Flow curves of well deflocculated kaolin suspensions with different solids contents were measured by rotational viscometry (RotoVisco 1 with concentric cylindrical sensor Z41, ThermoHaake GmbH, Germany) in the shear rate range between 0 and 1000 [s.sup.-1].
Figure 4 (top to bottom) shows the flow curves of optimally deflocculated kaolin suspensions in dependence of the solids content (kaolin volume fraction).
Ashoke SenGupta of Amcol Health & Beauty Solutions said using Magnasperse gel in the oil phase of a cosmetic formulation caused deflocculated suspended pigments, a thickened oil phase, a more stable emulsion, excellent spreading and a longer shelf life.
In spray washing systems, the deflocculated soil floating on the reservoir surface can be periodically removed, while clean solution is drawn from below the soil layer for spraying.
The glaze firings are to cone 10 using a deflocculated glaze recipe for practical purposes.
Microfossils: For chironomid analysis, a measured amount of freeze-dried sediment was rehydrated and deflocculated in a warm 5% KOH solution for approximately 20 min, then rinsed through a 74 [micro]m mesh sieve.
The same outcome is present with slip casting formulas that are over deflocculated with sodium compounds such as sodium silicate, soda ash, Darvan #811, or Darvan #7 (sodium polyelectrolyte), all of which are soluble.
Ceramic monoprints are created when underglaze or slip is printed on a plaster slab and deflocculated slip is poured over the image.
Monoprints can be worked, but the limits of deflocculated clay and the desire to preserve the fragile image discourage manipulation into complex forms.
This formula is deflocculated with Darvan 811 and casts best with a specific gravity of 1.78-1.80 CDG C-57 White Gloss cone 5-7 Frit 3134 50 EPK 30 Flint 20 Total 100 Zircopax 15
