Electrostatic Powder Coating.

摘要

The distribution of a liquid in an even, thin protective layer over a surface has for many years been the method adopted for either protecting the substrate and/or enhancing its appearance. Distribution of the coating, or paint, is usually effected by one of three ways: brush, roller or spraying. Liquid paint is widely used in manufacturing industries where invariably some type of coating is deposited on the finished product. Distribution of the paint by atomization into a fine aerosol lends itself very well to substrate coating, and numerous commercial coating systems are available. Some systems use air atomization while others adopt centrifugal forces for disruption of the continuous phase liquid into fine droplets. jg p.12.
