Název v původním jazyce

Pressure-dependent viscosity of PIM compounds

Popis výsledku v původním jazyce

Computer simulations of the PIM process require precise specifications of their flow behaviour. Although temperature effect on viscosity has been commonly taken into account, the viscosity dependence on pressure is still omitted. A single piston capillary rheometer was modified by addition of a second chamber with a restricting valve (developed at the Polymer Centre, Zlin, Czech Republic), which provides backpressure increasing the pressure in the melted material during the flow through the die. The modified White-Metzner model was employed to simultaneously fit the measured viscosity data and determine the temperature and pressure coefficients for ethylene based binder and its compounds with carbide powder. Both temperature and pressure sensitivity coefficients are largely dependent on the structure of a polymer, which should be taken into account for binder formation development. Increasing the loading level of the powder in the compound diminishes the pressure sensitivity of their f
