摘要

聚合物加工是决定塑料制品最终结构性能的中心环节，其重要的理论基础是聚合物流变学，研究聚合物流变行为的关键仪器是流变仪. 但现有流变仪大多基于简化的流动模型，与实际复杂加工条件不符，难有效揭示聚合物在复杂应力场/温度场作用下的流变行为. 我们基于前期发明的聚合物管旋转挤出加工技术和装备，研制了新型旋转挤出流变仪，可实现挤出/旋转的不同组合和管内外壁双冷，实施和调控旋转挤出中多种运动模式和应力场及温度场，实时检测挤出/旋转速度、应力、温度场，显示记录有关数据，既可用于研究实际加工复杂条件下聚合物加工流变行为，也可用于制备高性能多功能聚合物微导管. 本文综述了新型旋转挤出流变仪的结构特点和原理及其在流变测试与聚合物微导管制备方面的应用.

Abstract

Polymer processing determines the final structural performance of plastic products. Polymer rheology is one of the most important theoretical basis

and rheometer is the key instrument to study polymer rheology. However

most of the existing rheometers are based on simplified flow models

which are inconsistent with the practical conditions

and difficult to effectively reveal the rheological behavior of polymers under the complex stress/temperature fields in practical processing. Based on self-developed rotation extrusion processing technology and equipment

we have developed a novel rotation-extrusion rheometer

which can realize different combinations of extrusion/rotation and double cooling of the inner and outer walls of the tube; implement and control various motion modes

stress and temperature fields during rotation extrusion; and achieve real-time detection

display and recording of data about extrusion/rotation speed

stress

temperature field. The rotation-extrusion rheometer can be used not only to study the rheological behavior of polymer processing under complex conditions in practical processing

but also to prepare high performance multifunctional polymer tubes. The structural features

principles and application of the novel extrusion-rheometer in rheological testing and preparation of polymer tube are reviewed.
