What are anionic polyacrylamides?

Anionic polyacrylamides (PAMs) are a class of synthetic water-soluble polymers (composed of long chains of acrylamide monomer) used as flocculants. They are available in dry powder form, liquid emulsion, and gelatinous blocks.

What is the viscosity of polyacrylamide solution?

The viscosity of a polyacrylamide solution mainly reflects the internal frictional resistance between liquid molecules due to flow or relative movement. This internal friction resistance is related to the structure of the polymer, the nature of the solvent, the concentration of the solution, temperature and pressure and other factors.

How is polyacrylamide (PAM) a polymer with high molecular weight?

Polyacrylamide (PAM) with high molecular weight was synthesized by microemulsion method. Polyacrylamide was used as monomer, and a self-made initiator was used for polymerization under the condition of coexistence with sodium carbonate. The optimal polymerization parameters of PAM are determined: pH value of solution was 12. 3.

What are the three types of polyacrylamide (PAM)?

Polyacrylamide (PAM) and its derivatives are multifunctional water-soluble polymers, which can be divided into three types: nonionic, cationic and anionic. Polyacrylamide (PAM) with high molecular weight was synthesized by microemulsion method.

What is anionic polyacrylamide (Apam)?

Anionic polyacrylamide (APAM) is its negative charge, which makes it highly effective in a wide range of applications. Anionic polyacrylamide (APAM) is highly water-soluble, which means that it can be easily dissolved in water and other aqueous solutions. This makes it easy to use in various applications, such as in the treatment of wastewater.

What is the difference between anionic acrylamide copolymer retention aids and strength agents?

Anionic acrylamide copolymer retention aids typically have molecular masses in the range of 5 to 20 million grams per mole. The strength agents typically have molecular masses in the hundreds of thousands. Another difference is in the form delivered to the mill.
