RHEOMETRY OF CONCENTRATED CERAMIC SUSPENSIONS - STEPS FROM MEASURED TO RELEVANT DATA. PART 3: ROTATIONAL VISCOMETER WITH PARALLEL PLATES, POWER-LAW MODEL

Popis výsledku v původním jazyce

The knowledge of flow behavior of ceramic suspensions is important condition for control of ceramic wet processing. The flow behavior can be stated by the rheological measurements. The aim of the measurements was to obtain the flow curve and to propose suitable and simple rheological model for the flow behavior description. The power-law is the simplest model mostly used for description of rheological behavior of non-Newtonian fluids. Using this model, the dependence of shear stress tau on shear rate (gamma) over dot can be expressed by the relation: tau = K(gamma) over dot(n), where K is the coefficient of consistency and n stands for the flow behavior index. The two arrangements of rotational viscometer method with parallel plates (discs) were used in rheological measurements for results checking. The procedure of experimental data evaluation from rotational viscometer with parallel plates to obtain parameters K and n is presented.
