摘要： A preparation method of a high-rate foamed polylactic acid (PLA) sheet includes first-stage extrusion, second-stage extrusion, and foamed sheet extrusion. The method requires the following raw materials in parts by mass: 88 to 94 parts of PLA, 1 to 2 parts of a nucleating agent, 2 to 5 parts of a foaming agent, and 2 to 5 parts of an additive. The new method effectively solves the problems of low foaming rate, low strength, and the like in the industrial production using carbon dioxide, and a prepared PLA sheet with high foaming rate and excellent surface performance can be used in the fields of food packaging, disposable fully-degradable lunch boxes, and the like.

摘要： Systems and methods are provided for compounding a thermoplastic melt for molding articles, the melt being reinforced with reinforcing fibers. The thermoplastic material is plasticized with an adhesion promoting agent to obtain an initial melt to which the reinforcing fibers are added. The thermoplastic material forms bonds to bond reception sites on the reinforcing fibers to obtain an intermediate melt to which one or more desired additives, such as a colorant, are then added to obtain the final melt. By forming the intermediate melt without the presence of the one or more desire additives, competition between the one or more desired additives and the thermoplastic material for the bond reception sites is prevented, as is damage to the reinforcing fibers from abrasives in the one or more desired additives. Articles molded with the resulting final melt have improved mechanical properties compared to articles made with prior art methods and systems.

摘要： An extruder screw for a multi-screw extruder, having an intake and metering section. A rotor body has an enlarged diameter relative to the intake and metering section and has a plurality of satellite screws positioned on the outer periphery of the rotor body at least over part of the length thereof. A cone and an adjoining drive zone are formed between the intake and metering section and the rotor body, in which drive zone the satellite screws each engage via a drive pinion in an external toothing on the rotor body or in an internal toothing on a stator ring or in the inner wall of an extruder housing. At least one peripherally closed flow channel is formed, which flow channel extends from an inlet opening on the cone to an outlet opening located downstream of the drive pinions in the direction of flow.
