Description

Zusatz zum Patente 197154 vom 24. Juli 1906.Addendum to patent 197154 of July 24, 1906.

Patentiert im Deutschen Reiche vom 11. November 1906 ab. Längste Dauer: 23.JuIi 1921. Patented in the German Empire on November 11, 1906. Longest duration: July 23, 1921.

Gegenstand der vorliegenden Erfindung betrifft eine Verbesserung des Verfahrens nach Patent 197154.The present invention relates to an improvement of the method according to Patent 197154.

Nach Patent 197154 wird durch Behandeln von Altgummi oder Gummiabfällen mit Kaufschuklösungsmitteln, alkalischen Flüssigkeiten und Wasserdampf eine schmierige Kautschukmasse erhalten, welche dann weiter durch Erhitzen mit Wasser unter Druck in filtrierbare Flüssigkeiten übergeführt ,wird.According to patent 197154, by treating of old rubber or rubber waste with purchase shoe solvents, alkaline liquids and water vapor get a greasy rubber mass, which then continues through Heating with water under pressure is converted into filterable liquids.

Es hat sich nun herausgestellt, daß in vielen Fällen eine Anwendung von Druck nicht nötig ist, sondern schon ein Aufrühren der schmierigen Masse mit heißem Wasser, gelegentlich sogar Aufrühren mit kaltem Wasser, genügt.It has now been found that in many cases an application of pressure is not necessary, but a stirring of the greasy mass with hot water, Occasionally even stirring with cold water is sufficient.

In welchen Fällen die eine oder die andereIn what cases one or the other

Art des Lösungsverfahrens gewählt werden muß, ist durch einen einfachen Vorversuch festzustellen, da bei der großen Ungleichmäßigkeit des Rohmaterials, wenn man von Altgummi ausgeht, eine sehr verschieden geartete schmierige Kautschukmasse entsteht, was ja in Rücksicht auf die verschiedene Herkunft des in dem Rohmaterial enthaltenen Gummis sowie der starken Verschiedenheit der Verunreinigungen und Zusätze, die in dem Altgummi enthalten sind, sich leicht erklärt. The type of solution that needs to be chosen is through a simple preliminary experiment noticeable because of the great unevenness of the raw material when looking from Old rubber runs out, a very different type of greasy rubber compound is created, what in consideration of the different origins of what is contained in the raw material Gums as well as the wide variety of impurities and additives that are used in the scrap rubber is easily explained.
