Nonionic polyacrylamide is a water-soluble high molecular polymer that can absorb solid particles suspended in water to form large floccules. Therefore, it can accelerate the sedimentation of particles in the suspension, and has a very obvious effect of accelerating solution clarification and promoting filtration.
The high molecular weight of non-ionic polyacrylamide is very advantageous in water purification and is widely used in the treatment of chemical industrial wastewater and waste liquid, and municipal sewage treatment. When the sewage is acidic, non-ionic polyacrylamide is most suitable and can be used in combination with inorganic flocculants such as polyferric and polyaluminum.

- When using non-ionic polyacrylamide, it is recommended to prepare a 0.1% aqueous solution, preferably neutral water without salt impurities.
- When dissolving, sprinkle the non-ionic polyacrylamide evenly into the stirred water, control the stirring speed at 100~300rpm, and appropriate heating (<40℃) can accelerate the dissolution.
- Adjust the pH value of the treatment liquid to make the non-ionic polyacrylamide fully play its role (select the optimal pH value and dosage of non-ionic polyacrylamide through experiments).
- When adding non-ionic polyacrylamide solution, the mixing with the treatment liquid should be accelerated. After floccules appear, slow down the stirring speed to facilitate the growth of floccules and accelerate sedimentation.
- Nonionic polyacrylamide is used for organic wastewater treatment, such as electroplating, printing and dyeing, oil and fat factory wastewater, alcohol, monosodium glutamate, sugar, meat factory wastewater, urban sewage, etc.
- Used for papermaking enhancement to improve the dry and wet strength of paper. If nonionic polyacrylamide is added in the papermaking process, the wet paper strength of the paper can be increased by 10-20 times and the dry paper strength can be increased by 50%. It is mainly used for kraft paper, map paper, advertising paper, photo paper, etc.
- Used as an oilfield chemical additive.
- Used as a textile sizing agent, the sizing performance is stable, the sizing is less, the fabric breakage rate is low, and the cloth surface is smooth.
Nonionic polyacrylamide packaging, storage and transportation and precautions:
The packaging is 25Kg plastic-lined woven bags or paper-plastic composite bags, or packaged according to user requirements. During storage and transportation, pay attention to heat and moisture protection to prevent packaging damage. Dry powder products will absorb moisture and form lumps if exposed to the air for a long time.
