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 anionic polyacrylamide used for?

Anionic Polyacrylamide is widely used in Oil & Gas, water treatment, textile, printing and dyeing, papermaking, mineral processing, coal washing, medicine, sugar, breeding, building materials, agriculture and other industries. It is known as the most widely used additive.

What is nonionic polyacrylamide (NPAM)?

Nonionic polyacrylamide (NPAM) is a type of high molecular polymer or polyelectrolyte. Its molecular chain contains nonionic polar groups that can adsorb suspended solid particles in water and bridge them to form a large flocculate.

Is anionic polyacrylamide toxic?

Anionic polyacrylamide has no systemic toxicity to aquatic organisms or micro-organisms. The polymer is much too large to be absorbed into tissues and cells. The functional anionic groups do not interfere with the functioning of fish gills or daphnia respirators.

What are the different types of polyacrylamide (PAM)?

So PAM chemical can be used for petroleum exploration, water treatment, textile, papermaking, mineral processing, medicine, agriculture and other industries, etc. The polyacrylamide (PAM) can be divided into four types, they are anionic PAM, cationic PAM, nonionic and amphoteric PAM. The following are their detailed introduction and specifications.

What is polyacrylamide used for?

Polyacrylamide can be used as a binder for pulp fibers in the paper industry. In agricultural applications, PAM powder can be used as a soil conditioner. It can also be used in mining, ore processing, food additives, textile manufacturing and gel electrophoresis.
