Take the gun. The armor spray gun is held by palm, thumb, little finger and ring. The middle and index fingers are used to pull the trigger. Some painters work for a long time, changing the way they hold guns from time to time. Sometimes they only use their thumbs and palms and little fingers, sometimes the ring finger is used to hold the gun. The middle and index fingers are used to pull the trigger. This can relieve fatigue and improve labor efficiency.

2. The direction from the spray gun to the substrate surface. The spray gun shall be perpendicular to the surface of the substrate, or as vertical as possible. If the spray gun is tilted slightly, the spray belt will inevitably flow to one side, while the other side looks dry and thin, which is likely to lead to paint like coating.

3. Distance from the spray gun to the substrate surface. For armor spray gun, the optimal working distance is 15-20cm. If the distance is too close, flow may occur, and when spraying metallic flash paint or pearl paint, the color may not even be as expected. If the distance is too far. If it exceeds 20cm, it may cause dry spraying and overspray, which will make the coating level taste. If metallic flash paint is applied, there may also be the possibility of color change. The pressure feed gun can be far away from the substrate. Generally, the optimal distance is about 20-30cm. These are the basic principles that must be followed when spraying.

4. The moving speed of the spray gun. During spraying, the moving speed of the spray gun has a great influence on the coating effect. If the spray gun moves too fast, the surface will be thin, flat and rough; If the spray gun moves too slowly and the coating is too thick, it is likely to cause sagging. The ideal moving speed of the spray gun should be such that once the spraying is completed, the new spraying layer looks so full and moist, neither dry, thin, barren, nor too stacked. In short, the moving speed of the spray gun shall be determined according to the specific conditions of the construction site. Generally speaking, just for relative comparison, the moving speed of the pressure feed spray gun is faster than that of other types of spray guns.

5. Trigger control. The China Chassis armor spray gun manufacturers is controlled by the trigger. The deeper the trigger is, the higher the liquid velocity is. In the process of traditional gun shooting, the trigger is always pulled dead, not half pulled. To avoid the accumulation of paint at the end of each shot, experienced painters should slightly relax the trigger to reduce the amount of paint supplied.
