Description
KAISERLICHESIMPERIAL
Eines der bekanntesten Mittel zum Schütze des Holzes gegen Trockenfäule u. dgl. ist das Merkurichlorid. Es zeichnet sich besonders durch die Eigenschaft aus, vom Holze gut fixiert zu werden. Dieses Verhalten beruht augenscheinlich darauf, daß das Merkurichlorid einerseits mit der Holzfaser, andererseits mit den Eiweißverbindungen unlösliche Körper bildet, die aus dem Holze nicht ausgelaugt ίο werden können. Die ausgefällten Eiweißverbindungen schließen aber gleichzeitig auch einen Teil des Merkurichlorides unverändert in sich ein, wodurch es diesem wegen mangelnden Feuchtigkeitszutrittes unmöglich gemacht wird, hinreichend antiseptisch zu wirken. One of the best-known means of protecting wood against dry rot and the like is that Mercury chloride. It is particularly characterized by the property of being made of wood to be fixed. This behavior is apparently based on the fact that the mercury chloride on the one hand with the wood fiber, on the other hand with the protein compounds insoluble bodies forms that cannot be leached from the wood ίο. The precipitated protein compounds but at the same time also include a part of the mercury chloride unchanged, making it due to the lack of it Moisture access is made impossible to have a sufficiently antiseptic effect.
Wie nun gefunden worden ist, gelingt es, diesen Ubelstand dadurch zu beheben, daß das Merkurichlorid in komplexe Salze übergeführt wird, die unter anderem die Eigenschaft haben, Eiweiß nicht zu koagulieren.As has now been found, it is possible to remedy this deficiency in that the mercury chloride is converted into complex salts, which among other things have the property have not to coagulate protein.
Solche komplexen Verbindungen lassen sich, was bisher noch nicht bekannt war, überraschenderweise .durch Zusatz von Fluorsalzlösungen herstellen.Such complex compounds can surprisingly, which was not previously known . Produce by adding fluorine salt solutions.
Mischt man beispielsweise 0,Teile einer o,6prozentigen Fluornatriumlösung mit 6,5 Teilen einer o,6prozentigen Merkurichloridlösung, so hat das Lösungsgemisch im Gegensatz zu reiner !3o Merkurichloridlösung die Fähigkeit verloren, Eiweiß namentlich der Milch zu koagulieren. Sogar längeres Kochen bleibt einflußlos.For example, if you mix 0. part of a 0.6 percent sodium fluoride solution with 6.5 parts of a 0.6 percent mercury chloride solution, the mixed solution, in contrast to pure ! 30 Mercury chloride solution has lost the ability to coagulate protein, especially in milk. Even prolonged cooking remains unaffected.
Durch . weiteren Zusatz von Fluornatrium, wie beispielsweise 12 oder 18 Teilen Fluornatrium zu 6,5 Teilen Merkurichlorid, tritt eine weitere Steigerung der Komplexbildung ein, wie das bleibende Unvermögen, Milch selbst bei Siedehitze zum Gerinnen zu bringen, zeigt.By . further addition of fluorosodium, such as 12 or 18 parts of fluorosodium to 6.5 parts of mercury chloride, a further increase in complex formation occurs, as shown by the persistent inability to curdle milk even at boiling point.
Die Einführung der zweckmäßig 1- bis 2prozentigen Imprägnierlösungen in das Holz geschieht entweder als Anstrich oder in geeignet gebauten Tränkbottichen oder Kesseln nach einer der üblichen Methoden der Holzkonservierung. Die Imprägnierung kann auch in zwei getrennten Operationen und derart ausgeführt werden, daß das Holz zuerst mit der Fluorsalzlösung und dann mit der Merkurichloridlösung behandelt wird. ■ The introduction of the expedient 1 to 2 percent Impregnation solutions in the wood are done either as a paint or in suitably built soaking tubs or kettles according to one of the usual methods of wood preservation. The impregnation can also in two separate operations and in such a way that the wood comes first with the fluorine salt solution and then with the mercury chloride solution. ■
Statt der reinen Fluorsalzlösungen lassen sich auch entsprechende Gemische von Fluormit Kieselfluorverbindungen verwenden.Instead of the pure fluorine salt solutions, corresponding mixtures of fluoromite can also be used Use silica fluorine compounds.
