Definitions

  • the invention relates to a method for producing a double-walled container by creating an additional container wall made of glass fiber reinforced plastic along an already existing container wall on a cavity former.
  • the void former is an aluminum foil which has knobs projecting towards one side. With these knobs, the cavity former is supported against an epoxy layer applied to the inside of a container wall.
  • the aluminum foil has a glass fiber laminate layer on its side facing away from the knobs and the container wall. The aluminum foil with its glass fiber laminate layer and the knobs is applied to the epoxy layer overall in the form of sheets.
  • the known method is relatively labor-intensive and does not lead to any significant increase in the stability of the container, since the wall formed in it only touches a thin synthetic resin layer applied to the inner wall of the container with its aluminum knobs.
  • the wall formed in it only touches a thin synthetic resin layer applied to the inner wall of the container with its aluminum knobs.
  • the invention is based on the problem of developing a method of the type mentioned at the outset with which single-shell containers can be converted as easily as possible into double-shell containers of high strength.
  • the void former consists of two cover weave layers which are connected to one another by web threads running at right angles to the plane of the cover weave layers.
  • Such a cavity former can be laminated into synthetic resin just as easily as a glass fiber mat. Due to the usually rolled-up synthetic resin, the web threads stand up when they are laminated in and ensure that a cavity is created between the cover layers, which enables a free flow of liquid on all sides. Therefore, liquid that enters the cavity as a result of a leak can directly reach a liquid sensor, so that a leak warning is triggered reliably and quickly.
  • the void former used for the method according to the invention is known per se. So far, however, it has been used to increase the thickness of a layer in order to increase its thermal insulation capacity and its strength.
  • the method according to the invention can be carried out particularly reliably and quickly if the void former consists of E-glass filament fibers.
  • the container wall is first provided with a layer of glass fiber mats laminated in synthetic resin and the cavity former is applied thereon, and if further glass fiber mats are then laminated onto the cavity former.
  • Such a training has the additional advantage that the interior of the container is also protected against the ingress of water through the concrete wall.
  • liquid sensors with a small thickness are used, then this can be done by creating slots for inserting liquid sensors of a leak detection system after the cavitation agent has been applied to a container bottom in the cavitation generator.
  • a synthetic resin mortar layer can be applied to a container base as a cavity former with liquid sensors embedded therein and only the container walls with the one consisting of two cover weave layers and provide the spacer for the web threads.
  • Spark formation due to electrostatic charges can be excluded in a manner known per se by integrating at least one electrically conductive layer into the container wall applied.
  • the invention permits numerous embodiments. To further clarify its basic principle, a section through a section of a wall of a container is shown schematically in the drawing.
  • the wall shown consists of an originally existing container wall 1 made of concrete.
  • a base layer 2 is first applied to this container wall.
  • This consists, for example, of an adhesive bridge with alkali-resistant epoxy resin, two layers of glass fiber stacking mats laminated in polyester resin and a carbon fiber fleece with an electrical conductivity of 105 ohms.
  • a cavitation agent 3 in polyester resin is placed on this base layer 2 and consists of two cover weave layers formed from E-glass filament fibers, which are connected to one another by web threads.
  • This cavity former 3 can be delivered compressed flat. Its web threads stand up when laminating in, so that the required cavity is then created.
  • an outer layer 4 which, for example, consists of five layers of glass fiber stacked binder mats laminated in polyester resin, a carbon fiber fleece and a surface seal with top coat.
