The main difference between anionic polyacrylamide and cationic polyacrylamide is that the anions are precipitated as inclined plates and the cations are treated as sludge.

Main Uses of anionic polyacrylamide:

(1) Anionic polyacrylamide is mainly used as coagulant: for floating particles, particles coarse, high concentration, positive charge, water PH value is neutral or alkaline wastewater, due to the molecular structure of the anionic chain has a certain amount of optically active groups, can adsorb floating solid particles in the water, so as to form a large inclined plate sedimentation tank between particles on the railway bridge. Therefore, it accelerates the foundation settlement of particles in the mixed solution, and has obvious practical effects such as accelerating the response of aqueous solution and promoting filtration. This product is widely used in chemical wastewater and sewage treatment and municipal engineering wastewater treatment. Industrial production of drinking water, purification and precipitation of high turbidity raw salt, coal preparation, mineral processing plant, metallurgy industry, iron and steel industry, zinc and aluminum manufacturing industry, electronics industry and other sewage treatment.

(2) Anionic polyacrylamide is widely used in petrochemical industry, oil field, drilling fluid, waste sludge treatment, avoid water channeling, reduce friction, improve oil recovery and tertiary oil recovery.

(3) Anionic polyacrylamide used as textile desizing agent, stable slurry characteristics, less pulp, textile damage rate is low, nylon cloth smooth.

(4) anionic polyacrylamide used in paper industry. One is to improve the rate of filling, color printing and so on. Reduce the outflow of raw materials and pollution to the natural environment; The second is to improve the compressive strength of printing paper (including dry compressive strength and wet compressive strength). In addition, the application of anionic polyacrylamide can also improve the tear resistance and porous structure of paper, resulting in improved visual effects and packaging printing characteristics. It is also used in food and tea bags.
