Abstract (en)
[origin: EP0123967A1] The wall of a powder spraying booth intended to the pulverent coating of work-pieces is comprised of profiled metal plate elements (17, 172) connected to earth connections (21) so that the booth acts has an earthing cage. On the inner sides of the booth there are arranged, by means of an adhering layer (23) based on insulating glue, separated sheets or plates (31), which are also based on electrically insulating glue, which touch each other and which, optionally, also touch the hollow moulding flanges (34) based on insulating glue to be installed in the corners, which are connected by welds (36) or glued so as to form a smooth surface. Thereby, the whole inner side of the booth is configured so as to present a smooth surface without curves, thereby facilitating the cleaning and, owing to the insulation with respect to the earthed outer booth part, the inner side is charged to the same polarity by the spraying powder. The powder which approaches the booth wall is pushed back by electrostatic forces before adhering. Thereby, deposits on the booth wall are substantially reduced.
