  • Influence of Molecular Weight on Polyacrylamide Viscosity

    Influence of Molecular Weight on Polyacrylamide Viscosity

    The viscosity of the polyacrylamide solution increases with the increase of the molecular weight of the polymer, because the viscosity of the polymer solution is generated by the interaction between the molecules during the movement of the molecules. When the relative molecular weight of the poly...

    Industrial wastewater treatment, clarification and purification, select anionic polyacrylamide

    In sewage treatment, polyacrylamide and polyaluminum chloride are the most used flocculants. Among them, polyaluminum chloride has a single type, and it is only necessary to select different alumina contents according to the treatment needs. However, PAM is different. The single ionic type is div...

  • Application of Nonionic Polyacrylamide

    Application of Nonionic Polyacrylamide

    As a linear polymer flocculant, polyacrylamide has the appearance of white particles. Because its molecular chain contains a certain amount of polar genes, it can absorb solid particles suspended in water, and bridge the particles to form large flocs. It can accelerate the sedimentation of the pa...
