Definitions
- the invention relates to a method for the continuous production of a multilayer wood fiber board with an OSB core layer according to the preamble of patent claim 1.
- OSB core layer Oriented Strand Board
- OSB core layer Oriented Strand Board
- the middle layer consists of the same long chips, but offset by 90 ° transversely to the longitudinal scatter. This results in a high flexural strength coarse particle board, as it has been used successfully for years.
- OSB boards have been proposed many times. Difficulties for the industry are that the OSB boards are not easily coatable because, above all, the surface of this coarse chipboard does not result in a sufficiently smooth surface. This surface structure cannot be sufficiently improved for this even by subsequent grinding of the surfaces.
- OSB panels that were calibrated in thickness beforehand, if necessary, were subsequently coated with a veneer layer on both sides, for example.
- the three or possibly more layers are spread continuously by over scattering stations arranged one behind the other and the layers thus scattered to form a material to be pressed are subsequently pressed together once in one operation in a continuously operating high-pressure press.
- a subsequent grinding calibration is carried out only once with less grinding compared to the previously described method, where grinding is carried out at least four times.
- the cover layers are formed from fine chips, or MDF or HDF.
- the process is essentially characterized by the following process steps: - the lower cover layer is first sprinkled onto the forming tape from a Femspan chip mixture; - At least one layer of oriented long chips is sprinkled on the lower chipboard thus formed to form the OSB core layer; - The top cover layer is then sprinkled from a Femspan-chip mixture over the last core layer - The mat thus formed is then pressed in a press to form a multi-layer wood fiber board and cured.
- the lower cover layer can - as already mentioned - be pre-compacted before the OSB layers are sprinkled in, and the pressed material mat can be brought into the final shape using pressure and heat and cured.
- the multi-layer wood fiber board is to be manufactured in a continuous process.
- the effect of hot air in the spreading stations can preheat the chips / fibers to an elevated temperature in the range of 60 ° C to 80 ° C.
- the layers of the OSB core layer are preferably sprinkled from a starting mixture which is mixed with isocyanate or phenolic resin as a binder.
- the two cover layers are preferably sprinkled from a starting mixture which is mixed with urea / formaldehyde resin binder.
- the OSB core layer will also consist of three layers, e.g. it is scattered in three layers, the middle layer preferably being made up of long chips oriented transversely to the direction of movement of the scattering belt and the two outer layers being made up of longitudinal chips
- Wood-based panels produced by the method according to the invention can also be additionally coated.
- the at least one femspan cover layer can be coated with plastic.
- planing and / or sawing chips of the OSB core layer which form a reinforcing middle layer in one, two or more layers, not only from softwood, which is known at OSB, but also at least in part from other softwood, for example birch or Poplar wood, and / or hardwood, for example beech or ash and / or a mixture thereof.
- a preferred wood-based panel produced by the method according to the invention has an OSB core layer, in turn containing wood shavings with a proportion of at least 50% by weight, for example 60% by weight to 80% by weight. %. It also has a thickness of 0.5 cm to 5 cm.
