Description
This unit of competency covers the skills and knowledge required to determine rheology and output of plastics materials from processing equipment.This unit of competency applies to experienced technicians or those in similar roles who are required to apply in-depth knowledge of materials, process, equipment and problem solving in order to perform calculations using the rheological properties of polymers and apply that to their performance in process equipment.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1 Determine flow characteristics of polymer compound
  • 1.1 Calculate and describe shear and shear rates
  • 1.2 Distinguish between Newtonian and non-Newtonian flow
  • 1.3 Identify the characteristics of polymer structures which influence flow
  • 1.4 Identify the relationships between density, temperature and viscosity for polymers
  • 1.5 Identify the flow characteristics of a polymer compound based on its structure and temperature
2 Calculate flow rate of polymer compound
  • 2.1 Use equipment dimensions and data to determine shear rate of polymers through that equipment
  • 2.2 Calculate output from equipment using viscosity curves and shear rate diagrams
  • 2.3 Calculate mean velocity at critical points in a process
  • 2.4 Determine the characteristic curves for the screws and dies in processing equipment, and the resultant operating point for the system
