Nonionic polyacrylamide polyacrylamide is a homopolymer of acrylamide and is a linear polymer with high molecular weight and low molecular weight. Nonionic polyacrylamide is polymerized from acrylamide and sodium acrylate with oxidant, chain transfer agent and reducing agent. It has high purity and good solubility.The current use standard of non-ionic polyacrylamide is GB / t17514-2017.
It is most appropriate to use Non-ionic polyacrylamide, when the sewage is acidic. It is also used as an agent for the textile pulp, paper chemicals, water shutoff agent, and etc. Because of its non-ionic functional group, PH value and salts have little influence on Non-ionic polyacrylamide’s flocculation. In neutral or alkaline conditions, the flocculation effect is not as good as Anionic Polyacrylamide, but better than Anionic Polyacrylamide in acidic conditions.

Application and After-Sales Service:
1. Sewage treatment: when the suspended sewage is acidic, it is more appropriate to use non-ionic polyacrylamide as a flocculant. At this time, PAM plays the role of adsorption bridging, which makes the suspended particles produce flocculation and sedimentation, so as to achieve the purpose of purifying sewage. It can also be used for the purification of tap water, especially in combination with inorganic flocculant, which has a better effect on water treatment.
2. Coal mine washing: it can be used for the centrifugal separation of coal washing tailings, used in the precipitation and filtration of pulverized coal and slime, which can improve the recovery rate of pulverized coal and the plate passing rate.
3. Textile auxiliaries: chemical size can be prepared by adding some other chemicals, which can be used for textile sizing to improve adhesion, permeability, and desizing performance, so as to make textiles have antistatic property, reduce sizing rate, reduce wrinkling spots, cloth machine breakage, and falling objects.
4. Metallurgical beneficiation: such as zinc, manganese, copper flotation, and smelting, the leachate and residue can be added PAM to improve the separation efficiency.
5. Sand control and sand fixation: dissolve the non-ionic polyacrylamide into 0.3% concentration, add crosslinking agent and spray it on the desert to prevent and fix sand.
6. Soil humectant: it can act as a humectant in soil water retention and sand fixation, hillside grass planting, tree planting, sand soil sand fixation, and dust prevention,
We can provide water sample testing and on-site guidance.
