The amount of   paint produced during spraying is too small or too large. The spraying   distance is too far or too close. Poor atomization of spray gun and excessive   paint mist particles.

Choose a nozzle   with a suitable caliber, and adjust the appropriate air pressure, spraying   distance, oil output and spraying speed according to the paint requirements.

The temperature   of the workpiece is too high, so that the solvent volatilizes instantly, and   the wet film is too late to level.

Reduce the   temperature of the surface of the coated object.

When the paint   viscosity is too large, the paint atomization and wet film leveling are poor.   Too much thinner or unsuitable.

Use the matching   diluent and adjust the amount of diluent to be added.

The   environmental humidity is high. Or enter the baking room when the flash time   is insufficient.

Control the   temperature and humidity of the painting environment to extend the flash-out   time.

The air flow   rate in the spraying room is too fast, so that the wet film solvent   evaporates quickly and is difficult to level.

Reduce the   temperature and wind speed of the spraying environment to slow down the   solvent evaporation rate.

The rough substrate can easily 

cause short-wave orange peel.

Carefully polish,   choose the appropriate sandpaper model and polishing method to eliminate the   roughness of the coated surface.
