Description
Mit einem Metallstift beschreibbares Papier. Bekanntlich kann Papier, auf welches Metallverbindungen wie Zinkweiß, schwefelsaures Barvt oder ein Gemisch dieser beiden Stoffe nach Verreiben mit Fett oder C)1 aufgetragen oder überzogen sind, mit Metallstiften beschrieben werden. Derartige Papiere werden besonders zu Registrierstreifen für Geschwindigkeitsmesser, Indikatoren u. dgl. verwendet. Hierbei zeigt sich aber der Nachteil, daß, da der Metallüberzug verhältnismäßig langsam trocknet, die Schrift unter der Einwirkung von Feuchtigkeit leidet und sehr leicht mit dem angefeuchteten Finger abgewischt werden kann, so daß es z. B. beim Registrieren der Geschwindigkeit von Lokomotiven möglich ist, die Geschwindigkeitsdiagramme zu fälschen. Auch der in den Geschwindigkeitsmesser eindringende Dampf der Lokomotive kann die Aufzeichnungen des Metallstiftes verwischen oder undeutlich machen.Paper that can be written on with a metal pen. It is well known that paper on which metal compounds such as zinc white, sulfuric acid barvt or a mixture these two substances applied or coated after rubbing with fat or C) 1 can be written on with metal pens. Such papers are special too Registration strips for speedometers, indicators and the like. Used. Here but there is the disadvantage that, since the metal coating is relatively slow dries, the writing suffers from the action of moisture and very easily can be wiped with the moistened finger, so that there is z. B. when registering the speed of locomotives is possible using the speed diagrams counterfeit. Also the steam from the locomotive entering the speedometer may blur or obscure the metal pen's records.
U m diesen Nachteil zu beheben, ist erfindungsgemäß die Metallverbindung nicht mit 01 oder Fett, sondern mit einem in Wasser unlöslichen und leicht trocknenden Klebmittel versetzt, das aus in Benzin, Benzol, Äther o. dgl. lösbarem Gummi oder in Alkohol lösbarem Harz besteht. Nach dem Auftragen des Überzuges verdunstet das Lösungsmittel rasch.U m to eliminate this disadvantage, according to the invention the metal compound is not added with 01 or fat, but with a water-insoluble and light-drying adhesive, which consists in gasoline, benzene, ether o. The like. Detachable rubber or releasable in alcohol resin. After the coating has been applied, the solvent evaporates quickly.
Als besonders geeignet bat sich folgende Miscbung erwiesen: Zerkleinerter Rohgummi wird in eine Flasche getan und so viel Benzol aufgegossen, daß man am nächsten Tage eine dicke Lösung erhält. Darauf werden 2o g Zinkweiß mit dieser Gummilösung vermischt und das Ganze 24 Stunden stehengelassen. Nach nochmaliger gründlicher Durchmischung wird die 'Mischung mit etwa zoo g Benzol verdünnt, worauf diese Lösung sofort auf Papier aufgebracht werden kann. Die Trocknung derselben erfolgt sehr rasch.The following mixture proved to be particularly suitable: Crushed Raw rubber is put in a bottle and so much benzene is poured in that one can get the next Days get a thick solution. Then 20 g of zinc white with this rubber solution mixed and left to stand for 24 hours. After more thorough Mixing the 'mixture is diluted with about zoo g of benzene, whereupon this solution can be applied immediately to paper. The drying of the same takes place very much quickly.
Eingehende Versuche haben erwiesen, daß die Schrift, welche auf diesem Papier mit einem derartigen Überzuge durch einen 'Metallstift erhalten wird, unter der Einwirkung von Feuchtigkeit nicht im geringsten leidet.Thorough experiments have shown that the writing based on this Paper with such a coating is obtained by a 'metal pin, under the action of moisture does not suffer in the least.
Es wird ferner besonders bei Verwendung von Gummi noch der Vorteil erzielt, da ß die aufgetragene Schicht äußerst dünn sein kann, nicht spröde und brüchig, sondern verhältnismäßig weich und elastisch ist und den Schreibstift nur verhältnismäßig wenig abnutzt. Da der Überzug ferner sehr rasch trocknet, so entfällt das bisher unumgänglich notwendige langwierige und kostspielige, besondere Trockenanlagen erfordernde Trocknen des Papiers.There is also the advantage especially when using rubber achieved that ß the applied layer can be extremely thin, not brittle and brittle, but relatively soft and elastic and the pen is only relatively little wear. Since the coating dries very quickly, there is no need the lengthy and expensive, special drying systems that have been inevitable up to now requiring drying of the paper.
