Our company specializes in the production and operation of
electrostatic spraying equipment and spare parts (electrostatic
spraying machine, and electrostatic spray gun, electrostatic spray
gun shell, circuit board, double pressure module, stainless steel
powder barrels, powder nozzle, powder pump, etc.). The performance
is superior, the powder is large and uniform, and the powder rate
is high on the dead corner.
The description of electrostatic spraying process
On the tip of the electrostatic spray gun, negative high-voltage
static electricity is connected. When the voltage is high enough,
the air in the vicinity of the gun head generates a strong corona
discharge, forming a gas ion region. When the paint particles
atomized by the electrostatic spray gun are in this region, the
atomized particles of the paint are negatively charged. When the
coated workpiece is suspended on a grounded conveyor line, there is
a positive charge on the surface of the workpiece. According to the
electrostatic principle of heterogeneous charge attraction, the
negatively charged coating mist particles move toward the
heterogeneous working surface, and adsorbed and deposited on the
surface of the workpiece to form a uniform dense film, then the
workpiece is coated.
1) It is advisable to use thermosetting coatings, and thermosetting
plastics should not be used in high temperature curing coatings.
2) Good dryness.
3) It is well atomized in the electrostatic field and has a certain
4) Fineness and low viscosity.
5) Good hiding power and high viscosity.
Electrostatic spraying production process:
Pre-treatment of the workpiece surface → drying → electrostatic
painting → leveling → baking (heating into film) → cooling → remove
