The essentials of the spray gun operation

First, the speed of the spray gun.

When spraying, the speed of the spray gun has a great influence on the painting effect.

1. If the manual spray gun moves too fast, the surface coating of the coated object is thin, which is thin and thin, and has poor leveling and roughness;

2. If the manual spray gun moves slowly, the surface of the coated object must be very late, and it is prone to sag.

3. The ideal speed of the spray gun is that after the spraying, the surface coating of the coated object is full, uniform and moist. This requires an operator with a certain spray experience to control.

Second, the control of the trigger.

The spray gun is controlled by a trigger. The deeper the trigger is, the greater the liquid flow rate. Electrostatic spraying equipment In the process of traditional gun shooting, the trigger is always buckled, not half buckle. In order to avoid the accumulation of paint sprayed at the end of each shot, experienced painters should slightly relax the trigger to reduce the amount of paint.

Third, the orientation of the spray gun on the surface of the substrate.

The gun should be perpendicular to the surface of the substrate or as vertical as possible. If the spray gun is slightly skewed, the result will necessarily cause the spray belt to run sideways, while the other side will appear thin and lacking paint, which is highly likely to cause a striped coating.

Fourth, the spacing of the spray gun to the surface of the substrate.

For siphonic spray guns, the optimum working interval is 15~20cm. If the spacing is too close, there may be a runny that may even cause color to be inconsistent with expectations when sprayed with metallic glitter or pearlescent paint. If the interval is too far. If it exceeds 20cm, it may cause dry spray and overspray, which may deteriorate the leveling of the paint. If the metal glitter paint is sprayed, there may be a possibility of color change. The pressure-feeding spray gun can be farther away from the substrate. Generally, the optimum interval is 20 to 30 cm. These are the principles that must be followed when spraying.

Fifth, hold the gun.

The spray gun is held by the palm, thumb, little finger and ring finger. The middle finger and index finger are used to pull the trigger. Some painters work over a long period of time to change the way the gun is held from time to time. Sometimes they only use the thumb, the palm to match the little finger, and sometimes the gun with the ring finger. The middle finger and index finger are used to pull the trigger. Electrostatic spraying equipment can alleviate fatigue and improve work efficiency.
