Description
In kaltem Wasser löslicher Leim Die Erfindung- hat einen in kaltem Wasser löslichen Leim zum Gegenstande, welcher aus einem trockenen, innigen. Gemisch von Sojabohneneiweiß und basisch reagierenden Alkalisalzen, vorzugsweise in calciniertem Zustande, besteht.Cold Water Soluble Glue The invention - has one in cold water Water-soluble glue to the object, which consists of a dry, intimate. mixture of soybean protein and basic alkali salts, preferably in calcined Condition exists.
Der Vorteil dieses Leimes besteht darin, daß er durch Anrühren mit kaltem Wasser in verhältnismäßig kurzer Zeit in Lösung geht und dabei eine hohe Zugfestigkeit besitzt.The advantage of this glue is that it can be mixed with cold water in a relatively short time goes into solution and thereby a high Has tensile strength.
Rührt man z. B. eine Mischung von ioo Teilen aus den Sojabohnen herrührendes Pflanzeneiweiß und 2o Teilen kristallwasserfreiem Ammoniumcarbonat mit Wasser bei Zimmertemperatur an, so ist die Lösung nach etwa i Stunde vollendet und ein gebrauchsfertiger Leim entstanden. Bei Anwendung von Milchcasein an Stelle von Pflanzeneiweiß in gleichen Mengen und unter sonst gleichen Bedingungen dauert es mindestens 2q. Stunden, bis ein gebrauchsfertiger Leim erhalten werden kann.If you stir z. B. a mixture of 100 parts derived from the soybeans Vegetable protein and 2o parts of anhydrous ammonium carbonate with water Room temperature, the solution is complete after about an hour and is ready for use Glue emerged. When using milk casein instead of vegetable protein in the same Quantities and other things being equal, it takes at least 2q. Hours until a ready-to-use glue can be obtained.
Zur Herstellung des Leimes können außer Ammoniumcarbonat auch andere Alkalien bzw. alkalische Salze Verwendung finden, z. B. Natrium- oder Kaliumcarbonat, zweckmäßig in calciniertem Zustande.In addition to ammonium carbonate, other types of glue can also be used to produce the glue Alkalis or alkaline salts are used, e.g. B. sodium or potassium carbonate, expediently in the calcined state.
Weiter läßt sich das Verfahren auch so ausführen, daß zu dem ausgefällten, noch feuchten Eiweiß vor dem Trocknen eine berechnete Menge eines der alkalischen Salze zugesetzt wird, und zwar zweckmäßig ebenfalls in calciniertetn Zustande: Diese Salze binden einen großen Teil des in dem Eiweiß enthaltenen Wassers und erleichtern hierdurch die nachträgliche Trocknung außerordentlich.The method can also be carried out in such a way that the precipitated, still moist egg whites before drying a calculated amount of one of the alkaline Salts is added, expediently also in the calcined state: These Salts bind a large part of the water contained in the protein and make it easier as a result, the subsequent drying is extraordinary.
Beispiel i ioo Teile trockenes Eiweißpulver werden mit 2o Teilen calciniertem Ammoniumcarbonat gemischt.EXAMPLE 100 parts of dry protein powder are calcined with 20 parts Ammonium carbonate mixed.
Beispiel e zoo Teile aus entöltem Sojaschrot herrührendes feuchtes Eiweiß mit einem Wassergehalt von 75 °1o werden mit io Teilen calciniertem Natriumcarbonat gemischt und hierauf unter vermindertem Luftdruck getrocknet.Example e zoo parts of moist soybean meal originating from de-oiled Egg whites with a water content of 75 ° 10 are mixed with 10 parts of calcined sodium carbonate mixed and then dried under reduced air pressure.
