Definitions

  • the present invention concerns a method for the manufacture of a mineral wool product, especially a mineral wool board in accordance with the description of Claim 1, and also concerns a mineral wool product, especially a mineral wool board, in accordance with the description of Claim 6 hereinbelow.
  • the invention relates in particular to glass wool products and their manufacture.
  • Mineral wool products especially when made of glass wool or rock wool, are mainly used for heat insulation purposes and, more particularly, the heat insulation of buildings in the area of roofs, walls and ceilings.
  • the mineral wool sheeting strips or mineral wool boards are laid between rafters or beams and, whenever necessary, attached to the rafters or beams by appropriately tacking the projecting edges of aluminium linings; alternately, they may be inserted between the rafters and beams by means of a pressure fit, in which case there is no need to fix them mechanically.
  • US 5,671,518 discloses a method for processing mineral wool mats, comprising the steps of producing fibres, providing a binder, depositing that fibres in the form of a laminar mat on a production line and crimping that laminar mat by introducing forces parallel to a surface of the laminar mat and in a direction of movement of the laminar mat before the binder hardens.
  • the invention therefore sets out to create a mineral wool product that will not give rise to cutting wastes and be characterized by a carefully balanced relationship between flexibility and flexural rigidity, the aim being, in particular, to create a method that will make it possible to set this relationship between the flexibility and the flexural rigidity in an appropriate and simple manner.
  • the mineral wool board created in this manner should be simple to handle, assure a wide range of possible uses due to the possibility of a quasi-inherent tolerance compensation and should also be particularly suitable for being fixed in the space between rafters or beams when buildings have to be insulated.
  • the invention should assure a firm seating of the mineral wool board and close contact with the adjacent rafters or beams; perfect heat insulation also requires the seating to be free of heat bridges.
  • a method for the manufacture of the mineral wool product as per the invention is characterized by the fact that, prior to being hardened, at least one section that delimits one of the two principal faces of the board or sheeting strip is subjected to a so-called crimping process, a kind of crushing respectively upsetting, in the longitudinal direction. Owing to this process the fibres in this section tend to fold and assume an up and down pattern, whereas the fibres in the adjacent section lying above it substantially retain their original orientation, i.e. the fibre orientation in this section remains essentially parallel to the two principal faces.
  • the crimping process produces a higher density in the section that has been crimped and this section will also be characterized by greater compressibility (a kind of crinkled zone), whereas the properties of the adjacent layer or section, which has not been crimped, will not have been modified and therefore remain substantially as before. This produces the desired balanced relationship between flexibility and flexural rigidity, a feature that is further facilitated by the enhanced density produced by the crimping process.
  • the crimping process can be advantageously performed by means of conveyers arranged in sequence and operated at different speeds and, more precisely, at gradually diminishing speeds.
  • a kind of rippling or goffering effect will thus be obtained at the interface between adjacent conveyers operated at different speeds, because the upstream conveyer will supply more mineral wool than is taken away by its downstream counterpart.
  • the conveyers are arranged below the mineral wool sheeting, because in that case the self-weight of the lower section of the mineral wool sheeting will subject it to the desired crimping process in a very controlled manner.
  • the speed of the fastest conveyer of the conveyer sequence it will be appropriate for the speed of the fastest conveyer of the conveyer sequence to be about 20% greater than the speed of the hardening kiln, while the speed differences between successive conveyers should be of the order of 4%.
  • the length of the carrying run of the diminishing-speed conveyer sequence can also be used as a control parameter for the crimping process. The shorter the carrying run of these conveyers, the more intensive will be the crimping process and the resulting crimping structure.
  • the thickness of the section with the crushed fibres can likewise be determined by means of an appropriate choice of the length of the conveyer belts, but also the distance between the conveyers.
  • the mineral wool product in accordance with the invention is characterized by the fact that it contains at least two sections with different fibre orientations, and it will be advantageous if one of these sections delimits one of the principal faces of the board and if the said section has a fibre structure that has been produced by means of a crimping process. It will also be advantageous for the mineral wool product to be made up of only two sections with different fibre orientations. In that case the section that has been structured by means of the crimping process can account for up to 90% of the total product thickness, but in general its thickness will not exceed one third of this total thickness. In this way the product can be given the desired finely balanced relationship between the flexibility and the desired flexural rigidity.
  • the mineral wool board 1 shown in Figure 1 is formed by cutting a certain length of mineral wool sheeting that was produced by collecting mineral wool fibres on a conveyer belt, adding a binding agent and then passing the whole through a kiln (furnace) for hardening.
  • a kiln furnace
  • the greater part of the fibres are oriented parallel to the conveyer belt surface on which they are collected and therefore parallel to the two principal faces of the sheeting.
  • the two principal faces of the mineral wool board have been assigned the numbers 2 and 3.
