Table 4.
Values of power law model parameters (ηa,50, K, and n) of raw and agglomerated PPSPs with different concentrations of MD binder.
| Sample | MD Concentration (%) |
ηa,50 (Pa·s) | K (Pa·sn) | n |
|---|---|---|---|---|
| Raw PPSP | 1.47 ± 0.02 c | 4.78 ± 0.17 ab | 0.70 ± 0.01 d | |
| Agglomerated PPSP |
0 (control) | 1.67 ± 0.02 a | 4.89 ± 0.01 a | 0.73 ± 0.00 c |
| 10 | 1.58 ± 0.06 b | 4.70 ± 0.02 b | 0.72 ± 0.01 c | |
| 20 | 1.10 ± 0.02 d | 3.18 ± 0.10 c | 0.73 ± 0.00 c | |
| 30 | 0.76 ± 0.01 e | 1.45 ± 0.07 d | 0.77 ± 0.00 b | |
| 40 | 0.59 ± 0.00 f | 1.33 ± 0.07 d | 0.79 ± 0.01 a |
Each value is the mean of triplicate measurements ± SD. Means with different lowercase letters (a–f) within each column are significantly different (p < 0.05).
