Study on the precision co-extrusion technology for PET recycling

The recycling of polyethylene terephthalate (PET) i s of significance to the construction of ecological environment, so the recycling technology and relevant equipment has a broad prospect of application. The disadvanta ge of traditional PET recycling process is analyzed in th is paper, the PET precision co-extrusion process is proposed, and the co-extrusion device is designed. Experimental rshow that the co-extrusion technology can me et the requirements of large-scale, continuous, precise an d high-quality melting and extrusion process of PET recycling.
