Abstract
Natürliche Bastfasern aus Hanf, Flachs, Kenaf oder Nessel sollen zu Ton- und/oder Zement und/oder Kalkmischungen in einer Feinheit und Menge beigemischt werden, die ausreicht, um gleichwerte oder bessere Haltbarkeiten, Biegezug-, Druck- und Zugfestigkeiten als ebensolche Mischungen, mit oder ohne Beimischung künstlich hergestellter Fasern, zu erreichen. Die Vorteile liegen in der ökologischen Herstellung der Rohstoffe (Nachwachsende Rohstoffe) und im Preisunterschied: Naturfasern kosten ca. 10 - 15 ÖS per kg, Kunstfasern kosten ca. 110 - 150 ÖS per kg. Der österreichische Jahresbedarf liegt zur Zeit bei 10.000 t Kunstfasern. Natürlich gewachsene Schäben aus Hanf sollen zu Homogen- oder MDF Platten in einer Feinheit und Menge beigemischt werden, die ausreicht, um gleichwertige oder bessere Eigenschaften als solche, die aus Holz bestehen, oder Flachsschäben beigemischt wurden, zu erreichen. Die Vorteile liegen in der ökologischen Herstellung der Rohstoffe (Nachwachsende Rohstoffe) und im Preisunterschied: durch ein wesentlich niedrigeres Schüttgewicht als Holz wird mehr Volumen pro kg Hanfschäben erreicht. Dadurch verringert sich der Rohstoffpreis pro m3 Volumen gegenüber nach herkömmlichen Methoden hergestellten Homogen- oder MDF Platten.Natural bast fibers made from hemp, flax, kenaf or nettle should be mixed with clay and / or cement and / or lime mixtures in a fineness and quantity that is sufficient to achieve equivalent or better durability, flexural strength, compressive strength and tensile strength than the same mixtures, with or without the addition of artificially produced fibers. The advantages lie in the ecological production of the raw materials (renewable raw materials) and in the price difference: natural fibers cost approx. 10 - 15 ÖS per kg, synthetic fibers cost approx. 110 - 150 ÖS per kg. The Austrian annual requirement is currently 10,000 t of synthetic fibers. Naturally grown hemp shives should be mixed into homogeneous or MDF boards in a fineness and quantity sufficient to achieve equivalent or better properties than those made from wood or flax shives. The advantages lie in the ecological production of the raw materials (renewable raw materials) and in the price difference: due to a significantly lower bulk density than wood, more volume per kg of hemp shives is achieved. This reduces the raw material price per m3 volume compared to homogeneous or MDF boards manufactured using conventional methods.
