Introduction to the composition and structure of powder spraying process
Powder electrostatic spraying equipment mainly includes: powder spraying room, high-voltage electrostatic generator, electrostatic spraying gun, powder feeder, powder recovery device, workpiece rotating mechanism, etc.
Powder spraying process powder spraying room
The powder spraying room is one of the main equipment for powder electrostatic coating. Maintaining a smooth air flow is what keeps the booth clean and provides operators with a clean working environment. Control the dust content in the spray booth so that it is lower than the explosion limit (generally set at 10g/m3). In addition, the powder spraying room should be easy to clean, so that the powder is not easy to deposit in the room, so as to change the color of the powder, and there should be enough light in the room to facilitate the coating work.
Powder spraying process electrostatic spray gun
Classification: spray guns can be divided into portable powder spray guns, fixed automatic powder spray guns, disc spray guns, etc. according to their uses; according to the form of electrification, they can be divided into inner electric guns and outer electric guns; according to the form of their diffusion mechanism, they can be divided into conflict Type gun, rebound type gun, secondary air inlet type gun, centrifugal rotary cup type gun, etc.
Spraying efficiency: The electrified mechanism of the powder spray gun is a key factor in improving the spraying efficiency. Generally speaking, the core of powder spraying equipment is the spray gun and charging system. As far as the current market is concerned, the proportion of corona spray guns is very large, because the biggest advantage of using high-voltage corona discharge to charge powder is that it can spray all types of thermosetting powder coatings today. And can get very good results. Its advantages are mainly manifested in excellent stability, powdering rate and powdering speed.
The development of the gun is like this: voltage control o current control o total energy control. The total energy control is that with the distance between the spray gun and the workpiece, the voltage and current are constantly adjusted to the ideal state to achieve the best coating effect.
Powder supply system for powder spraying process
The powder supply system is to continuously and evenly transport the coated powder from the powder container to the powder spray gun for spraying. The powder supply system consists of air compressor, oil-water separator, air dryer, regulating valve, compressed air pipeline, electromagnetic control valve, powder supply device, powder conveying pipeline, etc.
Form of powder feeder:
In the powder electrostatic spraying powder supply system, there are many types of powder supply devices, which can usually be divided into: pressure container type, mechanical conveying type of screw or rotary table, and Venturi air suction type.
Powder recovery device:
The recovery of powder can be divided into wet method and dry method. The wet method is to filter the air with powder through a liquid container to achieve purification, and the powder with liquid is dried and reused.
