Paper360 - September/October 2016 - 59

This research confirms findings of others in respect to the influence of additives like polyelectrolytes and pigment particles on MNFC suspension rheology. However, previously unreported effects are described for polyelectrolyte treated pigment particles, indicating an increased interaction with MNFC to the advantage of future products, such as fibrillar-based nanocomposites. Proposed conformations for MNFC suspensions with and without CMC and/or pigment. Blue halos around fibers indicate their interaction potential; red halos indicate altering of the fiber-fiber interaction potential related to CMC presence.

Ong, James D. Ede, Theodore H. Wegner, and Michael Goergen CELLULOSE NANOFIBRILS Effects of mechanical fibrillation time by disk grinding on the properties of cellulose nanofibrils Qianqian Wang and J.Y. Zhu Cellulose nanofibrils (CNF) were successfully produced from a bleach kraft eucalyptus pulp by a supermasscolloider. Effects of grinding time on structure and properties of CNF and the corresponding CNF films were investigated. Grinding time was important to increase the optical transparency of CNF suspensions. The degree of polymerization (DP) and crystallinity index (CrI) of CNF decreased linearly with the increase in CNF suspension transparency. This suggests optical transparency of a CNF suspension can be used to characterize the degree of fibrillation. Specific tensile strength and Young's modulus of the CNF films made of CNF suspension with only 0.5 h grinding were increased approximately 30 percent and 200 percent, respectively, compared with conventional handsheets prepared by valley beating to 300 CSF. Grinding beyond 0.5 h produced negligible improvement in specific tensile and specific modulus. Opacity of CNF films decreased rapidly during the first 1.5 h of fibrillation and then plateaued. This research indicates that disk milling time affects the morphology of cellulose nanofibrils as well as the optical and mechanical properties of film made of the resultant fibrils. JULY Impacts of fibrillation time on CNF films' optical and strength properties. PROCESS CONTROL Commissioning brownstock washing controls for an evaporator limited mill Ricardo B. Santos and Peter W. Hart An automated shower water control system has been implemented to reduce the volume and variability of weak black liquor being sent from the pulp mill to the evaporators. The washing controls attempt to balance the need for consistent and low soda carryover to the bleach plant with consistently high weak black liquor solids being sent to the evaporators. The washer controls were implemented on two bleachable grade hardwood lines (one with oxygen delignification, one without oxygen delignification) and one pine line. Implementation of the control program resulted in an increase in black liquor solids of 0.6 percentage points for the hardwood lines. Significant foam reduction was realized on the pine line since the pine black liquor solids were able to be consistently maintained just below the soap separation point.
