What are the advantages and uses of automatic powder spray guns?

Automatic powder spraying equipment can save a third of energy consumption. The air extraction recovery effect of the automatic powder spraying equipment is better. After the opening area of ​​the spraying room is reduced, the negative pressure of the spraying room section increases, which can prevent the powder from spilling. And there are no fragile and consumable parts. *The automatic powder spraying equipment adopts advanced cyclone and nano-coated filter element recycling technology, which can increase the powder separation rate by about 2 points, and can reduce about 15 tons of waste powder every year.

OPTIGUN 2-A AUTOMATIC POWDER GUN - COMPLETE type quick color-changing spray booth has less powder adhering, and at the same time, it adopts an automatic cleaning device, and the color change can save about 1/2 time compared with the traditional vertical line color-changing spray booth. Automatic powder spraying equipment is environmentally friendly. Imported nano-coated filter element with 0.1um filtration precision is adopted, and exhaust gas is directly circulated indoors. [Development status of automatic powder spraying equipment] In recent years, the government has vigorously promoted environmental protection. As a green technology in the spraying field, automatic powder spraying equipment meets the requirements of environmental protection policies such as VOC energy saving and emission reduction, and has been increasingly favored by customers.
The high-voltage static electricity in the work is provided by the high-voltage static generator. When spraying, it should be grounded first. Under the action of purified compressed air, the powder coating enters the electrostatic spray gun from the powder feeder through the powder pipe. The head of the spray gun is equipped with a metal ring or pole needle as an electrode. The end of the metal ring has a sharp edge. When the electrode is connected to high-voltage static electricity, the tip will generate a corona discharge, which generates a dense negative charge near the electrode, and the powder is removed from the static electricity. When the powder spray gun head sprays, the captured electric charge becomes a charged powder, which flies to the grounded workpiece under the action of chlorine flow and electric sound, and is adsorbed on its surface.
According to different principles, it is used for spraying different products, such as long-necked spray guns suitable for spraying the inner cavity of products: S-1 type with long-necked single nozzle, GNPQ2F type with long-necked double-nozzle, and long-necked curved nozzle W type, There is also a horizontal spray nozzle suitable for spraying the inner wall of the pipe, and the paint mist is sprayed around in a plane perpendicular to the gun body. The neck length, nozzle size, and uniform paint output of the above products can be changed according to requirements. For spray paint lines with large batches and simple shapes, KZ-1 DSK spray guns can be used. The opening half of the spray gun is automatically controlled by pneumatic components, which can realize automatic spray painting according to the shape of the flat workpiece.
