Application of Polyacrylamide in Paper Industry

The application of polyacrylamide in the papermaking industry. As a flocculant, polyacrylamide can promote the accumulation of suspended solids, colloids and other substances in sewage to form flocs for subsequent filtration, sedimentation and other treatment processes. In order to improve the strength of paper and save papermaking raw materials in the paper production process, polyacrylamide is used as a retention aid, a filter aid, etc. This can both improve the quality of the paper and reduce production costs.

Application of polyacrylamide in paper industry

Sludge dehydration: Polyacrylamide can be used in the sludge dehydration process of papermaking wastewater. Depending on the specific conditions of the wastewater, cationic polyacrylamide or anionic polyacrylamide can be used.

Fiber recycling: In the papermaking process, polyacrylamide can be used as a retention aid and a filter aid to improve the strength of the paper and save papermaking raw materials. In addition, it can also flocculate and precipitate the papermaking raw material fibers in the papermaking white water produced by the papermaking machine. The recycled papermaking raw materials can be used to produce paper with low quality requirements or for other purposes. The clarified water can also continue to use.

Water quality treatment: Due to its good adsorption and flocculation effect, polyacrylamide can quickly flocculate and precipitate impurities in the water, remove impurities in the water, and enable sewage recycling.

In general, using polyacrylamide to treat papermaking wastewater can not only achieve good treatment effects, but also use less amount. However, when using it, it is necessary to select the appropriate polyacrylamide model according to the specific wastewater conditions and treatment requirements.
