Abstract

1422262 Electrostatic spraying H J SCHAAD 23 Jan 1973 [25 Jan 1972] 3289/73 Heading B2F Apparatus for electrostatic spraying plastics material powder e.g. epoxide resin, comprises a valve-controlled compressed air inlet 4, a powder supply inlet 8, a mixing section 2, and a jet 1 comprising a converging-diverging nozzle 1b, and a spray conduit 1a, the powder flowing through the apparatus being charged by friction. At least the nozzle 1b of the apparatus is composed of a material selected from P.T.F.E., polytrifluoromonochloroethylene, quartz glass, amber, mica and aluminium oxide. An earthed metallic sleeve 3 surrounds a portion of the jet 1 to prevent spark generation. The apparatus may take the form of a pistol with an attached powder hopper 9, Figure 2 (not shown), or with a powder supply detached from the piston (Figure 3 not shown). The jet 1 is such that the powder/air mixture can flow therethrough at supersonic speeds. The discharge end of the jet pipe is provided with a diverging diffuser 7 and may also be provided with a deflector (12) or a rotary distributer 10.
