VISCOSITY OF PULP (CAPILLARY VISCOMETER METHOD)

• Procedure for determining the viscosity of 0.5% cellulose solutions, using 0.5 M Cupriethylenediamine as a solvent and a capillary viscometer.
• Measurements may be made on bleached cotton and wood pulps.
• Applicable of this procedure to extended delignification pulps has not been determined Technique involves mechanical shaking of the sample-solvent mixture in a closed bottle . Containing glass beads.
• Next technique involves stirring the sample and solvent in an open tube with a copper rod.
• Viscosity of a pulp gives the average degree of polymerization of the cellulose.
