Verfahren zur Herstellung künstlichen Marmors und künstlicher Steine.
Vorliegende Erfindung betrifft ein Verfahren zur Herstellung künstlichen Marmors und künstlicher Steine durch Einwirkung von Kohlensäuregas auf Kalk.
Es ist allerdings bereits bekannt, geformte Kalkblöcke in luftleer gemachten Behältern oder Kammern der Einwirkung von Kohlensäuregas auszusetzen, um dadurch eine Härtung der Blöcke zu erzielen. Hiebei wurde aber das Kohlensäuregas in den die Blöcke aufnehmenden Behälter stets unter Druck hineingetrieben und dieser Druck auch während der fortschreitenden Absorption der Kohlensäure durch den Kalk aufrechterhalten, bezw. von Zeit zu Zeit erhöht.

Process for the production of artificial marble and stones.
The present invention relates to a method for producing artificial marble and stones by the action of carbonic acid gas on lime.
It is, however, already known to expose shaped lime blocks in evacuated containers or chambers to the action of carbonic acid gas in order to thereby achieve hardening of the blocks. In doing so, however, the carbonic acid gas was always driven into the container holding the blocks under pressure and this pressure was maintained or maintained even during the progressive absorption of the carbonic acid by the lime. increased from time to time.
According to the present invention, the carbonic acid gas is not used under pressure; rather, the blocks or plates of lime to be treated are in the
EMI1.1
Pressures of 70 mm of mercury has been produced accordingly by means of a pump, the carbonic acid gas is only introduced until a significantly higher, but still substantially below atmospheric pressure z. B. one of about 630 mm of mercury, inside dos container came about.
As the blocks progressively harden, the gas is removed from the latter.
EMI1.2
the pressure caused by the initially supplied gas is reduced, gas is allowed to flow in again and again in order to maintain the pressure reached in the container by the original gas supply, but still subatmospheric pressure, as far as possible.
As soon as the vacuum present in the container no longer shows an increase, the action of the carbonic acid on the blocks or plates is over and the same can be removed.
