screen changer for recycling processes applications in plast
With the rising price of plastic raw materials, extrusion companies to reduce production costs and increase profits, artificially increasing the proportion of recycled material. Add a proportion of some agricultural plastic products recycled material up to 80% to 90%. Changer is one of the important factors affecting the quality of the plastics recycling materials. Extensive use of recycled materials has greatly promoted the development of the screen changer for recycling processes and changer application brings a broad market, and the changers proposed new requirements.
Plastic extrusion process, plastic melt after prolonged plastics will produce some decomposition, while the raw material itself contains some impurities. The presence of these impurities affect not only product quality, but also affect the production of continuity and stability. Changer disposed between the screw head and extruder head, used to filter out impurities and foreign plastic melt to obtain pure melt.
