ABOUT THE TECHNOLOGY OF OBTAINING POLYMER SEMI-FINISHED PRODUCTS AND FINISHED PRODUCTS FROM USED PLASTIC PACKAGING
Over the past decades, plastic products, due to their technical characteristics and relative cheapness, have become popular in almost all areas of production, displacing more expensive raw materials - wood, glass, metal, stone. Polymer materials are widely used in all areas of human activity. Most products made of plastic are considered non-degradable. Therefore, the issue of recycling is relevant. The analysis of the applied technology for the processing of used plastic packaging of food products is given. The description of the characteristics and basic properties of plastic masses is given. Schemes and features of equipment for shredding plastic packaging are given, advantages and disadvantages of methods for shredding polymer waste are noted. A design and technological scheme of the installation for continuous power grinding of various types of plastic packaging and containers is proposed. The technological scheme and the machine-hardware scheme of the line for the production of polymer semi-finished products and finished products have been developed. Possible options for the secondary use of crushed plastic waste for the manufacture of various types of technical products are considered.
