Abstract
Description
ξ = Masse Rückstand/Ausgangsmasse der dem Impact ausgesetzten Probe.
Auf 1 Liter zur Herstellung der Suspension verwendeten Wassers wird der Gehalt an mineralischem Material, ausgedrückt durch das Verhältnis Al2O3 Wasser konstant auf 24 Gew.-% gehalten. Der Chargengehalt ist variabel zwischen dem Maximalwert von 30 Gew.-% und dem Fehlen von Charge (0 Gew.-%), wie in der nachstehenden Tafel 1 angegeben. Das Komplement wird gebildet durch mikrokristallinen Boehmit oder auch Pseudoboehmit vom Typ PURAL SB, der von der Firma CONDEA gelie fert wird. Die kristallographische Natur der Charge ist in Tafel 1 präzisiert.
Organische Phase/Wasser = variabel (siehe Tafel 1)
Oberflächenaktives Mittel/organische Phase = 2 Gew.-%
