  • An OSB board in the sense of this invention consists of at least one layer which is constructed with flat wood chips, so-called strands.
  • the above-described layer forms the lower and upper cover layer and between them is the middle layer (in a 3-layer design), which has no preferred orientation of the stands. This distribution is also called "random" in technical language.
  • the middle layer is the innermost layer of the plate.
  • a 3-layered plate thus consists of an upper and a lower cover layer and a middle layer, a 5 or more layered plate of an upper and lower cover layer, a central layer and layers between the upper and lower cover layer and the Central location.
  • a preferred embodiment of the invention is a 3-layer plate, 5-layer or multi-layer plates (an odd number of layers being useful). Even numbers of layers are just as conceivable.

  • the present invention describes a large-sized wood-based panel, a component produced therefrom and a method for producing a large-sized plate with high mechanical properties such as the characteristics of bending, tension and pressure, without raising the specific gravity of the plate above the usual level. Furthermore, technological features of an OSB board are described, from which one can derive these increased mechanical properties and possible uses of this OSB board.
  • Influencing parameters for the preferred embodiments of the present invention are the beach geometry (length, width, thickness), the alignment of the beach plies, the orientation of the strands within a ply in a desired direction, the proportion and type of binder or the mixture of several binders, the proportion of additives such.
  • the ratio between the thickness between the outermost layer and the middle layers or the middle layer, the density profile, which is influenced by the targeted control of process parameters and ultimately the total thickness of the plate and the plate format, which on the intended use are coordinated.

  • the properties of the wood-based panels according to the invention are influenced by the beach geometry and the most uniform design of the strands of the cover layer, the ratio of thickness of the cover layers to total thickness or the basis weight of the cover layer to the total basis weight of the plate and the average specific gravity of the plate (density).
  • the two outer layers should consist in the finished product of at least 30 percent by weight of the total scattered chip quantity, which in sum of upper and lower cover layer corresponds to a proportion of at least 60%.
  • the remaining 40% account for the middle layer in a 3-layer plate.
  • the specific weight of the plate should not exceed 700 kg / m 3 , a value equal to or less than 650 kg / m 3 is desirable. This information refers to dry plates.
  • the production of the strands is usually made of round wood, which is preferably present in debarked condition.
  • the log logs are fed to a flaker, which produces strands of the desired dimension in a single operation by means of rotating tools.
  • a multi-stage production of the beaches is just as conceivable as z. B. from a rotary veneer, which is crushed into strands in a further step.
  • Fines are strands that are significantly different from the dimensions of the strands described above. Primarily during the production of fines should be avoided such as. B. by a gentle debarking and by regular sharpening of the cutting tools of the flaker. After Strandher ein a separation of the fine material from the beach but also conceivable.

  • the proportion of fines can be quite 10 to 15 weight percent based on the weight of the finished plate.
  • the wood of the beach is not relevant. In principle, all types of wood such. As poplar, birch, beech, oak, spruce, pine and the like possible.
  • the jaw has been particularly suitable due to its good Chipping properties and exposed due to their relatively high resin content.
  • paraffins and / or waxes are added.
  • the application can take place in the form of a melt at the required elevated temperature (liquid wax application) or for emulsions at about room temperature.

  • melamine-urea-formaldehyde glues (MUF) or melamine-urea-phenol-formaldehyde glues (MUPF) by co-cooking in the same reaction vessel (reactor) are produced.
  • the individual layers of the plate may also contain different types of binders and mixtures thereof, wherein it is advantageous for multi-layer plates for stability reasons, those layers, which are each arranged - in relation to the plate surfaces - in the same position, with the same binder type or to provide the same mixture.

  • the drums have built-in components, in order to be able to constantly pick up the beach material and to transport the beach material from the inlet into the drum to the outlet.
  • An oblique inclination of the drum in the longitudinal direction can assist the forward movement of the strands.
  • the achievement of the desired mechanical and technological properties is influenced by the targeted orientation of the strands.
  • The% set of chips, which may deviate more than +/- 15 ° from the selected direction of orientation is small. Nevertheless, in the "transverse" direction of the plate, there are still sufficient strengths and stiffnesses, since the scattering process always gives a deviation from the desired orientation.
  • the target orientation of the strands will depend on the position of the beach ply within the panel.
  • the two outermost layers, the cover layers, should be aligned parallel to the plate length as previously described for a single-layer plate.
  • the strands of the single center layer are oriented without a preferred direction (random).
  • a plate structure of more than 3 layers is also conceivable.
  • the number of layers will be odd

  • the preferred beach orientation of these other layers is crosswise to the beach orientation of each outer adjacent location.
  • a random orientation of individual layers is also possible.
  • the shaping of the beach mat from the various superimposed layers is accomplished by a spreader. For each layer is usually a scattering head available. This The task is to arrange the glued strands in the desired direction or randomly orient them. After spreading the mat, the pressing takes place to a stable plate-shaped product under the action of pressure and temperature. This can be done either in cycle presses (single or multi-day presses) or in continuous presses. The latter make it possible to produce an endless plate belt which can be cut into the desired formats.
  • the plates can be ground after production. This achieves a homogeneous plate thickness with small thickness tolerances and improved conditions for gluing two or more plates to components as described below. However, with sufficient board surface quality and sufficient thickness tolerance of the boards, gluing without prior sanding is also possible.
