Description

Verfahren zur Gewinnung eines mit Wasser abbindenden mittels aus Anhydrit. Zusatz zum Patent 376oor. Gegenstand der Erfindung ist eine weitere Ausbildung des Verfahrens nach dem Hauptpatent 376ooi.Process for obtaining a water-setting agent from anhydrite. Addition to the 376oor patent. The invention is a further embodiment of the Procedure according to the main patent 376ooi.

Es hat sich herausgestellt, daß das Trocknen nach dem Verfahren des Hauptpatents auch bei höheren Temperaturen als ioo° durchgeführt werden kann. Solche Temperaturen werden zweckmäßig angewendet, wo entsprechende Wärmequellen zur Verfügung stehen. Der Trocknungsvorgang wird durch Anwendung höhererTemperaturenbeschleunigt, und das Erzeugnis hat im wesentlichen die gleichen Eigenschaften wie nach dem Verfahren des Hauptpatents.It has been found that drying by the method of Main patent can also be carried out at temperatures higher than 100 °. Such Temperatures are expediently used where appropriate heat sources are available stand. The drying process is accelerated by using higher temperatures, and the product has essentially the same properties as after the process of the main patent.

Die Temperaturgrenzen wechseln bei den verschiedenen Anhydritsorten, ähnlich wie dies bei dem üblichen Brennen des Gipses der Fall ist.The temperature limits change with the different types of anhydrite, similar to the usual firing of plaster of paris.
