Methods of measuring the rheological properties of compounds for extrusion
Tóm tắt
A classification is given for methods of measuring the rheological properties of ceramic compounds for extrusion. Depending on the magnitude of the shear stresses under which the testing is performed, it is proposed that the methods of investigation be divided into structural-mechanical and rheological. The most informative methods as well as the structural-mechanical and rheological parameters obtained with these measurements are described. Recommendations are given for using each method for scientific investigations and for checking the parameters of the molding compounds in the production of extruded ceramic articles.
