Description
Verfahren zur Herstellung von porösblasigen Klassen und Gegenständen Durch das Patent 572 259 ist ein Verfahren zur Herstellung porösblasiger Massen und Gegenstände durch Zusatz von Gas entwickelnden Stoffen zu abbindungsfähigen Stoffen, wie Zement, Gips u. dgl., unter Schutz gestellt. Nach diesem Verfahren wird die Erzeugung der Blasen rriit Hilfe von Sauerstoffgas bewerkstelligt, indem man den abbindungsfähigen Stoffen aktiven Sauerstoff abgebende Verbindungen, z. B. Wasserstoffsuperoxyd, Alkaliperborat u. dgl., und die Sauerstoffentwicklung bewirkende oder fördernde Stoffe, z. B. Zersetzungskatalysatoren, zusetzt. Im Rahmen dieses Verfahrens können den abbindungsfähigen Materialien. auch Zuschläge, Füllstoffe der üblichen Art, wie Sand, Kies, Korkpulver, Sägemehl u. dgl., einverleiht werden.Process for the production of porous-bubble classes and objects Patent 572 259 protects a process for the production of porous-bubble masses and objects by adding gas-evolving substances to substances capable of setting, such as cement, plaster of paris and the like. According to this process, the bubbles are produced with the aid of oxygen gas by adding compounds which give off active oxygen to the substances capable of being set, e.g. B. hydrogen peroxide, alkali metal perborate and the like. B. decomposition catalysts added. As part of this process, the hardenable materials. aggregates, fillers of the usual type, such as sand, gravel, cork powder, sawdust and the like, can also be added.
Es wurde nun gefunden, daß man die Form der erzeugten Blasen sowie die Wandstärke zwischen den Blasen und damit die Festigkeit der hergestellten Produkte wesentlich dadurch beeinflussen kann, daß man die Katalysatoren an die katalytisch selbst mehr oder minder unwirksamen Zuschlagsmaterialien, wie z. B. Sand, Kies, Kieselgur, Korkmehl, Sägemehl, Korkstücke u. dgl., bindet bzw. mit denselben vermengt und' sie in dieser Form in dem Gemisch von abbindungsfähigen Stoffen und aktiven Sauerstoff enthaltenden Substanzen zur Wirkung bringt.It has now been found that one can change the shape of the bubbles generated as well the wall thickness between the bubbles and thus the strength of the manufactured products can significantly influence the fact that the catalysts to the catalytically even more or less ineffective aggregate materials, such as. B. sand, gravel, Kieselguhr, cork flour, sawdust, pieces of cork and the like binds or is mixed with the same and 'them in this form in the mixture of settables and actives Brings oxygen-containing substances to effect.
In Durchführung dieser Abänderung des Verfahrens des Hauptpatents kann man z. B. derart verfahren, daß als Katalysatoren wirkende Stoffe mit den Zuschlagsmaterialien vereinigt und hierauf den abbindungsfähigen Stoffen oder deren Gemisch mit aktiven Sauerstoff enthaltenden Verbindungen einverleibt werden.In carrying out this amendment to the procedure of the main patent you can z. B. proceed in such a way that substances acting as catalysts with the aggregate materials combined and then the bindable substances or their mixture with active Oxygen-containing compounds are incorporated.
Ferner kann man z. B. auch derart verfahren, daß man Salze oder Verbindungen, welche katalytisch wirkende Substanzen durch Umsetzung mit geeigneten Reagenzien zu erzeugen imstande sind, gemeinsam mit den Zuschlagsmaterialien den abbindungsfähigen Stoffen bzw. deren Gemischen mit Sauerstoff abgebenden Substanzen zugibt und die Umsetzung nachträglich durch Zugabe der betreffenden Reagenzien bewirkt.Furthermore, you can z. B. also proceed in such a way that salts or compounds, which catalytically active substances by reaction with suitable reagents are able to produce, together with the aggregate materials, the bondable Adding substances or their mixtures with oxygen-releasing substances and the Implementation is effected subsequently by adding the relevant reagents.
