Polyacrylamide degradation and its implications in environmental systems | npj Clean Water
High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity
An anionic polyacrylamide solution was characterized in elongational flow by combining laser-Doppler velocimetry to determine the strain rate in the flow direction and the two-color flow-induced birefringence method to measure the first normal
Factors affecting the viscosity of polyacrylamide - Cpolymer
The viscosity of polyacrylamide solution mainly reflects the internal frictional resistance between liquid molecules due to flow or relative movement. The internal friction resistance is related to the structure of the polymer, the nature of the
Anionic Polyacrylamide is water-soluble polymers which is insoluble in most organic solvents, It presents high polymer electrolyte characteristics in neutral and alkaline mediums. With good flocculation, it can reduce the frictional resistance

Anionic Polyacrylamide Chemicals Flocculant Water Treatment Polymer 1. Product characteristics Anionic polyacrylamide (APAM) series products are water-soluble linear polymers synthesized under high degree polymerization, easily soluble in water,
are high molecular weight water soluble or swellable polymers formed from acrylamide or its derivatives. Their glass transition temperature is well above room temperature (> 400 K). The only commercially important polyacrylamide is poly
Polyacrylamide, a widely used flocculant in water treatment - Cpolymer
They are synthetic polyacrylamide series products, mainly divided into anionic, cationic, nonionic and zwitterionic. Polyacrylamide (polyacrylamide), often abbreviated as PAM, various PAM used in water treatment, in essence, a certain proportion
Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH2CHCONH2-). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for
Quantitative characterization of polyacrylamide–shale interaction under various saline conditions
The interaction of anionic polyacrylamide with the different shale samples was plotted as a function of anionic polyacrylamide concentration. The concentration of shale was kept constant at 0.5 lb/bbl, and the concentration of anionic polyacryla
Therefore, polyacrylamide in the high salinity, high temperature, and high shear, the oil displacement effect is not ideal. SINOFLOC R & D team was modified with acrylamide and 2-acrylamide-2-methyl propane sulfonic acid (AMPS) as the raw
Shear rheology of anionic and zwitterionic modified polyacrylamides - ScienceDirect
