摘要
介绍了一种以增强拉伸流动机理提高单螺杆挤出机混合效果的新观点,以及新分散混合元件——CRD混合器,介绍该元件的结构特点、用边界元法(BEM)进行理论分析与模拟仿真的结果,以及国外采用新型混合器的实用螺杆情况。该混合器使物料在高剪切区产生拉伸流动,并使其多次通过高剪切区,可获得良好分散混合效果。
Introduced a new point of view to increase the single screw extruder effect based on the reinforcing elongationat flow mechanism and the new dispersing mixing etement--CRD mixer, Introduced the structure property of the element, adopted the BEM （British Empire Medal）method to carry out the theory analysis and analog simulation results, and the utilization of screw used domestic for new kind of mixer, This mixer can make the material bring elongational flow at the high shearing zone, and passed through the zone for many times to gain the good dispersion mixing result.
