Electrostatic powder coating
Electrostatic field painting is a manufacturing process that uses charged particles to paint a particulate piece more efficiently. The paint in the form of powder or atomized liquid is initially designed to a conductive workpiece using normal spray methods, and is then accelerated to the workpiece with a strong electrostatic charge.
An addition to the electrostatic coating process is the sinking of the conductive piece into a paint tank which is then electrostatically charged. The ionic bonding of the paint with the metal creates the paint layer, in which its thickness is directly proportional to the length of time the parts are left in the tank.
After the pieces are extracted from the paint tank, they are rinsed to remove any residual paint that is not ionically bonded, leaving a thin film of electrostatically bonded paint on the surface of the piece.
To ensure good adhesion to the surface, it is recommended to check it before application to ensure it does not show any traces of: lubricants, oil, wax, rust or other contaminants. Otherwise, the paint will not provide adequate surface protection, resulting in premature corrosion and low adhesion. A thorough cleaning of the application area is recommended. For increased corrosion resistance, chemical surface treatment is recommended, eg chromating or equivalent for aluminum and phosphating for steel.
The surface preparation shall be continued according to the following versions:
