Description

Verfahren zur Herstellung von Silikaten. Zweck des vorstehenden Verfahrens ist es, Silikate mit zerkleinerten Substanzen, wie Magnesiumoxyd; Calciumoxyd, Bariumoxyd, umzusetzen.Process for the production of silicates. Purpose of the above procedure is to silicates with crushed substances, such as magnesia; Calcium oxide, barium oxide, to implement.

Zu diesem Zweck wird gebrannte Magnesia oder gebrannter Kalk vermahlen und mit pulverförmigen Silikaten, wie künstliche Schlacken, Ziegelmehl, vulkanische Tuffe und ähnliche Stoffe, innig vermischt durch Zugabe von Wasser zum Ablöschen gebracht. Unter dem Einfluß der Löschwärme vermag das in Bildung begriffene Hvdroxvd die pulverförmigen Silikate aufzuschließen: Je nach der Menge des zugesetzten Wassers entsteht so ein pulver- oder schlammförmiges Material. Hierbei wurde gefunden, daß die oben beschriebene Wirkung der genannten Materialien noch gesteigert werden kann, wenn zur Einleitung des Prozesses der Kolloidbildung spurenweise andere Kolloide zugesetzt werden, welche als Beschleuniger wirken, wie z. B. kolloide Kieselsäure. Beispiel: 5o kg getrocknete Tuffasche wird mit etwa I2 kg Ca0 und I kg kolloide Kieselsäure versetzt und hierauf das Gemisch zwecks innigster Vermischung vermahlen, dann wird -11,- H.0, in dem 0,3 kg Wasserglas gelöst ist, zugesetzt und das Ganze innigst durch Riihren vermischt. Es entsteht ein trockenes Pulver; soll dasselbe dann als Schlamm erhalten werden, so wird je nach der gewünschten Konsistenz später weiter Wasser zugesetzt.For this purpose, burnt magnesia or burnt lime is ground and mixed with powdered silicates, such as artificial slag, brick flour, volcanic tuff and similar substances, intimately mixed with water and made to extinguish. Under the influence of the extinguishing heat, the Hvdroxvd, which is in the process of formation, is able to break down the powdery silicates: Depending on the amount of water added, a powdery or sludge-like material is created. It was found that the above-described effect of the materials mentioned can be increased if traces of other colloids are added to initiate the process of colloid formation, which act as accelerators, such as. B. colloidal silica. Example: 50 kg of dried tufa ash is mixed with about 12 kg of Ca0 and 1 kg of colloidal silica and then the mixture is ground for the most intimate mixing, then -11, - H.0, in which 0.3 kg of water glass is dissolved, is added and that Whole intimately mixed by stirring. A dry powder is produced; if the same is then to be obtained as a sludge, further water is added later, depending on the desired consistency.
