Abstract

Es wird ein organisches Verdickungs- und Suspensionshilfsmittel hergestellt. Dazu wird in einer Scheibenmühle mit hartmineralischen gekörnten Mahlscheiben (11, 12) eine Suspension aus organischen Faserstoffen mit fibrillärer Faserstruktur mehrfach bei erhöhter Temperatur und erhöhtem Druck gemahlen.
