Description

Säurefeste Dichtungspaste Inder chemischen Industrie liegt oft die Aufgabe vor, Flansche, Gewinde u.:dgl. gegenüber der Einwirkung von angreifenden Säuren zu schützen. Auch im Akkumulatorenbau ist ein Schutz der Polklemmen und anderer Teile gegenüber den Säurenebeln von großer Bedeutung.Acid-proof sealing paste in the chemical industry is often the Task before, flanges, threads, etc. against the action of attackers To protect acids. There is also protection for the pole terminals and others in accumulator construction Parts of great importance to the acid mist.

Gegenstand der Erfindung ist nun eine säurefeste Paste, die sich für die obengenannten Zwecke als vielfach verwendbar erwiesen hat. Dabei wird die Paste aus einfachen, leicht beschaffbaren chemischen Stoffen aufgebaut, und die Kombination :der im folgenden angegebenen Zusätze bringt die überraschende Wirkung eines dauerhaften Korrosionsschutzes, verbunden mit einer guten Abdichtung.The invention now provides an acid-resistant paste that is suitable for has shown the above purposes to be useful in many ways. In doing so, the paste made up of simple, easily obtainable chemical substances, and the combination : the additives given below brings the surprising effect of a permanent Corrosion protection combined with a good seal.

Die säurefeste Paste wird auf Vaseline als Grundmasse aufgebaut. Es genügt völlig, technische Vaseline zu verwenden. Zur Erreichung hoher Säurebeständigkeit werden der Vaseline Natronwasserglas, Magnesium in Form von Pulver und geringe Mengen von Bleioxyd beigemischt. Unter der Einwirkung von Säuren bilden :diese Stoffe harte, schützende Schichten, die imstande sind, der Säure .den Zutritt zum Metall der Oberfläche zu verwehren.The acid-resistant paste is based on Vaseline as a base. It It is completely sufficient to use technical petroleum jelly. To achieve high acid resistance The Vaseline are soda water glass, magnesium in powder form and small amounts mixed in with lead oxide. Form under the action of acids: These substances form hard, protective layers that are able to prevent acid from reaching the metal of the surface to refuse.

In der chemischen Industrie findet diese Paste häufig zum Abdichten von Flanschen oder schadhaften Stellen bei Säure oder angesäuerte Flüssigkeiten führenden Leitungen Anwendung. Bei Neuinstallationen von Säure führenden Leitungen können Gewinde- oder Flanschedichtungen in Form von durchlochten Scheiben aus Papier, Filz usw., -die mit dieser Paste durchtränkt sind, verwendet werden.In the chemical industry, this paste is often used for sealing of flanges or damaged areas in the case of acid or acidified liquids leading lines application. For new installations of lines carrying acid thread or flange seals in the form of perforated discs made of paper, Felt, etc. impregnated with this paste can be used.

Derartig behandelte durchlochte Scheiben können auch bei allen elektrochemischen Apparaten und Gegenständen, die Säuren oder angesäuerte Flüssigkeilen enthalten und aus deren Gehäuse Bolzen, Verschraubungen oder Kontakte ragen, an denen Säuren oder angesäuerte Flüssigkeiten hochkriechen können, zum Abdichten Verwendung finden.Perforated panes treated in this way can also be used in all electrochemical Apparatus and objects that contain acids or acidified liquid wedges contain and bolts, screw connections or contacts on which acids protrude from the housing or acidified liquids can creep up, can be used for sealing.

Der Aufbau der Paste wird. ,durch folgendes Ausführungsbeispiel .dargelegt: Zu 6o Gewic'htsteilen technischer Vaseline werden etwa 30 Gewichtsteile Natronwasserglas, = bis 5 Gewichtsteile Magnesium-Pulver und schließlich als restliche Gewichtsteile Bleioxyd zugesetzt: Nach gründlichem Durchmischen ist die Paste sofort verwendbar, sie kann aber auch beliebig lange ohne schädlichen Einfluß auf ihre Wirksamkeit aufbewahrt werden. Gegenüber der Anwendung von reiner Vaseline hat diese Paste bedeutende Vorteile: Der Vaselineanteil gibt die zum Auftragen günstige Konsistenz, Wasserglas und Magnesium bewirken eine Neutralisation der Säure und einen Schutz gegen Oxydation. Diese Wirkung wird durch den Bleioxydzusatz noch erhöht.The build up of the paste will. , .dargelegt by the following embodiment: To 6o Gewic'htsteilen Vaseline be about 30 parts by weight of sodium silicate, = added to 5 parts by weight of magnesium powder, and finally as residual parts by weight of lead oxide: After thorough mixing, the paste is ready for immediate use, but they can also be as long as desired be stored without detrimental effect on their effectiveness. Compared to the use of pure vaseline, this paste has significant advantages: The vaseline content gives it a good consistency for application, water glass and magnesium neutralize the acid and protect against oxidation. This effect is increased by the addition of lead oxide.
