Polyacrylamide is an important water-soluble polymer, and has valuable properties such as flocculation, thickening, shear resistance, drag reduction, and dispersibility. These properties have different emphases with different derivative ions. Therefore, it is widely used in oil extraction, mineral processing, coal washing, metallurgy, chemical industry, papermaking, textile, sugar refining, medicine, environmental protection, building materials, agricultural production and other departments.
Anionic Polyacrylamide:
Anionic PAM is mainly used in minerals selection, metallurgy, coal washing, food, steel, spinning and papermaking industry which involves separation of solid-liquid and waste water treatment. Anionic PAM can also be used for oil well and oil extraction in oil industry, and retention aids and intensifier in papermaking industry.
Cationic Polyacrylamide:
Cationic polyacrylamide is mainly used as flocculants and dewatering reagents for industry waste water and sewage; retention aids and intensifier in paper making industry; waste water treatment in pharmaceutical, leather making, printing and dyeing industry waste water treatment, and organizer in textile industry.
Non-ionic Polyacrylamide:
Nonionic polyacrylamide is mainly used as flocculants with high selectivity in oil well fluid,and acidic waste water treatment.
