Polyacrylamide (PAM) is a polymer compound made from acrylamide monomers. It has the characteristics of strong water absorption and high molecular weight, and is widely used in various fields.
Polyacrylamide has ideal chemical stability and is non-toxic, odorless, non-irritating, and insoluble in most organic solvents.
The aqueous solution of polyacrylamide has colloidal properties, and its common manifestations are high viscosity and consistency. This high molecular weight polyacrylamide can form a network structure in the solution, making the solution viscous and having good gel properties.
Application Areas
1. Water treatment
Polyacrylamide is often used as a flocculant in water treatment. It can combine with suspended particles in the water to form larger particles, which are convenient for sedimentation and filtration. Due to its excellent water absorption, polyacrylamide can quickly absorb impurities in the water and improve the water purification effect.
2. Soil solidifier
Polyacrylamide can combine with soil particles to form a stable cementing structure. Adding polyacrylamide to the soil can improve the structural stability of the soil, inhibit soil erosion, and improve the soil's ability to retain water and fertilizer.
3. Oil extraction
Polyacrylamide is often used as an oil displacement agent in oil production. When polyacrylamide solution is injected into a reservoir containing crude oil, polyacrylamide can change the adhesion between the oil and water phases, reduce the interaction between crude oil and rock, and increase the recovery rate of crude oil.
4. Pulp and textile industry
Polyacrylamide can stabilize the fibers in pulp and improve the strength and quality of pulp. In the textile industry, polyacrylamide can be used to improve the softness and elasticity of textiles.
Polyacrylamide is a polymer compound widely used in water treatment, soil stabilization, oil extraction, pulp and textile industries. Its water absorption and high molecular weight make it play an important role in various application fields.
