Polyacrylamide (PAM) is a general designation of homopolymers of acrylamide or copolymerized with other monomers. It is one of the most widely used water-soluble polymers. Because the structural unit of polyacrylamide contains amide group, it is easy to form hydrogen bond, which makes it have good water solubility and high chemical activity. It is easy to obtain a variety of modifiers with branch chain or network structure by grafting or cross-linking. It is widely used in oil exploitation, water treatment, textile, paper making, mineral processing, medicine, agriculture and other industries, and it is called "one hundred industry auxiliaries".
Polyacrylamide is widely used as retention aid, filter aid and evenness agent in the field of papermaking to improve the quality of paper, the dehydration performance of pulp, the retention rate of fine fibers and fillers, reduce the consumption of raw materials and environmental pollution. As a dispersant, it can improve the evenness of paper. Polyacrylamide is mainly used in two aspects in papermaking industry, one is to improve the retention rate of fillers and pigments to reduce the loss of raw materials and environmental pollution; the other is to improve the strength of paper. Adding polyacrylamide to the paper material can improve the retention rate of fine fiber and filler particles on the net and accelerate the dehydration of paper material. The mechanism of polyacrylamide is that the particles in the slurry can be retained on the filter cloth by electric neutralization or bridging. The formation of flocs can also make the water in the slurry easier to filter out, reduce the loss of fiber in the white water, reduce environmental pollution, and improve the efficiency of filtration and sedimentation equipment.
