The process design of EPDM/PP blend material for annual output 3000 tons
Abstract: This topic is the annual output of 3000 tons of EPDM/PP blend material workshop process design, the main production of thermoplastic elastomer of low hardness. This design adopts the technological process is to use the double screw extrusion machine adopts dynamic vulcanization method. Design content mainly includes the formula design and material selection, material balance, energy balance, process equipment selection and calculation of the workshop layout design and process design, design the result mainly design specifications and the corresponding drawings, drawings including floor plan and elevation. Innovation point of this design is to EPDM and polypropylene as the main raw material, stearic acid as activator, sulfur as curing agent, promoter DM as vulcanization accelerator, the preparation of silica as reinforcing agent is of low hardness EPDM/PP blend material, simple technological process, product high purity, is the EPDM/PP blend material production of a high yield, high quality and low cost effective way.
