed of the paint spray gun has a great influence on the painting effect.
1. If the spray gun moves too fast, the coating on the surface of the coating is thin, and it looks thin, poor, and rough;
2. If the moving speed of the spray gun is slow, the coating film on the surface of the coated object must be very late, and the phenomenon of sagging is easy to occur.
3. The optimal moving speed of the automatic spray gun is that the coating on the surface of the coated object is full, uniform and wet after spraying. This requires operators with some spraying experience to control.
4.从喷枪到表面的距离of the substrate
最佳 For siphon spray gun, the best working interval is 15 ~ 20cm. If the interval is too close, flow may occur, and the color may not match the expected when spraying metallic glitter paint or pearl paint. If the interval is too far. If it exceeds 20cm, it may cause dry spray or overspray, which will deteriorate the leveling property of the coating. If the metallic glitter paint is sprayed, there may be a possibility of color change. The pressure-feed spray gun can be farther from the substrate, and the optimal interval is generally 20 to 30 cm. These are the principles that must be followed when spraying.
Fifth, holding a gun gesture.
The paint spray gun is held by the palm, thumb, little finger and ring finger. The middle finger and index finger pull the trigger. Some painters change the way of holding the gun from time to time, sometimes using only the thumb and palm with the little finger, and sometimes with the ring finger to hold the gun. The middle and index fingers are used to pull the trigger. The spray gun can relieve fatigue and improve work efficiency.
The above are the issues that need attention in automatic spray gun operation. If you can pay attention to these issues, you can reduce unnecessary trouble and improve work efficiency.
