Which industry uses anionic polyacrylamide?

Textile Industry: As a sizing agent, anionic polyacrylamide can improve fabric breakage rates, making the fabric surface smooth. Paper Making Industry: In the paper making process, anionic polyacrylamide can increase the retention rate of fillers and pigments, reduce raw material loss, and enhance paper strength.

What is polyacrylamide (PAM) used for?

In water treatment and industrial production, polyacrylamide (PAM) is widely used as an important flocculant in wastewater treatment, pulp production, ore processing, and other fields. Based on its ionic properties, PAM can be divided into anionic polyacrylamide (APAM) and cationic PAM (CPAM).

Can polyacrylamide be used in agriculture?

The use of polyacrylamide in agriculture might contaminate the food with acrylamide, which is a carcinogen and neurotoxin. Based on type, the market is segmented into cationic, anionic, and non-ionic. Based on water treatment, oil & gas, paper making, and others.

Which is better cationic or anionic polyacrylamide?

Cationic PAM is especially suitable for treating negatively charged organic substances such as high-concentration colloids and suspended solids in wastewater treatment. Due to its complex production process and superior performance, cationic PAM is usually priced higher than anionic polyacrylamide.

How does anionic polyacrylamide (Apam) work?

Anionic polyacrylamide (APAM) carries a negative charge, and its molecular chain contains polar groups such as carboxyl groups. These groups can neutralize charges with positively charged particles in water and form larger flocs through bridging, thus accelerating the sedimentation of particles in the suspension.

Is polyacrylamide ionic or cationic?

Due to its excellent flocculation, thickening, and enhancing properties, polyacrylamide is widely used in various industrial fields such as water treatment, paper making, petroleum, coal, and mining metallurgy. Based on its ionic characteristics, polyacrylamide is mainly divided into three categories: anionic, cationic, and non-ionic.
