Nonionic Polyacrylamide (NPAM) is an important polymer compound widely used in water treatment, oil mining, pulp and paper, textile printing and dyeing and other fields.

NPAM is an uncharged polymer with the chemical formula (C3H5NO)n. It is obtained by polymerizing acrylamide monomer. Compared with ionic polyacrylamide, NPAM is uncharged and therefore has lower ion adsorption capacity.

NPAM has the following characteristics:

Highly water absorbent: Due to its polymer structure, NPAM is able to absorb large amounts of water, forming a colloidal solution.

High viscosity: NPAM solutions have high viscosity and can develop controllable rheological properties under various conditions.

Good stability: NPAM can maintain good stability under different water quality conditions and is not easily degraded.

Non-toxic: NPAM is non-toxic to the environment and organisms and will not cause pollution to the environment.

NPAM is widely used in many fields, including the following aspects:

1. Water treatment field
As an excellent flocculant and water purification agent, NPAM is widely used in sewage treatment and drinking water purification processes. It can effectively remove suspended solids, colloids and organic matter and improve water quality.

2. Oil extraction field
NPAM can be used as an oil displacing agent in oil exploration. It can increase the fluidity of oil and improve oil recovery. In addition, NPAM can also be used to prevent water infiltration and reduce groundwater waste.

3. Pulp and paper industry
NPAM can be used as an additive in pulp and paper making processes. It can increase the viscosity and strength of pulp and improve the quality of paper.

4. Textile printing and dyeing field
NPAM can be used as a dispersant and thickener in the textile printing and dyeing industry. It improves dye dispersion and liquidability.
