Summary

A sample container assembly was fabricated for viscosity measurements of settling suspensions. Effect of zeta potential on the apparent viscosity of glass particles suspended in water was studied. The maximum concentration was 44% by weight. Zeta potential was varied using AlCl3 and NaOH in the range of −80 to +40 mV. There was a definite effect of the surface charge, the variation in the apparent viscosity for the maximum concentration of glass particles was from 2.02 to 4.20 cp.

Zusammenfassung

Es wurde die Viskosität von Suspensionen gröberer Glaspartikel in Wasser gemessen Durch Zugabe von AlCl3 und NaOH wurde das Zeta-Potential von −80 mV bis +40 mV verändert und der Einfluß dieser Änderung auf die Viskosität untersucht.
