What is an electrostatic image?
Electrostatic painting, also referred to as a powder coating, is an innovative method used for painting metals and certain types of plastic. It uses electrically charged powders to create an elegant and smooth surface and other desired effects. The electrostatic field is responsible for allowing the powder coating to allow.
The electrostatic field is a phenomenon that resembles a typical magnetic field. For example, when a certain object becomes electrically charged, it automatically creates an electrostatic field. If this object has an excess in the number of electrons, then it is considered a negative charge. However, if the object had less electrons than its external environment, an object is considered a positively charged object.
As with magnetic fields, two electrostatic objects with the opposite charged particles are automatically attracted. This is the basic idea of electrostatic painting that uses this electrostatic forest to faster and more efficiently painting metal objects. Cleaning is also ChristmasEC. Special tools are required for electrostatic painting. The tools must be used to use the attractions of charged fields. The electrostatic image setting is a bit more complicated than the setting for standard painting, but the process is simple.
The first step of the process involves mixing the formulated color with a chemical catalyst to create a positive charge. The metal object that needs to be painted will then be grounded by the connected connection. Because the metal object and the formulated color hold the contradictory charge- the color is positive, while the metal is negative- the color easily attracts to the metal object.
After the charging and settings are complete, the image can take place. Positive charge color is sprayed with a petition and easy to catch on the surface of the metal. The attraction of contradictory fees is so strong that even if only one side of the metal pole is sprayed, the charge automatically draws the color of the bikeM of metal and covers its entire surface.
The metal is then baked in furnaces with temperatures up to 500 ° F to achieve a hard surface. The electrostatic image provides a very durable coating system for aluminum, architectural steel, racing car frames, terrace furniture, registration cabinets, doors and window frames. The method can usually achieve a smooth mirror surface without running, SAG, bubbles and drops, which usually occur with traditional liquid painting methods.
Color also generally proved to be more resistant than other liquid colors plus. In addition, this process is an ecological process because it does not use any solvents that can evaporate or contaminate drainage water. However, the electrostatic image can produce unpleasant odors and it is recommended that the painting should be carried out outside.
