- Wood fiber insulation materials are in direct competition with insulation boards made of mineral or glass fibers.
- a special insulation board made of mineral fibers as a plaster base with special tear-off strength, as a slat plate referred to as.
- a slat plate is made that first a starting plate made from mineral fibers whose thickness corresponds to the later width of the lamella plate. Strips are then sawn out of the starting plate, which correspond to the slat plates. That is, the breadth of the Stripes form the thickness of the lamella plates.
- the front one Surface as well as the rear surface with which the Slat plate begins and ends in the insulation direction sawn surfaces.
- the mineral fibers in the Slat plate a preferred orientation parallel to a cross from the front surface and across to the rear surface level at that of the original manufacture the starting plate comes from the mineral fibers.

The opposing heating surfaces are distance-controlled to maintain a predetermined distance from one another, and a bulk density profile of the wood fiber boards is set so that there is an edge increase in the bulk density compared to the average bulk density of the wood fiber boards of at least 20%.
- the fiber moisture of the fibers when calibrating the fiber mat and during the heat treatment for curing the binder can, as in the case of conventional so-called drying processes, be in the range of below 10%.
- the heat treatment of the fiber mat takes place via smoothly closed heating surfaces, via which the heat is transferred to the fiber mat to harden the binder. It is important that the heating surfaces are distance-controlled and not pressure-controlled, as is the case when conventional drying processes are carried out.
- the very low bulk density of the wood fiber boards produced by the present method does not allow controlled pressure control of the heating surfaces.
- a raw density profile is imprinted on the wood fiber boards produced, which has an edge increase in the raw density compared to the average bulk density of the wood fiber boards of at least 20%.
- the edge areas of the wood fiber boards are thus compressed in relation to their average bulk density.
- This smoothly closed surface is unusual for wood fiber boards in the density range below 250 kg / m 3 . It enables simple and precise flat bonding of individual wood fiber boards during the production of the new molded inserts.
- the fiber mat through the heating surfaces controlled at a distance can also be calibrated.
- the specified distance between the heating surfaces and the thickness of the manufactured ones Corresponding to wood fiber boards is typically 20 to 300 mm. It is just in the larger area Thicknesses in this area are astonishing that the fiberboard can still be produced using a dry process.
- the bulk density profile of the wood fiber boards like this is set that there is an edge increase in the bulk density compared to the average bulk density of the wood fiber boards from results in at least 60%.
- a stronger edge increase of the bulk density is the basis for the training of a particularly firm closed surface of the finished fiberboard, the for example, a considerable pressure stability compared with the average bulk density of the wood fiber boards can.
- a conventional synthetic resin of the wood-based panel industry can be used as a binder.
- the usual synthetic resins of the wood-based panel industry include urea-formaldehyde, melamine-urea-formaldehyde, melamine-urea-phenol-formaldehyde, phenol-urea-formaldehyde, phenol-formaldehyde and PMDI resins.
- the average bulk density of the wood fiber boards is set to 60 to 250 kg / m 3
- a foam-forming polyurethane binder can be used as the binder.
- the advantage of filling the cavities in the wood fiber board between the individual fibers by the polyurethane foam has a positive effect.
- the particularly light wood fiber boards in the range below 150 kg / m 3 cannot be produced in a usable quality without the use of a foam-forming binder.
- foam-forming polyurethane binder As a foam-forming polyurethane binder, a so-called One-component system are used, which for example was developed by Bayer and basically is available. Preferably, however, it is easier to control Two-component system used, the foam-forming Polyurethane binder a first, NCO group-containing Binder component and a second at least one polyol having binder component.
- the first batch mentioned can generally be 10 to 90% and the second lot corresponding to 90 to 10% of the total fibers contain. But it makes perfect sense if the first and the second lot of fibers are approximately the same size, d. H. for example each contain 40 to 60% of the total fibers.
- the process described here can be carried out batchwise as well as continuously, which is preferred.
- the heating surfaces are typically on rear heated metal endless belts intended.
- the lots of fibers can after the application of the binder components and before their mixing are stored separately from each other.
- the reactivity of the binder components decreases with separate intermediate storage the parts of the fibers do not fall off even over longer periods of time.
- the heat treatment for curing the wood fiber boards can be made so that in the middle of the molded body a temperature of only 50 to 100 ° C is reached.
- the fibers used in the manufacture of the wood fiber boards processed wood fibers in the form of usual defibrator fiber.
- the proportion of binder can be used in the manufacture of wood fiber boards be chosen within wide limits by the necessary strength of the wood fiber boards on the one hand and the economy of the process in view of high binder costs on the other hand are set.
- the following information refer to the use of a PUR binder.
- the binder content of the wood fiber boards to a total of 2.5 to 5% by weight based on atro Wood fibers set. This results in molded inserts, some of them as pure thermal insulation bodies and at higher bulk densities also as wall elements with high rigidity and high insulation potential can be used.
- the process described here for the production of wood fiber boards can also be carried out so that when molding the preform from the fibers a layer structure with different Compositions and / or proportions of the binder in the individual layers is set.
- the binder content in the top layers of the wood fiber boards be larger than in the middle class by one to achieve particularly high stability of the cover layers. It but are also other layer structures to adapt to certain requirement profiles with the new procedure realizable. It goes without saying that lots of fibers, provided for different layers of the layer structure are not together before forming the fiber mat are mixed, but only those fibers for each a layer with a uniform composition is provided.
- mechanically stable wood fiber boards are obtained using the process described here only using a foam-forming binder, ie a polyurethane binder which has at least two binder components, PMDI and polyol, or which is a one-component system , Such wood fiber boards can also be viewed as polyurethane foam stabilized by fibers.
- the binder content of atro fibers is at least 5%, which in absolute terms is not much.
- binder proportions From an average bulk density of about 150 kg / m 3 , fewer voids are present between the fibers, so that the proportion of binder can be reduced to below 5% atro fibers when using a foam-forming polyurethane binder. If the stabilities are not in the foreground, binder proportions down to above 1% can be sufficient. All percentages are understood as usual as percentages by weight.
- non-foam-forming binders ie conventional synthetic resins in the wood-based panel industry
- the proportion of binder should also be selected for lower strengths above 5%, and for higher strengths 7 to 15% of binder should be used.
- Mixing systems with the addition of melamine and phenols are preferred instead of the relatively fragile curing urea-formaldehyde resins. The usual trade-offs must be made between the price of the binder, possible formaldehyde elimination and possible harmful residual phenols.
