Powder coatings manufacturers talk about the main components of powder coatings.

Powder coatings manufacturers describe the main components of powder coatings. Powder spraying is to use powder spraying equipment (electrostatic spraying machine) to spray powder coatings on the surface of the workpiece, under the action of static electricity, powder will evenly adsorb on the surface of the workpiece, forming powder coatings; powder coatings after high temperature baking leveling solidification, become the final coating of different effects (powder coatings of different kinds of effects); powder coatings. The spraying effect is superior to the spraying process in mechanical strength, adhesion, corrosion resistance and aging resistance, and the cost is also lower than the spraying process with the same effect.

The main parts of powder spraying: a set of electrostatic powder spraying system mainly consists of a powder supply device, a set or several sets of electrostatic spraying guns and control devices, an electrostatic generating device (usually installed in the electrostatic spraying gun) and a set of powder recovery device.

1) powder feeding device

In the powder feeding device, the powder is in a fluidized state, which is achieved by the action of compressed air. The powder is then siphoned by a high-speed flow of air to form a powder mixture, which is pumped through the Venturi powder pump, the powder conveying pipe, and eventually reaches the spray gun.

The powder transported to the spray gun can be controlled. Specifically, the parameters of powder and air can be adjusted separately, and the amount of powder produced and the atomization state of powder can be changed. Thus, different coating thickness can be achieved to meet the needs of different products. The powder feeder has sufficient capacity to provide sufficient pressure and flow even if the powder feeding pipe of the spray gun is 50 feet long.

(2) about static electricity

The high voltage and low current produced by the electrostatic generator cause the electrode needle located in the front of the lance to discharge in the air. When the powder is ejected through the nozzle, the powder particles are charged and reach the surface of the grounded workpiece through the double action of electrostatic adsorption and air flow.

The spraying gun can produce enough voltage to ensure the maximum coating effect. The maximum voltage can reach 100 kV. When spraying inner angle or deep cavity position, the spraying gun can effectively overcome the Faraday cage effect and ensure that the required surface of the workpiece can achieve good coverage and uniform film thickness.
