摘要： The invention relates to a method for producing a polycondensate melt from a primary material and a secondary material from materials of substantially the same type. A first partial melt stream (I) of the primary material and a second partial melt stream (II) of the secondary material are provided, and a measured value of the intrinsic viscosity of both partial melt streams (I, II) is determined, and a difference value is calculated from said measured values. Based on said difference value, the intrinsic viscosity of the second partial melt stream (II) is increased, reduced or maintained unchangedly by means of a first melt treatment device (8). Subsequently, the two partial melt streams (I, II) are combined into a common melt stream.

摘要： In a method and an apparatus for increasing the intrinsic viscosity of a polycondensate melt at negative pressure, the melt enters a chamber, in which a negative pressure of less than 20 mbar prevails, through a perforated plate or a screen having openings with a diameter of less than 0.5 mm. The melt passes through this chamber in free fall in thin threads and remains in a reservoir beneath the chamber for at least one minute. The melt is moved constantly in the reservoir, and discharged from the reservoir, by a helical mixing and discharge part.

摘要： A device for processing thermoplastic plastic includes a storage container for receiving pieces of plastic particles or a conveying line for conveying the pieces of plastic particles, and a conveying screw following the storage container/the conveying line at a transfer opening. The device also includes an extruder following the conveying screw and an air outlet arranged opposite the transfer opening and directed at this opening. In a method for operating the device, an air stream is aligned with the transfer opening. The strength and/or the direction of the air stream is adjusted or controlled as a function of a load on the extruder.

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).
