Webnoted above. As a result, capillary rheom-eters are widely used in both research envi-ronments and quality control laboratories. Capillary rheometers are versatile and widely used in the rheological measurement of viscous materials where the die sizes nor-mally range from 0.5 to 2.0 mm. However, capillary rheometers suffer from several lim- WebDec 18, 2024 · Capillary rheometers have been widely used for the rheological measurement of polymer melts. However, when micro capillary dies are used, the results are usually neither accurate nor consistent, even under the same measurement conditions. In this work, theoretical modeling and experimental studies were conducted for a more …

WebOct 14, 2024 · Polymer microfluidics: We developed a multi-sample capillary rheometer that is based on a traditional rheometer but uses approximately 1000 times less material. - Simple fabrication; complex flow and mixing possible. - Multi-rate viscometry (spanning 5 orders in rate and 8 in viscosity). Droplet-based interfacial characterization: - By ...

WebCapillary breakup rheometry is an experimental technique used to assess the extensional rheological response of low viscous fluids. Unlike most shear and extensional … Webcapillary the contraction is abrupt (180°) but the exit area has a conical shape. The true capillary length is 0.2 mm thus it fills the condition that the real length must be below 0.5 mm as stated in earlier study2. The geometry of the zero-length capillary is presented in Fig. 1. Due to the geometry of the capillary it is almost impossible to WebA capillary rheometer is an apparatus designed to measure shear viscosity and other rheological (= flow) properties. Capillary rheometers for plastics are piston-die systems designed to measure viscosity of polymer melts as a function of temperature and rate of … introduction to regression analysis
