Description
Verfahren zur Herstellung von kalt glasierten Zementplatten u. dgl. Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Wand- und Fußbodenfliesen oder -platten, Ornamenten, Gefäßen u. dgl. aus Kalk, Zement o.. dgl.Process for the production of cold glazed cement boards and the like. The invention relates to a method for producing wall and floor tiles or plates, ornaments, vessels and the like made of lime, cement or the like.
Es ist allgemein bekannt, daß man eine Kalkmörtel- oder Zementmörtelmasse dadurch zum schnellen Abbinden bringt, daß man sie unter Dampfdruck und die Einwirkung der damit verbundenen großen Hitze bringt und so den Abbindeprozeß fördert.It is well known that one can use a lime mortar or cement mortar mass by bringing it to the rapid setting that one brings it under steam pressure and the action the associated great heat and thus promotes the setting process.
Auch hat man die Platten u. dgl. vor der Hochdruckschnellhärtung in feuchter Umgebung ohne Druck gelagert, und zwar bei Anwendung von Stoffen durchgehend gleicher Beschaffenheit.The plates and the like are also in stored in a humid environment without pressure, when using substances continuously same quality.
Verwendet man jedoch verschiedene Mischungen für die sogenannte Kaltglasur und die Hauptmasse, so kommen beim Abbinden dieser verschiedenen Mischungen unter Druck und großer Hitze verschiedene Schwind- bzw. Ausdehnungskoeffizienten zur Geltung, die beim schnellen Abbinden, wie es unter Druck vor sich geht, eine Zerstörung der Glasur hervorrufen, so daß die Glasur Risse erhält und von den unteren Scherben abblättert.However, if you use different mixtures for the so-called cold glaze and the main mass, so come under when setting these various mixtures Different shrinkage and expansion coefficients are shown to advantage under pressure and extreme heat, the rapid setting, as it happens under pressure, a destruction of the Create glaze so that the glaze gets cracked and from the lower shards flakes off.
Der Erfindung liegt die Erkenntnis zugrunde, daß die Glasur während des Prozesses gegen Zugluft und äußere atmosphärische Einflüsse irgendwelcher Art geschützt werden muß, da durch diese eine Zerstörung der Glasur eintritt, indem die äußere Dichtigkeit, d. h. die Anhäufung feinster kolloidaler Massen in der Oberfläche, welche die Glasur erzeugen, verlorengeht. Es tritt eine Umlagerung dieser feinsten, äußersten Stoffe ein, so daß der Glanz zerstört wird.The invention is based on the knowledge that the glaze during the process against drafts and external atmospheric influences of any kind must be protected, as this will destroy the glaze by the external tightness, d. H. the accumulation of the finest colloidal masses on the surface, which produce the glaze is lost. A rearrangement of these finest, extreme substances, so that the shine is destroyed.
Um diese Nachteile zu verhindern, soll gemäß der Erfindung die kalt glasierte Ware die gesamte Vor- und Nachbehandlung im Erhärtungsraume durchmachen.In order to avoid these disadvantages, according to the invention, the cold Glazed goods go through the entire pre- and post-treatment in the hardening room.
Ein. Beispiel für den Arbeitsvorgang ist folgendes Es werden Zementplatten gestampft und unter Druckluft mit der äußeren Glasur versehen, so daß ein äußerer Glanz der Platte erzielt wird. Die Platte wird sodann in den Erhärtungsraum gebracht, in welchem sie etwa 6 bis 1a Stunden abbindet bei Temperaturen von etwa 2o bis q.0° C, ohne Druck, bei einem Feuchtigkeitsgehalt der umgebenden Atmosphäre von etwa 95 bis 99 Prozent. Dann wird die Platte in dem gleichen Raum unter einen Dampfdruck von bis zu 9 Atm. gesetzt und der damit verbundenen hohen Temperatur ausgesetzt. Diesem Druck und dieser Temperatur wird die Platte dann 6 bis 8 Stunden ausgesetzt. Dadurch, daß die ,Platte beide Prozesse in dem gleichen Erhärtungsraum durchmacht, wird sie verschiedenartigen ,äußeren atmosphärischen Einflüssen entzogen.A. Example of the work process is the following There are cement panels tamped and provided with the outer glaze under compressed air, so that an outer Shine of the plate is achieved. The plate is then brought into the hardening room, in which it sets for about 6 to 1a hours at temperatures of about 20 to q.0 ° C, without pressure, with a moisture content of the surrounding atmosphere of about 95 to 99 percent. Then the plate is in the same space under a vapor pressure of up to 9 atm. set and exposed to the associated high temperature. The plate is then exposed to this pressure and temperature for 6 to 8 hours. Because the plate goes through both processes in the same hardening room, it is withdrawn from various external atmospheric influences.
Auf diese Weise wird erreicht, daß die inneren Kohäsionskräfte der Platte größer sind als die verschiedenen Schwind- bzw. Ausdehnungskräfte und daß eine einheitliche Struktur der Platte gewahrt bleibt.In this way it is achieved that the internal cohesive forces of the Plate are greater than the various shrinkage or expansion forces and that a uniform structure of the plate is preserved.
