Zusatz zum Patent 237728 vom 22. Januar igii.Addendum to patent 237728 from January 22nd igii.
Patentiert im Deutschen Reiche vom 1. April 1911 ab. Längste Dauer: 21.Januar 1926.Patented in the German Empire on April 1, 1911. Longest duration: January 21, 1926.
In der Patentschrift 237728 ist ein Verfahren beschrieben, einen fäulnisbeständigen Schutzüberzug auf Tonwaren aus einem Gemenge von Leimlösung und dem Kondensationszwischenprodukt von Phenolen und Aldehyden herzustellen. Der Ausblühungen verhindernde Überzug wird in bekannter Weise als Brühe aufgebracht. Aus dieser bildet sich beim Verdunsten des Wassers der deckende, zusammenhängende Belag. Da dieses in der feuchten Atmosphäre der oft dumpfigen, mit frischen Ziegeln belegten Trockenräume noch ziemlich lange dauert, tritt doch bisweilen eine geringe Zersetzung des Leimes ein.In the patent specification 237728 a method is described, a rot-resistant one Protective coating on pottery made from a mixture of glue solution and the intermediate condensation product of phenols and aldehydes. The anti-efflorescence coating is applied in a known manner applied as a broth. When the water evaporates, this forms the covering, contiguous covering. Since this in the humid atmosphere of the often dull, with Drying rooms covered with fresh bricks still lasts quite a long time, as one sometimes occurs little decomposition of the glue.
Der Erfinder führt deshalb den Aufguß sofort in eine harzähnliche Masse über, was durch Zugabe gewisser Salze zu der Begußmasse gelingt. Infolge der Bildung einer Harzschicht schaden nämlich Salze jetzt nicht mehr.The inventor therefore leads the infusion immediately into a resin-like mass, what succeeds by adding certain salts to the casting compound. Due to the formation of a resin layer Salts no longer do any harm.
Überdies können die Salzmassen ganz gering seih. Bewährt haben sich Sulfate, Bisulfate, Oxalate, daneben auch noch andere Salze der Erdalkalien und der Erden, besonders des Bariums, Magnesiums, Zinks, z. B. Bariumchlorid, Bariumnitrat, Bariumkarbonat, Magnesiumchlorid, Zinkfluat.In addition, the salt masses can be very small. Sulphates, bisulphates, Oxalates, as well as other salts of the alkaline earths and the earths, especially des Barium, magnesium, zinc, e.g. B. barium chloride, barium nitrate, barium carbonate, magnesium chloride, Zinc fluate.
Einige Salze wirken so schnell verharzend, daß sich bald nach dem Zusammenmischen Ausscheidungen bilden; so wirken vor allem Kupfersulfat, Bariumnitrat und Salze schwacher Säuren, z. B. Oxalsäure. In dem Falle arbeitet man zweckmäßig so, daß zuerst auf die Ziegel ein Beguß mit einem Gemenge von Leimlösung und Phenolaldehyd-Kondensationsprodukt aufgebracht und darüber eine zweite Lösung eines der genannten Salze gegeben wird. Die Wechselwirkung der beiden Flüssigkeiten veranlaßt die Entstehung einer gleichmäßigen Haut auf den Ziegel, während das überschüssige Wasser noch vorhanden ist. Anstatt der Salze können auch verdünnte Säuren gebraucht werden.Some salts resinify so quickly that they become resinous soon after mixing Form excretions; copper sulphate, barium nitrate and salts in particular have a weaker effect Acids, e.g. B. oxalic acid. In that case it is advisable to work in such a way that first on the bricks a cast with a mixture of glue solution and phenolaldehyde condensation product applied and over it a second solution of one of the salts mentioned is given. The interaction of the two liquids causes an even skin to form on the brick while the excess water is still present. Instead of Diluted acids can also be used for the salts.
Durch die Salzzusätze wird die Beständigkeit des Überzuges noch vergrößert.The resistance of the coating is increased by the addition of salt.
An Stelle des Leimes oder neben ihm können bei der neuen Begußmasse auch andere organische Kolloide, wie Stärke, Mehl, Gummi, genommen werden.In place of the glue or in addition to it, others can also be used for the new casting compound organic colloids, such as starch, flour, gum, can be taken.
