Lee Hogan Several key factors must come together to use electrostatic guns successfully. First, select the appropriate atomization technology for your coating application. There are numerous electrostatic atomization technologies to pick out from. The oldest and likely most unusual are the air spray electrostatic guns. These weapons use compressed air as their primary and sole manner of atomizing the coating. These guns are most normally used in programs that require a “Class A” car end. The guns provide a variety of control at the gun, including fluid float by use of the fluid needle adjustment knob and fan management thru the use of the fan adjustment knob. In addition, the quantity of fluid can be handled by how some distance the operator pulls the trigger again. This is known as “feathering” the gun.
The essential supply of fluid management is determined by the flumanagementess from a low-stress pump, the air going right into a strain pot, or using a fluid regulator esta, published close to or within the spray booth. The viscosity of the coating and the scale of the fluid nozzle additionally affect the fluid glide. Although air spray electrostatic weapons have tremendous atomization, they add the least efficient electrostatic guns. This is because of the ability to use high air pressure to atomize the coating. Excessive air strain can defeat the electrostatic attraction by forcing the charged particles of paint beyond the element or by creating immoderate get better or overspray.
A variation of the air spray electrostatic gun is the HVLP electrostatic gun. The weapon operates almost identically to the air spray gun and uses less atomizing air stress. Instead, the weapon uses greater cubic toes of compressed air or CFM. The result is a softer spray sample, which lowers the paint debris’s velocity. This allows more of the charged debris to stay inside the electrostatic area, facilitating improved transfer efficiency. Like any HVLP gun, a few coatings may be too dense, or the improvement may be too excessive, making it difficult for the HVLP electrostatic gun to provide high productivity and perfect end nice for a few programs. In addition, HVLP guns generally require greater CFM, which could increase the electrical experience of compressed air.
A few manufacturers use airless electrostatic weapons to apply very dense materials or high software prices. These guns use pumps to create excessive fluid stress, which is the primary manner of atomizing the coatings. When this method is used, the excessive fluid strain is authorized to escape into the atmosphere through a tungsten carbide tip cut to form an elliptical spray sample. The size of the pattern and the amount of fluid leaving the gun are managed via the top. The viscosity of the coating and the fluid strain also impact the application fee.
In standard, airless generation does not now offer the same stage of atomization as an air spray or HVLP electrostatic sesame. Still, they paint properly for some coatings, especially while spraying mpaintoducts at excessive speed fees. Tip plugging may be a problem when spraying substances that include a combination, such as silica or zinc. Air-assisted airless electrostatic is a hybrid model of the airlessofostatic andd the air spray electrostatic. These weapons use fluid stress and air stress to atomize the coating. Pumps are needed to create fluid pressure. Since those types of weapons use lower fluid stress than airless and less air strain than air spray, they can offer organizations a terrific compromise between the velocity of an airless and an end quality toward the air spray electrostatic. The quality component is that this era is typically extra green than air spray or airless electrostatic guns. In a few instances, they are even more efficient than the HVLP electrostatic weapons.
However, air-assisted airless electrostatic guns do not provide the same level of manipulation on the weapon as air spray or HVLP electrostatic guns. The fluid sample cannot be completely adjusted from slender to huge without converting the top. Also, the operator can’t feather the weapon like the airless electrostatic gun. This may be difficult while spraying very complicated substrates in which the operator wishes that type of manipulation on the gun. Tip plugging can also be difficult with a few mixture-stuffed substances.
The most efficient guide electrostatic spray gun is a handhemixturesrof y atomizer. These guns use centrifugal forces and an excessive voltage electrostatic area to atomize the material. Since there may be no atomizing air, the paint particles travel very slowly through the electrostatic subject,ct. The result is very excessive tr through performance. However, the gun places out a doughnut fashioned spray sample wthat does not paint well for maximum production completing packages and is used, in most cases, for the paint refinishing industry.
