Description

Wasserglaskitt IMe Güte eines Wasserglaskittes hängt ab von der Reaktionsfähigkeit der itn Kittmehl enthaltenen Silicate mit dem in der Wassergl'aslösung infolge Hydrolyse freien Alkali. Überschüssiges, d. h. mit den Si*,icaten (Kieselsäure) nicht in Reaktion getretenes Alkali scheidet sich besonders störend an der Oberfläche von Wasserglaskitt als hautförmige Kruste aus, wodurch die weitere Wasserverdunstung erschwert und die Zufuhr von Kohlensäure aus der Luft zu der tiefer liegenden Kittmasse verhindert wird. Die nicht in Reaktion ,getretenen Kittbestandteile machen außerdem den Kitt mehr oder weniger wasserlöslich.Water glass putty IMe quality of a water glass putty depends on the reactivity the silicates contained in cement powder with that in the water-glass solution as a result of hydrolysis free alkali. Excess, d. H. not in reaction with the Si *, icates (silicic acid) Any alkali that has entered separates on the surface of the water-glass putty, which is particularly disturbing as a skin-shaped crust, which makes further water evaporation more difficult and prevents the supply of carbonic acid from the air to the underlying cement mass will. The putty components that have not reacted also make the putty more or less soluble in water.

Man kennt in der Technik verschiedene Verfahren, die Reaktion der Kittmehle mit SVasserglas so zu steigern; daß Kittmassen wasserunlöslich und säurefest sind. Bei solchen Verfahren sind vorgeschriebene Grenzen der Reaktionsmittel zu beachten, weil sonst das Alkali des Wasserglases sich mit überschüssigen Säuren zu deren Salzen umsetzt.One knows in the art different processes, the reaction of the Increase putty flour with a water glass like this; that cement masses are water-insoluble and acid-resistant are. In such processes, prescribed limits for the reactants are imposed Note, because otherwise the alkali of the water glass will mix with excess acids converts to their salts.

Durch die Zusätze gemäß der Erfindung wird eine Beeinflussung des Hydrolysengl,eicbge-,vichtes hinsichtlich Ausscheidung von Kieselsäuregel in Wasserglas in neuartiger Weise gUinstig erreicht. Bekannt ist, daß jene stöchioanetrisch sauren Salze der Phosphorsäure, die nicht alkalisch reagieren, den Abbindevorgang im Wasser -glaskitt günstig beeinflussen. ohne jedoch den Wasserglaskitt wasserfest zu machen. Dies ist- z. B. .der Fall bei der bekannten Verwendung von primärem oder sekundärem Calciumphosphat. im Weiterv:erfolg dieser bekannten Vorgänge wurde nun gefunden, daß bei Verwendung von Tricalciumphosphat, insbesondere des afkalilöslichen, nicht nur .eine günstige Wirkung in der Steigerung oder Verminderung der gewünschten Abbindegeschwindigkeit des Kittes eintritt, also die. obenerwähnte schädliche Hautbildung auf der Kittoberfläche ausbleibt, sondern daß. die mit Zusatz von Tricalciumphosphat hergestellten Kitte auch wasserunlöslich sind, ohne daß die Säurefestigkeit, je nach der Zusammensc:tzung .des Bittmehles, beeinträchtigt wird.The additives according to the invention influence the Hydrolysengl, eicbge-, vichtes with regard to the excretion of silica gel in water glass Achieved inexpensively in a novel way. It is known that those stoichioanetrically acidic Phosphoric acid salts, which do not react alkaline, the setting process in the water - have a favorable effect on glass putty. but without making the water glass putty waterproof. This is- z. B. The case with the known use of primary or secondary Calcium phosphate. in the continuation: success of these known processes has now been found that when using tricalcium phosphate, especially the afkali-soluble, not only. a beneficial effect in increasing or decreasing the desired setting speed of the putty occurs, so the. Above-mentioned harmful skin formation on the surface of the putty is absent, but that. the putties made with the addition of tricalcium phosphate are also insoluble in water, without the acid resistance, depending on the composition . of bitter flour, is impaired.

