What to pay attention to when purchasing spray guns

1. When spraying quality requirements are high, the spray gun with good atomization of paint nozzle shall be selected. On the contrary, due to large objects and low quality requirements, selecting a good atomizing spray gun will affect the efficiency
rate
2. When the amount of paint is small, the area of sprayed objects is small, and there are many kinds of colors, using a large spray gun will cause waste and cannot improve the quality. At this time, a gravity spray gun should be selected, because the spray gun has less paint capacity, it is convenient to change colors, and it saves thinner when cleaning the paint pot.
3. The nozzle diameter cannot be too large or too small. The larger the nozzle diameter, the greater the air pressure required, the more paint sprayed, and the higher the consistency of the paint required. The degree of coating neutralization is closely related to the caliber of the spray gun, the viscosity of the coating, the amount of exhaust air from the air outlet and the angle of arrangement. Therefore, the caliber and air outlet of the spray gun nozzle shall be selected according to different types of coatings, and the viscosity of the coating shall be adjusted.
