Anionic polyacrylamide is kind of ultra-high molecular weight polymer after  copolymerization by acrylamide and acrylic acid salt ,the  molecular weight can be up to more than 18 million, has a strong adsorption bridge effect,we can choose different anionic polyacrylamide with different molecular weight according to different applications and requirements for product performance .

Application range of anionic polyacrylamide:

1. Used in textile and printing and dyeing industry. Anionic polyacrylamide can be  used as sizing agent and finishing agent for fabric treatment, as well as to produce a protective layer that is flexible, wrinkle resistant and mildew resistant. By virtue of its strong hygroscopicity, the breaking rate of spinning can be reduced. Polyacrylamide can be used as a finishing agent to prevent static electricity and flame retardancy of fabrics. When used as auxiliaries for printing and dyeing, polyacrylamide can make products with good adhesion fastness and high brightness, and can also be used as non-silicon polymer stabilizer for bleaching.

2, mainly used as polyacrylamide: for suspended particles, coarse, high concentration, particles with a positive charge, water PH value is neutral or alkaline sewage, because anionic polyacrylamide molecular chain contains a certain amount of polar base can adsorb suspended solid particles in water, make the bridge between particles form a large polyacrylamide. Therefore, it accelerates the settlement of particles in the suspension, accelerates the clarification of the solution, promotes filtration and other effects. The product is widely used in chemical industry wastewater, waste liquid treatment, municipal sewage treatment. Water industry, high turbidity water purification, settling, coal washing, mineral processing, metallurgy, iron and steel industry, zinc, aluminum processing industry, electronic industry and other water treatment.

3, Used in the petroleum industry, has been widely used in  drilling mud, waste mud treatment, prevent water channeling, reduce friction, improve recovery, three times oil recovery.

4, used for paper industry.first is to improve the retention rate of filler, pigment, etc. To reduce the loss of raw materials and environmental pollution;second is to improve the strength of paper (including dry strength and wet strength), in addition, the use of anionic polyacrylamide can also improve the paper tear resistance and porosity, to improve the visual and printing properties, but also used in food and tea packaging paper.

5, other industries.it can be used for for of sugarcane juice clarification and phosphorus float extraction of syrup in garcane sugar, sugar beet sugar production.i can be also used in feed protein recovery, stable quality, good performance, recovery of protein powder to chickens and raising the survival rate of weight gain, no adverse effects of egg production, synthetic resin coating, civil water plugging grouting materials, building materials industry, improve the quality of cement, construction adhesive, caulking repair and plugging agent, soil improvement, electroplating industry, printing and dyeing, etc.
