摘要:
The present disclosure relates to a process for recycling of plastic waste comprising: segregating plastic waste collected from various sources followed by cleaning of the segregated plastic waste to obtain segregated cleaned waste; grinding of the segregated cleaned waste to obtain grinded waste; introducing the grinded waste into an extrusion line having a venting extruder component as part of the extrusion line, to obtain molten plastic; and removing the impurities by vacuum venting of the molten plastic to obtained recycled plastic free from impurities.The present disclosure further relates to various articles like Industrial Post Recycled (IPR) plastic tubes, blow moulded bottles, pallates, manufactured from the recycled plastic waste.

摘要:
A system and a method for the production, filling, packaging and/or transport of beverages in beverage containers. The system components are coupled physically and by a common control unit. Furthermore the system components are coupled at least partially energetically. The system components form mutually coupled energy conversion units, energy storage units and/or energy consumption units. The system components are provided with energy from one common energy generating device, which supplies mechanical operating power (wave energy) and/or electrical energy and/or thermal energy to the system components.
摘要:
An apparatus for the conditioning of plastics material pre-forms with a tempering space for receiving a plurality of plastics material pre-forms, with a supply device a removal device, and a conveying device which conveys the plastics material pre-forms from the supply device to the removal device in such a way that each plastics material pre-form remains in the tempering space for a preset duration of the dwell period. The temperature of the plastics material pre-forms upon leaving the removal device is substantially constant irrespective of a duration of the dwell period of the plastics material pre-forms in the tempering space and the conveying device is designed in such a way that each plastics material perform remains in the tempering space for a period of time of at least five minutes.
摘要:
An apparatus for shaping plastic preforms into plastic containers, including a plurality of blow moulding stations which each have a cavity in which the plastic preforms can be shaped into plastic containers. The blow moulding stations are arranged on a movable carrier and each have a stretching rod which stretches the plastic containers in their longitudinal direction by a movement in a stretching direction. A fluid-actuated drive device is provided for driving the stretching rod in the stretching direction. The apparatus includes a guide cam which is arranged in a stationary manner and by means of which the stretching rod can be moved counter to the stretching direction as a function of a movement of the blow moulding station. At least one portion of the guide cam is adjustable and, for example, by virtue of this adjustment a dependency of the movement of the stretching rod on the movement of the blow moulding station can be varied.
摘要:
A blow molding machine with air conditioning that while minimizing the introduction rate of outside air, realizes maintaining of constant temperature in not only a plant building but also the interior of a blow molding machine and production of a bottle as a final configuration with stability in its measurement value. The blow molding machine with air conditioning is constructed so that air for use in biaxially stretching blow molding together with hot air of heating zone (1) and internal air of a plant building is suctioned by means of suction chamber (4), filtered by means of primary filter (6) and secondary filter (7) into clean air, brought into heat exchange with primary cooling coil (8), fed under pressure by air blower (10) and released through low-temperature duct (12) into the interior of the plant building. Further, the construction is made so that housing (3) on its side face is provided with vent (3a) so as to allow reflux of the clean air released into the interior of the plant building and flow into the heating zone (1) and blow zone (2).
