Title: Improvements relating to the coating of surfaces with polytetrafluoroethylene
IPC: B05C19/02
Filed: 1964-11-06
Abstract: 1,134,181. PTFE coatings; coating apparatus; spray producers. SEALECTRO Ltd. and S. T. DEAKIN. 4 Nov., 1965 [6 Nov., 1964], No. 45370/64. Headings B2E, B2F. B2K and B2L. A method of coating a surface with polytetrafluoroethylene comprises the step of projecting PTFE particles, which may be of substantially uniform size, through a heating zone e.g. a tubular heating element, wherein the particles are heated to sintering temperature by means of infra-red radiation, and on to the surface to be coated, and on which surface the hot particles coalesce. The particles may be projected in a gas stream, the particles, but not the gas, being heated to sintering temperature and the surface to be coated being at a temperature below the sintering temperature of the PTFE particles. The particles may be projected (1) by blowing a stream of gas e.g. nitrogen, argon or air, through a bed or mass of the particles; or (2) by feeding the particles by mechanical means e.g. a screw feed or a rotatable cylindrical member provided on its cylindrical surface with a number of grooves to which powdered PTFE is fed and a duct for gas which crosses the surface of the cylinder and is arranged so that a portion of the member enters the duct and the gas picks up PTFE particles lodged in the grooves, into a stream of gas passing to the heating zone. The particles may be pre-sintered before being fed to the heating zone. The particles may have been prepared by compressing PTFE, sintering the compressed particles to form a coherent body and then grinding the body to form fresh particles. The particles may comprise pigmented PTFE, the pigment having sufficient thermal stability to withstand the temperature of the heating zone. The surface to be coated may be degreased, etched or sandblasted before being coated. Apparatus for coating a surface comprises means for feeding PTFE particles into a gas stream, means for passing the particles in the gas stream into one end of a tube, which tube is surrounded along a substantial portion of its length by an infra-red heating means which heats the particles so that they sinter, the tube being arranged so that the sintered particles pass out of the other end of the tube on to the surface to be coated. The means for feeding the PTFE particles into the gas stream may comprise means for directing a stream of gas e.g. air, onto or through a bed of PTFE particles supported at one end of the tube; or a rotatable cylindrical member provided on its cylindrical surface with a number of grooves, means for feeding PTFE powder to the surface of the cylindrical member so that the grooves pick up powder when the member rotates, and a duct for conveying gas, which duct crosses the cylindrical surface of the cylindrical member and is open to part of that surface so that gas passing through the duct can pick up powder from any groove which crosses its path when the cylindrical member rotates.
