Abstract (en)

[origin: WO9108056A1] In the process of the invention, multi-component resins are applied to porous, granular materials intended for subsequent consolidation. Application is carried out by feeding the components, physically separated from each other, under relatively high pressure, to a mixing chamber, mixing them by turbulent means in the mixing chamber, and applying the resulting mixture, at relatively low pressure, as a thin curtain in laminar flow to the material. The simplest form of the device of the invention comprises: a) separate feed lines for the components at relatively high pressure; b) a mixing chamber preferably designed as a static mixer; c) a fan spray nozzle working at relatively low pressure. The process and device are used to increase the sound-absorption and/or ease-of-cleaning characteristics of a railway track, to increase the cross-sliding resistance of railway sleepers on ballast, and to smooth the transition between a soft and hard railway track.
