Description
Verfahren zur Herstellung von säurefesten Kittungen Für die Herstellung von säurefesten Wässerglaskitten wird im allgemeinen die handelsübliche Natronwasserglaslösung vom spiez. Gewicht 433 bis 1,36 (36 bis 38° B6) und einem Molekularverhältnis von Nag O : Si 0z wie 1:3,q. verwendet. Es ist eine bekannte-. Tatsache, daß die Kittungen aus allen Wasserglaskitten darunter leiden, daß sie relativ leicht flüssigkeitsdurchlässig sind, so daß man bei allen Säurebauten auf die Anwendung von Isolierschichten angewiesen ist.Process for the production of acid-resistant putties For the production of acid-resistant water glass putties, the commercially available soda water glass solution from the spiez. Weight 433 to 1.36 (36 to 38 ° B6) and a molecular ratio of Nag O: Si Oz such as 1: 3, q. used. It's a well-known one. The fact that the putties from all water glass putties suffer from the fact that they are relatively easily permeable to liquids, so that one has to rely on the use of insulating layers in all acidic structures.
Es wurde nun gefunden, daß man eine erhebliche Steigerung der Flüsisigkeitsdichte bei Wasserglaskitten erreichen kann, falls man darauf achtet, daß zum Anmischen vorn an sich bekannten selbsterhärtenden Mörtelmehlen solche Wassergla.slösungen, verwendet werden, bei denen das Verhältnis von Kieselsäure zu Wasser größer ist als 1:2,.5. Durch umfangreiche Versuche wurde festgestellt, daß die besten Ergebnisse mit solchen: Wasserglaslösungen erzielt werden, bei denen das Verhältnis von Kieselsäure zu Wasser auch noch größer als i:2,o, ,am besten zwischen 1:1,5 und i : 2,o ist.It has now been found that there is a considerable increase in the liquid density with water glass kittens, if one makes sure that for mixing self-hardening mortar flours known per se such water-glass solutions, in which the ratio of silica to water is greater as 1: 2, .5. Extensive experimentation has been found to give the best results with such: water glass solutions can be achieved in which the ratio of silica to water is also greater than i: 2, o, best between 1: 1.5 and i: 2, o.
Wenn auch durch die Verwendung derartiger W@sserglaslösungen an sich unter Umständen etwas größeiie Mengen vom Alkaliverbind:ungen in die Wasserglaskittwngen gel,aggen, so hat @es sich doch gezeigt, daß das in dem Kieselgel enthaltene Wasser aus der Wasserglaslösung bei -dem obengenannten Mengenverhältnis von Kieselsäure zu Wasser derartig fest gebunden wird, daß die mit solchem Wasserglas verarbeiteten Kitte entgegen allen Erwartungen praktisch undurchlässig für Flüssigkeiten sind.Albeit through the use of such water glass solutions per se possibly somewhat larger amounts of alkali compounds in the water-glass cement gel, aggen, it has been shown that the water contained in the silica gel from the water glass solution with the above-mentioned quantity ratio of silica is so tightly bound to water that the processed with such water glass Contrary to all expectations, putties are practically impermeable to liquids.
Zweckmäßigerweisie werden bei der Herstel.-lung von selbsterhärtenden säure- und wasserfesten Mörteln, die im Mörtelmehl alkalireaktionsfähige Stoffe enthalten, außerdem noch solche Erhärtungsstoffe angewandt, die bei der Umsetzung mit dem Alkali der Wasserglaslösung selbst schwerlösliche Verbindungen bilden.Expediently, they are used in the manufacture of self-hardening acid- and water-resistant mortars that are alkali-reactive in the mortar powder Fabrics contain, in addition, those hardening substances used in the implementation form sparingly soluble compounds with the alkali in the water glass solution.
Beispiel g r, r g Quarzmehl werden mit 7,9 g Natriumsiliciumflworid und r g Calcium.siliciumfluorid vermengt und mit etwa 4o ccm einer Wasserglaslösu:ng vom spaz.llewicht r,43 und einem Verhältnis vorn Si02: H2 O wie r : 2,o bzw. einem Verhältnis. von Na20:Si02 wie 1:3,3 angemischt. Die Verarbeitungszeit der Kittmasse beträgt 1/4 Stunde. Die erhärteten Kitturigen sind praktisch flüssigkeitsundurchlässig und dabei säurebeständig.Example g r, r g of quartz flour are mixed with 7.9 g of sodium silicon fluoride and r g of calcium silicon fluoride and mixed with about 40 ccm of a water glass solution from the specific weight r, 43 and a ratio of Si02: H2 O like r: 2, o or one Relationship. of Na20: Si02 as 1: 3.3 mixed. The processing time of the putty mass is 1/4 hour. The hardened putties are practically impermeable to liquids and at the same time acid-resistant.
