DEVICE FOR EXAMINATION OF RHEOLOGICAL PROPERTIES OF MATERIAL IN SPINNERET MODEL

摘要

FIELD: equipment for pressing of biopolymers, applicable for measurement of rheological parameters of pressed material. SUBSTANCE: the device has a cylindrical base with a larger strain- gauge ring installed in it, a support positioned on the cylindrical base with a smaller strain-gauge ring installed on it, the support carries a spinneret with stain-gauge transducers, compression chamber formed by a cylinder having a tight contact with the spinneret, support and plunger, he plunger is provided with a rod with a piston of a different length and diameter fitted on it. EFFECT: possibility of examination of the process of flow of pressed material in the boundary layers of the spinneret at high velocities of shear. 1 dwg
