  Verfahren zur Herstellung von Formlingen aus Alkalisilikaten.

   zur Aufbewahrung   und zum Versand nötigen Gefässe immer gewisse Nachteile gegenüber der festen Form. 



  Dieses trifft besonders bei den klebrigen   Alkalisilikatlosungen zu,   die gerade wegen ihrer Klebrigkeit schwer abzumessen sind. 



   Der   übliche   Weg, aus solchen pulverförmigen Stoffen Presslinge zu erzeugen, der darin besteht, die Pulver einem starken Drucke auszusetzen, führte nicht Ziele. Die teuern und langsam arbeiten- den Pressen, die zur Erzielung der Formlinge notwendig waren, versagten in dem   vorliegenden Falle,

 so zeigt es sich, dass dieser durch eine einfache Behandlung bereits eine ausserordentliche mechanische
Festigkeit angenommen hat, und nahezu unzerbrechlich geworden ist, obwohl er im Innern noch aus ziemlich losem Pulver besteht und nur eine wenige Millimeter starke, sehr hart aligebundene Aussen- schiebt erhalten hat.

     Die. nach dem neuen Verfahren erhaltenen Foimlinge   bieten praktisch sehr grosse Vorteile. sie sind in Aufbewahrung und Anwendung handlich und können ferner in Gewicht und Form den verschiedenen   Verwendungszwecken angepasst   werden, so dass der Verbraucher nur noch eine bestimmte Anzahl Stücke für einen bestimmten Verwendungszweck in Wasser aufzulösen braucht. 



   Die gleichen Vorteile erreicht man nicht, wenn man Lösungen von Alkalisilikaten einfach in Formen 
 EMI2.1 
 nicht unversehrt entfernt werden kann.   In solchen Fällen entstehen auch   nur harte Körper, die sieh nur schwer wieder in Wasser auflösen lassen. 



   Es ist bereits bekannt, durch starkes Erhitzen von pulverförmigen   unlöslichen   Silikaten mit Wasser harte Kuchen aus löslichem Alkalisilikat zu erhalten. Demgegenüber wird bei dem vorstehenden Verfahren von   pulverförmigen   löslichen Silikaten ausgegangen, die ohne Anwendung von Wärme mit den die Abbindung bewirkenden Flüssigkeiten (Wasser oder verdünnte   Alkalisilikatlösungen)   vermengt werden. Es entstehen hiebei ohne Anwendung starkwirkender Pressen handliche Formlinge, in denen die   Wasserlösliehkeit   der Silikate nicht beeinträchtigt worden ist.

  Process for the production of moldings from alkali silicates.
 EMI1.1
   The vessels required for storage and shipping always have certain disadvantages compared to the solid form.



  This applies particularly to the sticky alkali silicate solutions, which are difficult to measure precisely because of their stickiness.



   The usual way of producing compacts from such powdery substances, which consists in subjecting the powder to strong pressure, did not lead to goals. The expensive and slow-working presses that were necessary to obtain the bricks failed in the present case,

     The. Foimlings obtained by the new process offer very great advantages in practice. they are easy to store and use, and their weight and shape can also be adapted to the various uses, so that the consumer only needs to dissolve a certain number of pieces in water for a certain use.



   The same advantages cannot be achieved by simply putting solutions of alkali silicates in forms
 EMI2.1
 cannot be removed intact. In such cases only hard bodies are formed that are difficult to dissolve in water.



   It is already known that hard cakes of soluble alkali silicate can be obtained by vigorously heating powdered insoluble silicates with water. In contrast, the above method is based on soluble silicates in powder form, which are mixed with the setting liquids (water or dilute alkali metal silicate solutions) without the use of heat. Without the use of strong presses, manageable moldings are produced in which the water solubility of the silicates has not been impaired.
