摘要
介绍了振动力场作用下高分子材料动态挤出成型、动态注射成型以及动态混炼成型的技术及装备,简要阐述了动态挤出中动态固体输送、动态熔融塑化、动态熔体输送过程的机理及实验研究成果,分析了脉动压力对注射过程的影响以及动态混炼过程中强制混炼、强制分散的原理,对各种动态成型技术辅以相应的制品性能测试。研究结果表明振动力场的引入在产量相同并保证甚至改善制品综合性能的同时,可有效缩短成型历程,降低功率消耗,因此高分子材料动态成型加工方法是一种新型的低能耗成型加工技术。
The technologies and equipments of the dynamic extrusion, dynamic injection and dynamic mixing implemented by the application of vibration to the polymer processings were introduced. The mechanisms of the dynamic solid conveying, dynamic melting and dynamic melt conveying of the dynamic extrusion were elaborated. The effects of the pulsating pressure on the injection process and the principles of enhanced mixing during dynamic mixing were analyzed. Testing results of the performances of the products manufactured by the above dynamic processing technologies were also presented. The research results indicate that the introduction of vibration force field can shorten the processing efficiently and reduce energy consumption, while keeping the same output and guaranteeing or even improving the integrated properties of products.
