Da vulkanisierter Kautschuk je nach den Zusätzen, welche die Fabrikanten beimengen, sehr verschiedene Zusammensetzungen aufweist, dauert das   Entvulkanisieren     längere oder kürzere Zeit und muss man öfters die Kalk- oder Cementmongo verdoppeln oder selbst noch weiter erhöhe !). In manchen Fällen muss man auch eines der bekannten   Hilfsmittel wie Zucker, Bleisalze, Baryt. Glycerin, Ätzalkalien oder Alkalicarbonate zusetzen, je nach den dem Kautschuk beigemengten Substanzen. Diese Hilfsmittel werden dem Kalkbade zugesetzt.

Since vulcanized rubber has very different compositions depending on the additives that the manufacturers add, the devulcanization takes longer or shorter time and you often have to double the lime or cement mongo or even increase it!). In some cases you also have to use one of the well-known aids such as sugar, lead salts, barite. Add glycerine, caustic alkalis or alkali carbonates, depending on the substances added to the rubber. These aids are added to the lime bath.

Claims (1)

PATENT-ANSPRUCH : Yorfahreu zum Entvulkanisieren des Kautschuks, dadurch gekennzeichnet, dass man den zu verarbeitenden Kautschuk in Wasser einlegt, in welches vorher ausgeglühtes Calciumoxyd oder eine dieses Oxyd enthaltende Substanz, wie Cement, eingebracht wurde, das Wasser hierauf bis zum Kochen erhitzt und einige Zeit kochen lässt. PATENT CLAIM: Yorfahreu for devulcanizing the rubber, characterized in that the rubber to be processed is placed in water into which previously calcined calcium oxide or a substance containing this oxide, such as cement, has been introduced, the water is then heated to boiling and some Let time boil.
