Effect of Surfactants on the Yield Percentage of Spherical Cellulose Beads
Translated Abstract
The kinds and dosage of the surfactants have great effect on the globulation process of the spherical cellulose beads. Therefore, a comprehensive study regarding the effect of different kinds of surfactants and their consumption has been conducted using the dispersants, i.e., Span 85, Tween 80, Tween 85, Span 80, sodium oleate and their compound mixtures, spherical cellulose beads prepared by sequential cooling technique and N-methylmorpholine-N-oxide (NMMO) as materials. The results indicated that the best dispersion efficiency could be achieved when choosing 1.0% of Tween 85 as dispersant, the highest yield percentage of cellulose beads was 98.5%. Additionally, using 4.0% of the mixture of Tween 85 and sodium dodecyl sulfonate, the yield percentage of cellulose beads could reach 96.6%. For the mixture of Span 85 and Tween 80, sodium dodecyl benzene sulfonate and sodium dodecyl sulfonate as dispersants, the yield percentages of cellulose beads could also reach 95.8% and 80.0% respectively with a dosage of 1.5%.
