INTERRELATION OF INDIVIDUAL PAPER-FORMING PROPERTIES AND THE DYNAMIC VISCOSITY COEFFICIENT DURING THE GRINDING OF THE FIBROUS MASS
UDC 676.024
Abstract
The refining process is associated with the movement of large masses of fibrous suspensions in the working bodies of refining machines, which affects both the refining process itself and energy consumption when moving the fibrous suspension. In this regard, the efficiency of refining equipment can be ensured on the basis of knowledge of the hydrodynamic processes that occur during the interaction of the working bodies of refining equipment with a fibrous suspension.
During the flow of fibrous suspensions, the basic rheological feature is their viscosity, which makes it possible to judge the internal forces acting in the flow. This is especially important for the bladeless refining method using the “jet-barrier” installation.
In order to most fully judge the direction of the refining process (in the direction of the transverse shortening of the fibers or in the direction of their longitudinal fibrillation), it is necessary to control the paper-forming properties of the fibrous mass and the physical and mechanical properties of the castings.
The publication presents an analysis of the influence of the paper-forming properties of the fibrous mass on the quality of its refining, it is advisable to find the dependence of these indicators on the rheological features of the fibrous suspension flow in the refining zone, that is, to determine the relationship of the paper-forming properties of the fibrous mass with the dynamic viscosity coefficient during the flow of the fibrous suspension in the refining zone.
