Abstract:
:This work studied the influence of refining on various pulp properties such as freeness, specific surface area, specific volume, water retention value, surface charge, total charge and tensile index of five different pulps. At a freeness level the wheat straw pulp exhibited higher surface charge and total charge compared to other pulps. The specific surface area, specific volume and water retention value of the pulps increased with increased refining. The total fibre charge as determined by conductometric titrations was not affected by refining. However, the surface charge as determined by titrations with poly-DADMAC increased with refining. The increases in specific surface area of pulps by refining resulted in a higher fibre surface charge and also better fibre-fibre bonding. The linear regression models developed using experimental data were found to be accurate. The comparison of model predicted data and the experimental data showed an excellent agreement between them.
