Abstract

970,308. Mixing liquids in proportions; spray-producers ; coating apparatus. SCHERING A.G. Sept. 26, 1961 [Oct. 5, 1960 ; April 22, 1961], No. 34482/61. Headings B1C, B2B and B2F. In a process and apparatus for the application of two-component resins, the components are metered by pumps, heated separately to 40-200 ‹C. and passed to an application device (which may be a two-component spray gun or a mixing chamber with delivery nozzle). The apparatus, Fig. 1, comprises two metering pumps 1 driven by a motor 3, supplying the components separately to a heat exchanger 4 where they are raised to a temperature preferably of 100-110 ‹C., and thence to a twocomponent spray gun or mixing chamber. The heat exchanger 4 is oil filled and heated by a thermostatically controlled immersion heater 7. The spray gun, Fig. 4, is supplied with the resin components and air through a heated hose 5, the air being pre-heated in the heat exchanger 4 and raised to 70-80 ‹C. by the heater 10. The gun has a suction hood 24 for withdrawal of resin fume through a hose 18 by a fan 14, Fig. 1. Oil from the heat exchanger is used to heat the hose 5, which contains pipes 19 for the resin components 20 for the heating oil, and 21, 22 for air respectively for controlling the spray gun and for spraying, see Fig. 5. Alternatively the components may be supplied to a mixer, Fig. 6, comprising a cylindrical chamber having inlets 37, 38 and a sheet-metal stirrer 30 driven through a detachable coupling 32 by an air motor 26 the discharged air from which may be used for cooling. Owing to the shape of the stirrer the mixture takes a spiral path through the screen 39 to the outlet 36 to which may be attached a single component spray gun, or nozzles suitably shaped for casting, injection or coating.
