1. Working principle:
(1) Under the action of high pressure (generally 10~20kv) air ionization to form a negative oxygen ion layer; Negative oxygen ions and atomized paint particles combine to form paint fog;
(2) Corona discharge occurs between the paint mist particles and the workpiece surface (i.e., directional movement of charge);
(3) It is neutralized by positive and negative ions on the surface of the coated part, and thus deposited into a coating; Oxygen in the air is also involved in chemical reactions. Therefore, it has the advantages of high efficiency, energy saving and environmental protection.
2. Features:
Suitable for all kinds of metal and non-metal materials processing and anti-rust treatment; It is especially suitable for the processing of workpiece with complex shape and not easy to access. For example: auto parts, hardware parts, etc. For or special workpiece processing effect is particularly good. Such as ship shell, etc. Can adapt to the coating needs of different thicknesses; Easy to operate, easy to master; The construction quality is stable and reliable; A wide range of applications.
Wide range of applications: less investment and quick effect; Long service life.
3. Classification:
According to different classification methods can be divided into the following three categories:
Class A is a manual sprayer;
Class B is semi-automatic spraying machine;
Class C is a fully automatic spraying machine.
4. Structure composition:
Nozzle:
There are many types of nozzle structure, commonly used flat mouth (also known as round mouth), conical and perforated three types.
The conical nozzle is widely used because of its good flow field and uniform flow distribution.
