Embodiment Construction

[0042] The present invention employs a vortex fuel-oxygen mixer, among other innovations, to provide a portable flame thermal spray gun with up to 100% coating material deposition efficiency. It is simple and convenient to use in the field, and gives the user great flexibility in applying, for example, a solid smooth surface coating, or a porous, or rough surface coating, for any particular polymer coating of any desired thickness. layer material.

[0043] Thermally applied polymer and powder coating spray systems include spray guns, and unique embodiments include new and unique powder feeders and regulated and controlled supplies of air, oxygen, and propane. The polymer material to be coated is placed in a powder feeder such that the feed rate of the material is controlled by the feed rate venturi, and the polymer material is guided within the feeder by the material delivery venturi so that The raw material to be applied is directed to the spray gun where the polymeric mater...

Abstract

A system for thermal spray coating of a particulate material onto a substrate includes a spray gun apparatus having dual vortex chambers for the mixing of fuel gas and oxygen. The apparatus provides a jet flame resulting from a compression wave formed by compressed air. Dual venturis control the flow of fluidized coating material particles to provide smooth and controlled delivery of coating material to the spray gun.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority of U.S. Application No. 10 / 909,115, filed July 30, 2004, which claims the benefit of priority of U.S. Provisional Application No. 60 / 509,948, filed October 9, 2003, It is hereby incorporated by reference. technical field [0003] This invention relates to apparatus for thermal spraying, and in particular to a portable thermal spray gun for applying polymer-containing coating materials to substrates. Background technique [0004] The term "thermal spraying" refers to a process in which a feedstock of coating material is heated and propelled as individual droplets, or particles, lie on the surface of a substrate. By using a combustible gas or an electric arc, the coating material is heated by an applicator (such as a thermal spray gun) and transformed into molten, or plastic, droplets or particles which are forced out of the spray gun under the action of compressed gas. W...
