Definitions

  • the invention relates to a process for the preparation of products Mineral wool according to the preamble of claim 1 and according to this method single-layer and multi-layered products according to the preambles of the claims 19 and 21.

  • the perforated element arise endless nonwovens, in which with respect to basis weight, width, Fiber orientation and homogeneity corresponding properties of the following Pretend product. These properties can not be done later be changed substantially, so that generated during the deposition of the chute Orientations of the fibers in the fleece or inhomogeneities in the later product are given if the fleece is not subsequently split or doubled, or separated into adjacent tracks.
  • the basis weight is at constant fiber input by varying the speed the perforated separation element influenced, wherein the Fiber orientation usually runs substantially laminar. Under “laminar” is here to understand that the fibers are substantially parallel to a surface, usually their support surface, are oriented. In the production of the fleece must the total amount of air / gas passing through the forming web. It will depending on Basis weight and available suction surface different Negative pressures needed in the suction.
  • Inhomogeneities of the binder distribution may also occur, such as several times wetted wool accumulations, which are repeatedly due to backflow in the area of Binder spraying were arrived, or fiber bundles, the area of the Spraying happened too fast.
  • Such binder deficiencies or Enrichments are in the final product z. B. recognizable by color differences.
  • For the Achieving the full functionality of the bond must, because of the inhomogeneous Distribution of the binder to be added to a greater amount of binder than theoretically necessary.
  • the inhomogeneous wool distribution can also vary in locally different Area weights of the nonwoven, which consist of locations of different densities result. Influencing such fluctuations in wool distribution Quality features negative, such as in particular the thermal resistance, but also the mechanical strength. Especially at low densities where the Regions with further reduced density are visually recognizable, the achievable Minimum density increased by such inhomogeneities, even visible defects how to avoid "holes". The result must therefore be higher on average Density as actually needed to be driven to these inhomogeneities of wool distribution Take into account. This leads to higher production costs and thus higher Product costs and to reduce the thermal resistance due to the higher density. The result is a product which is a quality which deviates from the theoretically possible quality.

B. a raw density increase from originally 30 kg / m 3 to 50 kg / m 3 . It has further been found that the size of the mineral wool flakes produced is of importance in order to obtain an isotropic structure in the final web, and it has been determined from many tests that the mineral wool flakes preferably have an average radial extent of 10 to 30 mm, in particular 15 +/-. 5 mm should have.

Transverse to the production direction according to arrow However, lying fibers of the laminar product did not become aligned affected. In that regard, the product 20 is over its frontal width at the end face 23 still laminar after compression.
  • the product 20 must be designed for certain surface tension or surface pressure loads to which it is exposed during use. To achieve these strengths, a certain bulk density must be maintained as the product becomes stronger with higher bulk density. For example, to obtain a surface tensile strength of 30 kN / m 2 , the product 20 may require a bulk density of 130 kg / m 3 . In order to achieve a surface compressive strength of 60 kN / m 2 , a bulk density of 160 kg / m 3 may be required. Increased bulk density leads to increased use of material and thus increased costs and above a bulk density of about 50 to 70 kg / m 3 to a reduction of the thermal resistance by increasing the thermal bridges to the fibers, so a drop in quality.

  • An essential further field of application of the present invention is in Composite products, wherein the use of the invention at least always take place there can, where conventionally with compression processes (Crepage) one worked.
  • Such a composite product is shown as product 50 in FIG.

Both the binder distribution as well as the wool distribution are considerably more uniform. Thus, the anchor tensile strengths vary at different points of a facade insulation board only insignificant, so that no Dübel malzugsfesttechnik "must be kept” to Compensate for weak points.
