Sodium Polyacrylate Used as Dispersing Agent

Product Information Dispersing and stabilizing mechanism of Sodium PolyacrylateAs a dispersant used in the polypropylene refining acid sodium its molecular mass is generally controlled in 3000-5000, it is a water-soluble polymer polyelectrolyte, when the polypropylene refining acid sodium dissolved in water in the water ionization, and the degree of ionization is large, the formation of polymer anions and many small molecule ions (Na+). Polymer anions and small molecule ions firmly adsorbed on the surface of the dispersed particles, so that the ions with the same charge, with the opposite charge of ions (Na +) free diffusion to the surrounding liquid medium, forming a stable diffusion layer of charged ions, that is, the double layer. As the ions with the same charge repel each other, the formation of electrostatic repulsion can prevent the pigment and other particles from flocculation in the aqueous medium, so as to achieve the purpose of dispersion. At the same time, due to the spatia…
