Nonionic polyacrylamide is a water-soluble polymer or polyelectrolyte. Because of its molecular chain contains a certain number of polar groups, it can be adsorbed by the water suspended solid particles, so that the particles between the bridge or through the charge and the particles condensed to form a large floc. Therefore, it can accelerate the sedimentation of particles in the suspension, there is a very clear way to speed up the clarification of the solution to promote filtration and other effects. Mainly used for a variety of industrial wastewater flocculation settlement, sediment clarification. Such as paper and pulp wastewater wastewater treatment, mineral processing and metal smelting process of wastewater treatment, steel and stone processing plant wastewater treatment.
1, good water solubility, in cold water can be completely dissolved.
2, add a small amount of non-ionic polyacrylamide, can be a great flocculation effect. Generally only need to add 0.01 ~ 10ppm (0.01 ~ 10g / m3), can play a full role.
3, while the use of non-ionic polyacrylamide and inorganic flocculants (polyferric sulfate, poly aluminum chloride, iron salts, etc.), can show a greater effect.
Non-ionic polyacrylamide flocculation effect is very strong, because it has:
1, to clarify the role of purification;
2, the role of sedimentation;
3, filter to promote the role;
4, thickening and other effects.
In the waste treatment, sludge concentration dehydration, mineral processing, coal washing, paper and so on, to fully meet the requirements of various fields.
1, when used, dubbed 0.1% concentration of aqueous solution to use neutral non-salt debris of water is appropriate.
2, dissolved, the non-ionic polyacrylamide evenly into the stirring water, stirring speed control in the 100 ~ 300rpm. Appropriate heating (<60 ° C), can accelerate the dissolution.
3. Adjust the pH of the treated solution to make the nonionic polyacrylamide fully functional (by selecting the optimum pH and the amount of nonionic polyacrylamide).
4, adding non-ionic polyacrylamide solution, should be accelerated with the treated liquid mixture, the emergence of flocs, slow down the stirring to facilitate the growth and accelerated sedimentation.
