An Approach in Relating Torque Rheometer and Capillary Viscosity Data of Ceramic/Polymer Mixes

摘要

The. torque, rheomotcr data for ceramic-polymer mixes have been converted to a fundamental rheokxiual unit, i.e., viscosity, usintj tht? model proposed by Goodrich and Porter. The torque rheometer data showed good agreement with the. capillary diitn in the low shear rale range. Also, the flow index values obtained from iliu torque rheomeler and capillary measurements have given satisfactory agreement. It is evident that torque rhe.ome.ter can be usi.'d I'ffedively lo determine the ilow behavior of ceramic/polymer mixes.
