Rheological Properties of Slurry of Foam Cushion Packaging Based on Fiber and Starch
Abstract:
The rheological behavior of slurry of foam cushion packaging based on fiber and starch was analyzed using digital viscosity meter. Meanwhile the response relationship of viscosity to time, shear rate to shear stress, and viscosity to temperature were also measured. The results showed that the slurry is a kind of non-newtonian fluid with the character of shear thinning. With the increasing of shear rate, apparent viscosity of system keeps in decreasing till the steady state finally. With temperature rising, plastic viscosity and yield strength of slurry will be smaller susceptibly. At last, Casson-Model was chose for the matching of plastic viscosity and yield strength.