So kann man z. B. die Zuschlagsmaterialien mit Lösungen von Katalysatoren liefernden Salzen oder Verbindungen tränken, das Gemisch in feuchtem Zustand oder nach vorheriger Trocknung den. abbindungsfähigen Materialien oder den sie enthaltenden Gemischen zumischen und darauf die Bildung der als Katalysatoren in Betracht kommenden Verbindungen, z. B. Oxyden, Hydroxyden o. dgl., durch Zusatz geeigneter Verbindungen, z. B. Natriumhydroxyd, Soda, Kalk, Ammoniak o. dgl., sei es in gelöster oder in aufgeschwemmter oder in trockener Form, veranlassen. Ebenso kann man auch den abbindungsfähigen Materialien bzw. den sie enthaltenden Gemischen die entsprechenden Reagenzien- einverleiben und so, die Bildung der angestrebten Verbindungen bei Zugabe des präparierten Zuschlagsmaterials veranlassen.So you can z. B. the aggregate materials with solutions of catalysts supplying salts or compounds soak the mixture in a moist state or after drying the. settable materials or those containing them Mix in mixtures and then the formation of the suitable catalysts Connections, e.g. B. oxides, hydroxides or the like, by adding suitable compounds, z. B. sodium hydroxide, soda, lime, ammonia o. The like., Be it in dissolved or in bloated or in dry form. You can also use the bondable Materials or those containing them Mix the appropriate Reagents incorporated and so, the formation of the desired compounds when added arrange for the prepared aggregate material.
Man kann aber z. B. auch derart verfahren, daß man, nachdem die Zuschlagsmaterialien, mit den betreffenden Salzen oder- Verbindungen getränkt oder angefeuchtet sind, die Umsetzung bewerkstelligt, ehe .die Zuschlagsmaterialien mit den. abbindungsfähigen . Materialien oder den sie enthaltenden Ge-, mischen gemischt werden. Zu diesem Zwecke' verfährt man z. B. derart, daß man. Sand, Ziegelmehl, Holzmehl mit Lösungen o. dgl., z. B. von Eisenchlorid, Eisensulfat, Mangansulfat o. dgl. tränkt oder benetzt und sie sodann mit Lösungen von Ätzalkali; Soda, Calciumhydroxyd, Ammoniak o. dgl. in geeigneter Weise in Berührung bringt. Hierdurch werden die als Katalysatoren wirkenden Hydroxyde-oder Oxyde bzw. Superoxyde auf oder in dem Zuschlagsmaterial niedergeschlagen. Dieses so. vorbereitete Zuschlagsmaterial wird sodann den für die Herstellung von porösblasigen Massen geeigneten Stoffen einverleibt, wobei die Sauerstoff abgebenden Substanzen entweder schon anwesend sein oder nachträglich zugegeben werden können.But you can z. B. also proceed in such a way that, after the aggregate materials, are soaked or moistened with the relevant salts or compounds, the implementation accomplished before .the aggregate materials with the. bondable . Materials or the mixtures containing them are mixed. To this Purposes' one proceeds z. B. such that one. Sand, brick flour, wood flour with solutions or the like, e.g. B. of iron chloride, iron sulfate, manganese sulfate o. The like. Soaks or wets and then with solutions of caustic alkali; Soda, calcium hydroxide, ammonia or the like. brings into contact in a suitable manner. This acts as a catalyst acting hydroxides or oxides or super oxides on or in the aggregate material dejected. This so. prepared aggregate material is then used for the production of porous bubble masses incorporated suitable substances, the Oxygen-releasing substances either already be present or afterwards can be added.
In gegebenen Fällen, in denen die Salze bzw. Verbindungen selbst bereits katalytische Wirkung ausüben, ist es nicht erforderlich, vor- oder nach der Zumischung der Zuschlagsmaterialien zu den die Sauerstoff abgebenden Substanzen enthaltenden Mischungen durch Zufügung von geeigneten Reagenzien, wie z. B. Alkalien, eine Umsetzung herbeizuführen.In certain cases in which the salts or compounds themselves already exert a catalytic effect, it is not necessary before or after the admixture of the aggregate materials to those containing the oxygen-releasing substances Mixtures by adding suitable reagents, such as. B. alkalis, a reaction bring about.
Der Zusatz der in fertiger Form öder durch Umsetzung mit geeigneten Reagenzien die katalytisch wirkenden Substanzen liefernden Stoffe enthaltenden Zuschlagsmaterialien kann zü den abbindungsfähigen Stoffen, wie Zement, Gips o. dgl., vor, während oder nach der Anteigung mit geeigneten: Flüssigkeiten, wie Wasser, geschehen. Auch können die aktiven Sauerstoff enthaltenden Verbindungen vor, während oder nach der Zumischung der. Zuschlagsmaterialien. zu den abbindungsfähigen Stoffen diesen einverleibt werden.The addition of the finished form or by implementation with suitable Reagents, aggregate materials containing substances that provide catalytically active substances can zü the settable substances, such as cement, plaster o. The like., Before, during or after mixing with suitable: liquids such as water. Also can the active oxygen-containing compounds before, during or after admixing the. Aggregate materials. these are incorporated into the settable substances.
