Definitions
- An OSB board in the sense of this invention consists of at least one layer of flat wood shavings, so-called beaches is constructed.
- 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 middle layer.
- 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 invention is based on the technical problem of providing an OSB board which is suitable for large-scale use and, for example, can also be used for the construction of buildings.
- the present invention describes a large format Wood-based panel, a component made from it and a method for producing a large format Plate with high mechanical properties like for example, the parameters for bending, tension and pressure, because of that the specific weight of the plate over that to raise usual measure. Furthermore, technological Characteristics of an OSB board described from which one can derive these increased mechanical properties and possible uses of this OSB board.
- Influencing parameters for the preferred embodiments of present invention the beach geometry (length, Width, thickness), the orientation of the beach locations to each other, the orientation of the strands within a Location in a desired direction, proportion and style of the binder or of the mixture of several Binders, the proportion of additives such.
- Wood panels are determined by the geometry of the beach and the most uniform possible design of the beach Cover layer, the ratio of thickness of the cover layers to Total thickness or the basis weight of the cover layer for total basis weight of the plate and the middle one specific weight of the plate (density) influenced.
- 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 beaches is usually done Roundwood, which preferably in debarked condition is present.
- the logs will become one Zerspanungsmaschine (Flaker) fed, which in one single operation by beach rotating tools the desired dimension.
- Zerspanungsmaschine Finlaker
- manufacturing the beaches is just as conceivable as z. B. from a peeled veneer, which in another Work step is shredded into strands.
- Fines content can be quite 10 to 15 percent by weight 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. When The pine is particularly suitable due to its good machining properties and due to their exposed relatively high proportion of resin.
- Paraffins or waxes are added.
- the application can in the form of a melt at the required elevated temperature (liquid wax order) or for emulsions at about room temperature.
- binder types have urea-formaldehyde glues (UF), melamine-formaldehyde glues (MF), phenol-formaldehyde glues (PF), binder based on Isocyanate (eg PMDI) but also binders based on proven by acrylates.
- UF urea-formaldehyde glue
- MF melamine-formaldehyde glues
- PF phenol-formaldehyde glues
- binder based on Isocyanate eg PMDI
- the mixture is not just a mixture of different types of ready-to-use binders understood, but also a mixture of different of the mentioned types, which already in the course of the Production as a mixture yields. So z. B.
- melamine-urea-formaldehyde glues (MUF) or melamine-urea-phenol-formaldehyde glues (MUPF) by cooking together be prepared in the same reaction vessel (reactor).
- the individual layers of the plate can also be different Include types of binders and mixtures thereof, where it is in multilayer plates Stability reasons is advantageous, those layers that each - based on the plate surfaces - in the same position are arranged with the same Binder type or the same mixture to provide. So has been shown to be the requirements of the invention be achieved very well in a 3-layer plate can, if the upper and lower cover layer with a MUPF binder is provided and the middle layer with an isocyanate-based binder (PMDI).
- PMDI isocyanate-based binder
- binder and the type of binder are decisive for the desired mechanical-technological Properties.
- the content of binder depends on the binder type. binder contents for UF, MF, PF and their mixtures are in the range between 10 and 15% by weight (for mixtures as the sum of used components) calculated as solid resin on the dry mass of wood strands. When using Isocyanates, the binder content to 5 to 10 wt. % be reduced.
- the gluing of the beaches takes place before the formation of the Beach mat. Usually, this is great dimensioned Beleimtrommeln provided that a allow continuous gluing in the pass.
- the Drums rotate around their own longitudinal axis and hold thereby the introduced beach material constantly in Move. In the drums, a finer one becomes by means of nozzles Leim mist generated that spreads evenly on the beach reflected.
- the drums have built-ins to on the one hand the beach material constantly pick up again and on the other the beach material from the enema in To transport the drum to the outlet. A Slanting the drum in the longitudinal direction, the Support forward movement of the beaches.
- Achieving the desired mechanical-technological Characteristics is determined by the orientation of the Strands influenced.
