Definitions
- the invention relates to a method for producing a wood-based panel, the method comprising the following steps: a) scattering a plurality of wood particles into a particle cake, wherein at least one adhesive is applied to at least some of the wood particles before scattering and / or during scattering,
- the invention also relates to an apparatus for carrying out such a method.
- Wood-based panels are today used in a wide variety of applications, for example as a floor covering, as wall cladding, in furniture construction or in structural timber construction.
- Wood-based materials are made of wood particles and adhesive, which are usually pressed in a continuous process under heat and pressure to wood-based panels. This method is known as "hot pressing" and can be carried out continuously or clocked.
- Known representatives of wood-based panels are, for example, OSB (Oriented Strand Board according to EN 300), in which strands can be scattered in several alternately crossing layers, chipboard according to EN 312, in which wood chips can be spread in cover and middle layers or fiberboard according to EN 316, where the wood fibers are scattered to a mostly single-layered cake.
- WO 2005/046950 A1 proposes controlling the amount of scattered particles in a middle layer of the wood-based panel via control nozzles. It is known from EP 2 653 279 A1 to remove particles from a scattering curtain of the falling wood particles during scattering and in this way to achieve different bulk densities of the wood-based panel. The removed particles can then be fed to a further scattering process. From DE 10 2013 002 259 A1 it is known to measure the density of the scattered particle cake and then to remove the desired amount of particles in order to achieve the selected profile.
- the invention is therefore based on the object to provide a method with which physical and / or chemical properties of a wood material panel to be produced can be adapted spatially almost without restriction.
- the invention solves this problem by a method according to the preamble of claim 1, which is characterized in that during the scattering of the wood particles of different amounts of at least one additive at different positions are introduced within the particle cake.
- a method according to the preamble of claim 1 which is characterized in that during the scattering of the wood particles of different amounts of at least one additive at different positions are introduced within the particle cake.
- it is possible to change the local composition of the particle cake and, for example, not only to vary the amount of particles at different locations, but also, for example, the ratio of wood particles to the additive and / or the ratio of the adhesive to the additive individually adapt. This is with a subsequent removal of particles can not be reached from the particle cake.
- inhomogeneities and stratification which would occur if the wood particles and the additives were applied in layers one after another, are prevented.
- the at least one additive contains at least one adhesive, at least one fire-retardant substance, at least one biocidal substance, at least one substance for swelling of wood, at least one foaming agent and / or at least one substance which is an optical and / or haptic and / or the one physical and / or a chemical property of the wood-based panel, for example, their electrical conductivity and / or thermal conductivity changed.
- white pigments such as titanium dioxide or calcium carbonate be given, which cause a lighter plate.
- a decor is applied to the plate in direct printing.
- the plate is primed white, for which a brightest plate is advantageous. The brighter the starting material, in this case the wooden board, the sooner the white ground becomes effective.
- pigments or colors may be added which color the wood-based panel or at least one of its cover layers.
- stripes, geometric patterns or other colorations A can be achieved, which can also be multicolored.
- Dyes and pigments may be used in each case or together with other, optionally colorless additives, for example, to recognize a distribution and positioning of the additive.
- Other possible properties that can be changed or adjusted by the addition of at least one additive are, for example, a hydrophobing example by paraffins and a VOC reduction by the addition of appropriate scavengers.
- the list of properties and additives described here is not exhaustive, but rather an extract.
- the bulk density of the plate to be produced is reduced at certain points, which is particularly advantageous if mechanical stress is not or not to be expected to a large extent at the desired locations. In this way, the plate can be made easier and thus manageable for the end user.
- Different positions within the particle cake, at which different amounts of an additive are introduced during the scattering of the wood particles, may differ in all three spatial dimensions.
- different distributions can be used in the x and / or y direction and of course the use of different distributions in a z direction perpendicular thereto is also possible.
- Many properties are used, for example, only in the edge regions of a wood-based panel or only in the central region of the wood-based panel.
- an impregnation against penetrating moisture, in particular in the outer layers of advantage while, for example, a lower density and thus a lower weight, especially in the middle core layer is advantageous.
- the wood-based panel may also be useful to provide certain properties in some strips or areas of the wood-based panel, but then distributed over the entire thickness. This applies, for example, the thermal conductivity when using wood-based panels as constructive components. Also, the electrical conductivity or resistance to, for example, fungal infestation, which can be produced by biocidal substances, can be pronounced to different degrees in spatially different areas.
- different additives and / or different amounts of different additives are introduced at different positions within the particle cake. It is advantageous for many applications to use several different additives in a wood-based panel, in particular to influence different properties.
- each of the different additives may have a spatially inhomogeneous distribution, so that the cases mentioned can occur. While in some places only one or some of the additives used are present, are all additives are present in several different places, but the proportions of the different additives differ at these positions. There are hardly any limits to the quantity ratios.
- the amount of wood material particles that are scattered to the particle cake, depending on their expected position in the particle cake is varied.
- the amount of scattered wood particles and the type and / or amount of introduced additives is advantageously selected such that the wood-based panel has a homogeneous density.
- the invention solves this problem also by a device for performing a given method, which has a loading device and an electrical control, which is adapted to control the introduction device such that during the scattering of the wood particles differently large amount of at least one additive to different Positions are introduced within the particle cake.
- the electrical control has an electronic data processing device which is set up to access information stored in an electronic data memory and to control the introduction device on the basis of this information.
- the electronic data storage may be part of the device.
- the electrical control has an interface for communication with an external electronic data processing system, such as a laptop or a computer, wherein the electronic data storage is part of this electronic data processing system.
- the communication can be wired or wireless, for example via WLAN or Bluetooth.
- the introduction device has at least one scattering head with at least one scattering nozzle for scattering wood particles and at least one additive material nozzle for scattering at least one additive.
- the at least one scattering head has at least two different additive material nozzles for scattering different additives.
- Figure 1 the schematic representation of an apparatus for performing a
- Figure 2 the schematic representation of a wood-based panel.
- FIG. 1 shows an apparatus for producing a wood-based panel.
- wood 2 is provided, which is comminuted in a crusher 4 to wood chips. These are washed in a washing device 6 and then boiled in a pressure vessel before the fiber pulping takes place in a refiner 8.
- glue is added in a gluing device 10 so that glued wood particles are formed. These are dried in a drying device 12 and then subjected to quality control in a classifier.
- the glued wood particles are then fed to a loading device 16, which has several scattering heads 18 in the embodiment shown, three of which are shown. Only the left scattering head 18 is shown by solid lines. The others are dashed to show that they are optional.
- the various scattering heads 18 are used to spread and scatter different additives and thus introduce them into the scattered particle cake.
- An additional scattering head not shown, is provided to scatter the wood particles.
- By the differently long dashed lines 20 it is shown that from different scattering heads 18 different additives are scattered.
- the so-spilled particle cake enters a supercharger 22, before it is pressed in a hot press 24 to a wood-based panel.
- FIG. 2 shows a schematic sectional illustration through a wood-based panel 26.
- a first additive 28 which is shown in the form of small circles and which can be, for example, glass balls or expanded clay, which is located in a plane between a top side 32 and a bottom 34 is distributed almost homogeneously. In this way, for example, the bulk density of the wood-based panel 26 can be reduced in this area, and thus weight can be saved.
- a second additive 30, which is shown in the form of lines, is arranged rod-shaped in the wood-based panel 26. This may be, for example, an additive which increases or reduces the electrical conductivity and / or the thermal conductivity of the plate, whereby certain transport paths for heat and / or electrical charge are generated.
