中文摘要:

      纸浆纤维悬浮液是以纤维为固相的非均相混合物,属多相流体。屈服应力作为纸浆纤维悬浮液最重要的流变参数之一,在制浆造纸高效、节能、低耗的生产操作技术及装备的优化设计方面扮演着重要的角色。本文就纸浆纤维悬浮液屈服应力的产生及其影响因素、测量方法及装置进行归纳和总结；在此基础上,阐述了纸浆纤维悬浮液的屈服应力在制浆造纸生产中的应用,并对纸浆纤维悬浮液屈服应力的进一步研究及其在造纸工业相关领域的发展应用提出了思路。

Abstract:

      Pulp fiber suspension is multiphase heterogeneous mixture, within which fibers are considered as solid phase. Yield stress is one of most important rheological properties of pulp fiber suspension which plays an important role in design and effective operation of the equipment in pulp and paper industry. This paper reviewed past studies on the generation and measurements of yield stress of pulp fiber suspension and its impact factors, moreover, details about the applications of yield stress of pulp fiber suspension in pulp and paper industry were presented as well. In addition, further studies and applications of yield stress of pulp fiber suspension in relevant fields of papermaking industry were discussed.
