Anionic polyacrylamide Can be used as a plant fiber dispersant. Ultra-high molecular weight anionic polyacrylamide is a type of organic polymer that is easily soluble in water and can promote growth in trace amounts Dispersion of plant fibers. Dispersion is to distribute tiny solid particles as evenly as possible in another incompatible material. For the papermaking process, fibers, fillers and some additives are all water-insoluble, and they have a tendency to aggregate by themselves in aqueous solutions. , and different materials are often kept as far apart as possible due to incompatibility, making it difficult to obtain paper with uniform performance and ideal strength. Adding a dispersant can form a bilayer structure on the surface of the solid particles. The polar end of the outer layer of the dispersant has a strong affinity with water, which increases the degree to which the solid particles are wetted by water. The solid particles are kept away from each other due to electrostatic repulsion , to achieve good dispersion effect. |
