Polyacrylic acid (Polyscrylamide) is abbreviated as PAM, commonly known as flocculant or coagulant. Its molecular formula is: +CH2-CHn is a linear polymer with a molecular weight between 400 and 20 million. The appearance of solid products is white or slightly yellow powder. The liquid is colorless and viscous colloidal, soluble in water, and easily decomposed when the temperature exceeds 120 °C. Polyacrylamide molecule has a positive group (-CONH2), and can be dispersed in the solution adsorption and bridging of particulates, there is a strong flocculation, it is widely used in water treatment and metallurgy, paper, petroleum, chemical , textile, mineral processing and other fields.
