Rheology and Storage Tests of Dead Sea Shampoo

open access: yesApplied Rheology, 2004
Changes in the rheological properties of hair shampoo samples differing in the content of Dead Sea (DS) salt were studied. The rheological properties were tested during a 28-day storage period at three different storage temperatures (cold, room ...

Modeling the kinetics nonenzymatic browning reactions and rheological behavior in the termal process of fruit juices and pulps

open access: yesScientia Agropecuaria, 2010
In the manufacture of fruit juices and pulps, is of paramount importance to refer to non-enzymatic browning and rheological behavior. The non-enzymatic browning is a phenomenon of darkening of a purely chemical (Braverman, 1980), is characterized by the ...

The Influence of Continuous Shear, Shear History and Relaxation on the Rheological Behavior of Sio2/Glycerine Suspensions

open access: yesApplied Rheology, 2015
Suspensions of SiO2 microspheres in glycerine exhibit drastic shear-thickening behavior under steady shear and dynamic oscillatory shear test. The rheological behavior of suspensions agrees with the modified Cox-Merz rules as the dynamic oscillatory ...

Rheological Behavior of Fresh Cement Pastes

open access: yesFluids, 2018
Rheology of a concrete is mainly controlled by the rheological behavior of its cement paste. This is the main practical reason for the extensive research activity observed during 70 years in this research subfield. In this brief review, some areas of the

Rheological Characterization and Molecular Modeling of Poly(n-butyl acrylate)

open access: yesApplied Rheology, 2010
We propose an exhaustive experimental characterization of a series of poly(n-butyl acrylate) samples that were synthesized by controlled radical polymerization and have different molecular weights.

Capillary non-Newtonian seepage model of unvulcanized rubber expressed by the four-parameter rheological flow

open access: yesPolymer Testing, 2023
Micro-bubbles and pores in a tire, generated by the seepage process of rubber into steel cord, seriously degrade the safety of the tire in use. However, unclear seepage behavior of unvulcanized rubber while flowing into the interstice of steel cord makes

Rheological properties of alumina injection feedstocks

open access: yesMaterials Research, 2005
The rheological behavior of alumina molding feedstocks containing polyethylene glycol (PEG), polyvinylbutyral (PVB) and stearic acid (SA) and having different powder loads were analyzed using a capillary rheometer.

Mathematical Model for Establishing the Time-Dependent Behavior of Rocks by the Gradient Method

open access: yesApplied Sciences, 2022
In the underground activity domain, most problems related to mining pressure and mining stability need to be solved by taking into account the time behavior of rocks through an approach of the interaction amidst the rock massif, support system, time ...

Investigation on the tensile rheological behavior of pa6 film based on fractional order model

open access: yesMaterials Research Express, 2023
This paper presents the research results on the rheological behavior of Polyamide 6 (PA6) film during uniaxial stretching. The creep and relaxation tests of PA6 films were conducted on dynamic mechanical analysis (DMA) tester under uniaxial tensile ...
