KLASSE 80: Thon- und Steinwaaren- Industrie.CLASS 80: Clay and stone ware industry.
Patentirt im Deutschen Reiche vom 26. Juli 1891 ab.Patented in the German Empire on July 26, 1891.
Das Wesentliche dieser Erfindung . besteht darin, eine solche Anrührung des fein gemahlenen, gesiebten und gebrannten Gypses mit Wasser vorzunehmen, dafs die Gypsmasse nach ihrer Erhärtung bläsenfrei ist. Es ist diese Erfindung von weittragender Bedeutung für Porcellan- und Thonwaaren-Fabrikanten, Bildhauer und Gypsgiefser, überhaupt für alle Industrielle, welche feine blasenfreie Gypsmodelle zur tadellosen Herstellung ihrer Erzeugnisse benöthigen.The essence of this invention. consists in mixing the finely ground, sifted and fired gypses with water to make the gypsum mass is free of bubbles after it has hardened. This invention is of paramount importance for porcelain and clay manufacturers, sculptors and plasterers, for everyone in general Industrial, which fine, bubble-free gypsum models for the flawless manufacture of your products need.
Das Bedürfnifs, blasenfreien Gyps zu erhalten, hat seit immer vorgelegen, und sind manche Versuche, um dieses Ziel zu erreichen, gemacht worden. So ist versucht worden, den Gyps dadurch blasenfrei zu erhalten, dafs man beim Brennen bis zu einem gewissen Wärmegrad vorgegangen ist, in der Meinung, durch das dadurch erfolgte Austreiben des Krystallisationswassers aus dem Gyps diesen nach dem Anrühren mit Wasser blasenfrei zu erhalten. Nachdem aber auch diese Versuche keinen blasenfreien Gyps lieferten und jetzt dem luftfreien Gyps selbst die Schuld der Blasenbildung nicht mehr zugeschrieben werden konnte, war es eine nothwendige Folgerung, anzunehmen, dafs das Wasser die Luftblasenbildung veranlafst, weil nichts anderes dem Gyps hinzugesetzt wird, und diese Annahme ist die richtige, denn nach dem Anrühren mit gewöhnlichem Flufs - oder Brunnenwasser nimmt der Gyps beim Uebergang von dem flüssigen in den festen Zustand, d. h. beim Erhärten , thatsächlich die Wasserluftblasen in sich auf.The need for vesicle-free gypsis has always existed and is some attempts have been made to achieve this goal. So it has been tried that To keep gypsis free of bubbles by burning them up to a certain degree of warmth proceeded, in the opinion, by expelling the crystallization water as a result from the gypsum to get this bubble-free after mixing with water. But after even these attempts did not deliver a bubble-free Gyps and now the air-free one Gyps himself could no longer be blamed for the blistering, it was a necessary inference that to assume that the water causes the formation of air bubbles, because nothing else does Gyps is added, and this assumption is correct, for after mixing with The Gypsus takes ordinary river or well water on the passage from it liquid to solid, d. H. when hardening, actually the water air bubbles in to.
Um eine derartige Luftaufnahme unmöglich zu machen, wird hier als das neue Verfahren zur Herstellung von blasenfreiem Gyps das Anrühren des Gypses mit solchem Wasser gekennzeichnet , welches überhaupt keine Luft enthält, also mit destillirtem, frisch gekochtem Wasser.In order to make such an aerial photograph impossible, the new procedure is called here for the production of bubble-free gypsum the mixing of gypses with such water is characterized which contains no air at all, that is, with distilled, freshly boiled Water.
Man rührt den Gyps mit dem »luftfreien« Wasser in einem Gefäfs an und entfernt die beim Umrühren an die Oberfläche etwa noch vereinzelt aufsteigenden Wasserbläschen, bringt die Masse dann, nachdem sie gehörig angerührt ist, in das als Form bestimmte Gefäfs, schüttelst sie je nach Bedarf mehr oder weniger stark, entfernt die etwa noch aufsteigenden Luftblasen und läfst den Brei schliefslich erhärten. Hierauf wird durch Umstülpen der Form die erhärtete Masse, also das Gypsmodell freigelegt, welches nun keine Luftblasen mehr aufweist.You stir the Gyps with the "air-free" water in a vessel and remove it when stirring, brings about occasionally still rising water bubbles to the surface the mass then, after it has been properly mixed, into the vessel determined as a form, shake them more or less vigorously as needed, removes the ones that are still rising Air bubbles and finally allow the pulp to harden. Then the Form the hardened mass, i.e. the gypsum model is exposed, which now no longer has air bubbles having.
