Rheological Behavior of Titanium Dioxide Suspensions

Journal of Colloid and Interface Science, 2001
The rheological properties of titanium dioxide dispersed in water are measured over a wide range of powder concentrations, temperatures, and pH values. The value of intrinsic viscosity of titanium dioxide measured with an Ubbelohde capillary viscometer is 3.55, which is useful for determining the shape and aggregation property of the particles.

Rheological Behavior of Thermoplastic Vulcanizates

Macromolecular Symposia, 2012
AbstractSummary: Dynamic and steady shear rheological properties of dynamically vulcanized iPP/EPDM blends were investigated. Two different curing systems based on sulfur or phenolic resin were applied on iPP/EPDM blends. The use of phenolic resin system allows producing materials with lower viscosity at higher rubber content in comparison with sulfur ...

RHEOLOGICAL BEHAVIOR OF BENTONITE SUSPENSIONS

Petroleum Science and Technology, 2000
ABSTRACT The objective of this research is to investigate the concentration effect on the rheological properties of different bentonite suspensions. Experiments were performed with different bentonite type and concentrations and the results were evaluated by different rheological models (Bingham plastic, Power law, Sisco, Casson, Herchel Bulkley and ...

Rheological Behavior of Glass

1972
The viscosity of glass receives much attention in both academic and manufacturing circles of endeavor. It is a property that is very sensitive to composition differences and hence helps the theoretical scientist understand glass structure and, at the same time, gives the manufacturing team a property suitable for quality control.

Rheological behavior of oligomeric ionomers

Journal of Rheology, 2009
The rheological behavior of the alkali metal salts of oligomeric sulfonated polystyrene (PS) ionomers was characterized using dynamic and steady shear measurements. The starting PS had a weight average molecular weight of 4000g∕mol and a narrow molecular weight distribution (1.06).

Rheological Behavior of Polyethersulfone (PES)

International Journal of Polymeric Materials and Polymeric Biomaterials, 1995
Abstract The rheological behavior of Polyethersulfone (PES), was studied using a Shimadzu Universal Materials Testing Machine and an Haake Torque Rheometer. It is found that in an industrially relevant range of shear rate and temperature PES was highly non-Newtonian.

Rheological behavior of polymer blends

Journal of Applied Polymer Science, 1984
AbstractSteady and oscillatory shearing flow properties of compatible and incompatible polymer blend systems were measured, using a cone‐and‐plate rheometer. The compatible blend systems investigated are blends of two low‐density polyethylenes (LDPE) having different values of molecular weight and blends of poly(methyl methacrylate) (PMMA) with poly ...

Rheological behavior of plasticized polyaniline

Journal of Applied Polymer Science, 1996
In this article, rheological properties of polyaniline (PANI) doped with diisooctyl phosphate (DIOHP) are described. Rheological properties of this material depend strongly on the content of the dopant. For low concentrations, the material is rather stiff but becomes a Bingham or St. Venant body for higher contents of the dopant. Rheological parameters

Rheological Behavior of Polyacrylamide Solution

Journal of Polymer Engineering, 1999
The effect of temperature and concentration on the rheological behavior of polyacrylamide solutions was studied in the temperature range of 20-50°C and the concentration range of 0.2-0.5 wt%. It was found that the viscosity of a polyacrylamide solution decreased with increasing temperature.

Rheological Behavior of Food Gels

2013
Rheological studies can provide much useful information on sol-gel and gel-sol transition, as well as on the characteristics of a gel. There are several definitions of what a gel is that are based on either phenomenological and/or molecular criteria. (1953) defined a gel to consist of polymeric molecules cross-linked to form a tangled interconnected ...
