Die bekannten Vervielfältigungsmassen aus Kaolin und Glycerin haben die Eigenschaft, daß ihre Oberfläche mit der Zeit rauh und rissig wird. Es ist daher vorgeschlagen worden, der Masse Chlorcalcium beizugeben, in der Voraussetzung, daß dieser Stoff als besonders hygroskopisch das Austrocknen der Vervielfältigungsmasse verhindern wird.The well-known duplicating materials made of kaolin and glycerine have the property that their surface becomes rough and cracked over time. It is therefore suggested been to add calcium chloride to the mass, provided that this substance is considered to be particularly hygroscopic will prevent the duplication mass from drying out.
Durch Versuche wurde festgestellt, daßExperiments have shown that
ίο das Austrocknen der Vervielfältigungsmasse vermieden werden kann, wenn man der Mischung von Kaolin und Glycerin Zinksulfat zusetzt. Dadurch wird eine zu starke Wasseranziehung ebenfalls verhindert und erreicht, daß eine große Zahl sehr kräftiger Abzüge sogar mit Schriften in gewöhnlicher Tinte gewonnen werden können.ίο the drying up of the duplication mass can be avoided by adding zinc sulfate to the mixture of kaolin and glycerin. This makes one too strong Water attraction also prevents and makes a large number very vigorous Prints can even be obtained with fonts in ordinary ink.
Um eine gelbliche Färbung der abgezogenen Papierblätter zu vermeiden, wird der Masse bei ihrer Herstellung eine geringe Quantität Indigo einverleibt, so daß die Farbe der Masse einen Stich ins Blaue erhält und der Farbe des gebräuchlichen Papiers entspricht. Letztere Beimischung bildet jedoch keinen Teil der vorliegenden Erfindung.In order to avoid a yellowish coloration of the peeled off paper sheets, the mass incorporated a small quantity of indigo in their manufacture, so that the color of the Mass receives a blue tinge and corresponds to the color of the paper in use. However, the latter admixture does not form part of the present invention.
Als die zweckmäßigste Zusammensetzung hat sich folgende bewährt:The following has proven to be the most appropriate composition:
In 100 Gewichtsteile Glycerin werden 225 bis 3°° Gewichtsteile gepulvertes Kaolin eingeknetet, und dann wird der Masse ungefähr 1J2 bis ι Gewichtsteil Zinksulfat beigemischt. Das Zinksulfat wird am besten vorher in pulverförmigem Zustande mit etwas Glycerin und der zur Verwendung kommenden geringen Menge Indigo in einem emaillierten Gefäß1 angerieben. Zum Kneten der Masse wird irgend eine bekannte Mischmaschine benutzt, und zwar bringt man in die Maschine zuerst das Glycerin ein und dann nach und nach während des Durcharbeitens das pulverisierte Kaolin, welches zweckmäßig durch ein über den Einfüllrumpf der Maschine angeordnetes Sieb eingegeben wird. Ist das Kaolin mit dem Glycerin genügend verarbeitet, so wird das mit Glycerin angeriebene Zinksulfat dazugegeben und in der gleichen Weise durchgearbeitet. Die fertige Masse wird dann in Formen (Blechkästen) gefüllt.225 to 3 parts by weight of powdered kaolin are kneaded into 100 parts by weight of glycerol, and about 1 1/2 to 1 part by weight of zinc sulfate is then added to the mass. The zinc sulphate is best rubbed in a powdered state with a little glycerine and the small amount of indigo that is used in an enamelled vessel 1. Any known mixing machine is used to knead the mass, namely first the glycerine is introduced into the machine and then gradually the pulverized kaolin, which is expediently introduced through a sieve placed over the feed tube of the machine, as it is worked through. Once the kaolin has been sufficiently processed with the glycerine, the zinc sulphate rubbed with glycerine is added and worked through in the same way. The finished mass is then filled into molds (sheet metal boxes).
