Product Description
Polyacrylamide is a type of linear polymer compound, which is a general term for linear water-soluble molecular chemicals formed by homopolymerization or copolymerization of acrylamide with other monomers. It is also one of the most widely used varieties of water-soluble polymer compounds, with good water solubility.
There are mainly Cationic Polyacrylamide (CPAM), Anionic Polyacrylamide (APAM), Non-ionic Polyacrylamide (NPAM), and Amphoteric Polyacrylamide.
The application of polyacrylamide in the papermaking industry is very extensive, which can be said to run through the entire papermaking process.
1. Paper Dispersant
Anionic polyacrylamide is used as a dispersant in papermaking, which can promote good dispersion of papermaking fibers and excellent paper forming effect at low dosage, improve pulp evenness and softness, and also increase the strength performance of paper. In the application of paper-making coating, the paper-making dispersant has high dispersion efficiency, stable paint viscosity, less foam, non-toxic, non corrosive, can improve the solid content of the paint, and has good fluidity and scrub resistance, can maintain the gloss of the paper, and is not easy to become moldy. Paper dispersants can also increase the speed of papermaking, save beating time, reduce energy consumption, and have significant economic benefits.
2. Paper Filter Aid
Cationic polyacrylamide is used in the retention process of papermaking to utilize the negative charge on the surface of fillers, cationic polymer polyelectrolytes are used to cation it, increase the adsorption of filler particles with pulp fibers and fine fibers, thereby improving the one-way retention rate of fillers, reducing the filler content in white water, reducing loss, and reducing costs. It can also reduce the concentration and ash content of pulp on the wire, and extend the lifespan of the formed mesh And the smoothness and opacity of the paper can be improved.
3. Paper Wastewater Treatment Agent
Polyacrylamide can also be used for papermaking wastewater treatment and fiber recovery, which is conducive to meeting discharge standards. Anionic polyacrylamide is used for air flotation and sedimentation, while cationic polyacrylamide is used for mud pressing.
Lvyuan Water Treatment provides various types of polyacrylamide, including anionic Powder, Cationic Powder, Non-ionic Powder, and Anionic Emulsion.
