Abstract

Micro-rheological properties including elasticity index (EI) and solid liquid balance (SLB) of gelation process of hydrophobic amphoteric cellulose solution at different temperatures and crosslinker concentrations were investigated by optical micro-rheometer in this work. During the crosslinking gelation process, EI appears a two-stage rise, and SLB first increases to maximum and then decreases to constant. According to EI curves, the gelation process can be divided into two stages. Intrinsic rheo-kinetics equations were first established to characterize the two-stage crosslinking process. The simulated values by the novel intrinsic rheo-kinetic models were in good agreement with experimental data and the model parameters were well-defined and of reasonable significance.
