Experimental study and application of gels formed by nonionic

Nonionic polyacrylamide (NPAM) and phenolic resin cross-linker were purchased from Yuguang Co. Ltd., China. The hydrolysis degree and average molecular weight of NPAM were 3.31% and 9,650,000 g/mol, respectively. The low salinity of brine (492.08 mg/L) was used in all experiments. Preparation of gels

Rheology Properties of Underwater Cement Paste with Nonionic Polyacrylamide

Xian zuo & Hengrui Liu 164 Accesses Explore all metrics Abstract In this article, underwater cement paste (UWP) was fabricated through using the high molecular nonionic polyacrylamide (PAM) as anti-washout admixtures (AWAs). The traditional coaxial rotary method was used to systematically investigate UWPs rheology parameters.

Breakage and regrowth of flocs formed by sweep coagulation

The breakage and regrowth of flocs formed by sweep flocculation were investigated on different flocculation mechanisms using additional dosage coagulant of poly aluminium chloride (PACl) and non-ionic polyacrylamide (PAM) to explore the reversibility after floc breakage. The optimal dosage of PACl was 0.15 mM (as alum), and zeta potential exceeding 1 mV meant that sweep flocculation was
