Description
Verfahren und Vorrichtung zur Herstellung von Isolationsmaterial aus
Stroh
Es hat sich in überraschender Weise gezeigt, daß bei einer solchen Behandlung des Strohes, die eine Mahl- bzw. Preßwirkung vermeidet, die Verbindung der äußeren glatten mit der inneren rauhen Schicht des Strohes nicht zerstört, wogegen bei den bekannten Verfahren, insbesondere beim Feinvermahlen, beide Schichten voneinander gelöst werden.It has been shown in a surprising manner that in such a Treatment of the straw, which avoids a grinding or pressing action, the connection the outer smooth with the inner rough layer of the straw is not destroyed, whereas in the known processes, in particular in fine grinding, both layers from one another be solved.
Das Haftvermögen der durch die erfindungsgemäße Arbeitsweise bloßgelegten inneren rauhen Schicht zum Bindemittel hat zur Folge, daß bei der Herstellung von Platten ein äußerst gutes Festhaften der verschiedenen Partikelchen gegeneinander erzielt wird, ohne daß die negativen Eigenschaften der glatten Außenfläche störend zur Wirkung kommen. Auch wird die Brennbarkeit des Produktes derart herabgesetzt, daß es praktisch als unverbrennbar bezeichnet werden kann.The adhesiveness of the exposed by the operation of the invention inner rough layer to the binder has the consequence that in the production of Plates ensure that the various particles adhere extremely well to one another is achieved without disturbing the negative properties of the smooth outer surface come into effect. The flammability of the product is also reduced to such an extent that that it can practically be called incombustible.
Dadurch, daß die Hohlräume des Strohes zerstört werden, wird auch das Eindringen von Feuchtigkeit verhindert. Aus diesem Grunde verbleiben die aus dem erfindungsgemäß behandelten Stroh hergestellten Bau- oder Isolationselemente dem Wasser gegenüber fast unempfindlich. Sie sind fast wasserabstoßend oder können leicht in eine solche Form übergeführt werden.By destroying the hollow spaces in the straw, too prevents the ingress of moisture. For this reason, they remain out the construction or insulation elements made of the straw treated according to the invention Almost insensitive to water. They are almost water-repellent or can can easily be converted into such a form.
Das erhaltene Produkt kann für verschiedene Verwendungszwecke in verschiedene Feinheitsgrade sortiert werden. Ferner können an und für sich bekannte Schutzmittel zum Imprägnieren verwendet werden, jedoch hat dieses sich z. B. gegenüber Brandgefahr in vielen Fällen als nicht nötig erwiesen.The product obtained can be used in different for different uses Degrees of fineness can be sorted. Furthermore, protective agents known per se can be used be used for impregnation, but this has z. B. against fire hazard proved unnecessary in many cases.
Das gemäß der Erfindung gespaltene Produkt eignet sich auch gut als Füllungsmittel in Gebäuden, weil es sich in überraschender Weise gezeigt hat, daß es, vor allem in einer richtigen Feinverteilung, von Wagetieren gemieden wird.The product cleaved according to the invention also works well as Filling means in buildings, because it has surprisingly been shown that it is avoided by daredevils, especially in a correct fine distribution.
Zur Herstellung von Isolationsplatten aus dem Strohprodukt gemäß der Erfindung sind die meisten an und für sich bekannten Bindemittel geeignet, z. B. auch die Kunstharze. Es hat sich gezeigt, daß der bei der Herstellung erforderliche Preßdruck in bedeutendem Maße vermindert werden kann.For the production of insulation panels from the straw product according to In accordance with the invention, most of the binders known per se are suitable, e.g. B. also the synthetic resins. It has been shown that the required in manufacture Compression pressure can be reduced to a significant extent.
Eine weitere Verbesserung des Strohrohstoffes wird erzielt, falls vor der Behandlung die leere Ähre entfernt wird. Jedoch hat es sich gezeigt. daß der Inhalt der Ähre meistens durch kräftige Blasen entfernt werden kann, wobei gleichzeitig die zu fein zerteilten Partikelchen ausgeschieden werden. Die Ähre kann auch leicht durch ein vor der eigentlichen Behandlung vorgenommenes mildes Zerschlagen entfernt werden.A further improvement in the straw raw material will be achieved if the empty ear is removed prior to treatment. However, it has been shown. that the contents of the ear can mostly be removed by vigorous bubbles, whereby at the same time the too finely divided particles are excreted. The ear of wheat can also be light removed by a gentle beating before the actual treatment will.
Für verschiedene Verwendungszwecke können die beim Sortieren erhaltenen Produkte verschiedenen Feinzerteilungsgrades miteinander in gewünschten Verhältnissen zusammengemischt werden. Dadurch ist die Möglichkeit gegeben, das Isolationsvermögen und die anderen Eigenschaften dieser Mischung im Verhältnis zu Volumen und Gewicht im voraus festzustellen.The Products of various degrees of fine division with one another in the desired proportions be mixed together. This gives the opportunity to improve the insulation capacity and the other properties of this mixture in relation to volume and weight to be determined in advance.
Es versteht sich, daß dasLängsweise-Aufspalten statt mit der erwähnten zerschlagenen »Stabmühle«, die vorteilhaft mit wenigstens teilweise elastischen Stäben versehen ist, auch mit Hilfe einer gezackten Fläche, z. B. einer Walze, erzielt werden kann, die gegen eine feste oder bewegliche Gegenfläche. ;>eventuell eine zweite Walze«, rotiert.It will be understood that splitting longitudinally instead of with that mentioned smashed "rod mill", which are advantageous with at least partially elastic Rods is provided, also with the help of a serrated surface, e.g. B. a roller achieved can be that against a fixed or movable counter surface. ;> possibly one second roller «, rotates.
Die Bewegungsrichtung der genannten Flächen kann entweder gleich, verschieden oder sogar entgegengesetzt sein. In dem letztgenannten Fall muß sich natürlich zwecks Förderung des Gutes die eine Fläche schneller bewegen als die zweite.The direction of movement of the surfaces mentioned can either be the same, be different or even opposite. In the latter case it must of course, for the purpose of promoting the goods, moving one surface faster than the second.
