  • the temperature of the fire protection unit for a certain time does not increase or only slightly, so that the period of time within which the fire protection unit is effective, can be increased.
  • the effectiveness of the planar fire protection unit can be further increased by the fact that the means which performs an aggregate state change has a preferably high heat capacity. It is advantageous if the support structure is formed from a material which has a low thermal conductivity. This reduces the heat transfer into the medium. The effectiveness of the fire protection unit is thereby increased.
  • the agent may be in solid, for example in granular form. There is also the possibility that the agent is a liquid or a pasty liquid. If necessary, the agent will be available bound. This can preferably be achieved by the means used together with absorbers.
  • the absorbers may be organic or inorganic absorbers.
  • the support structure is at least partially surrounded by a vapor barrier. This ensures that the agent, which evaporates, for example, under the action of heat, remains longer in the support structure.
  • the provision of the vapor barrier has the advantage that in this way an improved posture of the fire protection unit is achieved.
  • the vapor barrier is preferably one which is at least partially formed by a film.
  • vapor barrier substantially hermetically seals the support structure from the environment.
  • the support structure can also be designed such that it has chambers which are separated from one another by preferably flexible webs.

  • the schematic in the FIG. 1 shown fire protection unit can be prepared, for example, characterized in that first the porous support structure 2 is provided.
  • the means 4 is introduced.
  • the introduction of the agent can take place, for example, by that the support structure 2 is immersed in, for example, a bath with the agent.
  • the means can also be introduced by means of at least one roller or a similar device in the support structure.
  • the agent is applied to the support structure.
  • the excess agent is removed from the surface of the support structure.
  • the support structure is introduced with the means in a film in which the support structure is preferably hermetically sealed.
  • the structure is placed under vacuum during manufacture, so that the film rests close to the surface of the support structure.
  • the vacuum is installed so that the fire protection unit maintains flexibility.
  • the necessary opening for introducing the vacuum is then welded or glued.
  • FIG. 2 schematically a flat, flexible fire protection unit 1 is shown in a front view.
  • the fire protection unit 1 has a support structure 2, which has a plurality of chambers 3.
  • a means 4 is arranged in each case, which performs at least one state of aggregate change under the action of heat.
  • the support structure 2 is formed by films 5, 6 and 8.
  • the films 5, 6 and 8 are spaced from each other.
  • the films 5, 8 are interconnected by means of webs 7.
  • the films 6, 8 are interconnected by webs 9. They each form chambers 3, 10, which extend in the illustrated embodiment substantially parallel to each other.
  • the webs 7, 9 may be formed offset from each other, so that the chambers 3, 10 partially overlap.
  • the means 4, which is arranged in the chambers 3, 10, is preferably such an agent, which has an absorber, which is loaded with a liquid.
  • the absorber may be an organic or inorganic absorber.
  • the films 5, 6 are preferably semipermeable, so that the liquid optionally bound in the chambers can escape from the fire protection unit 1 through the foils 5, 6 after an aggregate change in the form of vapor.
  • FIG. 4 schematically a device for Abschotten a room against a flowing in the room or from the space fluid is shown.

  • the inventive design of the device for Abschotten a room against a flowing into the room or from space fluid, in particular a combustible liquid is achieved that the fire protection unit 1 on the one hand causes a liquid-tight barrier of a passage 13, so that the liquid is not can flow into the room or into a room. Because of that Fire protection unit has a means which performs at least one state of aggregate change under heat, it is achieved that the liquid-tight film is protected. A decomposition of the film by heat is substantially avoided.
  • FIG. 5 is shown schematically the temperature profile over time. The time is given in minutes.
  • FIG. 5 shows the temperature profile within a furnace.
