simple cationic polyacrylamide: a drag reducer iranian
a very simple cationic monomer and a cationic hydrophobically associating polyacrylamide were synthesized, and the polymer was to function as a drag reducer. the structures of monomer and polymer were characterized by ir and nmr, and the drag-reducing rate, below and above the critical association concentration, (cac) was tested. the modified polyacrylamide is a typical hydrophobically
polymers for coagulation and flocculation in water treatment,the classification of the synthetic organic polymers used in water and wastewater treatment operations is based on the ionic charge present, e.g. cationic, anionic and non-ionic polyelectrolytes. cationic polyelectrolytes formed the largest number of polymeric coagulants that have been used in cf operations.
- Can polyacrylamide be used as paper dispersant?
- Polyacrylamide could be used as paper dispersant, paper residence filter aid. The paper fibers and fillers in pulp are hydrophobic and tend to flocculate into clusters. It is difficult to produce paper with uniform properties and good strength. The addition of polyacrylamide promotes the dispersion of paper fibers and the formation of paper.
- Why is polyacrylamide used in paper industry?
- Polyacrylamide (PAM) in paper industry is widely used as retention agent, filter aid, homogenizer, and water treatment agent and so on. Its function is to improve the quality of paper, improve the pulp dehydration performance, improve the retention of fine fibers and fillers, and reduce the consumption of raw materials and environmental pollution.
- What is cationic polyacrylamide used for?
- Polyaluminium chloride, anionic or cationic polyacrylamide are commonly used in the recovery of white water from papermaking, while cationic polyacrylamide is commonly used in air flotation treatment.
