Verbesserungs-Patent zu Patent No. 2060 vom 25. December 1877. Patentirt im Deutschen Reiche vom 16. October 1879 ab.Improvement patent to patent no. 2060 of December 25, 1877. Patented in the German Empire on October 16, 1879.
Die Verbesserung soll darin bestehen, dafs die Mischung von Seifenlösung mit Schwefelsäure vor dem Imprägniren geschieht.The improvement is said to consist in the mixture of soap solution with sulfuric acid happens before the impregnation.
Der Seifenlösung werden ungefähr 150 g Schwefelsäure pro Hektoliter Wasser zugesetzt. Um die Mischung der Schwefelsäure mit der Seifenlösung innig zu Stande zu bringen, mufs man beim Einrühren der Seife Sorge tragen, nur ungefähr zwei Dritttheil des zu verwendenden Wassers zu nehmen und die Schwefelsäure mit dem dritten Dritttheil zu verdünnen und dieses dann mit der vorher hergestellten Seifenlösung zu vermischen.About 150 g of sulfuric acid per hectolitre of water are added to the soap solution. In order to bring about the intimate mixture of the sulfuric acid with the soap solution, one must care should be taken when stirring in the soap that only about two-thirds of the amount to be used is to be used To take water and to dilute the sulfuric acid with the third third part and this then mix with the previously prepared soap solution.
Der Erfinder behauptet nun, dafs, so lange die Schwefelsäure (oder ein anderes Reagens) in starker Verdünnung die Seifenlösung nicht zersetzt, aber wenn nach der Injicirung dieThe inventor now asserts that as long as sulfuric acid (or another reagent) the soap solution does not decompose in strong dilution, but if it does so after the injection
Verdampfung hinreichend das Wasser verringert hat, ihre Reactionskraft wieder erlangt und die im Holz zurückbleibende Seifenlösung zersetzt und eine ölige Emulsion niederschlägt, die in die Fasern des Holzes eindringt bezw. sie umgiebt. Evaporation has sufficiently reduced the water, regained its reactive power and the Soap solution remaining in the wood decomposes and an oily emulsion precipitates, which in the fibers of the wood penetrate respectively. surrounds them.
Die niedergeschlagene Fettsäure soll als unlöslich im Wasser, antiseptisch und aufserdem insectenvertreibend sein; die Unlöslichkeit die Auslaugung verhindern.The precipitated fatty acid is said to be insoluble in water, antiseptic and besides be insect repellant; the insolubility prevent leaching.
