Description

Imprägnierungsmittel mit hoher Verkokungszahl für Bogenlichtelektroden. Die unter Verwendung kohlenstoffhaltiger Bindemittel hergestellten Bogenlichtelektroden sind bekanntlich nach dem Brennen sehr porös; wodurch nicht nur der Abbrand, sonrlern - besonders bei homogenen Effektkohlen, die die Leuchtsalze fein verteilt über den ganzen Querschnitt enthalten - auch die Ruhe des Lichtbogens und dessen Leuchtkraft ungünstig beeinflußt wird.Impregnation agent with a high coking number for arc light electrodes. The arc light electrodes made using carbonaceous binders are known to be very porous after firing; thereby not only the burn-up, sonrlern - especially with homogeneous effect carbons, which the luminescent salts are finely distributed over the contain the entire cross-section - also the rest of the arc and its luminosity is adversely affected.

Die Porosität beträgt bei solchen Kohlen in @-olutnenprozenten ausgedrückt etwa 1o bis 2o Prozent. Um diesen Nachteil zu beseitigen, ist e: üblich, die Elektroden nach dem Brennen noch mit Teer oder einem anderen kohlenstoffhaltigen Füllmittel zu imprägnieren sowie zu diesem Zwecke die Elektroden zunächst zu entlüften und dann auf das Imprägniermittel einen Drückt auszuüben, um es möglichst tief in die Poren der Elektroden hineinzupressen.The porosity of such coals is expressed in @ -olute percent about 1o to 2o percent. To overcome this disadvantage, it is common to use the electrodes after firing with tar or another carbonaceous filler to impregnate and, for this purpose, first of all to deaerate the electrodes and then exert pressure on the impregnating agent to get it as deep as possible into the Pressing in the pores of the electrodes.

Von wesentlichem Vorteile ist es, zur Imprägnierung der Bogenlichtelektroden als Imprägnierungsmittel kohlenstoffhaltige Materialien mit sehr hoher Y-erkokungszahl anzuwenden. Ein solcher Stoff ist beispielsweise Pech, das bis zu 5o Prozent Teerkoks ergibt. Die Erfindung besteht nun darin, daß dem als Imprägnierungsmittel verwendeten-und zu diesem Zwecke bereits bekannten Pech außerdem noch kolloidaler Kohlenstoff als Füllmaterial zugesetzt wird. Dieses neue Imprägnierungsmittel liefert noch mehr Koks bzw. Kohlenrückstand und dringt außerdem besser in die Poren ein, als Pech allein. Durch Verwendung dieses Imprägnierungsmittels lassen sich Bogenlichtelektroden herstellen, deren Brenndauer etwa das Doppelte der mit Teer imprägnierten beträgt und die einen besonders ruhigen Lichtbogen sowie eine sehr hohe Lichtausbeute ergeben.It is of considerable advantage to impregnate the arc light electrodes as an impregnating agent, carbonaceous materials with a very high Y-carbon number apply. Such a substance is, for example, pitch, which contains up to 5o percent tar coke results. The invention consists in that the used as an impregnating agent and pitch, which is already known for this purpose, is also known as colloidal carbon Filler material is added. This new waterproofing agent delivers even more Coke or coal residue and also penetrates the pores better than pitch alone. By using this impregnation agent, arc light electrodes can be created Manufacture whose burn time is about twice that impregnated with tar and which result in a particularly quiet arc and a very high light yield.
