抄録

An expedient experimental method has been proposed to evaluate the kneading state and process based on measuring of the flow and dispersion characteristics for the kneaded mass. The talc powder containing 20 mass％ of vaseline binder was adopted as a common testing material. The comprehensive change in the flow characteristics of kneaded mass with operating time was measured by a simple extruding test using a capillary rheometer. Furthermore, proper amount of blue pigment powder was added to trace the dispersing process and its attainable state.<br>Kneading characteristic curves were obtained based on both apparent viscosity and relative lightness value of the kneaded mass samples. It has been shown that the simple direct extrusion test and the tracer technique including the combination of the testing materials were recommendable convenient methods as the first step to evaluate the complicated kneading phenomena and processes. As a case study, characterization of the different types of kneader has been demonstrated by using the index K_IDX.
