    摘要: In a process for applying a friction-resistant coating to a steel sucker rod, the rod is passed, in sequence, through a surface preparation stage (for example, scale removal, shot peening, or other suitable method), an adhesive application stage (to enhance the strength of the coating's bond to the rod), an extrusion stage (in which the rod is passed through a die in conjunction with a flow of melted polymeric coating material), and a cooling (coating solidification) stage. Typically, the radial thickness of the coating will be between 0.125 and 0.375 inches. The process is adaptable to apply extruded coatings to continuous rod or to individual sucker rods having upset ends. The coating may be selected from but is not limited to high-density polyethylene, cross-linked polyethylene, polyvinylidene fluoride, ethylene tetrafluoroethylene, polytetrafluoroethylene, polyphenylensulfide, nylon, polyester, polyethersulfone, polyethylene terephthalate, polypropylene, polystyrene, epoxy, or acetyl.

    摘要: A cooling apparatus for cooling objects from a painting device is disclosed. The cooling apparatus comprises a housing enclosing a cooling zone, a transport device for transporting workpieces through the cooling apparatus along a transport direction from an entry region through the cooling zone and through an exit region. A heat exchanger is configured for cooling air from the cooling zone and to redirect cooled air into the cooling zone.

    摘要: A method of making a screw threaded fastener (1, 10) for fixing cladding to a building includes the steps of applying a mastic covering (5, 15) to a screw threaded portion (4, 13) of the fastener, and applying a non-sticky protective coating (6, 16) to the outside of the mastic covering (5, 15) so as to prevent the fasteners (1, 10) from sticking together during handling and packaging of the same. Preferably the protective coating (6, 16) is as coating of a waxy substance and is applied to the outside of the mastic covering (5, 15) by means of a dipping or spraying process or operation. The fasteners are then easy to use and form a water-tight, moisture and vapor-proof seal with respect to their supports or substrates. The waxy coating (16) may also be applied to the drill point (12) so as to act as a lubricant during driving of the fastener.
