Description
Verfahren zur Wiederverwertung der niagnesiazementhaltigen Rückstände und Bruchstücke der Steinholz- und Kunstmarmor-Industrie Zusatz zum Patent 514710 Die Erfindung betrifft eine weitere Ausbildung des in dem Patent 5 14 7 1 o beschriebenen Verfahrens zur Wiederverwertung der magnesiahaltigen Rückstände und Bruchstücke aus der Steinholz- und Kunstmarmor-Industrie.A process for recycling of niagnesiazementhaltigen residues and fragments of Steinholz- and artificial marble industry addition to Patent 514710 The invention relates to a further development of the in Patent 5 14 7 1 o-described method for recycling the magnesian residues and debris from the Steinholz- and Kunstmarmor- Industry.
Gemäß dem Hauptpatent werden die magnesiahaltigen Rückstände und Bruchstücke zerkleinert und mehrere Male durch Wässern von allen leicht löslichen Bestandteilen befreit und dann als Zuschlag für Portlandzementmörtel verwendet.According to the main patent, the magnesia-containing residues and fragments crushed and several times by soaking all easily soluble ingredients exempted and then used as an aggregate for portland cement mortar.
Das neue Verfahren besteht nun darin, daß die durch Wässern gereinigten Abfälle einer weiteren Behandlung mit verdünnter Salzsäure unterworfen werden.The new method now consists in that the cleaned by soaking Waste is subjected to further treatment with dilute hydrochloric acid.
Durch das Behandeln der gewässerten Bruchstücke mit verdünnter Salzsäure werden die an der Oberfläche der Kunststeinmasse befindlich-en wasserschwerlöslichen Magnesiasalze gelöst, wodurch die Bruchstücke eine rauhe schwammige Oberfläche erhalten und infolgedessen sich innig mit Mörtel aller Art verbinden.By treating the soaked fragments with dilute hydrochloric acid are those on the surface of the artificial stone mass that are sparingly soluble in water Magnesia salts dissolved, giving the fragments a rough, spongy surface and as a result combine intimately with mortar of all kinds.
Die bei der Säurebehandlung aus den gefärbten Abfällen abfallenden Farbstoffe können wieder zum Färben von Kunststeinmassein nutzbar gemacht werden.Those falling off from the colored waste during the acid treatment Dyes can be used again for coloring artificial stone masses.
