Abdeckmittel zur Förderung des Wachstums von Pflanzen Patentiert im Deutschen Reiche vom 29. August 1929 abCovering agent to promote the growth of plants. Patented in the German Empire on August 29, 1929
Abdeckmittel zur Förderung des Wachstums von Pflanzen unter Benutzung biegsamer, mit Imprägnierungs- bzw. Düngemitteln versehener Stoffe, die mit Durchtrittsöffnungen für die Zuführung von Wasser bestimmt versehen werden, sind bereits bekannt. Diese Abdeckmittel hatten jedoch den Nachteil, daß sie bei dem großen Bedarf, selbst in großen Mengen hergestellt, zu teuer wurden, um die erheblichen Nachteile der Feuchtigkeitsbeeinflussung auszuschließen, da bei einer vorzeitigen Zerstörung des Bodenbelages der eigentliche Zweck nicht erfüllt werden würde.Covering means for promoting the growth of plants using flexible, with impregnation or fertilizers provided with through openings intended for the supply of water are already known. However, these cover means had the Disadvantage that they are too expensive in view of the great demand, even produced in large quantities in order to exclude the considerable disadvantages of the influence of moisture, since in the event of premature destruction of the floor covering, the actual purpose is not fulfilled would be.
Gegenstand der Erfindung beseitigt diese Nachteile, ist billig in der Herstellung und gewährleistet trotzdem eine lange Wetterbeständigkeit bzw. Haltbarkeit.The object of the invention overcomes these disadvantages, is inexpensive to manufacture and nevertheless guarantees a long weather resistance or durability.
Die Erfindung beruht auf der Erkenntnis, daß sich die zähen Fasern der Natronkraftcellulose besonders gut für die Präparierung bzw. Imprägnierung des fertigen Natronkraftpapiers eignen, da die Struktur der Fasern trotz Heißbehandlung erhalten bleibt, wobei die Fasern gleichzeitig von ihrer Saugfähigkeit völlig befreit, keiner Feuchtigkeitsbeeinflussung und keinem Verlust ihrer Festigkeit mehr ausgesetzt sind.The invention is based on the knowledge that the tough fibers of the soda power cellulose especially good for the preparation or impregnation of the finished soda kraft paper suitable, as the structure of the fibers is retained despite the heat treatment, whereby the fibers at the same time benefit from their absorbency completely freed, no longer exposed to the influence of moisture and no loss of strength.
Zu diesem Zweck werden bei der Herstellung des aus ioo°/Qiger Natroncellulose bestehenden, an sich bekannten Rohpapierstoffes die Fasern desselben so lange einer Heißimprägnierung, z. B. mit einer bekannten, Düngemittel enthaltenden Asphaltlösung, ausgesetzt, bis sie von ihrer Saugfähigkeit, ohne Beeinträchtigung der Festigkeit und Zähigkeit des fertigen Abdeckmittels, völlig befreit sind.To this end, the strength of ioo ° / Q sodium cellulose existing, known per se Rohpapierstoffes the fibers are the same as long as a hot-impregnation, for at manufacture. B. with a known, fertilizer-containing asphalt solution, exposed until they are completely freed from their absorbency without impairing the strength and toughness of the finished covering agent.
