塑料单螺杆排气挤出机的冒料问题探讨

A Study on the Problem of Venting-up-of Plastics Single Screw Vented Extruders

根据实验与应用研究,着重从排气挤出机的设计和操作工艺两个方面论述了排气口冒料产生的原因、克服措施与如何建立最大泵送压力的问题,并简述了本研究第一台样机的性能特点。

With the emphasis on design and operation aspects of two-stage single screw vented extruders,the cause of the occuring of probable measure to cope with the problem of venting-up is discussed in the paper. The discussion also covers the problem of how to set up the maximum-pumpout presure, Based on the study, on experimental machine was manufactured. The performance of the machine is briefly described.
