KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegendes Verfahren betrifft die Herstellung von Ziegeln, Steinen U. s. w. aus ungebranntem, möglichst sandfreiem Thon und Kalk unter Dampfdruck.The present process relates to the production of bricks, stones, etc. from unfired, If possible, sand-free clay and lime under steam pressure.
Kunststeine aus Sand oder sandartigen, also nicht plastischen Materialien und Kalk mit oder ohne Zusatz von Thon unter Dampfdruck oder dergl. herzustellen, ist bekannt. Bei allen diesen Verfahren findet bei der Erhärtung der Masse die Bildung von Calciumhydrosilicat oder kieselsaurem Kalk statt, wobei die Sandkörner der Masse zusammengekittet werden. Ferner ist es bekannt, ein Gemenge von Thon und Kalk zu brennen, um Kunststeine herzustellen. Artificial stones made of sand or sand-like, i.e. non-plastic materials and lime with or Manufacture without the addition of clay under steam pressure or the like. Is known. At all In this process, calcium hydrosilicate is formed when the mass hardens or silicate lime instead, whereby the grains of sand of the mass are cemented together. It is also known to burn a mixture of clay and lime to produce artificial stones.
Von diesen bekannten Verfahren unterscheidet sich das vorliegende also dadurch, dafs Kunstsleine aus möglichst sandfreien, ungebrannten Thonen und Kalk unter Dampfdruck gehärtet werden. Die Erhärtung der Masse wird dabei im Wesentlichen durch die Bildung von KaIkaluminat neben der von Kalksilicat bewirkt. Um diesen Zweck zu erreichen, kann der Kalk je nach der Eigenschaft des zur Verfügung stehenden Thones, d. h. je nach seiner Plasticität, als Kalkbrei oder Kalkmilch oder als gemahlener gebrannter Kalk ohne Wasserzusatz in geeignetem Verhältnifs, etwa 10 bis 20 pCt. Kalk in Form von gebranntem Kalk, dem Thon beigemengt werden.The present one differs from these known methods in that it has artificial rope Hardened from sand-free, unfired clays and lime under steam pressure will. The hardening of the mass is essentially due to the formation of calcium aluminate in addition to that of lime silicate. To achieve this end, the lime can depending on the properties of the available clay, d. H. depending on its plasticity, as lime paste or milk of lime or as ground quick lime without added water in suitable proportions, about 10 to 20 pct. Lime in the form of quick lime, the Can be added to clay.
Die Ausführung des Verfahrens geschieht zweckmäfsig in folgender Weise:The procedure is expediently carried out in the following way:
Der möglichst sandfreie, ungebrannte, feuchte Thon wird je nach seiner Beschaffenheit mit etwa 10 bis 20 pCt. feingemahlenem, gebranntem Kalk versetzt und innig mit letzterem gemischt. Die Mischung erhitzt sich und wird bei fortgesetztem Durcheinandermengen krümelig und trocken. In diesem Zustande kann die Masse gelagert werden, wobei die völlige Ablöschung des Kalkes in dem Thon stattfindet. Vor der Pressung oder dem Formen kann nach Bedarf etwas Wasser zugegeben werden, wenn die Mischung nicht genügend prefsfeucht ist.The as far as possible sand-free, unfired, moist clay is depending on its nature with about 10 to 20 pCt. finely ground, burnt Lime added and mixed intimately with the latter. The mixture heats up and becomes crumbly and with continued mixing dry. In this condition the mass can be stored, with complete extinction of the lime takes place in the clay. Before pressing or molding, it can be used as required a little water can be added if the mixture is not moist enough.
Von der Presse gelangen die geformten Stücke in bekannter Weise auf geeigneten Wagen direct in die Hartekessel, in welchen sie 3 bis 10 Stunden einem Dampfdruck von 10 bis 25 Atmosphären ausgesetzt bleiben, worauf sie völlig erhärtet und gebrauchsfähig sind.From the press, the shaped pieces arrive in a known manner in a suitable manner Carriages directly into the hard boiler, in which they have a steam pressure of 3 to 10 hours Are exposed to 10 to 25 atmospheres, after which they completely hardened and usable are.
Bei sehr zähen Thonen wird das grubenfeuchte Thonmaterial mit Kalkmilch bis zur Erzielung einer gleichfalls homogenen Masse innig verarbeitet, bei welcher man vor dem Formen durch Zugabe von getrocknetem Thon die etwa erforderliche Steifheit reguliren kann.In the case of very tough clays, the pit-moist clay material is mixed with milk of lime up to Achieving an equally homogeneous mass intimately processed, in which one before the Shaping can regulate the necessary rigidity by adding dried clay.
Die nach vorliegendem Verfahren hergestellten Erzeugnisse zeichnen sich durch ihre bessere Luft- und Wasserbeständigkeit aus, da sie denaus hydraulischen, durch Glühen erhaltenen Kalkhydroaluminaten hergestellten Erzeugnissen gleichen, ferner dadurch, dafs sie wie gesintert erscheinen und ein viel feineres Gefüge besitzen, während die bekannten Kunstsandsteine oder Kalksandsteine mehr oder minder grobkörnig sind, da hierbei in der Hauptsache :: Sande oder sandartige, also im feuchten Zu-The products manufactured according to the present process are characterized by their better quality Air and water resistance, as they are those obtained from hydraulic annealing Lime hydroaluminates resemble products made, furthermore in that they look like sintered appear and have a much finer structure than the well-known artificial sandstones or sand-lime bricks are more or less coarse-grained, as this is mainly the case :: Sand or sand-like, i.e. in a moist environment
