    摘要: 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) farther 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).

    摘要: A static mixer head that provides not only distributive mixing, but also dispersive mixing. Distributive mixing is accomplished by providing a series of baffles along the length of the mixing tube, each baffle being angled relative to the previous baffle. Dispersive mixing is accomplished by utilizing baffles that define a converging pathway for the mixing materials. The converging pathway promotes elongation and corresponding dispersion of the mixing materials. In one embodiment, the baffles are teardrop-shaped, and are arranged so that multiple baffles are generally parallel and adjacent to one another. Preferably, the baffles are oriented such that the mixing materials flow from the small tail portion of the baffles toward the larger head portion of the baffles, thereby encountering a gradual compressive force and corresponding elongation.
