    • A screw extruder (10) having a barrel (18) which has a bore (26) defining an inner surface (44) and one or more extruder screws (28), positioned within the bore (26). The extruder screw or screws (28) include a central shaft (34) and one or more screw flights (30). The extruder screw or screws (28) further including one or more dispersive mixing elements (204, 234, 308, 406, 508, 558), which interact with the inner surface of the barrel (44) to form one or more progressively narrowing passages (46) through which material is forced into multiple regions of high elongational and shear stress (480, 120, 214, 310, 410, 510, 564). A second preferred embodiment is a screw extruder (10) having a barrel (18) having a bore (26) defining an inner surface (44) and one or more extruder screws (600, 701), positioned within the bore (26). The extruder screw or screws (600, 701) include a central shaft (602, 706) and a number of dispersive mixing elements (604, 608, 714), which are configured and positioned to form a number of progressively narrowing passages (606, 716) through which material is forced into multiple regions of high elongational and shear stress (608, 718).

    • An mixing section (10) for an extrusion screw has an inlet end (12) and an outlet end (90) as well as alternating wiping lands (30) and barrier lands (50). The barrier lands (50) have a greater helix angle than the wiping lands (30). The wiping lands (30) and the barrier lands (50) define inlet channels (34) which narrow toward the outlet end (90) and outlet channels (54) which widen toward the outlet end (90). A helical pattern of mixing channels (60) is cut into the wiping lands (30) and the barrier lands (50). The mixing channels (60) may be oriented generally at approximately right angles to the wiping lands (30) and the barrier lands (50). A portion of the extrudate encounters the inside wall surfaces of the mixing channels (60) and changes direction which improves the mixing of the extrudate.
    • 用于挤出螺杆的混合部分(10)具有入口端(12)和出口端(90)以及交替的擦拭平台(30)和障碍区域(50)。 阻挡平台(50)具有比擦拭平台(30)更大的螺旋角度。 擦拭平台(30)和阻挡平台(50)限定了朝向出口端(90)变窄的入口通道(34)和朝向出口端(90)变宽的出口通道(54)。 混合通道(60)的螺旋图案被切割到擦拭平台(30)和阻挡平台(50)中。 混合通道(60)可以大体上与擦拭平台(30)和阻挡平台(50)成直角定向。 挤出物的一部分遇到混合通道(60)的内壁表面并改变方向,这改善了挤出物的混合。
