Basic Polymer Rheology, as related to Extrusion Coating Machinery
LDPE remains the classic material of choice for many Extrusion Coating Applications, due to excellent processing and end-use performance reasons. High shear extrusion screws are desirable, actually promoting oxidation of the melt for improved adhesion to substrates. T-shaped flat die technology, with internal deckling, has emerged as the premium technology to handle monolayer and multilayer ext...
متن کاملThe in uence of viscoelastic rheology on blade coating as revealed bynumerical methods 1
The innuence of an elastic component of the rheological properties of the coating suspension on the coating ow in the blade coating process was investigated by numerical methods. The Giesekus model was used as the constitutive equation for the coating uid (coating colour). The system of time-dependent partial diierential equations was solved numerically by dis-cretising the solution with nite d...
متن کاملTheoretical and Numerical Modeling of Coating Flow on Simple and Complex Substrates including Rheology, Drying and Marangoni Effects
We discuss the development of a comprehensive mathematical and numerical model for thin-layer flow of complex liquids on solid surfaces. The model includes physical and surface chemistry effects and allows direct prediction of the flow as it evolves in time, until the liquid has solidified. We pay particular attention to the substrate shape and wetting properties as well as viscosity dependence...
متن کاملRheology
researchers write. So, during the dry season, the entire population is represented by developing eggs that incubate for 8–9 months, before hatching synchronously at the beginning of the following rainy season. “Remarkably, this chameleon spends more of its short annual life cycle inside the egg than outside it,” they report. The authors reviewed data on the life cycle of more than 1,700 tetrapo...
متن کاملBlood rheology and aging
The flow properties of blood play significant roles in tissue perfusion by contributing to hydrodynamic resistance in blood vessels. These properties are influenced by pathophysiological processes, thereby increasing the clinical relevance of blood rheology information. There is well-established clinical evidence for impaired blood fluidity in humans of advanced age, including enhanced plasma a...
