Cationic Polyacrylamide is Known As Auxiliary Flocculant

1. Cationic polyacrylamide can purify water

As the content of organic matter in modern industrial and domestic drainage is greatly increased, the surface of organic matter particles is usually negatively charged, and cationic polyacrylamide flocculant can play the role of electric neutralization and adsorption bridging with particles in water, so as to destabilize and flocculate the particles in the system, which is conducive to sedimentation, filtration, and dehydration. It can effectively reduce the mass fraction of suspended solids in water, reduce the turbidity of the water, settle the virus and reduce the methane precursor in water, and reduce the total carbon content (TOC) in water. It has the characteristics of low dosage, low cost, low toxicity, and wide pH range.

2. Cationic polyacrylamide is known as auxiliary flocculant

Because the structural unit of cationic polyacrylamide flocculant contains an amide group, it is easy to form a hydrogen bond, which makes it have good water solubility. It is easy to obtain a variety of modifiers with branched or network structures by grafting or crosslinking. As an important flocculant, thickener, drag reducer, mud treatment agent, surfactant, soil conditioner, water and soil humectant, seed coating agent, and papermaking enhancer, it is widely used in petroleum exploitation, water treatment, textile, papermaking, beneficiation, medicine, agriculture and other industries. It is known as auxiliary flocculant.

Cationic polyacrylamide has positive groups in its molecules, which can adsorb and bridge with suspended particles dispersed in the solution. It has strong flocculation. It has high removal efficiency of organic matter in water, low dosage, fast sedimentation speed and low water production cost. It is a product that can not be replaced by other flocculants. It is also suitable for flocculation and sedimentation of red mud and mud liquid separation in the process of alumina preparation. The cationic molecular weight is high, which is mainly used for flocculation and precipitation of water suspension and suspension. When acidic and partial acidic solutions contain organic suspension, flocculation is very difficult. In this case, cationic polyacrylamide can effectively flocculate and precipitate, showing its outstanding performance. The aqueous solution in the form of 0.1% - 0.2% must be prepared with water with pH ≤ 7. It is very easy to hydrolyze after being prepared into a dilute solution. It should be used with or used up on the same day, and should not be stored for a long time.
