How to adjust the automatic spray gun

The adjustment of spray gun mainly refers to the adjustment of air volume and paint output. These are two interrelated main factors. The amount of air out is too small to atomize the paint liquid, and the paint liquid will drop in drops, which will make the film uneven. The amount of paint output corresponds to the amount of air output. Before spraying, adjust the appropriate amount of air output and the corresponding amount of paint output to make the paint liquid atomize well and spray evenly on the surface. To adjust the spray gun, one should listen to the sound of the air flow and know the size of the air flow. Several important parameters of the spray gun are as follows: air pressure: the air pressure for spraying is generally (0.4-0.6 Mpa). Spray width: the width of spraying on the working surface is about 10cm. Spraying distance: during spraying, the distance between the nozzle and the object to be sprayed is 15-20cm. Moving speed: the moving speed of the spray gun is generally 30-60cm/s. Heavy coating range: the overlapping range of each gun during spraying is 1/2 - 1/3 (except for crack paint). Spraying angle: the angle between the nozzle and the object to be sprayed is generally 90 °
