Powder coating, sometimes referred to as electrostatic spray painting, is a method of applying dry paint to a surface. Compressed air is used to drive atomized paint particles through a spray gun to the target. This process occurs when paint is applied to an object using an air-pressurized spray gun. Spray guns evolved from airbrushes, and the two are usually distinguished by their size and the size of the spray pattern they produce.
In addition, unlike a pure airless spray gun, an AA gun has some control over fan spraying and round spraying. The fluid pressure is provided by an airless pump, which allows much heavier materials to be sprayed than is possible with an air spray gun. HVLP spray equipment uses spray gun atomization technology that drives large amounts of low-pressure air to the gun applicator. This technique allows you to apply the paint evenly around the entire object and use UV light to dry the painted surface. Harold Ransburg founded Ransburg Electrostatic Equipment and found that electrostatic spray painting was an immediate success, as manufacturers quickly realized the significant material savings that could be achieved.
Linear spray systems are generally for products that are placed flat on a conveyor belt and then introduced into a linear spray system, in which automated spray guns are placed on top. Spraying paint with compressed air dates back to its use on the South Pacific railroad in the early 1880s. In 1887, Joseph Binks, the maintenance supervisor at Marshall Field's wholesale store in Chicago, developed a hand-pumped cold water paint spray machine to apply lime to the walls of the store's subbasement. Manufacturers that mass-produce wood products use automated spraying systems, allowing them to paint materials at a very high speed with a minimum of staff. There are a variety of portable paint sprayers that combine paint with air or convert paint into tiny droplets and accelerate them out of a nozzle.
Most have a paint pump (also called lower) which is a double-acting piston, in which the piston pumps paint both down and up.
