Definitions

  • the present invention relates to a flexible device having fire-resistant properties.
  • This device aims to ensure the protection of elements, devices or apparatus against propagation of heat in case of fires.
  • This device is intended for example to provide protection of electric cables in a cable tray, in case of elevation of heat due for example to a fire. It is indeed essential, in numerous installations, to be able to protect electrical cables and other control cables during a fire, as long as these are linked to fundamental security systems.
  • the device according to the invention is a flexible device, in order to be able to marry as best as possible the areas to be protected.
  • These measures contains several components, in particular at least one layer fibrous elements consisting for example of ceramic wool, optionally at least one protective fabric, with assembly of different components with glue or intermediate sealant.
  • Known devices can incorporate water molecules which, by vaporizing under the action of heat, absorb energy and delay the propagation of the temperature rise from the face of the device turned from the side of the fire towards the cold side of the latter.
  • the properties firewalls are not stable over time, due in particular to the natural dehydration of the device, linked to the environment, in particular the warm atmosphere of certain premises or facilities, such as nuclear reactors, boilers or refineries. In these conditions, there is a gradual loss of water from the protection device, limiting the effectiveness of it.
  • substrates such as ceramic fibers
  • substrates are obtained by fusion at very high temperature, of the order of 2000 to 2300 ° C, which prohibits the natural presence of water in any form whether it be.
  • French patent 2,701,850 in the name of the Applicant, relates to a device of this type, in which the assembly of the different elements, such as fibrous and / or textile elements, is produced using a refractory adhesive containing active components and / or additives containing chemically bound water, and stable at temperatures below 80 ° C.
  • the advantage of using chemically bound water is that the water molecules are not free, and cannot therefore evaporate under the action of a normal rise in temperature, the only possibility evaporation occurring during a significant rise in temperature accompanied by decomposition of molecules containing chemically bound water.
  • the glue also contains unbound water chemically and which, for its part, will evaporate as the product aging.
  • the object of the invention is to provide a flexible device having fire-resistant properties, which has a reduced thickness, and the stability over time is even better.
  • the device which it relates to of the type comprising a complex of fibrous and / or textile and / or grid-like elements is characterized in that inside at least one of the constituent elements of the complex are inserted dry particles of products containing molecules that are chemically and physically stable to ambient temperatures, and which generate an endothermic reaction during a rise in temperature.
  • the molecules generating an endothermic reaction are dispersed in the mass of at least one of the constituent elements of the complex, without having been previously placed in an aqueous solution. These molecules are in the form of a powder, the particles are placed directly in at least one of the elements constitutive of the complex, without being associated with an aqueous support, which dehydrates as you age. The stability of the device is therefore guaranteed, without no loss of efficiency over time.
  • this device comprises several types of molecules generating an endothermic reaction, ensuring retention of water at different temperature levels, up to temperatures higher than 200 ° C.
  • This characteristic makes it possible to benefit from reactions endothermic at different temperatures, which promotes delay of the heat transmission from the hot side to the cold side of the device.
  • the molecules generating a endothermic reaction are arranged between the different layers of the building blocks of the complex.
  • the molecules generating an endothermic reaction are inserted into the openings corresponding to the mesh of the element.
  • the molecules generating a reaction endothermic are inserted in the thickness of the sheet, between the fibers.
  • Needling a sheet of fibers for example fibers of ceramic, also reduces the thickness of this layer, which constitutes an advantage, insofar as the device is intended for wrap elements of complex shape, not allowing a material thickness too great. According to one possibility, in the case where it has several layers of superimposed fibers, the operation needling is carried out at the same time through the different layers fiber.
  • the molecules generating an endothermic reaction contain bound water chemically.
  • the molecules containing chemically bound water are chosen from hydrates of metal or metalloid oxides, such as hydrated alumina Al 2 O 3 , 3 H 2 O.
  • the molecules generating an endothermic reaction consist of heavy metals, such than lead or mercury.
  • some at less of the components of the complex are assembled with an adhesive refractory itself containing molecules of chemically bound water.
  • the amount of glue used for the assembly of several building blocks of the complex may be less than that implemented in patent 2,701,850, while benefiting from a better stability over time and superior fire-resistant properties.
  • Figure 1 shows two cable trays 2, serving each guiding and supporting a certain number of cables 3. These two superimposed cable trays are surrounded by a fire protection, capable of withstanding for 1 H 30 min a fire, without damage to cables.
  • This device has faces interior and exterior covered with a fabric 4.
  • This fabric is, for example, a glass cloth, the outer faces of which have been coated with silicone.
  • Each layer of fibrous elements consists, for example, of soluble and amorphous artificial fibers of alkaline earth silicate.
  • the thickness of each layer 5 is of the order of 35 to 40 mm, and its density is close to 130 kg per m 3 .
  • the different layers of fibrous elements 5 and of fabric 4 are assembled to each other by a refractory adhesive 6 comprising elements containing chemically bound water, stable at temperatures below 80 ° C. This glue holds up to approximately 1300 ° C.
  • each layer 5 of fibrous elements contains molecules in its thickness 7 stable at temperatures below about 80 ° C., comprising chemically bound water, chosen from metal oxide hydrates.
  • FIG. 3 represents a layer 5 of fibrous elements during carrying out the insertion of the particles 7, by a needling technique, using a frame 8 driven by an alternating movement and equipped with a set of needles 9.
  • Figure 4 represents the evolution of the temperature on the side of the cold side of three fire protection devices subjected to the same warming up.
  • the three curves were established taking into account the ISO834 standard.
  • Curve A represents the evolution of the temperature in function of time, in the case of two fibrous layers, such as layers 5 defined above, simply placed one on top of the other, without bonding.
  • Curve B represents the evolution of the temperature in function of time, in the case where the same two layers are glued by an adhesive containing elements containing chemically bound water.
  • Curve C represents the evolution of the temperature in function of time, in the case where the two layers contain, distributed in their thickness, molecules 7, comprising bound water chemically, the two layers 5 then having a thickness equal to three quarters of the thickness of the layers of those used for the establishment of curve B, and being glued to each other using of an adhesive identical to that used previously but whose quantity is halved. Despite the decrease in the amount of glue and the reduction in thickness of the layers of fibrous materials, the performance is significantly improved since the fire resistance is much longer.
  • the invention provides a great improvement to the existing technique by providing a device flexible with fire-resistant properties, of simple structure, the performances are high, and whose stability over time is excellent.
  • the invention is not limited to the single form of this device, described above by way of example, it on the contrary embraces all variants. This is how the number of layers of fibrous elements could be different, than the complex could contain other molecules generating a reaction endothermic, such as mercury or lead, that the device may not include protective fabric, or may contain other elements intermediaries, such as a grid structure element, without this goes beyond the scope of the invention, as defined in the claims.
