DESIGN AND DEVELOPMENT OF A SMALL SCALE MACHINE FOR RECYCLING DISCARDED THERMOPLASTIC INTO FIBER FOR INSULATION

摘要

The invention describes a small-scale thermoplastic recycling apparatus and method in producing fiber strands used as an alternative for insulation. The claimed invention is a small-scale recycling thermoplastic apparatus with two components, mainly, the extruder and the spinner. The extruder accepts and melts the shredded thermoplastic to produce a continuous flow of molten plastic called extrudate. The extrudate is fed to the spinner through a nozzle. Using centrifugal force, molten plastic pass through perforated holes of the spinner producing the individual fiber strands. The said thermoplastic recycling apparatus is capable of recycling polypropylene (PP) plastic, PET plastic, HDPE plastics and LDPE plastics. The produced thermoplastic fiber strands may be used as an alternative material for insulation such as low thermal insulation, sound proffing and packkaging.
