导热油传热技术在塑料加工中的应用

Application of Heat Transfer Technology with Heat-conducting Oil as Medium in Plastic Processing

分析了聚合物塑化挤出成型过程中外部热量输入的技术要求,研究了挤出成型过程中出料螺杆和孔板加热的导热油传热设备的结构特点和温度自动控制系统的要求。

The technical requirements of external heat input during the plasticizing extrusion molding process of polymer were analyzed. For the heating of the outlet screw and orifice-plate during the extrusion molding, the structural characteristics of heat transfer equipment with heat-conducting oil as medium were studied, and the requirements of the automatic control system for temperature were also investigated.
