Problems needing attention in automatic spray gun operation

There are many friends who want the editor to respond that there will always be problems like this and that when the automatic spray gun is operating, and the spraying effect is not ideal. How can we avoid it? Today, the editor will tell you a few problems that need to be paid attention to when operating the automatic spray gun. .

1. Control of the trigger

The automatic gun is controlled by the trigger. The deeper the trigger is pulled, the greater the fluid flow rate. In the process of traditional shooting of spraying equipment, the trigger is always pulled, not half-pulled. In order to avoid the buildup of paint sprayed at the end of each shot, experienced painters should loosen the trigger slightly to reduce the amount of paint supplied.

2. The orientation of the spray gun to the surface of the substrate

The spray gun should be kept vertical to the surface of the substrate, or as vertical as possible. If the automatic spray gun is a little skewed, the result will definitely cause the spray strip to flow on one side, while the other side looks dry and lacks paint, which is very likely to cause a streaky coating.

3. Moving speed of automatic spray gun

During the spraying operation, 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 object to be coated will be thin, appear dry, poor leveling and rough;

2. If the moving speed of the spray gun is slow, the coating film on the surface of the object to be coated must be very late, and it is easy to cause sagging.

3. The ideal moving speed of the automatic spray gun is that after the spraying is finished, the surface coating of the object to be coated is full, uniform and wet. This requires operators with certain spraying experience to control.

Fourth, the interval between the spray gun and the surface of the substrate

For the siphon gun, the best working interval is 15~20cm. If they are too close together, they may run, and may even cause the color to be inconsistent when sprayed with metallic or pearlescent paint. If the distance is too far. If it exceeds 20cm, it may lead to dry spraying and overspraying, which will deteriorate the leveling of the paint. There may also be a possibility of color change if sprayed with metallic glitter paint. The pressure feed gun can be farther away from the substrate, and the best interval is generally 20 to 30 cm. These are the principles that must be followed during spray construction.

5. Holding the gun gesture.

The paint 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. Some painters change the way they hold the gun from time to time when they work for a long time. Sometimes they only use the thumb, the palm and the little finger, and sometimes they use the ring finger to hold the gun, and 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 problems that need to be paid attention to in the operation of automatic spray guns. If you can pay attention to these problems, you can reduce unnecessary troubles and improve work efficiency.
