Description

Spritzbare Masse zur Herstellung von Schutzanstrichen in unterirdischen Grubenbetrieben Das Hauptpatent betrifft eine spritzbare Masse für ein Verfahren zur Regelung der Luftfeuchtigkeit und Niederschlagen von Staub, insbesondere Kohlenstaub, in unterirdischen Grubenbetrieben. Nach dem Hauptpatent sollen die Strecken oder Teile derselben am Stoß und an der Firste mit einem zusammenhängenden Überzug einer Masse versehen werden, die einen oberflächenaktiven Stoff, ein Bindemittel und Salzsole enthält.Sprayable compound for the production of protective coatings in underground Mine operations The main patent relates to an injectable mass for a process to regulate the humidity and the precipitation of dust, especially coal dust, in underground mining operations. According to the main patent, the routes or Parts of the same at the joint and at the roof with a coherent covering of a Mass are provided which contain a surfactant, a binder and brine contains.

Es hat sich bei weiteren Untersuchungen ergeben, daß die nach dem Patent anzuwendende Spritzmasse vorteilhaft noch einen Zusatz von Wasserglas, Ammoniumsulfat und Rohglycerin enthält. Durch den Zusatz von Kupfervitriol wird die Reaktionsfähigkeit der Masse gegenüber Metallkörpern erheblich vermindert, wodurch der eiserne Grubenausbau gegen die Gefahr der Verrostung geschützt wird.It has been shown in further investigations that the after Patent to be applied injection molding compound advantageous also an addition of water glass, ammonium sulfate and contains raw glycerin. The addition of vitriol increases the reactivity the mass compared to metal bodies significantly reduced, which makes the iron mine support is protected against the risk of rusting.

Der Zusatz von Ammoniumsulfat oder einer anderen bei Erwärmung stickstoffabspaltenden Substanz erhöht die Schutzwirkung der AnstrichmassegegenBrand. SieerzeugtauchkühlendeDämpfe nach einer etwaigen Kohlenstaubexplosion, die die Staubflamme schnell zum Erlöschen bringen.The addition of ammonium sulfate or another nitrogen-releasing substance when heated Substance increases the protective effect of the paint against fire. It generates immersion cooling vapors after a possible coal dust explosion, which quickly extinguishes the dust flame bring.

Schließlich wird durch den Zusatz von Rohglycerin oder einem ähnlichen wasseraufnehmenden Stoff die Blasse in vorteilhafter Weise feucht gehalten, was für die Regelung der Luftfeuchtigkeit von großem Vorteil ist.Finally, by adding raw glycerin or something similar water-absorbing material kept the pale moist in an advantageous manner, What is of great advantage for regulating the air humidity.
