SILVEIRA, Maria Teresa; FERREIRA, Abel G.M.  and  LOBO, Lélio Q.. The Viscosity of Aqueous Suspensions of Cellulose Fibres.: Part 3. Influence of pH. Silva Lus. [online]. 2003, vol.11, n.2, pp.201-206. ISSN 0870-6352.

The viscosity of aqueous suspensions of cellulose fibres from eucalipt and pine bleached kraft pulps has been measured at 25ºC as a function of consistency and pH. The measurements cover the range of 0.05 up to 1.00 mass per cent consistency and span the pH interval from about 2 to about 12. Empirical correlations have been established between the viscosity of the suspensions and the above mentioned properties.

Keywords : viscosity; suspensions; eucalypt; pine; consistency; fibre length; pH.
