Polyacrylamide, English name is Poly (acrylamide), CAS number is 9003-05-8, and the molecular formula is (C3H5NO)n. Polyacrylamide is a linear organic polymer and a polymer water. The flocculant product is specially treated to adsorb the suspended particles in the water, and acts as a link between the particles to form a relatively large floc, and accelerates the sedimentation speed. This process is called flocculation because of its good flocculation effect. PAM is used as a flocculant for water treatment and is widely used in sewage treatment. Polyacrylamide mesh: The mesh number refers to the particle size or thickness of the material. The mesh number is the number of squares per unit area. The general definition refers to the number of meshes in the area of 1 inch * 1 inch, ie the sieve The number of meshes in the net.
