The nonionic polyacrylamide produced is a water-soluble polymer. According to the fact that the molecular chain contains a certain number of polar groups, it can adsorb solid particles suspended in water to bridge the particles or agglomerate the particles to form large flocs through charge neutralization. Therefore, it can accelerate the sedimentation of particles in suspension, and has very obvious effects on accelerating solution clarification and promoting filtration. Mainly used for flocculation, sedimentation and sedimentation clarification of various industrial wastewaters. Such as papermaking and pulp wastewater treatment, wastewater treatment in mineral processing and metal smelting processes, wastewater treatment in steel plants and stone processing plants, etc.

Product Features of Nonionic Polyacrylamide
It has good water solubility and can be completely dissolved in cold water.
Add a small amount of non-ionic polyacrylamide to achieve a great flocculation effect. Generally just adding / will give full effect.
Using non-ionic polyacrylamide and inorganic flocculants polymerized iron, polyaluminum chloride, iron salts, etc. at the same time can show greater effects.
How to use non-ionic polyacrylamide
When using it, prepare a concentrated aqueous solution. It is advisable to use neutral water without salts and impurities.
When dissolving, sprinkle the non-ionic polyacrylamide evenly into the stirring water and control the stirring speed. Appropriate heating can speed up dissolution.
Adjust the value of the liquid to be treated so that the non-ionic polyacrylamide can fully exert its effect and select the optimal value and dosage of non-ionic polyacrylamide through experiments.
When adding non-ionic polyacrylamide solution, the mixing with the liquid to be treated should be accelerated. When flocs appear, the stirring speed should be slowed down to facilitate the growth of flocs and accelerate settlement.
About the molecular weight compounding of non-ionic polyacrylamide
The optimal dosage must be determined through experiments before use. If the dosage is too low, it will not work, and if the dosage is too high, it will have the opposite effect. This is because when the concentration exceeds a certain concentration, it not only has no flocculation effect, but also has a dispersion and stabilizing effect.
Ionic type is used as a highly selective flocculant in low-solid phase drilling mud using bentonite, because it can flocculate the drilled cuttings while keeping the bentonite in a dispersed state.
A lower concentration should be used to ensure uniform mixing.
The ionic type uses its long polymer chain to absorb many small particles or oil beads in the sewage and then entangle them together to form a bridge. It is a flocculant with very strong flocculation ability and its flocculation speed is faster than that of anionic type. In the treatment of oily wastewater in oil fields, it is usually used in conjunction with aluminum salt