- The% rate of chips more than +/- 15 ° of may deviate from the chosen direction of orientation low. Nevertheless, in "transverse" direction of the plate, still sufficient strength and stiffness before, because through the scattering process always a deviation from the Target orientation is given.
- a plate assembly of more than 3 layers is as well conceivable.
- the number of layers becomes odd be, with the beach orientation of the cover layers and the Middle position as previously described and orientation the other layers can be arbitrary. So it is conceivable that the preferred beach orientation of these others Lay crosswise to the beach orientation of each outer adjacent location. A random orientation individual layers is also possible.
- the shaping of the beach mat from the different ones superimposed layers is from a spreader accomplished. For each layer is usually one Scattered head available. This has the task the glue Strands oriented in the desired direction or randomorientiert to arrange. After spreading the mat takes place pressing into a stable plate-shaped product under the influence of pressure and temperature. This can both in cycle presses (single or multi-day presses) done or in continuously operating presses. The latter enable the production of an endless Plate tape, which is separated into the desired formats can be.
- the plates can be ground after production. This achieves a homogeneous plate thickness with small thickness tolerances and improved conditions for the gluing of two or more panels to components as described below. If sufficient Plate surface quality and sufficient Thickness tolerance of the plates is but a gluing without previous touch also possible.
- FIG. 1 shows one as described above Wood-based panel 1, which consists of three beach locations is.
- the upper beach 2 shows a preferred Orientation of the strands 5 in the longitudinal direction of Plate. It can be seen that the beaches 5 of the Cover layer 2 not strictly parallel to the plate length are aligned, but still a high Orientation is given.
- the middle layer 3 exists from strands 6, which are slightly smaller in size are as the strands of the cover layers 2 and 4. The Alignment of the strands 6 of the middle layer 3 is random oriented.
- the lower cover layer 4 is a mirror image of upper cover layer 2 constructed.
- FIG. 1 also shows that the thickness s1 the two cover layers (both the lower cover layer 4 as also the mirror-image constructed upper cover layer 2) each about 30% of the total thickness s of the plate is and the Thickness s2 of the middle layer 3 about 40%.
- Single plates 1 can have a thickness s to about 50 mm and Formats of 2.8 x 15 m and may have in the construction sector be used manifold.
- the plate length of 15 m should not be understood as an upper limit here. It has been shown that both for the production and the subsequent disk manipulation in the course of Further processing here a meaningful order of magnitude 10 to 15 m.
- FIG. 2 shows a schematic view Such component 10 made of 3 individual plates 1 is.
- the individual plates 1 with an adhesive such as B. isocyanate at least partially over a large area bonded.
- This component can, for. B. in building forêtund Interior walls are used, with the benefits of that Elements according to the wall length seamless over one full storey height (up to 2.8 m) can be produced can.
- the common house building practice eg single-family home, Apartment building shows that wall elements with a Length between 10 and 15 m quite sufficient to whole To make wall, ceiling, and roof elements.
- carriers can be made such that Strip the desired beam width or beam height be made from it. The stripes will be cut out according to the length of the plate, bringing a Beam length up to 15 m is possible.
- These carriers can one or both sides with large format OSB boards be united for the training of ceiling, wall or Roof elements that have sufficient stability, Overvolt surges of several meters.
- FIG. 3 shows two different embodiments.
- Figure 3 a) consists of the ceiling, wall or roof element 20th from a carrier 22, an upper plate 21 and a lower plate 23.
- the plate 21 is in itself again from 2 individual plates 1, the carrier 22 is in itself again from 3 single plates 1.
- the plates 21 and 22 are with the carrier 22 positively or positively connected. Is the component 21 a Ceiling element, so the plate 21 takes over the function the floor of the upper floor and the plate 23 the Function of the ceiling of the lower floor.
- the carrier 32 is in Contrary to the carrier 22 arranged horizontally.
- FIG. 4 shows the structure of a large area Component 20 that from a variety of individual plates 1 is constructed.
- the length L can be up to 15 m and the Width B can be up to 2.8 m.
- the carriers 23, 33 are firmly connected to the plates 21,31 and 22,32. Thereby has the component in combination with the high mechanical-technological properties of the individual plates 1 itself over a high inertia.
