Anionic polyacrylamide is mainly used as flocculant: for coarse suspended particles, high concentration, positive charge, water PH value is neutral or alkaline sewage, anionic polyacrylamide molecular chain contains a certain amount of ji groups, can adsorb solid particles suspended in water, particles bridge the formation of large floc. Therefore, it accelerates the settlement of particles in the suspension, and has obvious effects of accelerating solution clarification and promoting filtration. Anionic polyacrylamide is widely used in chemical industry wastewater and waste liquid treatment, urban sewage treatment. Water treatment of tap water, purification of high turbidity water, precipitation, coal washing, mineral processing, metallurgy, iron and steel industry, zinc and aluminum processing industry, electronics industry, etc.

3 Anionic polyacrylamide can also be used in the petroleum industry, oil production, drilling mud and waste mud treatment, prevent water channeling, reduce friction, improve oil recovery and tertiary oil recovery, widely used.

4 Anionic polyacrylamide can also be used in the paper industry. First, it can improve the retention rate of fillers and pigments. Reduce raw material losses and environmental pollution; The second is to improve the strength of the paper. In addition, PAM improves the tear resistance and porosity of the paper, which improves visual and printing performance. It is also used in food and tea paper.

5. Anionic polyacrylamide is used in other industries, food industry, sucrose and beet sugar production in cane juice clarification and syrup phosphorus flotation extraction. Fermentation fluid flocculation clarifying industry is also used for feed protein recovery, stable quality, good performance. The recovered protein powder had no adverse effects on survival rate, weight gain and egg production. Synthetic resin coating, water plugging civil grouting materials, building materials industry, cement quality improvement, construction industry with adhesive, caulking repair and water blocking agent, soil improvement, electroplating industry, printing and dyeing industry, etc.
