Verfahren zum Reinigen von Glas.
Patentiert im Deutschen Reiche vom 9. August 1912 ab.Process for cleaning glass.
Patented in the German Empire on August 9, 1912.
Die Erfindung besteht in einem neuen Verfahren, zum Reinigen von verschmutztem Glas. Danach wird das Glas mit einer Mischung von ungefähr 4 Gewichtsteilen Flußsäure (etwa 32prozentig), 1 Gewichtsteil schwefliger Säure (etwa 4,4 prozentig), 1 Gewichtsteil Antimonchloridlösung (etwa 32,5 prozentig), 1 Gewichtsteü Zinkchloridlösung (etwa 32,2prozentig) und 3 Gewichtsteilen Salzsäure (etwa 32,5 prozentig) bestrichen und nach einigen Minuten mit Wasser abgespült. Sollte der Schmutz noch nicht ganz entfernt sein, so wird das Verfahren ein zweites Mal wiederholt.The invention consists in a new method for cleaning dirty glass. The glass is then treated with a mixture of approximately 4 parts by weight of hydrofluoric acid (approx 32 percent), 1 part by weight of sulphurous acid (about 4.4 percent), 1 part by weight of antimony chloride solution (about 32.5 percent), 1 part by weight of zinc chloride solution (about 32.2 percent) and 3 parts by weight of hydrochloric acid (about 32.5 percent) and after a few minutes with Rinsed off with water. If the dirt has not yet been completely removed, the procedure will be repeated a second time.
Die Verwendung von Säuren, wie Schwefeloder Salzsäure, und von sauren Salzen als Glasreinigungsmittel ist zwar bereits bekannt. Mit diesen bekannten Mitteln ist aber, auch bei gemeinsamer Anwendung, die Entfernung stark haftenden Schmutzes durch bloßes Nachspülen mit Wasser ohne Nachreiben nicht zu erreichen. Anscheinend wird die eigenartige Wirkung des Gemisches durch die Anwesenheit der Flußsäure bedingt.The use of acids, such as sulfuric or hydrochloric acid, and of acidic salts as Glass cleaning agents are already known. But with these known means, too when used together, the removal of stubborn dirt by simple rinsing not to be achieved with water without rubbing. Apparently the peculiar one Effect of the mixture due to the presence of hydrofluoric acid.
Die angegebenen Mengenverhältnisse können in gewissen Grenzen abgeändert werden.The specified proportions can be changed within certain limits.
Durch das beschriebene Verfahren läßt sich sogar eingebrannter Ruß von anscheinend vollständig entwertetem Glas entfernen, so daß dasselbe wieder vollständig kristallhell wird. Trotz dieser kräftigen Wirkung der Mischung auf die Verunreinigungen werden weder das Glas selbst noch seine metallenen Einfassungen angegriffen.The method described even removes what appears to be burnt-in soot Remove completely devalued glass so that it becomes completely crystal clear again. Despite this powerful effect of the mixture on the contaminants, neither will Glass itself still attacked its metal surrounds.
Das Verfahren eignet sich insbesondere zum Reinigen der Verglasungen industrieller Betriebe, Bahnhöfe u. dgl.The process is particularly suitable for cleaning the glazing of industrial plants, Railway stations and the like
