What is polyacrylamide? How does it work?

Polyacrylamide, codenamed PAM, is divided into three types: anionic, cationic and non-ionic. It is made by copolymerization of ionic monomer and acrylamide in different proportions. It is a kind of white polymer with good water solubility.

Because its molecular chain carries a certain number of positive, negative, neutral charges and strong adsorption genes, it can neutralize the charge on the surface of the suspended colloidal particles in the water to be treated, destroy its stability, and destabilize it. PAM flocculant The colloidal particles adsorb each other under the bridging effect of the active gene of high molecular polymer, and quickly form larger flocs to sink, thereby achieving the purpose of solid-liquid separation and water purification.

Polyacrylamide, CAS number 9003-05-8, molecular formula (C3H5NO)n, polyacrylamide is a linear organic high molecular polymer, but also a high molecular water treatment flocculant product, specializing in adsorbing water Suspended particles, linking and bridging between particles, make fine particles form larger flocs, speed up the sedimentation speed, and realize solid-liquid separation. This process is called flocculation. anionic polyacrylamide price Because of its good flocculation effect, PAM is widely used in sewage treatment as a flocculant for water treatment.

Polyacrylamide mesh: The mesh refers to the particle size or thickness of the material, and the mesh is the number of squares per unit area. The general definition refers to how many meshes there are in an area of 1 inch * 1 inch, that is, the sieve The number of meshes of the net.
