Electrostatic spraying powder construction

Principle of electrostatic spraying powder:

Electrostatic spraying uses the principle of high-voltage electrostatic corona electric field. The metal guide cup on the spray gun head is connected with the high-voltage negative electrode, the coated workpiece is grounded to form a positive electrode, which forms a strong electrostatic field between the spray gun the workpiece. When the carrier gas (compressed air) sends the powder coating the powder supply barrel to the guide cup of the spray gun through the powder conveying pipe, the corona discharge is generated due to the high-voltage negative electrode connected to the guide cup, the dense electric charge is generated around the guide cup, the powder carries negative charge. Under the action of electrostatic force compressed air, the powder is evenly absorbed on the workpiece. After heating, the powder is melted solidified into uniform, flat smooth Coating.

Process guidance for electrostatic spraying powder:

Powder coating is a new solvent free 100% solid powder coating. Two categories: thermoplastic powder coatings thermosetting powder coatings. The coating is prepared by mixing special resin, pigments fillers, curing agent other additives in a certain proportion, then by hot extrusion, crushing screening. They can be used for coating, coating, coating, coating, coating, coating, coating, coating, coating coating.
