Working principle of powder coating line

The core working principle of the Линия порошковой окраски is based on electrostatic adsorption and high-temperature curing. First, in the spraying process, a high-voltage electrostatic generator is used to generate a high voltage at the spray gun head, and the workpiece is grounded to form an electric field. When the powder coating is sprayed from the spray gun, the powder particles are charged when they come into contact with the spray gun head. Under the action of the electric field force, the charged powder particles quickly move to the surface of the workpiece with the opposite charge and adsorb on the surface of the workpiece to form a uniform layer of powder coating. Subsequently, the workpiece adsorbed with the powder coating is sent to the curing furnace. Under high temperature (generally between 180-220℃, depending on the type of powder coating), the powder particles melt, level, and solidify, and finally form a hard and dense coating on the surface of the workpiece, achieving the protection and decorative effect of the workpiece.
