Binders and hardeners are supplied by means of a gaseous carrier medium, such as air, to a space in front of the nozzle head. This can lead to nozzle clogging of the multi-part nozzle arrangement, which lead to a non-uniform outflow, whereby adhesion of the fibers to each other or to a wall is impaired, and make complicated cleaning work required.
  • compositions of water-redispersible polymer powder compositions e.g. B. for the production of building adhesives or as a binder for coating materials come into consideration, from DE 197 33 166 A1 (disclosure: 04.02.1999) of Wacker-Chemie GmbH.

  • the material is conveyed further in a rotor-stator arrangement, wherein the rotor in the cylindrical stator has cells which are formed by limiting blades with sealing tongues.
  • the rotor should hereby have the task of displacing the particles into an air stream at the bottom of the stator, which subsequently carries the particles out of a cell in order to produce the insulation wool mat on a conveyor belt.

Abstract

L'invention concerne un procédé et un dispositif (2) qui permettent d'appliquer un revêtement de surface sans joint sur des éléments d'édifices. Un flux de matériau de revêtement de surface (37, 92) et d'adhésif (94, 95) est pulvérisé sur un plan sous-jacent qui est situé au niveau de l'élément d'édifice. Le matériau de revêtement de surface forme une isolation pour l'élément d'édifice. On utilise un granulat pour le matériau de revêtement de surface (92). Le granulat est enrobé d'adhésif (94) et parvient, en étant porté par de l'air, sur une surface à recouvrir. Le granulat adhère instantanément par le biais de l'agent adhésif qui réagit en chaîne. Le dispositif (2) permet de produire un granulat à partir d'un réservoir de granulat (8) et un adhésif à partir d'un réservoir d'adhésif (46) et les amène conjointement réunis par le biais d'une buse (60) dans un espace rempli d'air pour former le revêtement de surface. Un dispositif de peignage (16) est utilisé pour séparer des particules de granulat (92) qui entre dans un conduit d'écoulement (28) par une goulotte (24). Dans le conduit d'écoulement, les particules de granulat sont reçues par un flux d'air (36) provenant d'un ventilateur (30) et sont amenées à l'espace rempli d'air.
