An electrostatic spray gun can be a great tool to use for many different painting projects. There are a number of different applications for these types of guns, but they are most commonly used in interior painting. Electrostatic paint guns are also referred to as static guns or pressure guns. These guns use static electricity to create an electrical charge instead of the typical chemical properties of paint. This type of charge is often used in industries, electronics, and motion control applications.
How do electrostatic spray guns work? Electrostatic spraying works by applying an electrical charge to paint. The positively charged paint is then shot at a grounded item and the negatively charged Paint will seek out the nearest surface (usually the item itself) that will lower the amount of electrostatic charge that is present. The larger the object, the greater the amount of charge that will be generated. The smaller the object, the less charge will be created and the paint will just drop down to the ground.
There are two types of electrostatic spray guns. One uses a combination of chemical and physical reactions to produce the electrostatic charge and another uses a conductor. Both types of electrostatic painting guns can create a very effective paint application. Just keep in mind that the greater the size of the charges, the more conductive the paint will have.
Some types of electrostatic spray painting guns use an airless or non-airless gun pressure pot to assist airless function. When using an airless gun pressure pot you will still need a supply of air. The air can be supplied from the air intake on your vehicle or from a nearby air tank. When using a non-airless pressure pot, you will still need to supply a supply of pressurized air.
There are several different types of electrostatic spray guns. One type of spray gun is the standard hvlp spray gun and it consists of two halves, each half is similar to a spray can. To utilize the spray gun, you first insert both halves into the canister, spin the canister and apply the hvlp spray. This type of spray gun typically requires less pressure than some other types of electrostatic hvlp spray guns.
Another type of electrostatic spray guns includes the electrical discharge (ED) system. This system uses a small positive charge and produces negative charges to attach to the metal that is being sprayed. The negative charges are similar to the electrostatic charge that occurs when the human hair touches metal. These systems are commonly found in law enforcement applications. They produce a very little amount of electrostatic energy but they can be extremely effective. The cons of these systems include limited applications, slow speed, and require constant recharging or replacement.
The third type of electrostatic spray guns are the air assist airless spray guns. These types of guns utilize an inert gas to produce the electrostatic energy. These types of guns are extremely effective in applications where the area to be sprayed is not easily accessible or controlled. The inert gas generally consists of argon, krypton, or neon. The gas has a lower density than air, thus making the gas easy to propel through the nozzle.
The last type of electrostatic atomization device are made conductive through the application of a conductive material. These materials generally consist of glass, plastic, metal, or rubber. While this method will not produce an electrostatic charge, it is effective and can easily reduce the amount of time needed to apply the electrostatic charge to the area. These types of electrostatic atomization devices are typically used in laboratories and other controlled environments.
