What are the uses of anionic polyacrylamide (APAM)?

Anionic polyacrylamide (APAM) is a water-soluble polymer with negative charges on the molecular chain. Its working principle, purpose, usage and precautions are as follows:

1. Principle of action

The working principle of anionic polyacrylamide is mainly reflected in two aspects: first, through adsorption, the surface of suspended particles is negatively charged, so that the particles repel each other and achieve the purpose of dispersion; second, through bridging of polymer chains The action causes suspended particles to aggregate with each other and form larger flocs, thus accelerating the settling or filtration process.

2. Purpose

Anionic polyacrylamide is widely used in various fields due to its unique properties, such as:

Water treatment: APAM can be used as a flocculant to treat various industrial wastewater and domestic sewage, accelerate the settlement of suspended particles, and improve water quality.

Papermaking: APAM can be used as a paper reinforcing agent to increase the strength and toughness of paper and improve the performance of paper.

Oil extraction: APAM can be used as an oil displacing agent to improve oil recovery.

Textile printing and dyeing: APAM can be used as a sizing agent, finishing agent, etc. to improve the quality and performance of textiles.

Other fields: APAM can also be used in agriculture, medicine, food and other fields.
