wird. Die Lösung wird dadurch dicker und von dunkler Cremefarbe.
Nun. wird das Gemisch von Teer und Pech und Teeröl der Kaseinlösung sehr langsam unter langsamem Rühren zugesetzt, worauf man das Ganz2 während ungefähr fünf Minuten zum Sieden erhitzt und dann bis zur gewünschten Konsistenz durch Zusatz von 200 bis 500 Teilen Wasser abkühlt. Das Produkt hält sich unbegrenzte Zeit in Suspension und ist mit Wasser bis zur gewünschten Verdünnung beliebig mischbar. Gegebenenfalls kann man der Teeröl enthaltenden Harz-Saifen-Kaseinlösung, bevor man sie mit dem Gemisch von Teer, Pech und Teeröl versetzt, 5-10 Teile Karbolsäure zusetzen, wodurch die Lösung viskoser wird.
Wenn die Mischung als Bindemittel zur Herstellung von Briketts verwendet werden soll, kann der Teer durch hartes oder weiches Bitumen und Pech ersetzt werden.
EMI2.2
kann ein Bitumen verwendet und die Mischung durch Zusatz von Erd-oder Anilinfarben gefärbt werden : diese Mischungen können auch zum Anstrichen und Wasserdichtmachen von Holz, Ziegeln, Stein, Betongebäuden u. dgl. angewendet werden.
Es wird besonders darauf hingewiesen, dass bei der Herstellung der Kaseinmischung das Ätzkalkali in zwei Teilen zugesetzt wird ; würde das ganze Alkali zugleich zugesetzt werden, so wäre die Gefahr vorhanden, dass das Kasein angegriffen und die emulgierende Wirkung beeinträchtigt wird.
Es ist auch wichtig, dass die Teer-, Pech-oder B : tumenmischung sehr langsam unter Rühren der Kaseinmischung'zugesetzt wird, um eine gute Emulgierung zu gewährleisten.
Die verwendeten Teeröle sollen vorzugsweise einen hohen Gehalt an Naphthalin, etwa 8-10. aufweisen.

becomes. This makes the solution thicker and darker cream in color.
Now. the mixture of tar and pitch and tar oil is added to the casein solution very slowly with slow stirring, whereupon the whole2 is heated to boiling for about five minutes and then cooled to the desired consistency by adding 200 to 500 parts of water. The product remains in suspension indefinitely and can be mixed with water up to the desired dilution. Optionally, before adding the mixture of tar, pitch and tar oil to the resin-saifen-casein solution containing tar oil, 5-10 parts of carbolic acid can be added, which makes the solution more viscous.
If the mixture is to be used as a binding agent for the production of briquettes, the tar can be replaced by hard or soft bitumen and pitch.
EMI2.2
Bitumen can be used and the mixture can be colored by adding earth or aniline paints: these mixtures can also be used for painting and waterproofing wood, bricks, stone, concrete buildings and the like. Like. Be applied.
Attention is drawn to the fact that the caustic lime is added in two parts when making the casein mixture; If all the alkali were added at the same time, there would be a risk that the casein would be attacked and the emulsifying effect would be impaired.
It is also important that the tar, pitch or cement mixture is added very slowly to the casein mixture while stirring, in order to ensure good emulsification.
The tar oils used should preferably have a high naphthalene content, about 8-10. exhibit.
