1. Process flow: the composite regeneration treatment technology is more complex. Firstly, it is necessary to sort the waste plastics according to the resin varieties, and then add appropriate fillers according to the performance requirements of the recycled products. Then, the new resin materials or modifiers are mixed again, and then processed into the required products by melting and mixing. The general technological process of composite regeneration: collection → pretreatment → crushing → screening → cleaning → drying → mixing → melting → molding → post-treatment → recycled products 2. Technical points: because of the various sources of waste, it is not suitable to use the common plastic processing equipment for direct processing, so the composite regeneration technology has the following requirements for equipment and raw materials: (1) The existing plastic processing equipment is reformed to meet the needs of complex material composition. (2) Use special recycling and processing equipment for waste plastics. (3) The hybrid waste plastics were chemically modified. (4) The combination of waste plastics and new materials is adopted, with waste as the core layer and covered by new materials. (5) Waste plastics are used as fillers and added into other plastics or non plastics. (6) The masterbatch was made from waste plastics and cheap fillers.
