Abstract

According to the application, a glazed, expanded perlite grain is used as pore-forming aggregate. In the production of tiles, this achieves increased stability and no swelling of the raw tile body. In addition, no waste gas pollution occurs on firing the tiles.

Description

Die Erfindung betrifft die Verwendung von glasiertem, geblähtem Perlitkorn als porenbildenden Zusatzstoff bei der Ziegelherstellung.The invention relates to the use of glazed, bloated Pearlite grain as pore-forming additive in brick manufacture.

Ein derartiges Perlitkorn ist aus der DE-OS 32 39 504 bekannt.Such a pearlite grain is from DE-OS 32 39 504 known.

Aus fertigungstechnischen Gründen sowie zur Verbesserung der Wärmedämmung, wird zur Ziegelherstellung dem Ton, Lehm oder der tonigen Masse porenbildende Zusatz­ stoffe beigegeben.For manufacturing reasons as well For improvement thermal insulation, clay is used for brick production, Clay or clayey pore-forming additive added substances.

Bekannt sind die ausbrennbaren Zusatzstoffe, wie z. B. Sägespäne, Holzmehl, Papierschlamm, Hopfentreber u. a. sowie die Zugabe von Polystyrol (Styropor). Der Nachteil aller dieser Zuschlagstoffe ist, daß diese nicht wie das Grundmaterial des Ziegels, auf mine­ ralischen Stoffen beruhen, daß die Zuschlagstoffe beim nassen Misch- und Formvorgang mehr oder weniger stark quellen, die ausbrennenden Zuschlagstoffe eine starke Abgasbildung verursachen, daß der Quellvorgang sowie die Abgasbe­ lastung die Zugabe der Zuschlagstoffe begrenzt und damit die Porosierung.The burn-out additives, such as. B. Sawdust, wood flour, paper sludge, hop scrapers and the like. a. and the addition of polystyrene (styrofoam). The disadvantage of all of these additives is that this doesn't like the basic material of the brick, on mine ralische substances are based on the fact that the aggregates and the molding process swell more or less burned out aggregates a strong exhaust gas formation cause the swelling process as well as the exhaust gas load limits the addition of additives and thus the porosity.

Aufgeblähtes, unglasiertes Perlitkorn als mineralischen Zuschlagstoff zur Ziegelherstellung zu verwenden ist nicht möglich. Das unglasierte, jedoch aufgeblähte Perlit­ korn verliert bereits beim nassen Mischvorgang die Sta­ bilität, bzw. seine porenbildenden Eigenschaften.Inflated, unglazed pearlite grain as mineral Additive to be used for brick production not possible. The unglazed but blown pearlite Grain loses its staple during the wet mixing process bility, or its pore-forming properties.

Der Erfindung liegt die Aufgabe zugrunde, einen porenbildenden Zusatzstoff für die Ziegelher­ stellung zu finden, der mineralisch ist, der die Zugabe einer größeren Menge zuläßt und die Abgas­ belastung verringert.The invention has for its object a pore-forming additive for brick makers to find a position that is mineral, that is Adding a larger amount allows and the exhaust gas load reduced.

Die Aufgabe wird erfindungsmäßig dadurch gelöst, daß als Zuschlagstoff glasierter, geblähter Perlit verwendet wird.The object is achieved in that as Glazed, bloated aggregate Perlite is used.

Durch die Glasierung des aufgeblähten Perlitkornes entsteht eine Kornstabilität und Wasserabweisung. Die Kornstabilität ermöglicht das Pressen stark gelochter Ziegel, die Wasserabweisung verhindert das Aufquellen der Lochstege trotz großer Zugabe von porosierenden Zuschlagstoffen.By glazing the inflated pearlite grain there is grain stability and water repellency. The grain stability enables pressing strongly perforated brick that prevents water repellency the swelling of the perforated webs despite a large encore of porous aggregates.

Die Ziegelherstellung erfolgt bei ca. 900°C.Brick production takes place at approx. 900 ° C.

Die Perlitkörner werden bei ca. 1000°C aufgebläht und glasiert. Der Zuschlagstoff ist somit bei der Herstellung einer höheren Temperatur ausgesetzt ge­ wesen als dann bei der Ziegelherstellung, was eine minimale Abgasbelastung zur Folge hat.The pearlite grains are inflated at approx. 1000 ° C and glazed. The aggregate is therefore at Manufacturing exposed to a higher temperature than then in brick making, what a minimal exhaust emissions.
