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.

Paper field
Polyacrylamide is widely used as retention aid, filter aid, leveling agent, etc. in the papermaking field to improve paper quality, slurry dehydration performance, retention rate of fine fibers and fillers, reduce raw material consumption and environmental pollution, Used as a dispersant to improve the uniformity of paper. Polyacrylamide is mainly used in two aspects in the paper industry. One is to increase the retention rate of fillers and pigments to reduce the loss of raw materials and environmental pollution; the other is to increase the strength of paper. Adding polyacrylamide to the paper material can increase the retention rate of fine fibers and filler particles on the net and accelerate the dehydration of the paper material. The mechanism of action of polyacrylamide is that the particles in the slurry are flocculated and retained on the filter cloth by neutralization or bridging. The formation of flocs can also make the water in the slurry easier to filter out, reduce the loss of fibers in white water, reduce environmental pollution, and help improve the efficiency of filtration and sedimentation equipment
