摘要： A viscoelastic extrusion process (VEEP) for biopolymers such as polylactic acid is provided. The VEEP process removes many processing and performance limitations of PLA as well as creates performance sufficient to produce durable “nonbiodegradable” products as a direct replacement for PVC and other petrochemical profile and sheet extrusion applications. The VEEP process also retains a high degree of crystallinity within the PLA for increasing toughness and to lower its biodegradability. The invention also includes an integral process wherein rheology is highly modified to allow profile extrusion and higher melt strength wherein processing is lower than the melting point of the primary biopolymer and below the browning points of the natural fibers in the biopolymers viscoelastic state.

摘要： A polymeric composite useful for producing large shaped articles such as railroad crossties comprises a filler component having minimal reinforcing/structural characteristics; and a polymer blend including at least one polymeric stiffening component, at least one polymeric density component, and at least one polymeric flexibility component. The polymer blend can include post-consumer recycled thermoplastic polymers. To produce the composite, a multistage extruder brings a blend of polymer and filler materials to an extrudable threshold without completely liquefying the polymer blend. The extruded blend is cooled within a mold to form a shaped article such as a recycled composite crosstie. Exemplary recycled composite mixtures may include composite polymer materials, such as, polypropylene, High Density Polyethylene (HDPE), High Molecular Weight Polyethylene (HMW), Low Density Polyethylene (LDPE), ABS, Ethylene Vinyl Acetate (EVA), Linear Low Density Polyethylene (LLDPE), and combinations of these polymers. The filler may include talc, fly ash, potash, and combinations of these or other mineral powder products.

摘要： The present invention relates to a pellet-type non-crosslinked polypropylene foam having a melting point of 125 to 140null, and a process and device for producing said foam. Since the pellet-type foams of non-crosslinked polypropylene of the present invention has a lower melting point and a closed cell content of 80% or more, it is advantageous to mold such foams. The present invention also relates to an article molded from the above pellet-type non-crosslinked polypropylene foams.

摘要： A cool-dissolving apparatus for producing a solution from a mixture of polymer and solvent includes a double-structure pipe which is constructed of a cylinder and a jacket surrounding the cylinder. A mixture is fed in the cylinder, and a cooling medium flows in a space between the cylinder and the jacket oppositely to the mixture in the cylinder such that polymer dissolves to the solvent. The obtained solution is supplied in a heat-dissolving apparatus including a pipe for feeding the solution. In the heat-dissolving apparatus, the pipe extends horizontally or upwards in a feeding direction of the solution.

摘要： The invention is a method for operating an extruder temperature controller. The method can include sensing an actual screw speed for an extruder screw in an extruder barrel. The extruder barrel has at least one heat exchange means. The method can then involve indexing and storing a plurality of screw speeds. Each of the stored screw speeds corresponds to a temperature reset value. Comparing the actual screw speed with each of the stored screw speeds can then be performed. Selecting one of the stored screw speeds can then occur. The selected screw speed is a member of the plurality of stored screw speeds having a value most arithmetically equivalent to the actual screw speed. The step of selecting retrieves the temperature reset value corresponding to the selected, stored screw speed. Generating a control output driver signal to the heat exchange means can occur. The control output driver signal is responsive to the retrieved temperature reset value. The invention includes delaying a control alarm for a predetermined time when generating a control output driver signal to the heat exchange means is at or near maximum capacity.
