Title: A method to correlate floc size to rheological characteristics of microfibrillated cellulose water suspensions
Abstract: Microfibrillated cellulose (MFC) water suspensions were characterized in a rheometer using transparent geometry which allowed the observation of the suspension’s flocculated structure and the structural changes. The shear rates 500, 30, and 5 1/s induced different floc structures, whereas shear rate 0.5 1/s preserved the structure from the previous shear rate. MFC’s degree of fibrillation was reflected in the coarseness of the floc structure. The viscosity of the suspension at a given shear rate was dependent on the floc structure.
