Polyacrylamide is an important water-soluble polymer with valuable properties such as flocculation, thickening, shear resistance, drag reduction and dispersion. These properties vary with the derivative ions.
It is mainly used for the sludge dewatering and decrease the rate of water content of sludge, and it can also be used for papermaking to improve dry & wet strength of paper, to improve dry and wet strength of paper and to increase the reservation of tiny fibers & fillings. Therefore, it is widely used in oil extraction, mineral processing, coal washing, metallurgy, chemical industry, papermaking, textile, sugar making, medicine, environmental protection, building materials, agricultural production and other sectors.
