摘要:

高分子聚合物(例如橡胶、塑料)因自身导热性差和黏性耗散明显,在挤出成型过程中温升十分显著。温度过高可能会增加聚合物热历程、高温氧化断链、破坏材料原始性能、增加能耗等,从而影响聚合物制品的成型品质。鉴于此,本文分析了聚合物挤出过程温升的产生原因,综述了国内外学者从机筒冷却装置、温控系统、螺杆结构优化等方向为低温挤出技术做出的贡献,以及在能耗管理方面的举措,最后展望了低温挤出技术的未来发展趋势。

关键词: 低温挤出, 螺杆结构, 冷却装置, 温度控制, 能耗管理

Abstract:

Polymer materials such as rubber and plastic exhibit poor thermal conductivity and significant viscous dissipation, leading to a significant rise in temperature during the extrusion molding process. Excessive temperatures may increase the thermal history of polymers, cause chain scission due to high⁃temperature oxidation, damage their original properties, and increase energy consumption, thereby affecting the molding quality of polymer products. Based on these issues, this article analyzed the causes of temperature rise during the polymer extrusion process, reviewed the contributions made by domestic and foreign scholars in the direction of low⁃temperature extrusion technology from the aspects of barrel cooling devices, temperature control systems, screw structure optimization, and measures taken in energy consumption management. Finally l the future development trend of low⁃temperature extrusion technology was prospected.

Key words: low-temperature extrusion, screw structure, cooling device, temperature control, energy consumption management
