(PDF) Rheological Behavior of Polyacrylamide/Laponite Nanoparticle Suspensions in Electrolyte Media
The viscosity and stress relaxation behavior of silica suspensions in polyacrylamide (PAAm) solutions have been studied as a function of particle concentration, particle diameter, and molecular
Polymers | Free Full-Text | A New Empirical Model for Viscosity of Sulfonated Polyacrylamide Polymers | HTML
Copolymers of acrylamide with the sodium salt of 2-acrylamido-2-methylpropane sulfonic acid—known as sulfonated polyacrylamide polymers—had been shown to produce very promising results in the enhancement of oil recovery,
Application of polymer integration technique for enhancing polyacrylamide (PAM) performance in high temperature and high salinity reservoirs
Polyacrylamides (PAM) are widely used as water-soluble polymers producing gel in oil reservoirs to assist in oil extraction from reservoirs with high levels of heterogeneity. These gels are susceptible to degradation due to hydrolysis in harsh
Determining Safe Maximum Temperature Point (SMTP) for Polyacrylamide Polymer (PAM) in Saline Solutions
Press itatio Uranta KG, Gomari SR, Russell P, Hamad F. Determining Safe Maximum Temperature Point (SMTP) for Polyacrylamide Polymer (PAM) in Saline Solutions . J Oil Gas Petrochem Sci. (2018) 1(1): 00004. 2/9 75C [7,22]. However, in hotter
Factors effecting a loss of flocculation activity of polyacrylamide solutions: Shear degradation, cation complexation, and solution aging
Viscosity–aging of polyacrylamide solutions was observed over a period of several months, but was insufficient to affect the flocculation activity. In the presence of 3% ethanol or methanol, no aging was observed in solutions stored for over a
Polyacrylamide Gel Electrophoresis | Cleaver Scientific
Polyacrylamide gel electrophoresis (PAGE) is a technique use almost universally in life science laboratories. The goal of this technique is to separate a mixed sample of proteins to identify and quantify single proteins from the mixture. The
(PDF) A New Empirical Model for Viscosity of Sulfonated Polyacrylamide Polymers
14/6/2019 · a viscosity model for sulfonated polyacrylamide (AM / AMPS) polymers. Once the model had been developed and validated, the results were then derived from trend analysis and the interaction plots.
Performance of Bored Piles Constructed Using Polymer Fluids: Lessons from European Experience | Journal of Performance of Constructed Facilities
Brackish water from the Tagus River was used to mix the polymer at a concentration of 2 kg / m 3. The Marsh funnel viscosity of the fluid was 40 s. Although this viscosity value is rather low for PHPA polymers, it is within the
