Description
Platten, Zylinder usw., die auf ihrer Oberfläche zur Aufnahme und Wiedergabe von Zeichnungen, Zeichen, Eindrücken usw. bestimmt sind Die Beschaffenheit und Eigenschaften von Platten, Walzen oder sonstigen Formstücken, die Zeichnungen, Zeichen, Eindrücke usw. auf ihrer Oberfläche haben, die z. B. im graphischen Gewerbe zur Wiedergabe von Zeichnungen Verwendung finden. sollen, oder z. B. von Schallplatten in der Schallplattenindustrie, hängen, abgesehen von den verwendeten Bindemitteln, Harzen, Kunstharzen, Kunstmassen usw., sehr stark von dem gewählten Füllstoff ab. Die hierbei: oftmals beobachteten unangenehmen Erscheinungen sind, wie sich herausgestellt hat, auf die Korngröße dieser Füllmaterialien zurückzuführen. Es wurde gefunden, daß die Anwendung von Füllmaterialien von einer Feinheit, die weit größer ist als die, die bisher allgemein als gut angesprochen worden ist, eine erhebliche Verbesserung dieser Platten usw. bedingt. Diese sehr feine und gleichmäßige Verteilung haben vorzugsweise die Stoffe, ätile unter besonderen Kautelen, um diese Feinheit zu erzielen (sei es auf chemischem Wege durch Fällung aus Lösungen, sei es aufs dem Gaszustande), zur Abscheidung gebracht worden sind. Durch die modernen Verfahren zum Feinmahlen und Sichten sowie Schlämmen ist es auch möglich, aus natürlichen Produkten diese außerordentlich fein verteilten Stoffe herauszusondern. Besonders günstig ist das Titandioxyd, weil dies gleichzeitig die Eigenschaft hat, sich in harzartige Massen besonders leicht einarbeiten zu lassen und auch das Einarbeiten anderer, schwer einzumengender, feinverteilter Pulver in. Mischung mit diesen sehr erleichtert.Plates, cylinders, etc., which are on their surface for receiving and Reproduction of drawings, characters, impressions, etc. are intended for the quality and properties of plates, rollers or other shaped pieces, the drawings, Have characters, impressions, etc. on their surface which e.g. B. in the graphic industry used to reproduce drawings. should, or z. B. of records in the record industry, apart from the binders used, Resins, synthetic resins, synthetic compounds, etc., depend very much on the filler chosen. The unpleasant phenomena often observed here are, as it turned out has to be attributed to the grain size of these filler materials. It was found, that the use of filling materials of a fineness which is far greater than that which has so far been generally considered good is a significant improvement of these plates, etc. conditionally. Have this very fine and even distribution preferably the fabrics, ätile with special caution, in order to achieve this fineness (be it by chemical means by precipitation from solutions, be it by the gas state), have been brought to the deposition. Through the modern methods of fine grinding and sifting as well as silting it is also possible to make these from natural products to separate out extremely finely divided substances. This is particularly cheap Titanium dioxide, because this also has the property of turning into resin-like masses easy to incorporate and also difficult to incorporate others finely divided powder to be mixed in. Mixing with these is very easy.
Die Anwendung von Titandioxyd und von anderen weißen. Pigmenten, die neuerdings in außerordentlich feiner Verteilung technisch hergestellt werden, ist zum Weißfärben von Schablonen bereits vorgeschlagen worden. Die Anwendung dieser Pigmente geschah nur, weil diese ein sehr hohes Weißfärbevermögen besitzen, nicht aber, weil :erkannt worden war, was Gegenstand .der vorliegenden Erfindung ist, daß nämlich die feinste Verteilung der Pigmente (Teilchengröße unter r #L) den beschriebenen großen technischen Fortschritt in der Beschaffenheit von - Platten, Zylindern usw. bringt, deren Oberfläche zur Aufnahme und Wiedergabe von Zeichnungen, Zeichen usw. bestimmt ist. Die vorliegende Erfindung ist auch nicht auf die Anwendung weißer Pigmente beschränkt.The use of titanium dioxide and other white ones. Pigments that have recently been produced technically in an extraordinarily fine distribution for whitening stencils have already been proposed. Applying this Pigments only happened because they have a very high whitening power, not but, because: it was recognized what is the subject of the present invention, namely that the finest distribution of the pigments (particle size below r #L) the one described great technical progress in the nature of - plates, cylinders, etc. brings whose surface for recording and reproducing drawings, characters, etc. is determined. The present invention is also not applicable to the application of whiter Pigments limited.
