Description

Verfahren zur Herstellung von wasserfesten Wasserglasmassen Zusatz zum Patent 636 054 Weitere Versuche und praktische Ergebnisse unter Benutzung des in der Patentschrift 636054 beschriebenen, Verfahrens haben ergeben, daß der Zusatz von Metallacetaten zu. Wasserglas bestimmten Beschränkungen unterliegt. Die Wasserfestigkeit eines Formlings bedingt die Zumischung einer bestimmten Acetatmenge zum Wasserglas. Nimmt man eine Lösung des Acetats über 3 %, so besteht die Gefahr einer zu raschen . Gelbildung. Diese Gefahr und eine erschwerte Verarbeitung werden auch bei hochprozentigen Acetatlösungen beseitigt, wenn dem Wasserglas außer der erwünschten hochprozentigen Acetatlösung auch ein Metallfluorid beigemischt wird. Es ist bekannt, daß der Zusatz von Fluoriden zu Wasserglasmassen zur Bindung, Härtung und Säurefestigkeit führt. Diese bekannten Wirkungen von Fluoriden ergeben nun zusammen mit den Wirkungen von Acetatzusätzen nach dem Hauptpatent zum Wasserglas den technischen Fortschritt, daß man die gewünschte Wasserglasemulsion durch hochprozentige Acetatlösung in Verbindung mit einem Zusatz von Metallfluorid ohne vorzeitige Gel-Bildung, ohne schädliche Ausscheidungen lange Zeit lagerfähig und leicht verarbeitbar erhält.Process for the production of water-resistant water glass masses Addition to patent 636 054 Further experiments and practical results using the process described in patent 636054 have shown that the addition of metal acetates to Water glass is subject to certain restrictions. The water resistance of a molding requires the addition of a certain amount of acetate to the water glass. If you take a solution of the acetate above 3%, there is a risk of it being too rapid. Gel formation. This danger and difficult processing are eliminated even with high-percentage acetate solutions if a metal fluoride is added to the water glass in addition to the desired high-percentage acetate solution. It is known that the addition of fluorides to water glass compounds leads to bonding, hardening and acid resistance. These known effects of fluorides, together with the effects of acetate additives according to the main patent for water glass, result in the technical progress that the desired water glass emulsion can be stored for a long time by means of a high percentage acetate solution in conjunction with an addition of metal fluoride without premature gel formation, without harmful excretions easy to process.

Man bringt die Metallacetatlösung mit einem beliebigen Metallfluorid stufenweise in das Wasserglas, wobei man die Mengen und Lösungsgrade beider Zusätze in beliebigen Grenzen, dem jeweiligen Verwendungszweck angepaßt, halten kann. Bei der Verarbeitung mit gut reagierenden Mineralien ist durch die Vereinigung von Acetat und Fluarid die be= sonders günstige Wirkung aufeinander und in ihrer Vereinigung auf die Wasserglasmasse auch dadurch .ausgezeichnet; daß der bereitete Wasserglasmörtel nicht vorzeitig erhärtet, also bequem' zu verarbeiten ist und schon nach kurzer Abbindezeit große Härte und Wasserfestigkeit erreicht.Bring the metal acetate solution with any metal fluoride gradually into the water glass, taking into account the amounts and degrees of solution of both additives can hold within any limits, adapted to the respective purpose. at The processing with well-reacting minerals is due to the Union of acetate and fluoride the particularly favorable effect on each other and in their own Association on the water glass mass also because of this. that he prepared Water glass mortar does not harden prematurely, so it is easy to process and does Great hardness and water resistance achieved after a short setting time.
