Abstract
Disclosed are a system and method tuning PET raw material processing process by employing real time process management and machine learning steps and reactive addition of dosing of homogenizing composition for impregnating chain extenders and compatibilizing agents in thermoplastic resin using the liquid additive as a carrier into the process for modifying material performance. The properties of PET blend are no longer fixed once dry-blending and melting is complete.
Claims20
A system for processing PET raw material or recycled PET material comprising a conventional plastic processing machine comprising a plasticizing cylinder for molten thermoplastic resin and a system for administration of additives characterised in that the system is reactive and adaptive comprising a dynamic PID system comprising a programmable logic controller (PLC) and system of plurality of sensors wherein system of plurality of sensors comprises sensors at a material hopper, a screw, and a dispensing throat of the plastic processing machine.
A method of processing of PET raw material or recycled PET material comprising drying and processing plastic in a conventional plastic processing machine comprising a plasticizing cylinder for molten thermoplastic resin and administration of additives wherein branching and chain length of PET is controlled in the liquid PET using blend of liquid PET chain extenders.
