Types of Electrostatic Painting Lines

An electrostatic painting line is a device/system made for coating workpieces, usually metallic, with powder paint. Production plants often use this device in high-capacity metal surface finishing operations. There are three common types of electrostatic painting lines.

• Electrostatic spray. The electrostatic spray painting apparatus is commonly used to apply powder coatings to various materials, including metal. This device applies an electrostatic charge to the powder coating particles, causing them to spray outward in a fine mist. As the particles approach the surface of the item to be painted, they become negatively charged and are attracted to the positive charge of the object. The result is a uniform powder coating applied to the item's surface. Additionally, an operator can maneuver the spray gun to reach different angles and areas of the object that needs coating.
• Electrostatic rotary atomizers. An atomizer is a gadget that produces a mist or spray of fine droplets. The electrostatic rotary atomizer applies powder coating to workpieces in an automatic or semi-automatic method. The atomizers operate by rotating at high speeds while the powder coating is fed into them; this is then broken down into fine particles that are electrostatically charged. The charged particles are subsequently propelled towards the item to be coated, which is then negatively charged. Electrostatic atomizers have the advantage of providing an even coverage of coating material, reducing overspray, and enhancing material utilization.
• Electrostatic paint spraying booths. The electrostatic paint spray booth refers to an enclosed space set up for the painting of items. It offers protection to the painter and the item being painted from the surrounding environment. It also keeps the oversprayed paint from getting into other parts of the building or facility. The booth helps to direct the overspray to the filtration and extraction system, which makes it possible to recycle and accurately use the paint.

Specification and maintenance of electrostatic painting lines

Specifications

• Voltage: The voltage in an electrostatic spray gun varies with different manufacturers and models. For example, the Apollo 20 electrostatic spray gun has an electrostatic voltage of 80kV, while the Wagner GGT electrostatic spray gun has a voltage of about 100kV to 110kV.
• Air Pressure: The air pressure of the electrostatic spray gun also varies with different manufacturers and models. For example, the Apollo 20 electrostatic spray guns work at a spray air pressure of 2.0 to 4.0 bar (30 to 58 psi), while Wagner electrostatic spray guns operate at a range of spray air pressure of 1.0 to 2.5 bar (14.5 to 36.3 psi).
• Weight: The weight of electrostatic guns also varies by model and manufacturer. For example, the Apollo 20 lightweight guns weigh as low as 530g, while the DeVilbiss electrostatic spray gun weighs around 1.1kg.

Maintenance Tips

• Clean the gun regularly: Keeping the gun clean is important for its proper maintenance. This includes wiping the spray head with a clean cloth after each use and periodically deep cleaning the gun to remove any paint buildup.
• Avoid corrosion: Electrostatic spray guns are usually made of aluminum, stainless steel, or other materials resistant to corrosion. Hence, users should avoid corrosive environments or chemicals that could damage the guns.
• Handle with care: Electrostatic guns are sensitive and delicate instruments. They should be handled carefully to avoid dropping or banging them. Store them in a secure place when not in use.
• Use the right paint: Using the proper type of paint for the electrostatic spray gun is crucial. Not only will it ensure compatibility, but it will also improve the quality of the finish and the performance of the gun.
• Maintain the air compressor: An electrostatic spray gun requires an air compressor to function. Hence, properly maintaining the air compressor is also important for the electrostatic gun's consistent performance. This includes regularly oiling the machine and changing the air filter.
