“…The same authors pointed out that, in the case of commercial bentonites, it is necessary to complete a rheological characterization of each sample, since their behaviour would depend on the industrial treatments applied before use. Yalçin et al (2002) studied the rheology of suspensions of different types of bentonite in water and found Bingham plastic behaviour for the three tested samples, whereas Öztekin et al (2002) showed that bentonite suspensions presented Bingham behaviour and little thixotropy at low concentrations.…”

Friction Losses in Valves and Fittings for Viscoplastic Fluids

et al. 2008

Data on pressure drop were obtained in stainless steel, sanitary fittings and valves during laminar and turbulent flow of aqueous suspensions of sucrose and bentonite. The rheological properties of these suspensions were determined and the Bingham model provided the best fitting with the experimental data. Friction losses were measured in fully‐ and partially‐open butterfly and plug valves, bends and union. Values of loss coefficients (kf) were calculated and correlated as functions of the classical Reynolds number and the Reynolds number proposed by Govier and Aziz (1972) for viscoplastic fluids. The two‐k method and a new proposed model presented the best adjustments for the Govier and Aziz Reynolds number, and Hedstrom and classical Reynolds numbers, respectively.

“…There are numerous studies on possible relationships between the ZP and the rheological properties of a variety of colloidal suspensions. These include suspension of clays [16,[21][22][23][24], alumina [7,16,25], Ce-ZrO 2 [26], Si 3 N 4 [17], anatase [27], zirconia [16], and cordierite [28]. The issue of the existence-or otherwiseof a relationship between viscosity and ZP has been dealt with in a number of studies [20,26,27,29]; unequivocal conclusions have not been reached.…”

“…In recent years, several works have focused on evaluating the effect of ionic and nonionic polymers [1][2][3] , cationic 4 and anionic 5,6 surfactants and electrolytes 7 on the rheology and stabilization of the bentonite-water system based on measurements of its plastic viscosity, yield strength and zeta potential.…”

Influence of ionic strength on the viscosities and water loss of bentonite suspensions containing polymers

et al. 2007

A study was made of the influence of ionic strength (S) on the apparent (AV) and plastic (PV) viscosities and water loss (WL) of sodium bentonite suspension with polymers. Na-bentonite was dispersed in water (4.86% w/w) of different ionic strengths (S = 0.0, 0.015, 0.030 and 0.045 M) followed by the addition of polymer. Three polymer samples were studied, i.e., low viscosity carboxymethyl cellulose (CMC BV), polyanionic cellulose (PAC), and partially hydrolyzed polyacrylamide (HPAM). The results indicated that the presence of salts and increased salinity greatly influence the apparent and plastic viscosities and water loss of bentonite suspensions with polymer
