Description

Lautschriftträger, Schallplatte o. dgl. Es ist bekannt, die Massen für Lautschriftträger mit Füllstoffen zu versehen, die ganz oder teilweise aus Metalloxyden bestehen. Gemäß der Erfindung wird als Metalloxyd für diese Zwecke Titandioxyd verwendet. Die Qualität der Lautschriftträger, Schallplatten usw. wird bei Verwendung von Titandioxyd eine wesentlich bessere, insbesondere werden die Nebengeräusche fast ganz beseitigt.Phonetic carrier, record or the like. It is known the masses for phonetic carriers to be provided with fillers that are wholly or partly made of metal oxides exist. According to the invention, titanium dioxide is used as the metal oxide for these purposes. The quality of phonetic carriers, records, etc. is reduced when using titanium dioxide a much better one, in particular the background noise is almost completely eliminated.

Weiterhin erleichtert das Titandioxyd den Walz- und Knetprozeß zum Einverleiben der mineralischen Substanzen in die Bindemittel, aus denen die Lautschriftträger, Schallplatten usw. hergestellt werden.Furthermore, the titanium dioxide facilitates the rolling and kneading process for Incorporation of the mineral substances into the binders from which the phonetic carriers, Records etc. are made.

Man kann das Titandioxyd (Ti02) in reinem Zustande zu den Platten verwenden, in Mischung mit anderen Füllmaterialien, wie Bariumsulfat, Ton usw., und auch unter Zumischung von Ruß. Metalloxyde, insbesondere Eisenoxyd, und die Oxyde der Elemente der Eisengruppe sind bereits bei der Herstellung von Schallplatten verwendet worden, wobei das natürliche Eisenoxyd sich noch als das beste erwiesen hat. Die besonders günstige Wirkung des Titandioxyds gegenüber diesen Metalloxyden dürfte teils an der Feinheit und Gleichmäßigkeit des Kornes, teils an der besonderen Beschaffenheit der Kristallform, Härte und Oberflächenbeschaffenheit des Titandioxyds liegen.The titanium dioxide (Ti02) can be added to the plates in a pure state use, mixed with other filling materials, such as barium sulfate, clay, etc., and also with the addition of soot. Metal oxides, especially iron oxide, and the Oxides of the elements of the iron group are already used in the production of records has been used, the natural iron oxide still proving to be the best Has. The particularly beneficial effect of titanium dioxide on these metal oxides probably due partly to the fineness and evenness of the grain, partly to the special Nature of the crystal form, hardness and surface quality of the titanium dioxide lie.
