Description

Verfahren zum Konzentrieren von Kautschukmilchsaft. In dem Patent 414210 ist ein Verfahren zur Konzentrierung von Kautschukmilchsaft mittels gewisser Pflanzenschleime und anderer kolloidhaltiger Substanzen beschrieben, welches eine Anreicherung von nicht koagulierter Kautschuksubstanzen durch Ausbildung getrennter Flüssigkeitsschichten bewirkt.Method for concentrating rubber milk juice. In the patent 414210 is a method for concentrating rubber milk juice by means of certain Plant slimes and other colloid-containing substances described which one Enrichment of non-coagulated rubber substances through the formation of separate ones Liquid layers causes.

Das vorliegende Verfahren beruht auf der Benutzung der vorgenannten Substanzen (Pflanzenschleim usw.) zur Herstellung zusammenhängender Kautschukschichten und stellt also eine Erweiterung der durch Patent 414210 geschützten Erfindung dar, derart, daß die Konzentrierung bis zur Koagulation getrieben wird.The present method is based on the use of the aforementioned Substances (plant slime, etc.) for the production of coherent rubber layers and thus represents an extension of the invention protected by patent 414210, such that the concentration is driven to coagulation.

Die Ausführung des neuen Verfahrens geschieht derart, daß man hinreichend konzentrierte wäßrige Gele von Gelatine und anderen Kolloiden darstellt, und Latex bzw. nach dem Verfahren des Hauptpatentes konzentrierte Latexsahne mit der Oberfläche der Gele, welche eine glatte Fläche darstellt, so lange in Berührung läßt, bis sich aus dem Latex oder der Latexsahne eine zusammenhaftende feste Schicht gebildet hat.The execution of the new method is done in such a way that one suffices represents concentrated aqueous gels of gelatin and other colloids, and latex or according to the process of the main patent, concentrated latex cream with the surface of the gel, which is a smooth surface, is left in contact until has formed a cohesive solid layer from the latex or latex cream.

Mit Vorteil kann bei der Herstellung der Gele eine Zumischung von@Glyzerin, Melasse, auch sonstigen wasserentziehenden Mitteln angewandt werden.An admixture of @glycerin, Molasses as well as other dehydrating agents can be used.

Man läßt beispielsweise in einer Kristallisierschale von etwa 20 cm Durchmesser Zoo ccm einer wä.ßrigen ro- bis aoprozentigen Gelatinelösung gelieren und gießt darauf, je nach der Dicke der Latexhaut, welche man erzielen will, mindestens so viel Latex, daß die Oberfläche des Gels vom Latex völlig bedeckt ist; so kann man je nach der Latexmenge, welche man eingegossen hat, in 3o Minuten oder bei dickeren Kautschukschichten von o,5 bis r mm Dicke erst nach bis 3 Stunden eine zusammenhängende Kautschukschicht von dem Gelatinegel abziehen. Die auf die beschriebene Weise hergestellten Kautschukhäute können auf beliebige Weise getrocknet und vulkanisiert werden. Es können die Gele gegebenenfalls unter Erwärmen wieder vom überflüssigen Wasser befreit und wieder benutzbar gemacht werden.One leaves, for example, in a crystallizing dish of about 20 cm Diameter zoo ccm of an aqueous ro- to ao-percent gelatin solution gel and pour on it, at least according to the thickness of the latex skin which one wants to achieve so much latex that the surface of the gel is completely covered by the latex; so can depending on the amount of latex that has been poured in, in 30 minutes or thicker Rubber layers from 0.5 to r mm thick only become coherent after up to 3 hours Peel the rubber layer from the gelatin gel. Those produced in the manner described Rubber skins can be dried and vulcanized in any way. It If necessary, the gels can be freed from the excess water again by heating and made usable again.
