Application of Anionic Polyacrylamide
1.the use of anionic polyacrylamide in industrial wastewater, mainly suspended particles, coarse, high concentration, particles with positive charge, water PH value is neutral or alkaline sewage, the treatment effect is good, in addition to steel mill wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater with anionic polyacrylamide effect is also outstanding.
2. Anionic polyacrylamide pam on the amylated factory and alcohol factory, also has the effect, can add anionic polyacrylamide, so that starch particles flocculate precipitation, and then the sediment by press filter into cake, can be used as feed. The wine tank of the liquor factory can also be dehydrated by cationic polyacrylamide and recovered by press filtration.
3. Industrial wastewater anionic polyacrylamide in the paper industry can be used as a burning lye clarification, fiber dispersant, can improve the degree of beating, filler retention agent, paper strengthening agent, can be used to improve the water filtration rate and water recovery.
4. The displacement agent of anionic polyacrylamide in the oil field can adjust the rheology of injected water, increase the viscosity of the driving fluid, improve the sweep efficiency of water drive, reduce the water phase permeability in the formation, so that water and oil can flow forward at a constant speed.
5. drilling mud materials, in the exploration and development of oil fields and geology, water conservancy, coal exploration, drilling polyacrylamide used as an additive to drilling mud materials, can increase the service life of the bit, improve the drilling rate and penetration, reduce the blockage during drilling change, and the effect of preventing well collapse is obvious.
6. used in textile, printing and dyeing industry. Anionic polyacrylamide is used as a sizing agent and finishing agent for fabric treatment, and pam can generate a flexible, anti-wrinkle, anti-mold protective layer. With its strong hygroscopicity, the breaking rate of spinning yarn can be reduced. Anionic pam as finishing agent can prevent static electricity and flame retardant of fabric.
