Electrostatic Spray Gun Powder

An electrostatic spray gun is a key part of an electrostatic technique that is utilized to apply electrostatic coating materials. In this method, a protective coating is applied over a surface using the electrostatic spray gun and then compressed air is sprayed over the protective coating at a very high velocity. This will cause the coating to be electrically charged. Electrostatic spray guns are usually very large guns that fire as many rubber balls at one time.

A conventional electrostatic spray gun consists of a large, heavy gun that shoots out thousands of rubber balls. The size of these guns is based upon the amount of coating to be sprayed. Large guns are better suited for spraying large amounts of coating, while small guns are better suited for spraying a relatively small amount of coating. The reason for this is that large guns spread the electrostatic charge over a much larger area, thereby providing a greater charge for the coating.

Coating applications must be controlled to prevent damage to the surface being painted. To do this, electrostatic spray guns must have enough length to allow spraying the coating at a considerable distance from the nozzle. If too short, you will damage the paint and your finished project. Likewise, if too long you will be spraying the coating too close to the nozzle and it will not be covered sufficiently. The actual distance from the gun and the painting surface should be set with a gauge, or a number that can be used to determine the distances.

A second important factor to consider in electrostatic spray painting is the thickness of the coating. The thickness of the coating will depend upon the amount of charge and the temperature that it is expected to be exposed to. For example, an application that requires less than a volt of current, such as a spray painting application to drywall, will require a thicker coating than one requiring a comparable voltage, such as a coat applied to wood. The reason for this is the difference in voltage creates a lower potential for ionic bonding. The thicker the coating, the less likely it is that the ionic bonding will occur, which means the higher the potential for damage.

When choosing between electrostatic spray guns that use a low or high gun voltage, you also need to consider the length of the hose or spray. The longer the hose or spray the more potential there is for electrostatic discharges. Longer hoses/sprays are generally made from materials that are not easily affected by static discharges. However, even these factors can affect how long the hose is appropriate.

The third factor to consider when purchasing an electrostatic spray gun involves the consideration of electrostatic attraction and its effects on the coating material. Electrostatic attraction occurs when an electric current passes through a material that contains some type of surface tension, whether it be a metal plate polymer film or even plastics. The attraction occurs due to the difference in potential between the charged conductor and the non-charged conductor. While the difference in potential is not enough to produce an electrical charge, it does create a potential for attraction.

Electrostatic efficiency is also an important consideration when looking at electro spray guns. The efficiency of electrostatic performance spray guns is generally measured in terms of the amount of time it takes for the sprayed powder to be completely dispensed from the canister or cartridge. This is typically measured in inches per minute, where 100 inches per second is the typical efficiency rating for traditional sprays. However, there are a variety of other factors that can affect the efficiency of the product, including spray tube length and the type and length of the spray nozzles, as well as various types of primer and additives used in the performance spray gun powder.

In order for electrostatic spraying to be effective, the coating being sprayed must be made of a non-permanent material, such as plastic, which will not be damaged by the electrostatic spray and is not conductive to the electrostatic spray. Additionally, the coating must have a higher rate of electrically conductive material, such as metal, due to the electrostatic charges. In addition to coatings having a higher level of conductivity, materials with a high moisture content will also prevent the coating particles from becoming negatively charged ions. Electrostatic spraying products that achieve this result will provide a much smoother and easier application process, as well as providing a higher level of coating satisfaction.
