Description
Verfahren zur Herstellung selbsthärtender und säuredichter Wasserglaskitte In der Säurebautechnik werden in großem Umfange selbsterhärtende säurefeste Wasserglaskitte benutzt. Solche Kitte werden durch Vermischen von flüssigen Natronwasserglaslösungen und Kittmehlen mit einem Gehalt an alkalireaktionsfähigen Zusatzstoffen erhalten. Der Hauptnachteil dieser bekannten Säurekitte liegt darin, daß es nicht möglich ist, mit ihnen säuredichte Kittungen oder Mauerungen auszuführen. Die durch einen Gehalt von Alkalisilicaten in löslicher Form und von alkalireaktionsfähigen Zusatzstoffen, z. B. Alkali- oder Erdalkalisilicofluoriden, gekennzeichneten Kittmassen und Mörtel erhärten unter Luftabschluß zwar selbst, sind aber nicht säuredicht.Process for the production of self-hardening and acid-proof water glass cements In acid building technology, self-hardening, acid-resistant water glass putties are used on a large scale used. Such putties are made by mixing liquid soda waterglass solutions and cement flours with a content of alkali-reactive additives. The main disadvantage of these known acid putties is that it is not possible is to use them to carry out acid-tight putty or masonry. The through one Content of alkali silicates in soluble form and alkali-reactive additives, z. B. alkali or alkaline earth metal silicofluorides, marked putty and mortar harden themselves in the absence of air, but are not acid-tight.
Es wurde nun gefunden, daß eine ganz außerordentliche Verbesserung dieser selbsterhärtenden Säurekitte erreicht werden kann, falls man ganz bestimmte Maßnahmen bei der Herstellung vereinigt, und zwar neben dem Zusatz an sich bekannter alkalireaktionsfähiger Stoffe einerseits die Wasserglaslösungen besonders auswählt und gleichzeitig den Mörteln oder Kitten besonders aktive Kieselsäure zusetzt. Diese Kieselsäure muß ganz besonders alkalireaktionsfähig sein und sich bereits in kalten Alkalilaugen läsen. Besonders gute Ergebnisse wurden dadurch erhalten, daß man für die obige Zusammenstellung eine aktive Kieselsäure anwendet, die aus der Zersetzung von Siliciumverbindungen, und zwar insbesondere aus der Zersetzung von Siliciumfluorverbindungen, stammt. Man ist durch den Zusatz dieser Kieselsäuresorten in der Lage, beim Anmachen in den Wasserglaslösungen das Mengenverhältnis von H20 : S102 besonders hoch zu treiben. Mit diesem Hilfsmittel hat man es also in der Hand, auch sehr wasserreiche Wasserglaslösungen zur Herstellung von säuredichten Kittungen zu verwenden. Die wasserreichen Wasserglaslösungen haben technisch den Vorteil, daß sie sehr dünnflüssig sind und dadurch die Verarbeitung der Kittmassen erheblich erleichtert wird. Insbesondere kann man gießfähige Massen damit herstellen. Die erfindungsgemäß verwendeten Wasserglaslösungen haben ein Mengenverhältnis von Nag O : Si 02 wie ' I : I bis I : 2 I : 2 bis I : 3 über I : 3 und gleichzeitig von Si02 :IH20 wie I : I,5 bis i : 4 oder I : I,5 bis I :2,5 oder I:I,5 bis I :2,0.It has now been found that an extraordinary improvement These self-hardening acid putties can be achieved if you have very specific ones Measures in the production combined, namely in addition to the addition known per se Alkali-reactive substances, on the one hand, which specifically selects waterglass solutions and at the same time adding particularly active silica to the mortars or putties. These Silicic acid must be particularly alkali-reactive and already in cold Let alkaline solutions. Particularly good results have been obtained by for The above compilation uses an active silica that results from the decomposition of silicon compounds, in particular from the decomposition of silicon fluorine compounds, originates. By adding these types of silicic acid, you are able to start mixing in to drive the ratio of H20: S102 particularly high in the water glass solutions. With this aid you have it in hand, even water glass solutions that are very rich in water to be used for the production of acid-tight putty. The water-rich water glass solutions have the technical advantage that they are very thin and therefore the processing the putty is made considerably easier. In particular, you can castable masses manufacture with it. The water glass solutions used according to the invention have a quantitative ratio from Nag O: Si 02 like 'I: I to I: 2 I: 2 to I: 3 through I: 3 and at the same time from SiO2: IH20 such as I: 1.5 to i: 4 or I: 1.5 to I: 2.5 or I: 1.5 to I: 2.0.
Wenn , was in der Praxis meist der Fall sein wird, als alkalireaktiönsfähige und die Selbsterhärtung bewirkende Zusätze dem Kittmehl Silicofluoride beigemengt werden, empfiehlt es sich ferner, neben Alkalisilico-@luoriden noch Erdalkalisilicofluoride für diesen Zweck ztu verwenden.If, as will usually be the case in practice, as alkali-reactive and additives causing self-hardening are added to the putty flour Silicofluoride it is also advisable to use alkaline earth silicofluorides in addition to alkali metal silicofluorides ztu use for this purpose.
