Patentirt im Deutschen Reiche vom 15. Juli 1898 ab.Patented in the German Empire on July 15, 1898.
Vorliegendes Verfahren bezweckt die Herstellung eines trockenen Magnesiacementes aus den Grundbestandtheilen Chlormagnesium, Magnesiumsilicat und gebranntem Magnesit mit oder ohne Zuthaten, wie Alkalicarbonat und dergl., in der Weise, dafs Lösungen von Chlormagnesium und Wasserglas zusammen innig vermischt, die ganze Masse nach erfolgter chemischer Umsetzung durch Eindampfen zur Trockne gebracht und in gepulvertem Zustande mit gebranntem gepulvertem Magnesit zu einem staubtrockenen, jederzeit gebrauchsfähigen und wirksamen Cemente vermengt wird.The present process aims to produce a dry magnesia cement the basic ingredients chlorine magnesium, magnesium silicate and burnt magnesite with or without additives, such as alkali carbonate and the like, in such a way that solutions of chloromagnesium and water glass are intimately mixed together, the whole mass after the chemical reaction has taken place by evaporation Brought dry and powdered with burnt powdered magnesite mixed to a dust-dry, always usable and effective cement will.
Das Wesentliche des neuen Verfahrens beruht in der Gewinnung des trockenen Chlormagnesium - Wasserglasgemenges durch Abdampfen der vereinigten und zur gegenseitigen Einwirkung gebrachten Lösungen. Die Mengenverhältnisse der beiden Lösungen sind so zu wählen, dafs ein Theil des Chlormagnesiums unzersetzt im Ueberschufs verbleibt, während der andere Theil (etwa die Hälfte bis zwei Drittel) desselben in Magnesiumhydrosilicat und Alkalichlorid umgesetzt wird.The essence of the new process is based on the extraction of the dry magnesium chloride - Water glass mixture by evaporation of the combined solutions brought into mutual action. The proportions of the two solutions are to be chosen so that a part of the magnesium chloride remains undecomposed in the excess, while the other part (about half to two Third) of the same is converted into magnesium hydrosilicate and alkali chloride.
Während reines Chlormagnesium sich sehr schwer und kaum ohne Zersetzung bis zur staubförmigen Trockne eindampfen läfst, wird dieser Zweck bei vorgenannter Mischung ohne jede Schwierigkeit erreicht. Dies erklärt sich einestheils durch die Gegenwart des Magnesiumhydrosilicats und andererseits durch die Wirkung des gebildeten Alkalichlorids, welches mit Chlormagnesium ein beständiges Doppelsalz bildet. Zudem besitzt dieses Trockengemisch den Vorzug, dafs sowohl das Chlormagnesium wie auch das Magnesiumsilicat infolge ihres unveränderten hydratischen Zustandes ihre cementirenden Eigenschaften mit Bezug auf gebrannten Magnesit beibehalten und vereinigt zur Geltung bringen. Es hat sich ergeben, dafs das in dieser Weise hergestellte trockene Cementpulver beliebig lange ohne Feuchtwerden aufbewahrt werden kann und nach dem Anmachen mit Wasser eine überaus grofse Festigkeit und Härte erlangt. Gleicherzeit ist die Eigenschaft des Chlormagnesiums, aus der Luft Wasser aufzunehmen, völlig beseitigt, so dafs ein nachträgliches Schwitzen des Cementes nicht eintritt. Diese Wirkung ist zurückzuführen einestheils auf den durch die Umsetzung mit Wasserglas verminderten Bestand an Chlormagnesium, sowie insbesondere durch die Bildung eines Doppelsalzes aus dem überschüssigen Chlormagnesium mit dem aus der Umsetzung hervorgegangenen Alkalichlorid, dessen cementirende Wirkung die des reinen Chlormagnesiums übersteigt. Von hervorragender Wirksamkeit erweist sich zudem das in obiger Weise gebildete und zur Trockne gebrachte Magnesiumsilicat der Mischung, indem dasselbe die Kieselsäure in einem derartig günstig aufgeschlossenen hydratischen Zustande enthält, dafs unter dem gleichzeitigen Einflufs des Chlormagnesiums die erhärtende und cementirende Wirkung der Kieselsäure auf den gebrannten Magnesit in hohem Grade sich geltend macht. Diesbezügliche Versuche zeigten, dafs nur das in obiger Weise gewonnene Gemisch von Chlormagnesium und Silicat die Festigkeit der damit hergestellten Gegenstände in solchem Mafse günstig' beeinflufst, während z. B. dieWhile pure magnesium chloride is very difficult and hardly without decomposition up to allows to evaporate dust-like dryness, this purpose is without the aforementioned mixture without every difficulty achieved. This is partly explained by the presence of the magnesium hydrosilicate and on the other hand through the action of the alkali metal chloride formed, which, with chlorine magnesium, forms a stable double salt forms. In addition, this dry mixture has the advantage that both chlorine magnesium as does magnesium silicate because of their unchanged hydrate state cementing properties with respect to burnt magnesite retained and combined bring to bear. It has been found that the dry substance produced in this way Cement powder can be stored for any length of time without getting wet and, after mixing with water, a very large one Gaining strength and hardness. At the same time is the property of magnesium chloride from which Air absorbing water is completely eliminated, so that subsequent sweating of the cement does not occur. This effect is partly due to the implementation with Water glass reduced the amount of chlorine magnesium, and especially due to the formation of a double salt from the excess Magnesium chlorine with the alkali metal chloride resulting from the reaction, the cementing effect of which is that of the pure Chlorine Magnesium Exceeds. The in Magnesium silicate of the mixture formed above and brought to dryness by adding the same is the case with silica in such a favorable hydrate state contains that under the simultaneous influence of magnesium chloride the hardening and cementing The effect of silica on the burnt magnesite is highly evident. Experiments in this regard have shown that only the mixture of chloromagnesium and silicate obtained in the above manner has the strength the objects produced therewith to such an extent favorably 'influenced, while z. B. the

Verwendung der beiden Bestandtheile in frisch gefälltem, nicht getrocknetem oder aber in gesondert gewonnenem und nachträglich gemischtem Zustande eine Beeinflussung in obigem Sinne nicht erkennen lassen.Use of the two components in freshly felled, undried or separately obtained and subsequently mixed states do not reveal an influence in the above sense.
Es unterscheidet sich demgemäfs vorstehendes Verfahren von den bekannten bisherigen Verfahren der Mitverwendung von Silicaten dadurch, dafs eine gemeinschaftliche Eindampfung von Chlormagnesium und Wasserglas bis zur Trockne vorgenommen und das so erhaltene Gemisch von Chlormagnesium, Alkalichlorid und Magnesiumsilicat in trockener Form mit gebranntem Magnesit zu einem selbst nach langer Zeitdauer gebrauchsfähigen trockenen und höchst wirksamen Cementpulver verarbeitet wird.Accordingly, the above method differs from the known previous methods the use of silicates by the fact that a common evaporation made of chlorine magnesium and water glass to dryness and the resulting mixture of chlorine magnesium, Alkali chloride and magnesium silicate in dry form with burnt magnesite to one Dry and highly effective cement powder that can be used even after a long period of time is processed.
