The hand-held liquid electrostatic spray gun operates based on the electrostatic spraying principle. It utilizes the grounded object to be coated as the positive electrode and the paint atomizing device as the negative electrode. By applying a high negative voltage to the atomizing device, an electrostatic field is created between the electrodes, causing the atomized paint particles to become negatively charged. This enables the paint to be effectively adhered to the grounded object.

The liquid electrostatic spray gun has been widely adopted in the market. Its popularity is growing due to its high paint utilization rate, increased painting productivity, superior painting quality, and significant reduction in waste paint and mist, as well as a decrease in environmental harm. A complete set of liquid electrostatic spray gun mainly consists of the electrostatic generation equipment, the electrostatic spray gun body, an air-driven diaphragm pump for paint supply, and other spraying accessories. The equipment is easy to understand and operate.

The handheld liquid electrostatic spray gun is suitable for metal parts, carbon fiber products, electroplating maintenance, automotive parts, and steel furniture, and is also used for the application of conductive coatings; it has been widely used in various industries.

Section 1: Maintenance of Electrostatic Spray Gun Bodies

1. Keep the spray gun clean regularly. When cleaning, do not submerge the gun body in the solvent. Hold the spray gun and carefully clean it with a soft brush and cloth dipped in the solvent.

2. Other than for defects, no random disassembly is allowed. Disassembly is only permitted to replace parts due to defects for the sake of gun body sourcing.

3. The spray gun should be hung on a hook at all times and the power to the control box should be turned off when not in use for short periods.

4. To achieve the miniaturization of the spray gun, the body is made of resin materials, which are designed with strength in mind. However, caution should still be exercised to prevent dropping it to avoid unnecessary damage.

Maintaining the Electrostatic Spray Gun Nozzles

At the end of the task, thorough cleaning is not mandatory.

2. When cleaning clogged nozzle, do not use metal wires or other metallic objects. Instead, soak in a solvent and then use compressed air to blow it out; do not use metal cleaning.

3. Regular cleaning of the nozzle is essential during operation. Paint residue attached to the nozzle can result in poor atomization and affect the static generation effect.

III. Maintenance of Paint, Air Hoses, and Cable Lines

Maintain cleanliness; avoid adhesion of paint and other contaminants.

2. Avoid using mechanical impacts (such as being trampled by feet, pressed by objects, or run over by vehicles)
