Electric painting is currently one of the most efficient techniques of painting of modern times. This is achieved by the use of an electric spray painter. Its more efficient in the painting of large surfaces with a consistent color or in the painting of very complex surfaces such as metal grills, furniture and where the use of other painting tools is rendered ineffective or obsolete. This ensures this tight angle surfaces are painted with relative ease. However, using an electric paint sprayer requires significant practice in using the equipment to attain an even paint layer.
Different spray equipments have been in the market for decades. It has been found that airless sprayers are the easiest to use by non skilled personnel. An electric airless sprayer works on the principle of ejection of paint under high pressures thus necessitating careful handling to avoid increased hazard risk. An electric airless painting system comprises of a paint holding can, a pump capable of developing high pressure heads, electric motor, housing assembly and valves to regulate pressure. It also contains auxiliary accessories such as: longer suction tubes, extension nozzles, and a cup to measure viscosity of the paint.
It’s extremely important to observe certain precaution measures when using an airless paint sprayer. This is because other sprayers offer may not offer serious problems when using them. The choice of a spraying tip is much governed by the paint consistency to achieved. But by the rule of the thumb is that the thinner the paint required, the smaller the tip to be used. The paint consistency similarly guides pump pressure to be used. Generally, light and thin materials such as lacquers ,stains and sealers need less pressure as compared to heavier materials such as walls and thick metal plates.
The electric spray painter enables the paint to spread by the application of electrostatics. The nozzle of the gun is charged and as the paint under pressure passes through the nozzle it acquires the charge. On impact with surface, the paint particles which have the similar charge repel each other thus spreading evenly on the surface. This employs the law of like charges repel while unlike charges attract.
