  • One-component systems contain an integrated network system and are like that procure that they are in active form under compliance with specified requirements can be stored.
  • the matrix is linked by chemical or physical processes triggered.
  • Exemplified for the A large number of crosslinking options are the oxidation reactions via the Atmospheric oxygen or the vulcanization of one-component silicone sealants about the humidity.
  • a one-component foam is typically after 15 minutes tack-free, cut after about three hours and after about eight hours fully cured. These curing times are general for the construction industry too long.
  • a precursor of the polymer (the so-called “Prepolymer”; first component) immediately before use with a low one Amount of a chemical additive added (the so-called “hardener”; second Component), whereby the hardening process by polymerization and crosslinking is triggered (activation).
  • the proportion of hardener added is about 4 to 10% by volume of the prepolymer.
  • the networking times can be extremely limited be independent of chemical influences in the atmosphere that trigger the chemical reactions.
  • the chemical activity of the Networking can be controlled via the individual components that are mixed together are.
  • Multi-component systems require that the individual Components are packed separately and mixed homogeneously on site. In addition, they have to be processed in a given time, because with the Introduction of the active component (mostly cross-linking system) of the vulcanization process - so these systems already react at room temperature - is initiated and can no longer be stopped.
  • the components must be in one predetermined ratio are mixed, which is almost always the ideal case Deviates 1: 1.
  • the device comprises an opening Outer container for receiving the first fluid component and one inside the Outer container arranged, an inner container having a mouth for receiving the second fluid component.
  • the device and the method are characterized by a tension element, which through the opening of the outer container guided and sealed in it is movable and which one inside the Has outer container lying outer boundary surface on the mouth of the inner container is attached so that it moves when the tension element is taken from the boundary surface, as well as one inside the Outer container between the mouth of the inner container and the opening of the Outer container arranged stop element with a stop surface on the abuts the mouth during an outward movement of the tension element, so that the boundary surface of the Mouth can be deducted.
  • the object of the invention is to overcome the disadvantages described above overcome and provide means by which the components of a Polymer material mixed easily and without cumbersome handling and can be homogenized.
  • One aspect of this task is the broad one Avoidance of empties to be used only once.
  • the invention is based on the surprising finding that it is relatively simple mixing device, which has the shape of a spiral, which is possible in a cartridge provided with a first fluid component with one or more second fluid components to mix so that a homogeneous mixture arises.
  • the invention therefore relates to a device for mixing or Homogenize at least two fluid components, including one for Recording of the first fluid component serving cylindrical cartridge that one side is used to promote the mixed fluid components displaceable piston carries, and further comprising a mixing device.
  • the cartridge has a removable on the other side Lid
  • the mixing device has the shape of a spiral, which after removal of the lid in the - then open - insertable and rotatable therein.

  • the spiral mixing device is inserted into the cartridge and rotated.
  • the spiral must be turned in the direction that would be used to screw a screw into the material, the screw being formed by the spiral (hereinafter referred to as the "conveying direction" designated).
  • a material flow then arises in the direction of the opposite one Side of the cartridge, which is closed with the sliding piston.
  • the conveying effect of the spiral which is like, is responsible for the material flow a screw turns forward. This constantly changes the point of contact the spiral with the inner wall of the cartridge and pushes the material in Wall area in the screw direction.
  • Another surprising result of the device according to the invention is therein to see that the mixture obtained is completely free of air bubbles.
  • the promotional effect the spiral does not only effect the homogenization of the material, but also also its ventilation.
  • the device according to the invention is simple, fast, uncomplicated and everywhere use, i.e. in construction as well as in technical sealing work. Since the spiral mixing device is used again after cleaning , it does not represent any further empties that are only used once can. Only the empty cartridges have to be disposed of after the application of the Materials.
  • Another advantage of the device according to the invention is that in addition to the hardener component, any number of other components mixed air-free and can be homogenized, for example color pastes, catalysts or Fungicides.
  • the spiral is dimensioned so that it is close to the inner surface of the cartridges is present. This leads to an increase in the screw-like conveying effect of the Spiral and shortens the mixing or homogenization times.
  • close fitting is a minus tolerance or a game of the spiral against the Understand the inner surface of the cartridge from 1 to 1.5 mm, i.e. the outside diameter the spiral is smaller by this dimension than the inside diameter of the Cartridge.
  • a material with a projected circular cross section is preferred for the spiral.
  • the spiral itself preferably has a slope in the range from 30 to 110 mm.
  • Material is suitable for steel, with stainless steel being preferred.
