Product Detail

The non-ionic polyacrylamide series is a low-ionic linear polymer with high molecular weight synthesized by a special process. Because of its special group, it imparts flocculation, dispersion, thickening, bonding, film formation, gelation, and stabilization of colloids. The nonionic polyacrylamide can be classified into an ultrahigh relative molecular weight polyacrylamide, a high relative molecular weight polyacrylamide, a medium relative molecular weight polyacrylamide, and a low relative molecular weight polyacrylamide according to the molecular weight. The ultra-high relative molecular weight polyacrylamide is mainly used for tertiary oil recovery in oil fields. The high relative molecular weight polyacrylamide is mainly used as a flocculant. The medium molecular weight polyacrylamide is mainly used as a dry strength agent for paper, and the low relative molecular weight polyacrylamide is mainly used. Do a dispersant.

◇ Use:

1. In the non-ionic polyacrylamide mining industry, a large amount of water is usually used. Finally, it is necessary to recover useful solids in the water and purify and recycle the wastewater. Application of non-ionic polyacrylamide flocculant can promote solid sinking, liquid clarification and mud cake dehydration, which can improve production efficiency, reduce tailings loss and water consumption, reduce equipment investment and processing costs, and eliminate the environment. Pollution. Example: Leaching of molybdenum, precipitation and separation of gold, and recovery of uranium ore.

2. Non-ionic polyacrylamide In the process of coal washing, the precipitation and filtration of coal powder and slime are the main economic problems and pollution control problems. The non-ionic polyacrylamide series can reduce soil coloration, pipe blockage, pump maintenance and river water pollution, increase production capacity, recover pulverized coal and increase filtration rate, and also completely clarify water;

3. In the electrolytic refining process, the metal precipitate can be homogenized to make the coating more bright and improve the current efficiency;

4. In the inorganic fiber slurry (asbestos-cement product), the asbestos-cement product can be improved in drainage, and the strength of the asbestos board material can be improved; in the insulating plate, the bonding ability of the additive and the fiber can be improved;

5. It can be used as an additive for plastic wrap and agricultural film;

6. The composite material of non-ionic polyacrylamide can be used as grouting material for deposits, ponds, dams and foundations;

7. In the soil improvement, the solidity of the soil aggregate structure can be enhanced, and the water content of the soil and the bearing load of the soil structure can be increased;

8. Polyacrylamide gel can be used to separate substances that maintain biological activity, controlled release of drugs and entrapment of enzymes, protein electrophoresis, and gel electrolyte of batteries.

9. It is used for sewage treatment. When the sewage is acidic, this product has special effects, and can also be used together with polyaluminum and polyferric sulfate.

◇ Note:

1. Non-ionic polyacrylamide amine PAM is formed by bridging many fine particles or oil beads in the sewage through the long chain of the polymer to form a bridge. It is a very flocculating flocculating agent with a faster flocculation rate than anionic PAM. When used in the oily wastewater treatment of oil fields, it is usually used in combination with aluminum salts.

2, before use, it is necessary to determine the optimal dosage by experiment. The dosage is too low, it does not work, and the dosage is too high, but it is counterproductive. This is because, above a certain concentration, PAM not only does not flocculate, but acts as a dispersion stabilizer.

3. Use a lower concentration when adding the drug to ensure even mixing.
