Description
Verfahren zur Herstellung von Kunstholz aus Pflanzenfasern o. dgl. und Wasserglas Es wurde gefunden, dafi es bei dein Verfahren zur Herstellung von Kunstholz nach dem Patent 485 672 sehr vorteilhaft ist, bei Verwendung von Wasserglas als Bindemittel nicht nur Bariumsulfat bzw. Schwerspat als Zusatz zu verwenden, sondern überhaupt anorganische Calcium- und Bariumverbindungen in fester und pulverisierter oder gelöster Form der zu formenden Masse zuzusetzen.Process for the production of synthetic wood from plant fibers o. The like. And water glass It has been found that in the process for the production of synthetic wood according to patent 485 672 it is very advantageous not only to add barium sulfate or barium as a binder when using water glass as a binder use, but generally add inorganic calcium and barium compounds in solid and powdered or dissolved form to the mass to be molded.
Nach dem Hauptpatent" werden Strohoder Pflanzenstengel von Unkraut usw. entweder in Gegenwart von 'Feuchtigkeit ähnlich wie Leinenstroh geröstet oder im zerkleinerten Zustand mit Kalk gekocht, dann getrocknet und schließlich fein gemahlen. Die so vorbereiteten Fasern werden dann mit Wasserglas vermischt, unter Zusatz von z. B. Bariumcarbonat, Bariumchlorid, Bariumoxyd bzw. den entsprechenden Calciumverbindungen oder Leichtspat, Kalkspat, Flußspat usw., und zwar verwendet man z. B. die 5- bis 6fache Gewichtsmenge Wasserglas und z o bis 15 Gewichtsprozent der obengenannten Zusätze, beide Gewichtsmengen bezogen auf die trokkene Fasermasse. Durch Rühren und Kneten entsteht ein Teig, der, in Formen gepreßt, bei 5o bis 8o° langsam getrocknet wird, um Sprünge zu vermeiden. Es kann aber das Wasserglas auch in Pulverform zugesetzt werden.According to the main patent, "straw or plant stalks become weeds etc. either roasted in the presence of 'moisture similar to linen straw or Cooked in the crushed state with lime, then dried and finally fine ground. The fibers prepared in this way are then mixed with water glass, under Addition of z. B. barium carbonate, barium chloride, barium oxide or the corresponding Calcium compounds or light spar, calcite, fluorspar, etc., namely used one z. B. 5 to 6 times the weight of water glass and z o to 15 percent by weight of the above additives, both amounts by weight based on the dry fiber mass. Stirring and kneading creates a dough that, when pressed into molds, is kept at 5o to 8o ° dried slowly to avoid cracks. But the water glass can do it too be added in powder form.
Auf diese Weise entsteht ein Kunstholz mit ,ähnlichen, aber festeren Eigenschaften als nach dem Hauptpatent 485 672, das im trocknen Zustand gesägt, gefeilt, gehobelt, ,gebohrt und - mit geeigneten Poliermitteln poliert werden kann. Durch Verringerung der Zusätze kann das spezifische Gewicht des- Kunstholzes vermindert werden, durch Vermehrung werden dem Holz steinartige Eigenschaften verliehen. Außerdem ist das Endprodukt auch weitgehend feuerfest und kann mit geeigneten Anstrichen auch wasserfest gemacht werden.In this way, a synthetic wood is created with, similar but stronger properties than according to the main patent 485 672, which in the dry state can be sawn, filed, planed, drilled and - polished with suitable polishing agents. By reducing the additives, the specific gravity of the synthetic wood can be reduced; by increasing the number, the wood is given stone-like properties. In addition, the end product is also largely fireproof and can also be made waterproof with suitable paints.
