Abstract: A composite material, particularly useful for prestressing concrete and in stay cables for cable-stayed bridges and other such uses where strength, corrosion resistance and resistance to fatigue failure are particularly important, comprises high strength wire strand coated and impregnated with an impermeable and strongly adherent epoxy based resin. The impregnated and coated epoxy increases the flexural stiffness of the composite against bending fatigue in the areas of the anchorages in dynamically loaded situations and reduces relative movement and rubbing of the wires of the strand so as to reduce fretting and hence fretting fatigue, the principal mechanism for failure in dynamically loaded strand. Impregnation and coating are effected by passing the fully formed and heated strand through a known electrostatic powder coating line, modified to include a mechanism for temporarily opening successive sections of the strand such that the strand passes into the coater in an opened state, and the strand wires are coated with a fused thermosetting epoxy resin before the strand is permitted to reclose, the resin filling the interstices in the reclosed strand. The strand opening mechanism includes a rotatable template with wire guides for leading the outer spiraled wires temporarily away from the center wire, and can be used in any method where a formed strand or similar member needs to be opened for coating or otherwise surface treating the interior wire surfaces in a continuous process.

Abstract: A method and apparatus is provided for removing electrostatically bonded powder coating material from a non-recessed region of a surface of a workpiece without removing powder coating material from a recessed region of the surface of the workpiece. The present invention employs a powder coating removal apparatus for removing the powder coating material from the non-recessed region. The powder coating removal apparatus comprises a rotatable drum including a hollow cylindrical portion having a plurality of openings therein. A plurality of elastic bands are connected to opposite end portions of the drum and serve to frictionally engage and agitate the powder coating material on the non-recessed region of the surface, thereby overcoming the electrostatic bond between the non-recessed region and the powder coating material thereon. A vacuum hose is placed adjacent to one, open end portion of the drum and serves to create a vacuum in the hollow cylindrical portion of the drum to remove the agitate powder coating material from the non-recessed region of the surface of the workpiece.

Abstract: A method for applying a sequence of protective coatings to steel parts includes the steps of depositing a zinc coating, a chromate coating and a synthetic resin coating. The parts to be coated are supported on a hanger and carried thoughout the entire coating operation by a continous conveyer system. The zinc coating is electrolytically deposited from an alkaline non-cyanide electroplating bath to a thickness of from 0.05 to 0.2 mils. The zinc-coated parts are washed, and while still wet, are sprayed with an aqueous chromating solution. After rinsing and drying, a synthetic resin coating is applied to the chromate-coated parts by electrostatic powder spraying. The parts are then baked in an oven to fuse the resin coating. The method is particularly applicable to refrigerator racks.

Abstract: In a powder coating facility wherein powder entrained with conditioned air sprayed from a feed conduit (11) to a workpiece, such as a can body (51), and excess powder is returned by suction by means of exhausts (29, 25), a conditioning chamber (21) is arranged around the coating zone (15) in order to prevent contamination of the dispensed powder due to influences of the enviroment (U). An air flow (S) is provided, produced from openings (23) of the chamber (21), to conduct the can bodies (51) into and through the chamber (21). The air flow from the openings of the chamber prevents influences of the ambient surroundings of the chamber powder sprayed and retrieved in the powder coating facility.
