Electrostatic coating is a method of painting that uses charged particles to more efficiently paint a workpiece. The atomized paint is charged statically by the equipment as it emerges through the nozzle. Centrifugal force is used to drive the paint out of the equipment. The substrate that needs to be painted is usually grounded so that it can be sought by the charged paint. The paint then adheres around the substrate. For excellent electrostatic painting Denver offers a good place to pay a visit.
In complex applications, the workpiece is made to go down a conveyor into a paint booth or paint tank. In the paint tank, the workpiece is either coated with or dipped into the paint. Paint booths usually have a powder recovery module, which is used to remove between 95 to 100 percent of overspray coatings. The workpiece then proceeds down on the conveyor belt into an oven where curing happens.
Painting that is done electrostatically has several advantages over the use of conventional methods because of various reasons. First, the level of wastage is very low because of the recovery unit which recovers overspray paint. Costs are cut further through process automation. However, some models of this machine are operated manually.
The recovery unit operates by sucking back any particles of the paint that do not make it to the substrate. The particles turn in the air and go back into the unit. One major disadvantage associated with this method is that all components making up the area near the substrate should be grounded. Failing to ground everything around the workpiece may lead to a buildup of static charges which may cause arcing and other damages to the painted component.
Before using the system, it is important that all component comprised in it are cleaned well. Thorough cleaning helps to avoid causing shock to the individual operating the equipment. Higher quality can also be achieved when the system is cleaned thoroughly. In comparison to traditional painting equipment, the equipment used for electrostatic paining is much more expensive. However, the cost can be recovered shortly through reduced cost of labor and materials.
Much preparation is needed in this process before the actual painting. Removal of debris is the first process of preparation, and it is important to ensure that materials such as debris, graffiti, dust, mold, and old paint among others are removed completely. One of the best ways of removing surface debris is through sandblasting. To attain better adhesion, one should sand the surface of the workpiece.
After sandblasting and sanding, the surface needs to be wiped thoroughly using various kinds of solvents and/or degreasers. There is a wide range of solvents and degreasers in the market that one can use for this purpose. In case there are some parts of the workpiece that do not need to be painted, it is important to mask them before starting to work.
One can improve the results achieved by applying a primer on the substrate first. In the same way, the modern market has various primers to pick from. When the process is done, masked areas should be unmasked and those that are removed replaced. Proper cleaning should be the last phase of the work.
