    摘要： The present invention provides kneading/extruding equipment capable of stable operation by keeping the pressure of kneaded material before a first-stage gear pump in steady operation (molding) and preventing fluctuation of the pressure of kneaded material before the first-stage gear pump constant from largely affecting the pressure of kneaded material before a latter-stage gear pump at start-up or upon change of production rate, and thus capable of responding to an increase in production rate while securing a high-quality molded product, and an operation control method thereof. The kneading/extruding equipment comprises: a rotational speed feedback control unit for a first gear pump, which feedback-controls the rotational speed of the first gear pump, and a rotational speed feedforward control unit for a second gear pump, which feedforward-controls the rotational speed of the second gear pump.

    摘要： A system for supplying processed material includes a barrel for transporting the processed material, having a chamber and an electrically conductive wall enclosing the chamber. The barrel has a length and an outer surface. Thermal insulation extends along at least a portion of the length and around the outer surface and provides an exterior surface whose contour is uniform and formed without grooves. A coil comprising an electric conductor is encased in an electrical insulating sheath. The coil contacts and encircles the exterior surface in loops forming an induction winding that extends along at least a portion of the length and around the exterior surface in a spiral path. An induction power supply is used for supplying alternating current to the coil at a relatively high frequency.

    摘要： Method and systems for online analysis of a polymeric material within a mixing device are provided. In certain embodiments, the methods and systems subject the polymeric material to Raman spectroscopy analysis. The Raman spectroscopy provides analysis of polymer properties that may include melt index, density, viscosity, molecular weight, molecular weight distribution, weight ratios of different polymers comprising the polymeric material, additive concentrations, crosslinking agent concentrations, scissoring agent concentrations, and combinations thereof. The spectroscopy results can be used to provide process control to adjust operating parameters of the mixing device and/or an associated polymerization process. The mixing device may be an extruder. The methods and systems may also include a processor for evaluating the results of the Raman analysis and automatically adjusting the mixing device and/or polymerization processes.

    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.

    摘要： A novel apparatus has been discovered which is of value in the production of polyurethane foam. This invention relates to a one-pass, on-demand apparatus for producing a controlled, homogeneous blend of the polyol-blowing agent mixture used in the manufacture of polyurethane foam using either a low-boiling point or high-boiling point blowing agent. An apparatus is provided to control the amount of each material in the mixture, ensure homogeneous blending of the two materials after mixing, a pressure control means to maintain blowing agents in their liquid state (where necessary), and a monitoring means which allows rapid verification of the operating status of the entire system.
