Dear steemians. How are you today? I hope you are good. Today I want to share about Car Painting Process Using Electrostatic Technology.

Technological developments today are very advanced. Almost all lines of life are influenced by technological advances. One of them is painting technology or often also called coating. So far, we have known the process of painting using a brush. Both the usual brush and the wheel-shaped brush can be moved up and down on the layer to be painted. The process of painting has developed so that the painting technique appears by spraying with air brush.

Both painting techniques we are familiar with the classical techniques. There are several weaknesses of classical techniques. Among them is a slow painting process that is less effective and efficient. In addition paintwork is not too flat, as we expected. Therefore, it is necessary to develop a painting technique that is able to overcome the weaknesses of classical techniques. The painting technique developed should be faster with the result of evenly painting. Now it is found that the technique is painting using electrostatic technology.

Electrostatic painting is an industrial painting technique that involves creating an electrostatic charge to propel paint particles toward a conductive metal surface. The major advantage of electrostatic painting is that paint particles can easily wrap around really difficult to paint shapes. Since electrostatic painting reduces the amount of overspray in the air, some think that this is the best way to go about exterior spray painting. Electrostatic painting isn’t necessary when it comes to exterior painting— especially with our products and technique. Source

Major industry today many use electrostatic technique in the process of painting or coating. Including the car industry. Why car industry using electrostatic technique in painting process? This is because the painting technique can be done very quickly. The result of painting is also very flat where the level of cat painting is very controlled. More importantly this painting technique can be done by robots so it is very effective and efficient. The most amazing thing is the accuracy of the amount of the paint that is not excessive so that this technique is very economical.

The geometry of the workpiece is limited only by the size of the paint booth or tank. Using electrostatic coating, it is possible to apply paint in various thicknesses being limited only by the paints tendency to run and therefore ruin the coating if applied in too thick a manner. It is usually preferred to apply many thin coats as opposed to one thick coat. Source

In physics the principle of painting using electrostatic technology is exactly the same as the tensile force between positive charge and negative charge on the electrostatic force. The sprayers used in this technique use the air to push the material or paint coating particles. By providing high voltage on the tip of the sprayer will produce a large amount of electric charge. The charged particles will come out of the nozzle after the particle binds part of the charge. Therefore, the object to be painted is generally made of metal and given opposite electrical charges so that the charge will spread evenly on the metal surface. Furthermore, the charge will attract particles with opposite charges and will move to the painted object. Due to the uniform distribution of the charge on the metal surface, the coating particles or paint materials will the coat the material evenly. Finally obtained the results of a flat car painting.
