This Online course contains the
Introduction Capillary Rheology & Rheometer:
- Introducing a Capillary Rheometer & Shear Viscosity Measurements
- Bagley CorrectionThe Rosand high-pressure capillary rheometer systems enables controlled extrusion (by volumetric flow) of a sample through a high-precision die of known dimensions. This enables characterizing material flow properties, typically under conditions of high force (or pressure) and/or high shear rate. Bagley Correction
- Extensional Viscosity
- Typical Capillary Corrections
- Case Studies Showing Uses of Capillary Rheology
- Polymer and Non-Polymer Capillary Applications
- Hardware Options
Software Test Modes:
- Software Overview and Constant Shear Rate Test
- Melt Fracture Test
- Flow / No Flow Test & StressStress is defined as a level of force applied on a sample with a well-defined cross section. (Stress = force/area). Samples having a circular or rectangular cross section can be compressed or stretched. Elastic materials like rubber can be stretched up to 5 to 10 times their original length.StressRelaxationWhen a constant strain is applied to a rubber compound, the force necessary to maintain that strain is not constant but decreases with time; this behavior is known as stress relaxation. The process responsible for stress relaxation can be physical or chemical, and under normal conditions, both will occur at the same time. Relaxation
- Degradation Testing
- Manual Test & Low Level Script
