Polymer rheology training
WebJan 11, 2024 · Rheology can be used to determine how thermally stable a specific material is in relation to a process. In addition, it may be useful to determine the specific process residence time. Figure 6 shows a third example, involving nylon film extrusion. In this process, the material was run a little too hot, and gels were visible in the film. WebThe study uses a combination of fundamental, physical models and machine learning methods to develop new predictive models. The data used in the study includes the measured polymer rheology at various polymer concentrations, molecular weights and types, temperatures, and brine salinity and hardness. Data are first fit to the 4-parameter …
