Description

Verfahren zum Herstellen kohlenstoffhaltiger Erzeugnisse Ein einfaches und wenig kostspieliges Verfahren zur Erzeugung eines hochvoluminösen kohlenstoffhaltigen Granulates besteht darin, Ruß beliebiger Herkunft mit einer Lösung der Aufschwemmung eines organischen Stoffes zu versetzen. Als besonders zweckmäßig hat es seich erwiesen, Teer, Pech, Bitumen, Erdölrückstände oder Kunstharze, die mit Benzin versetzt sind, zu diesem Zweck zu verwenden, obwohl auch andere organische Stoffe geeignet sein können. Das Ge- misch wird in bekannter Weise granuliert. Anschließend wird dieses Granulat ohne Luftzutritt erhitzt.Process for producing carbon-containing products A simple and inexpensive process for producing high-volume carbon-containing granules consists in adding a solution of the suspension of an organic substance to carbon black of any origin. It has been found to be particularly expedient to use tar, pitch, bitumen, petroleum residues, or synthetic resins with added gasoline for this purpose, although other organic substances may also be suitable. The overall mixture is granulated in a known manner. These granules are then heated without admitting air.

Dabei, verdampft das Lösungsmittel, und: die ülbrifgen beigefügten Bestandteile verkoken. Es entsteht so ein festes Granulat, welches weitgehend die gleichen Eigenschaften wie Ruß hat, diesem gegenüber aber den Vorzug aufweist, nicht zu stauben. Es läßt sich daher besonders gut handhaben.In doing so, the solvent evaporates, and: the oil attached Coke constituents. The result is a solid granulate, which is largely the does not have the same properties as carbon black, but has an advantage over it to dust. It can therefore be handled particularly well.

Ein solches Granulat diente bisher ausischließlich der Weiiterverarbeitung, indem es zur Pulverform zerkleinert und dann zu Formkörpern, wie Platten, Kohlebürsten für elektrische Maschinen od. dgl., gepreßt wurde.Such a granulate has so far only been used for processing, by crushing it into powder form and then into shaped bodies, such as plates, carbon brushes For electrical machines or the like. Was pressed.

Es ist nun erkannt worden, daß das Granulat außerordentlich gute Wärmeisolatnonseigenschaften und trotz einer großen Porosität eine erhebliche Härte aufweist. Es behält seine; Eigenschaften auch dann: noch bei, wenn es hohen Temperaturen ausgesetzt wird. Außerdem brennt und gast esi beul dem. hohen Temperaturen nicht, vorausgesetzt, d'aß diese die Temperaturen nicht wesentlich übersteigen, die bei der Granula:tüon angewendet wurden. Da die Granulatiion je nach Wunsch bei Temperaturen bis zu i6od" erfolgt, kann. ein entsprechend behandeltes Erzeugnis auch bei diesen Temperaturen zur Wärmeiisolation benutzt werden.It has now been recognized that the granules have extremely good thermal insulation properties and has a considerable hardness despite a large porosity. It keeps its; Properties even then: even when it is exposed to high temperatures. aside from that burns and guest esi beul dem. high temperatures, provided that these do not substantially exceed the temperatures used in the case of the granules became. Since the granulation, depending on your requirements, at temperatures of up to to i6od "takes place, a correspondingly treated product can also be used at these temperatures can be used for thermal insulation.

Erfindungsgemäß wird daher vorgeschlagen, das Granulat also Wärmeiiso,latiorismittel bzw. als elektrisches zu benutzen.According to the invention, it is therefore proposed that the granulate be heat-treated, latioris medium or to use as an electrical one.

Mit besonderem Vorteil kann es. an drei Stelle von Zirko:noxyd oder ähnlichen Stoffen treten, die beispielsweise zur Wärmeiiso@latlion von Induktionsöfen und Kohlerohräfen dienen.