Ian Zusammenhang mit dieser überraschenden Feststellung wurde eine ähnliche Wirkung erzielt durch Zusatz von Aluminiumtriformiat. Während die bekannte Wirktang von Metallacetaten dadurch beeinträchtigt wird, daß solche dem Wasserglas nur in beschränkter Menge und vorsichtig beigefügt werden dürfen. kann man der Kittmischung Aluminiumtriforrni;a in wesentlich ;weiterer) Grenzen beifütgen. ohne daß vorzeitige Gel- bildun;g eintritt. Bringt man z. ß. zum Wasserglas eine Lö.., sung von Aluminitrmtriformiat und gibt (fi(=;z.i Kittmehl einen Zusatz von Tricalciumphospll@lt:' so wirken diese beiden Zusätze nicht gege# -- einander, sondern günstig miteinander auf' die Abbindung, Festigkeit und Wasserunlös- lichkeit ein. ohne daß die Säurefestigkeit, je nach Zusammensetzung des Kitthehles be- einträchtigt wird. Tricalciumphosphat und Aluminiunitrifor- miat können ülso einzeln jeweils für sich oder in beliebiger Wechselwirkung bei der Herstellung von Wasserglaskitt verwendet erden. - :X. u s f ü h Y Lt Il g s b- e t s p 1 (-I c- l' as bekannte Kittmehl aus Feldspat und Tonerd-rhält eine -Beimischung voll -I o -bis i 5 Ge@vichtstcilen des primären oder sekun- dären r"alcitllnpllospllats. Der hiermit be- reitete Wasserglaskitt zeigt nach seiner Ab- bindung usblühun-en und ist nicht «wasser- fest. g=ibt lnan d(-.m @ orgenannten Kitttnelll eine I-jcimisellullg von t o bis 15 Gewichts teile,) t oll Tricalciumphosphat, so zeit (ler mit -W-AAsserglas bereitete Kitt keine Aus- blühunnen und -wird für gewöhnliche Zweckc ,;@@-.1sse rfe st. :' :-Man kann aber auch Tricalciumphosphat --'meiner wäßrigen Dispersion, ebenfalls etwa @: l@ö bis I g -Gewichtsteile, dem Wasserglas bei - mischen und dann erst den Kitt bereiten. Vermischt man mit dem `'Wasserglas auch noch eine ',G-aßrhe Eis pel:slon von b15 l o Gewichtsteilen Aluminiumtriformiat, so wird das ber<hete Kittmehl merklich «-asser- fester. Soll außerdem der Wasserglaskitt auch säurefest werden, so sind Kittmehle zu ver- u-enden, die in bekannter Weise selbst säure- fest sind. Die in @ orgenannten Beispielen erwähnten Mischungsverhältnisse können natürlich nach oben o(ic r nach unten geändert E;-erden. In connection with this surprising finding, a similar effect was achieved by adding aluminum triformate. While the well-known effectiveness of metal acetates is impaired by the fact that they may only be added carefully and in limited quantities to the water glass. you can use the putty mixture Aluminum triforrni; a in essential; further) Include borders. without premature gel education entry. If you bring z. ß. to the water glass a solution, solution of aluminum triformate and gives (fi (=; zi Kittmehl an addition of Tricalciumphospll @ lt: ' so these two additives do not work against # - each other, but favorably with each other ' the setting, strength and water-insolubility opportunity a. without the acid resistance, necessary, depending on the composition of Kitthehles is affected. Tricalcium phosphate and aluminum nitrate miat can do ülso individually for themselves or in any interaction with the Used in the manufacture of water glass putty earth. -: X. usf ü h Y Lt Il gs b- etsp 1 (-I c- l ' as well-known putty flour made from feldspar and Alumina contains an admixture of full -I o -bis i 5 weights of the primary or secondary daren r "alcitllnpllospllats.
