HolzspanWood chip
Die Erfindung betrifft einen Holzspan.The invention relates to a wood chip.
Die erfindungsgemäßen Holzspäne stellen ein baubiologisch einwandfreies, thermisches Isoliermaterial dar, das in Hohlräume von Gebäudeteilen, z.B. Fehlböden, eingefüllt werden kann. The wood chips according to the invention represent a biologically sound thermal insulating material that can be filled into cavities in building parts, e.g. false floors.
Bekannte Isoliermaterialien für diese Zwecke sind Glas- und Mineralwolle. Der bei diesem Material auftretende Feinstaub aus kleinen und kleinsten Faserbruchstücken kann bei empfindlichen Menschen zu Reizungen der Haut und Atemwege führen. Daher liegt der Erfindung die Aufgabe zugrunde, ein Isoliermaterial zu schaffen, das die Anforderungen in baubiologischer Hinsicht erfüllt und schwerentflammbar ist. Diese Aufgabe wird erfindungsgemäß durch den Holzspan gemäß Schutzanspruch gelöst.Known insulating materials for these purposes are glass and mineral wool. The fine dust from small and tiny fiber fragments that occurs in this material can cause irritation to the skin and respiratory tract in sensitive people. The invention is therefore based on the object of creating an insulating material that meets the requirements in terms of building biology and is flame-retardant. This object is achieved according to the invention by the wood chip according to the protection claim.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch im Querschnitt dargestellt.In the drawing, an embodiment of the invention is shown schematically in cross section.
Der erfindungsgemäße Holzspan besteht aus einem Kern (1) aus einem üblichen Holzspan mit 0,1 bis 2 mm Dicke, 1 bis 30 mm Breite und 1 bis 20 cm Länge, wie er bei der Bearbeitung von Holz mit zerspanenden Werkzeugen anfällt, beispielsweise Hobelspäne od. Holzwolle. Dieser Holzspan ist allseitig mit einer 0,1 bis lmm dicken Schicht (2) aus Kalk, der gegebenenfalls bis zu 10 Gewichtsprozent Wasserglas enthalten kann, beschichtet. Die Beschichtung kann durch Mischen von nassen Holzspänen mit gebranntem Kalk oder durch Mischen von trockenen Spänen mit gelöschtem Kalk aufgebracht werden.The wood chip according to the invention consists of a core (1) made of a conventional wood chip with a thickness of 0.1 to 2 mm, a width of 1 to 30 mm and a length of 1 to 20 cm, as is produced when processing wood with cutting tools, for example wood shavings or wood wool. This wood chip is coated on all sides with a 0.1 to 1 mm thick layer (2) of lime, which can optionally contain up to 10 percent by weight of water glass. The coating can be applied by mixing wet wood chips with burnt lime or by mixing dry chips with slaked lime.
Anschließend werden die beschichteten Späne getrocknet, wobei die zunächst gebildete Calciumhydrocidschicht durch Aufnahme von Kohlendioxid aus der Luft in eine Calciumcarbonatschicht (Kalk) übergeht.The coated chips are then dried, whereby the calcium hydrochloride layer initially formed changes into a calcium carbonate layer (lime) by absorbing carbon dioxide from the air.
Die Kalkschicht (2) haftet fest auf dem Holzkern (1) und blättert auch beim Biegen des Spans nicht ab.The lime layer (2) adheres firmly to the wood core (1) and does not flake off even when the chip is bent.
Die erfindungsgemäßen Holzspäne lassen sich als kostengünstiger, isolierender Füllstoff in Hohlräume von Gebäudeteilen, wie Decken mit Fehlboden oder als Estrichunterlage verwenden. Sie sind durch die Kalkschicht schwerentflammbar und brennen praktisch nicht. Gegenüber dem bekannten Isoliermaterial aus Glas- oder Mineralfasern haben sie den Vorteil, daß sie aus natürliohen Materialien bestehen und keinen reizenden Feinstaub abgeben. Die erfindungsgemäßen Holzspäne wirken ausgleichend auf das Raumklima, da sie Feuchtigkeit aufnehmen und abgeben können.The wood chips according to the invention can be used as a cost-effective, insulating filler in cavities in building parts, such as ceilings with false floors or as a screed base. The lime layer makes them flame-retardant and they practically do not burn. Compared to the known insulating material made of glass or mineral fibers, they have the advantage that they are made of natural materials and do not give off irritating fine dust. The wood chips according to the invention have a balancing effect on the room climate because they can absorb and release moisture.
