纳米ZrO2粉末的悬浮流变特性与注浆成型研究

Based on the relative theory of polymer rheology and hydromechanics, the mechanisms of wall slip and surface tension on micro channels are analyzed thoroughly, and two kinds of wall slip boundary conditions are imported according to different mechanisms.

依据聚合物流变学及流体力学的相关理论，深入分析了微小通道中壁面滑移和表面张力的作用机理，并根据不同的作用机理，确定了两种滑移边界条件。

The following main achievements were yielded: ( 1) Based on process characteristics of gas-assisted full slip extrusion molding and the theories of rheology and hydrokinetics etc., under reasonable assumption, full three dimension steady isothermal viscoelastic theoretical model of describing gas-assisted extrusion molding process is established.

针对气辅完全滑移挤出成型过程的特点，基于流变学和流体动力学理论，经合理假设，建立了描述气辅完全滑移挤出成型过程的全三维稳态等温粘弹性理论数学模型。
