摘要： Disclosed is a cylinder heating device of a conduit forming system using waste synthetic resin, in which a pipe type unit heater is used rather than a bend type heater to prevent heat loss during heat transfer to a cylinder so that waste synthetic resin in the first and second space parts in the cylinder is melted within a short time as well as the quality of a formed conduit is improved.

摘要： A method for manufacturing a carbon fiber is provided which involves: (1) immersing a carbon fiber composite material (CFC) in an acidic aqueous solution to elute at least a part of a resin component of the CFC, to thereby obtain a substantially fibrous product; and (2) immersing the substantially fibrous product obtained in step (1) in an alkaline aqueous solution to elute at least a part of a resin component of the substantially fibrous product, to thereby obtain a fibrous product. A method for manufacturing a carbon fiber reinforced resin composition is provided which involves manufacturing a carbon fiber by the above method and manufacturing a carbon fiber reinforced resin composition using the resulting carbon fiber. Using these methods, it is possible to recover and recycle a carbon fiber from a carbon fiber composite material (CFC) at a low cost without deteriorating the carbon fiber.

摘要： A system comprising: (1) a grinding unit configured to receive and grind recycled PET bottles into a group of polymer flakes comprising up to about ten percent colored polymer flakes and balance substantially clear polymer flakes; (2) a washing unit configured to wash the group of polymer flakes; and (3) an extruder configured to extrude material in a plurality of different extrusion streams. The extruder may be further configured to: (1) receive a concentrate-polymer mixture comprising a mixture of the polymer flakes and a color concentrate; (2) melt the concentrate-polymer mixture to produce a polymer melt; (3) reduce a pressure within the extruder; and (4) pass the polymer melt through the extruder so that the polymer melt is divided into the plurality of extrusion streams. The system may then filter the polymer melt through at least one filter and form the polymer melt into bulked continuous carpet filament.

摘要： The invention relates to a method and a processing plant (1) for plastic material, for the recycling thereof. To this end, the processing plant (1) comprises a feed device (4), a processing unit (2) having a comminuting device (5) and a conveying device (6) adjoining the comminuting device (5), and an extrusion device (3) having an extruder screw (21). During its conveying movement along a first conveying section (9) toward a transfer region (8) by means of the conveying device (6), the comminuted plastic material is heated to a transfer temperature with a mean temperature value, which falls into the range of the softening temperature of the plastic material. In the transfer region (8), the comminuted plastic material is transferred to the extrusion device (3).

摘要： Systems for manufacturing bulked continuous carpet filament from polymer, where the systems are configured for: (1) melting polymer (e.g., derived from post-consumer PET bottles) to create a first single stream of polymer melt; (2) separating the first single stream of polymer melt into multiple streams of polymer melt; (3) exposing the multiple streams of polymer melt to a pressure of between about 0 millibars and about 5 millibars; (4) allowing the multiple streams of polymer melt to fall into a receiving section of a melt processing unit; (5) recombining the multiple streams of polymer melt into a second single stream of polymer melt; and (6) providing the second single stream of polymer melt to one or more spinning machines that are configured to form the second single stream of polymer melt into bulked continuous carpet filament.
