E. FALKNER-RUMPF in BASEL Verfahren zur Herstellung elektrisch leitender Körper. E. FALKNER-RUMPF in BASEL Process for the production of electrically conductive bodies.

Patentirt im Deutschen Reiche vom 2. August 1898 ab.Patented in the German Empire on August 2nd, 1898.

Das vorliegende Verfahren verfolgt den Zweck, das Brennen bezw. Ausglühen der unter Verwendung theerartiger 'Bindemittel, hergestellten elektrisch leitenden Körper zu erleichtern und abzukürzen, ohne dafs die betreffenden Körper durch die Zersetzung des Bindemittels blasige Auftreibungen oder Risse erhalten. Hierbei wird, um eine gute Vertheilung des Bindemittels zu erzielen, dieses vor seiner Vermengung mit dem den Körper bildenden pulverförmigen Stoff (z. B. Kohle) verdünnt, jedoch nicht wie bisher durch einen das Bindemittel auflösenden Stoff, sondern dadurch, dafs es mit über 25 Gewichtsprocenten Wasser in eine feine und dauerhafte Emulsion verwandelt wird.The present method has the purpose of burning BEZW. Annealing the under Use of tar-like 'binders to facilitate manufactured electrically conductive bodies and abbreviate without affecting the bodies concerned by the decomposition of the binding agent have blistered swellings or cracks. In order to ensure a good distribution of the To achieve binding agent, this before its mixing with the body forming powdery substance (e.g. coal) is diluted, but not as before by a binding agent dissolving substance, but rather because it contains more than 25 percent by weight of water in a fine and permanent emulsion is transformed.

Beim Brennen oder Ausglühen des Formkörpers wird infolge der feinen Vertheilung des mit Wasser versetzten Bindemittels in dem Körper das Wasser gleichmäfsig verdampfen und Poren bilden, durch welche die flüchtigen Theerbestandtheile leicht entweichen können. Da das Wasser mit dem Bindemittel nicht capillar zu einer einzigen Flüssigkeit zusammenfliefsen kann, hindert es von Anfang an jede Verstopfung der entstandenen Poren und erlaubt so ein -viel rascheres Steigern der Temperatur beim Brennen als bei bisherigen Methoden, da die entstehenden Gase ungehinderten Abzug finden.When firing or annealing the shaped body, as a result of the fine distribution of the binder mixed with water in the body evaporate the water evenly and form pores through which the volatile tar components can easily escape. Since the water and the binding agent do not flow together capillary into a single liquid it prevents any clogging of the resulting pores from the start and allows such a much faster increase in temperature during firing than with previous methods, because the resulting gases can be vented unhindered.

Diese Wirkung kommt nur dann richtig zur Geltung, wenn genügend grofse Mengen Wasser in der Emulsion des Bindemittels vorhanden sind, und wenn die Emulsion so innig und dauerhaft ist, dafs sie bei über 25 pCt. Wassergehalt selbst nach langem, ruhigem Stehen keine wässerige Schicht abscheidet.This effect is only really effective when there is sufficient quantity of water are present in the emulsion of the binder, and if the emulsion is so intimate and is permanent that at over 25 pCt. Water content, even after standing still for a long time, none separates an aqueous layer.

Zur Herstellung einer derartigen Emulsion ist das Zusetzen gewisser Substanzen nöthig, welche zu jeder der beiden Flüssigkeiten eine gewisse Affinität' besitzen. Solche Substanzen, welche je nach dem gewählten theerartigen Bindemittel sowohl für sich allein als auch passend unter sich und mit letzteren vermischt verwendet werden können, sind beispielsweise das Kreosot und andere Phenolkörper, sowie solche organischen Substanzen, welche mit Wasser eine gallertartige Beschaffenheit anzunehmen fähig sind, wie z. B. Gelatine.To produce such an emulsion it is necessary to add certain substances, which have a certain affinity for each of the two liquids. Such substances which, depending on the tar-like binder chosen, both on its own and can be used appropriately with each other and mixed with the latter are, for example the creosote and other phenolic bodies, as well as those organic substances which with Water are able to take on a gelatinous consistency, such as B. gelatin.

Von dem so zubereiteten Bindemittel wird dem pulverförmigen Stoff nur so viel zugesetzt, als gerade zu dessen Bindung erforderlich ist. Beides wird sodann tüchtig mit einander gemischt und aus der Mischung darauf der betreffende Körper geformt.Only so much of the binder prepared in this way is added to the powdery substance, than is just necessary for its binding. The two are then thoroughly mixed with one another and the body in question is formed thereon from the mixture.
