Tips for painting production line:
The powder spraying production line is one of the main products of the coating equipment. Now we provide some coating tips for customers.

1. General
The purpose of mastering correct spraying techniques is to save paint, obtain coatings that meet quality requirements, avoid the consumption of paint quality and physical strength, and reduce the probability of waste products. Through the correct training of coating operation skills and turning this skill into a habit, not only the production efficiency can be improved, but also the film quality can be improved. Below we will introduce the basic techniques used when using airless or general air atomization equipment.

2. Preparation before painting
The spray gun and related equipment shall be cleaned and in normal working condition. Check whether the spray gun produces the ideal spray shape. The ideal spray should be symmetrical, uniform and clear. Only a few paint mist particles can exist outside the spray edge. The capacity of the configured air compressor should meet the requirements of the equipment operation manual. For example, GPQ6C airless spraying machine requires an air consumption of 300-2500L/min, and should be equipped with an air compressor of 1.6-2.5m3 or 2.5m3. In order to ensure sufficient air intake, the inner diameter of the air outlet pipe of the air compressor and the air pipe connected to the inlet of the spraying machine shall not be less than the diameter of the air inlet pipe specified in the type specification.

3. Spraying pressure
Conditions for achieving appropriate atomization pressure: low atomization pressure required to achieve ideal atomization of liquid Therefore, the principle to follow when adjusting the pressure is: "spray has a good shape and the set pressure is right" (the pressure should be as low as possible) Excessive pressure will not improve the quality of the coating, will only shorten the life of the equipment and increase the wear of the nozzle, and will make the coating rebound, waste the coating and pollution space.
