Description

Verfahren zur Herstellung von Kunststein aus Magnesia und Füllstoffen. Es wurde eine wichtige Anwendung der mit der Aufnahme von Kohlensäure und Wasser durch Magnesia enthaltende Massen verbundenen Volumenvermehrung darin gefunden, daß der mit ihr verbundene Druck zur Raumerfüllung von porösen Formen ausgenutzt wird.Process for the production of artificial stone from magnesia and fillers. It became an important application of the ingestion of carbonic acid and water increase in volume associated with masses containing magnesia found therein, that the pressure associated with it is used to fill the space of porous forms will.

Hierbei kommt die Volumenvermehrung infolge der Reaktion zwischen Magnesia, Kohlensäure und Wasser zu zweckmäßiger Ausnutzung, indem durch sie in der geschlossenen Form ein gewisser Druck bewirkt wird, welcher die Ausfüllung der Form mit der zu festen Gebilden erstarrenden Masse vervollständigt, ohne daß dabei die Hohlräume der Füllkörper zusammengepreßt werden.Here, the increase in volume as a result of the reaction comes between Magnesia, carbonic acid, and water to be exploited by putting through them in the closed form causes a certain pressure, which the filling of the Form completed with the solidified mass, without that the cavities of the packing are compressed.

Beispiele für die Anwendung des Verfahrens.Examples of the application of the procedure.

z. Es werden 6o Teile gebrannter Magnesit mit 4.o Teilen Sägemehl gemischt; die trockene Mischung wird in poröse Formen aus widerstandsfähigem Stoff lose eingefüllt, z. B. in solche, welche aus unglasiertem gebrannten Ton oder aus emailliertem Eisenblech, das siebartig durchlöchert ist, oder aus verzinntem oder verzinktem Drahtnetz oder anderem, Feuchtigkeit und Kohlensäure widerstehendem Stoff hergestellt sind.z. There are 6o parts of burnt magnesite with 4o parts of sawdust mixed; the dry mix is made into porous molds made of resilient fabric filled in loosely, e.g. B. in those made of unglazed fired clay or from enamelled sheet iron, perforated like a sieve, or made of tinned or galvanized wire mesh or other material resistant to moisture and carbon dioxide are made.

Die gefüllten Formen werden in einer Kammer übereinandergeschichtet, in welche feuchte kohlensäurehaltige Gase, z. B. feuchte Rauchgase, eingelassen werden.The filled forms are stacked in a chamber, in which moist carbonated gases, e.g. B. moist flue gases, let in will.

2. Es werden 8o Teile gebrannter Magnesit mit 2o Teilen Torfmehl gemischt, dann wird ebenso verfahren wie vorher.2. 8o parts burnt magnesite are mixed with 2o parts peat meal, then the same procedure is followed as before.

3. Es werden go Teile gebrannter Magnesit mit =o Teilen Korkmehl gemischt, dann wird ebenso verfahren wie vorher.3. 50 parts of burnt magnesite are mixed with = 0 parts of cork flour, then the same procedure is followed as before.

4.. Es werden 7o Teile gebrannter Magnesit mit 3o Teilen Kieselgur gemischt, dann wird ebenso verfahren wie vorher.4 .. There are 70 parts of burnt magnesite with 30 parts of diatomaceous earth mixed, then the same procedure is followed as before.

5. Es werden q.o Teile gebrannter Magnesit mit 6o Teilen Sand gemischt, dann wird ebenso verfahren wie vorher.5. q.o parts of burnt magnesite are mixed with 60 parts of sand, then the same procedure is followed as before.

Sinngemäß können noch mit zahllosen anderen Stoffen organischer oder anorganischer Herkunft solche einfachen oder auch aus mehr als zwei Bestandteilen zusammengesetzte Mischungen mit gebranntem Magnesit oder Magnesiumoxyd bzw. Magnesiumhydrat hergestellt und der Behandlung in geschlossenen porösen Formen unterworfen werden, wobei je nach dem spezifischen Gewicht der übrigen Mischungsbestandteile höhere oder geringere Zusätze von Magnesia erforderlich sind.Analogously, you can use countless other substances, organic or of inorganic origin, those simple or composed of more than two components composite mixtures with burnt magnesite or magnesium oxide or magnesium hydrate manufactured and subjected to treatment in closed porous molds, depending on the specific weight of the other components of the mixture, higher or minor additions of magnesia are required.