An. Stelle oder neben anorganischen Katalysatoren kann man ebenso wie bei dem Verfahren des Hauptpatents gegebenenfalls auch solche organischer Art im Sinne der Erfindung verwenden, indem man Lösungen derartiger Stoffe oder, jrn Falle, :daß sie flüssig sind, wie z. B. Blut, die Flüssigkeiten selbst von dem Zuschlagsmaterial aufsaugen läßt und das so vorbereitete Zuschlagsmaterial, gegebenenfalls nach vorherigem Trocknen, zur Anwendung bringt. Beispiele i. 5 g Mangansulfat werden in 5oo ccm :Wasser gelöst. Mit dieser Lösung werden 3,5t0 g Bimskies gründlich benetzt, worauf man den angefeuchteten Kies einem Trocknungsprozeß unterwerfen kann. Der so vorbereitete Kies wird sodann mit 3000 g Eisen-Portlandzement _ gründlich vermischt und mit 2,5 1 Wasser, das vorteilhaft Zoo ccm einer 0;5°/oigen Seifenlösung enthält, angerührt. Nach gründlicher Durchmischung gibt man langsam unter Rühren goo ccm Wasserstoffsuperoxydlösung 6ojoig hinzu. Um die Gas-'- entwicklung zu beschleunigen, kann man noch geringe Mengen einer verdünnten Natriumhydroxydlösung zusetzen.At. Instead of or in addition to inorganic catalysts, as in the process of the main patent, those of an organic nature can optionally also be used within the meaning of the invention by using solutions of such substances or, in the case of: that they are liquid, such as e.g. B. blood, which allows the liquids themselves to be absorbed by the aggregate material and brings the aggregate material prepared in this way, optionally after drying, to use. Examples i. 5 g of manganese sulphate are dissolved in 500 cc: water. 3.5t0 g of pumice gravel are thoroughly wetted with this solution, whereupon the moistened gravel can be subjected to a drying process. The gravel prepared in this way is then thoroughly mixed with 3000 g of iron Portland cement and mixed with 2.5 liters of water, which advantageously contains zoo cc of a 0.5% soap solution. After thorough mixing, goo ccm of hydrogen peroxide solution is slowly added with stirring. In order to accelerate the evolution of gas, small amounts of a dilute sodium hydroxide solution can also be added.
2.. 2-5o g trockenes Holzmehl werden mit einer Lösung von io g Eisensulfat in 20o ccm Wasser getränkt, worauf man mit einer Lösung von 300 ccm einer i@oJoigen Atznatronlösung gründlich. durchmischt, Das so vorbereitete Holzmehl wird sodann zu einer Anteigung von 2,2 kg Gips mit il/, 1 Wasser gegeben, worauf man 370 ccm einer 6°/oigen Wasserstoffsuperoxydlösung zugibt.2 .. 2-5o g dry wood flour are soaked with a solution of 10 g iron sulfate in 20 ° ccm water, whereupon one thoroughly with a solution of 300 ccm of a 10% caustic soda solution. The wood flour prepared in this way is then added to 2.2 kg of gypsum with 1/1 of water, whereupon 370 cc of a 6% hydrogen peroxide solution is added.
3. 2o g Mangansulfat werden in .2oo ccm Wasser gelöst und die Lösung in 700 g Ziegelmehl aufgenommen. Nach dem Trocknen wird das Gemisch in eine Lösung von, 25o ccm einer io/öigen Natriumhydroxyd enthaltenden Lösung eingetragen. Dieses so vorbereitete fertige . Zuschlagsmaterial wird sodann in eine Anteigung gegeben, welche aus 2,4 kg Gips, 2,6 i Wasser, in welchem io g Natriumperborat gelöst sind und welchem außerdem 30 ccm einer o,5o/oigen Seifenlösung zugesetzt worden sind.3. 20 g of manganese sulphate are dissolved in .2oo ccm of water and the solution is taken up in 700 g of brick dust. After drying, the mixture is introduced into a solution of 250 cc of a solution containing 10% sodium hydroxide. This so prepared finished. The aggregate material is then poured into a paste consisting of 2.4 kg of gypsum, 2.6 liters of water, in which 10 g of sodium perborate are dissolved, and to which, in addition, 30 cc of a 0.5% soap solution has been added.
Für die Herstellung von mit Blasen durchsetzten, Kunststeinen ist es an sich bekannt, die die Gasentwicklung bewirkenden Stoffe ebenso wie die Gas abgebenden Stoffe, bevor sie miteinander zur Reaktion gebracht werden, zuerst als Lösung oder in. anderer geeigneter Gestalt mit zuzusetzenden indifferenten Füllstoffen, wie Sägemehl o. dgl., zu vereinigen.It is used for the manufacture of bubble-infused, artificial stones it is known per se, the substances causing the evolution of gas as well as the gas emitting substances before they are reacted with one another, first as Solution or in another suitable form with indifferent fillers to be added, such as sawdust or the like. To unite.
