Project Description

The purpose of this project is to adapt and develop the polymer extrusion technology based on our initial results supported by the MES grant and on combinations with the fundamental die design principles described in [34]. The constant shear rate die manifold design methodology will be investigated on development of extrusion die design based on discretizing winter manifold design equation considering combined thermal and structural effect, in order to fit the rheology of local polymer melt. In addition feasibility of deploying circuit approach for Cross model and Carreau-Yasuda model will be explored for both rectangular and circular manifold for the local industries and provide optimal design of extrusion dies for the purpose of processing the polyethylene and polypropylene (PP) resins produced in Kazakhstan into valuable products as plastic thin films.
The scope of the project is outlined as follows:
• To investigate rheological properties of sample polymer from Kazakh industries and perform, statistical non-linear regression on the rheological test result
• Design and development of Extrusion Die considering temperature aspect as well as die body optimization based on discretizing winter manifold design equation and coupled thermal & Solid effect.
• Investigating Circuit approach for Cross model and Carreau-Yasuda model.
