Stretching of Viscoelastic Liquids M. M. DENN and G. MARRUCCI.Analyses of stretching of a viscoelastic liquid have been interpreted os showing that there is o maximum stretch rate to which the material can be subjected, and several physical phenomena hove been explained on this basis.

Description: Previously a PU-2C spray system was specified. Now, the mobilization cost are extremely low. All needed, is a crew, scaf-folding and CZH material. Any hook, shape or diameter pipe can easily be protected.
The coating bead flow and operability window for Newtonian coating liquids are theoretically and experimentally investigated in the slot coating process, with a focus on the shape of the upstream meniscus and contact angles. From the flow visualisation in the coating bead region, the contact... Operability windows in viscoelastic slot coating... —… The viscoelastic-capillary model to predict approximately coating windows for the stable operations of viscoelastic coating liquids is derived using a lubrication approximation in slot coating processes.
