With more adding of the anionic polyacrylamide, there is only a little influence to the paper strength, but the paper evenness gradually gets worse. 2. The polyacrylamide can be used as the reinforcing agent. As the water soluble high polymer, in recent year, the polyacrylamide is paid more attention in the papermaking industry as the reinforcing agent, it can work as both the dry strengthening agent but also the wet strengthening agent.

Anionic polyacrylamide - wastewater treatment chemicals

Anionic polyacrylamide is water-soluble linear polymer synthesized with high degree of polymerization. It is widely used in oil recovery, mineral processing, metallurgy, chemical industry, papermaking, textile,medicine, environmental protection, building materials, agriculture and other industries. Anionic polyacrylamide is especially suitable for water treatment with positively charged suspended solid particles, which has both flocculant and thickening property.
