Polyacrylamide, also known as PAM, is often used in the field of water treatment and purification. Because of the linear water-soluble polymer, the long molecular chain structure can play the role of flocculation, precipitation and purification, and has a high viscosity after dissolution, so it can also be used as a binder, thickening agent, resistance reducer. From the point of view of physical and chemical properties, with several characteristics, therefore, analyze the s...
