Application of cationic polyacrylamide FLOPAM FO4190 4490 4650

Polyacrylamide PAM introduction:

Polyacrylamide (PAM) is a linear polymer with a molecular weight of between 3 million and 25 million. The solid product has a white powder appearance, and the liquid is colorless and viscous colloidal. It is soluble in water and almost insoluble in organic solvents. The application should be dissolved at room temperature and decomposed easily when the temperature exceeds 150℃. It is non-dangerous goods, non-toxic and non-corrosive. Solid PAM has hygroscopicity, flocculation, adhesion, resistance reduction, thickening, and good stability. The molecule of the product can bridge adsorption with suspended particles dispersed in the solution and has a strong flocculation effect. The company's polyacrylamide products are divided into: anionic type, cationic type, non-ionic type, amphoteric ion type of different molecular weight different degrees of the four series of products. Widely used in water treatment and metallurgy, paper making, petroleum, chemical, textile, sugar, medicine, coal washing, mineral processing and other fields.

Polyacrylamide PAM classification:

1, amphoteric polyacrylamide ACPAM 2, non-ionic polyacrylamide NPAM 3, cationic polyacrylamide CPAM 4, anionic polyacrylamide APAM

Polyacrylamide PAM product uses:

Polyacrylamide is divided into: anionic, cationic and non-ionic.

Anionic type is mainly used for domestic production water, industrial and municipal sewage treatment. It is also suitable for flocculation and sedimentation of red mud and mud separation in the process of alumina preparation. Cationic type with high molecular weight is mainly used for flocculation and precipitation of water suspension and turbidity. It is very difficult to flocculate when acidic and partial acidic solutions contain organic turbidity. In this case, cationic polyacrylamide can effectively flocculate precipitation, showing its outstanding performance. Use the form of 0.1-0.2% aqueous solution, must be prepared with water PH≤7, with dilute solution after easy hydrolysis. It should be used together or used up on the same day, not for a long time. Polyacrylamide molecules have positive genes (-CONH2), can be dispersed in the solution of suspended particles absorption and bridge, has a strong flocculation effect, so widely used in water treatment and power, mining, coal preparation, asbestos products, petrochemical, paper making, textile, sugar, medicine, environmental protection, etc.

And practical application can make the following conclusions:

Polyacrylamide anionic PAM is suitable for higher concentration of positively charged inorganic suspended matter, as well as suspended particles coarse (0.01-1mm),pH value of neutral or alkaline solution.

Polyacrylamide cationic PAM is suitable for suspension with negative charge and organic matter.

Polyacrylamide non-ionic PAM is suitable for the separation of suspended solids in the mixed state of organic and inorganic, and the solution is acidic or neutral.

Polyacrylamide amphoteric ionic PAM is suitable for wastewater treatment where the properties of suspended solids and PH value vary
