How To Choose The Right Polyacrylamide Type?
31-01-2024
1. In the flocculation and sedimentation process of sewage, medium-hydrolyzed anionic polyacrylamide is selected; for air flotation of sewage, nonionic polyacrylamide and low-ionic cationic polyacrylamide pam are mostly used; for sludge dehydration, cationic polyacrylamide is widely used.
2. Most household papers use anionic polyacrylamide as a dispersant. If it is high-grade paper, polyethylene oxide can be used. In the production process of paperboard, low-ionic cationic polyacrylamide pam is used as a retention and filter aid. Polyacrylamide pam used in the papermaking process need to control the insoluble content of the product, the lower the better.
3. When used as a fragrance binder and mud thickener, its main function is thickening. Generally, anionic polyacrylamide pam is chosen. The higher the molecular weight, the better, because the higher the molecular weight, the higher the viscosity.
