| Abstract:By studying the effects of parallel sampling, drying method, test method of viscosity, high and low viscosity of the pulp and base types of cooking liquor on determination results of dynamic viscosity and intrinsic viscosity, the applicability and accuracy of two viscosity testing methods, i.e. dynamic viscosity measurement using cuprammonium solution, and intrinsic viscosity measurement using cupri-ethylenediamine solution, were compered and analyzed. A viscosity determination method suitable for sulfite dissolving pulp was obtained. The results indicated that for the viscosity determination of sulfite wood pulp, the accuracy of viscosity determination was able to be improved by adopting intrinsic viscosity determination method, air drying method and multiple sampling. |
