296660 KLASSE 38/1. GRUPPE296660 CLASS 38/1. GROUP
Die Erfindung betrifft ein Verfahren zur Erhöhung der Zähigkeit des Akazien- und Zerreichenholzes derart, daß das Springen, selbst des ohne vorhergehendes Trocknen verarbeiteten Holzes verhindert wird. Infolgedessen können diese minderwertigen Holzarten auch als Werkzeugholz, insbesondere zur Herstellung von Werkzeugstielen sowie zur Erzeugung von Speichen mit Vorteil verarbeitetThe invention relates to a method for increasing the toughness of acacia and Oak in such a way that cracking, even that processed without prior drying Wood is prevented. As a result, these inferior types of wood can also be used as tool wood, especially for manufacturing of tool handles as well as for the production of spokes processed with advantage
ίο werden, wozu diese Holzarten bisher wegen ihrer Neigung zur Sprung- und Spanbildung nicht geeignet waren.ίο be what these types of wood are for so far their tendency to crack and chip formation were not suitable.
Die Werkzeugstiele, insbesondere die Hauenstiele, die aus dem nach dem beanspruchten Verfahren behandelten Holz hergestellt sind, besitzen noch die weitere vorteilhafte Eigenschaft, daß sich das Holz bei der Arbeit in Bergschächten in der Hand nicht erhitzt, und es kann demnach das wegen dieser Eigenschaft bisher mit Vorliebe verwendete Hickoryholz ersetzen.The tool handles, especially the pick handles, which emerged from the after the claimed Process treated wood are produced, have the further advantageous property, that the wood does not heat up in the hand when working in mountain shafts, and it can therefore be hickory wood, which has so far been used with preference because of this property substitute.
Das Wesen der Erfindung besteht darin, daß das Holz in einem etwa bis zur Siedetemperatur
des Wassers erhitzten, mit kohlensaurem Alkali, Alaun und einem schwefelsauren
Schwermetallsalz versetzten Wasserbad, bei atmosphärischem Druck, während einer längeren Zeitdauer behandelt wird.
In diesem Bade kann das frisch gefällte oder noch nasse Holz ohne vorheriges Trocknen
behandelt und das gekochte Holz nach Entnahme aus dem Bade und erfolgtem Auskühlen
sofort verarbeitet werden, ohne daß nachträgliche Sprungbildungen zu befürchten wären.The essence of the invention is that the wood is treated in a water bath heated to about the boiling temperature of the water, mixed with carbonate of alkali, alum and a sulfuric acid heavy metal salt, at atmospheric pressure, for a longer period of time.
In this bath, the freshly felled or still wet wood can be treated without prior drying and the cooked wood can be processed immediately after it has been removed from the bath and cooled down without fear of subsequent cracks.
Ein besonders bewährtes Ausführungsbeispiel ist das folgende: A particularly proven embodiment is the following:
100 1 Wasser werden bis zur Siedetemperatur erhitzt und mit100 l of water are heated to boiling temperature and with
1,5 kg Holzasche, 0,5 kg Alaun und1.5 kg of wood ash, 0.5 kg of alum and
0,5 kg schwefelsaurem Kupfer versetzt.0.5 kg of sulfuric acid copper was added.
In dieses bis auf etwa 100 ° C erhitzte Bad wird das Holz eingelegt und in einem offenen oder mit einem durchlöcherten Deckel bedeckten Gefäß während etwa 5 Stunden behandelt. The wood is placed in this bath, which is heated to around 100 ° C, and placed in an open one or a vessel covered with a perforated lid for about 5 hours.
Es ist bereits vorgeschlagen worden, eine innige Durchtränkung des Holzes zur Erzielung einer schweren Entzündlichkeit dadurch anzustreben, daß das Holz zunächst mit Eisenvitriollösung vollständig getränkt und hiernach mit Chlorkalzium und Kalkmilch behandelt worden ist.It has already been proposed to achieve an intimate impregnation of the wood A severe inflammability should be aimed at that the wood first with vitriol solution completely soaked and then treated with calcium chloride and milk of lime.
Um eine zweifache Behandlung zu vermeiden, wurde dieses Verfahren in der Weise abgeändert, daß das Tränken bei einer Temperatur von 135 bis 140 ° C und bei einem Druck von 2V2bis 3 Atmosphären vorgenommen wurde.In order to avoid double treatment, this procedure was modified in such a way that the soaking was carried out at a temperature of 135 to 140 ° C. and at a pressure of 2V 2 to 3 atmospheres.
Das vorliegende Verfahren unterscheidet sich gegenüber diesen bekannten Verfahren darin, daß die einmalige Behandlung im Bade nur unter atmosphärischem Drucke, also nicht über der Siedetemperatur des Wassers erfolgt.The present method differs from these known methods in that that the single treatment in the bath only under atmospheric pressure, so not over the boiling temperature of the water takes place.
Bei anderen als den eingangs erwähnten Holzarten würde diese Behandlungsweise, daIn the case of other types of wood than those mentioned at the beginning, this type of treatment would, since
eine vollständige Durchtränkung des Holzes angestrebt werden müßte; keine wesentliche Wirkung zur Folge haben, also zwecklos sein, während gerade das Akazien- und Zerreichenholz, also diese beiden geringwertigen und sonst kaum verwerteten Holzarten, durch die angegebene, einfache und mit geringfügigen Kosten ausführbare Behandlung den anderen Hartholzarten ebenbürtig werden, ohne daßa complete impregnation of the wood would have to be sought; no essential Have an effect, i.e. be useless, while the acacia and oak wood, So these two low-quality and otherwise hardly used types of wood through which the specified, simple treatment that can be carried out at low cost to the others Hardwood species become equal without
ίο die Kosten der Behandlung die erzielten Vorteile aufwiegen würden. Insbesondere wird diesen bisher nur als Brennholz verwerteten Holzarten die Eignung zum Werkholz verliehen und außerdem ermöglicht, daß selbst das frisch gefällte Holz sofort nach der an jedem Orte ohne besondere Einrichtung vorzunehmenden Behandlung, also ohne vorheriges Trocknen, verarbeitet werden kann, ohne daß nachträgliche Sprungbildungen zu befürchten wären.ίο the cost of the treatment the benefits obtained would outweigh. In particular, these types of wood, which until now have only been used as firewood, are made suitable for wood and it also enables even the freshly felled wood to be done immediately after that in any place without any special facility Treatment, i.e. without prior drying, can be processed without fear of subsequent cracking would be.
