依据聚合物工业对加工过程节能降耗、废旧聚合物循环利用、可再生资源利用的重大需求,笔者在聚合物振动剪切形变加工成型方法和设备的基础上提出和研究了聚合物体积拉伸形变加工成型方法和技术,着重讨论了拉伸形变支配的叶片挤压系统的塑化输运过程、技术特征及混合特性.研究结果表明:这种新技术及其设备与传统螺杆塑化输运技术及其设备相比较,具有加工热机械历程缩短、加工能耗降低、混合混炼效果好、物料适应性广、制品质量高等优异的技术特点,且在聚合物多相多组分复合材料、聚合物/生物质复合材料等物料体系的加工方面具有显著优势.

In order to meet the requirements of reducing processing energy consumption, recycling waste polymers and making use of renewable resources in polymer industry, this paper proposes and investigates a elongation rheol- ogy-based polymer deformation processing method and a corresponding technology based on the vibration-shear de- formation processing method and equipment, focusing on the plasticating and conveying process, technical charac- teristics and mixing characteristics of the vane extruder dominated by tensile deformation. It is found that, as com- pared with the conventional screw plasticating and conveying technology and equipment, the new technology and its equipment show many outstanding advantages, such as shorter thermo-mechanical history, lower energy consump- tion, better mixing effects, wider material adaptability and higher product quality; and that it has a significant ad- vantage in processing material systems, such as multiphase and muhicomponent composites, polymer/biomass com- posites, etc.