  • the mineral wool board 1 of the illustrated implementation example consists of two sections with different fibre alignments or orientations, namely a section 4 that delimits or constitutes the upper principal face 2 of the board 1 and a lower section 5 that delimits or constitutes the opposite principal face 3 of the board 1 . Due to the described method of producing the sheeting, the fibres in the upper section 4 are substantially parallel to the two principal face 2 and 3 .
  • the fibres in the lower section 5 are rippled and/or folded in the manner of a meandering river, a state of affairs that is obtained by means of the crimping process to be described with the help of Figure 2.
  • the fibres in the lower section 5 are no longer predominantly parallel to the principal faces of the board, the fibres being rather characterized by an up and down pattern and a limited parallel alignment, so that the structure in a certain sense can be broadly described also as a wavelike structure. Owing to this fibre pattern, the flexibility of board 1 is rather greater than that of a board in which all the fibres are substantially parallel to the principal faces.
  • section 5 will have a greater density and this, in its turn, constitutes an advantage inasmuch as it enhances the rigidity, a desired feature that facilitates handling when the mineral wool board has to be inserted or pressed into the space between rafters or beams and also has favourable effects on the contact between the board and the rafters or beams.
  • the board is therefore particularly suitable whenever the board does not have to be self-supporting in retaining its positions between the rafters or beams, but the rafters or beams have some kind of closure on their underside, wooden boarding for example, in which case the mineral wood board 1 can be inserted from above.
  • the upper section 5 which has undergone the additional crimping treatment
  • the lower section 4 which has not undergone this treatment
  • the thickness of the upper section 4 and the thickness of the lower section 5 account for roughly 50% of the total board thickness each. It should however be noted that the transition between the treated section 5 and the untreated section 4 , where the fibres have remained substantially parallel to the principal faces of the board, is gradual, i.e.
  • the passage from the rippled fibres of the treated section 5 to the parallel alignment of the fibres of the untreated section 4 is not sudden, but the rippled and more or less wavelike or up and down pattern of the fibres tends to flatten in the direction of the parallel alignment and to constitute a transition section, as has been roughly indicated in Figure 1.
  • the intensity of the crimping process can be regulated by appropriate setting of the operating parameters and the rippling of the fibres can therefore be made either more or less pronounced.
  • the mineral wool board 1 shown in Figure 1 which may in particular be made of glass wool, has a length L (prior to being built in) of 980 mm and a width of 600 mm.
  • the thickness of the illustrated implementation example amounts to 150 mm.
  • the dimensions of the board or the sheeting can be chosen to match the proposed application.
  • the board 1 is made available in such a way that its length L, here 980 mm, is slightly greater than the clear distance between the rafters.
  • the board 1 When the board 1 has to be built in, it is first compressed in the longitudinal direction and then pressed between the beams 6 of a ceiling 7 , the clear distance between the beams amounting to 960 mm. This means that the board is kept in position between the beams 6 by means of the pressure fit caused by the elastic restoring force built up during the insertion operation.
  • the excess length Ü is indicated in Figure 1 and in this particular case amounts to about 2% of the length L of the board 1.
  • Figure 2 shows the customary conveyer belt 8 transporting a strip or blanket 10 of mineral wool sheeting on its carrying run 9 ; the said mineral wool strip comes from the mineral wool production plant and the adjustable calibration roll 10' is used to bring it to the required thickness. As a general rule, the sheeting will then pass over the two conveyers 11 and 12 of a hardening kiln, where the binding agent is hardened to form the finished mineral wool sheeting strip.
  • At least two and preferably four additional conveyers 14-17 have to be provided before the hardening kiln 13 , the said conveyers being here shown as endless belt conveyers.
  • These conveyer belts are here arranged below the mineral wool strip or blanket 18 that is being taken to the hardening kiln 13 , so that the mineral wool strip 17 is being carried on these conveyers 14-17 until just before it enters the hardening kiln 13 .
  • These conveyers are arranged in immediate sequence and each downstream conveyer, say the conveyer 14 , is operated at a smaller speed than the immediately following upstream conveyer, here the conveyer 15 .
  • the method in accordance with Figure 2 can be used to produce an endless mineral wool strip with a desired crimping structure in the lower section, though it is equally possible to produce strips or boards of limited length. It will however be advantageous to produce an endless strip, in which case the required mineral wool boards can be obtained by appropriately sectioning the strip as it leaves the hardening kiln.
  • the mineral wool product in accordance with the invention makes it possible to provide heat insulation between rafters and beams without wasting material, since this product, given the partial crimping process to which it has been subjected, possesses an appropriate crinkling zone and can therefore compensate 1.5 - 5% of the clear distance between the rafters or beams without any problems.
  • the slight loss suffered by the so-called ⁇ -value as a result of the fibre realignment caused by the crimpling process is compensated by the fact that the initial gross density - which may lie in the range between 8 and 30 kg/m 3 , and particularly between 15 and 20 kg/m 3 - is stepped up by about 0.5 kg/m 3 as a result of the crimping process.
