It is a way of road marking construction, spraying the atomized paint by compressed air.
After atomized by compressed air, the paint form a reticule coating when sprayed to the road surface.
Features of air spray painting
The paint is fine and smooth after atomization, but there is air rebound, so paint fly off is serious, to the line is drew not neat, with burrs. Besides, the applicable paint is of low viscosity, so more solvent was added during the construction, and it was a great waste. The coating is often thicker for low flow of the spraying gun, marking is of weak dynamic sense. Coating is affected by atomized water, oil molecules from the atomized air. The marking quality is not very perfect.
