Description

Formenpuder. Gegenstand vorliegender Erfindung ist die Verwendung von staubfein gemahlenen Kakaobohnenschalen als Formpuder.Molding powder. The present invention relates to the use from dust-fine ground cocoa bean shells as molding powder.

Die Erfindung beruht darauf, daß die sonst wertlosen, als Abfall behandelten Kakaobohnenschalen auf Grund ihres natürlichen, nicht backenden Fett- oder ölgehaltes in feinster Mahlurig ein wirklich hervorragendes Isoliermittel bilden.The invention is based on the fact that the otherwise worthless, treated as waste Cocoa bean shells due to their natural, non-baking fat or oil content Form a really excellent isolating agent in the finest grind.

Bekanntlich dient als Formpuder in den Eisengießereien für die Herstellung von Maschinengußteilen, insbesondere von kleinen Zahnrädern u. 4g1., das echte Lycopodium.It is well known that it is used as a molding powder in iron foundries for production of machine castings, especially of small gears and 4g1., the real Lycopodium.

Es gibt außerdem viele Ersatzstoffe für das echte Lycopodium; jedoch haben die meisten nicht die vollkommene natürliche Eigenschaft, Wasser abzustoßen; sie müssen vielmehr mit entsprechendem fetthaltigen Stoff imprägniert werden, damit sie keine Feuchtigkeit aufsaugen. Dies ist bei den sich leicht zu staubfeinem Pulver zu vermahlenden Kakaobohnenschälen nicht nötig, da dieselben im Gegensatz zu fast allen anderen Formpudern einen. natürlichen Fettgehalt haben. Nach der Vermahlung kann das Pulver nötigenfalls noch einer Trocknung unterzogen werden.There are also many substitutes for the real Lycopodium; However most do not have the perfect natural ability to repel water; rather, they have to be impregnated with a suitable fatty substance so that they do not absorb moisture. This is the case with powder that is easy to dust No need to grind cocoa bean peel, as the same in contrast to almost all other molding powders one. have natural fat content. After grinding If necessary, the powder can also be subjected to drying.

Gegenüber dein zu .gleichem Zweck bereits bekannten Pulver aus Korkabfällen mit natürlichem Fettgehalt haben die Kakaohohnenschalen Aden Vorzug, daß sie sich wesentlich leichter staubfein mahlen lassen.Compared to your already known powder made from cork waste for the same purpose With a natural fat content, the Aden cocoa bean shells have the advantage that they are themselves It is much easier to grind to a fine dust.
