在线流变仪的研究进展与应用

Development and Application of On-line Rheometer

通过对聚合物流变性能的测试,可以指导并优化聚合物加工工艺、提高产品质量,因此流变测试技术在实际加工生产中具有重要意义。流变测量仪器根据安装方式主要分为在线型和非在线型。由于非在线流变仪的局限性,其所测试结果已经不能满足实际加工的需求,所以在线流变仪得到了越来越广泛的应用。文章主要综述了在线流变仪的研究进展,包括在线流变仪的定义、分类、结构及其应用与发展。

By the rheological measurement, the polymer processing can be optimized and the quality of the end-products can be improved as well, so rheological parameters play a very important role in the polymer processing industries. The rheometers generally fall into two categories according to the location mode： not on-line and on-line. On the limitations of not on-line rheometer,the rheological parameters gain from it can not meet the needs of practice, so the on-line rheometer has gotten more and more application. The development of in-line and on-line rheometer,including the definition, classification configurations of the on-line rheometer is reviewed,and the applications of the on-line rheometer are also introduced.
