Main Application of Noionic polyacrylamide Mine Washing: The product can be used in coal washing tailing centrifugal separation, can be used in sedimentation and filtration of coal powder and coal mud, and can improve the recovery rate of coal powder and the filtration speed. Textile Auxiliary Agent: The product can be added with some other chemicals to prepare chemical grout, is used to starch textiles, can improve the adhesive property, penetrability and desizing performance, enables the textile to have electrostatic prevention performance, reduces the desizing rate, and reduces the starch mixing spots, cloth machine breaking efficiency, and falling objects. Sewage Water Treatment: When sewage water systems are acidophilic, it is more suitable to select nonionic-polyacrylamide, the product can be matched with flocculating agent PAC, aluminium sulphate and the like, and it has the best effect in water treatment. Metallurgical Mineral Dressing: It can be used in floatation and smelting of Zinc, manganese and copper mines, its leachate and slag can be added into PAM to improve the separation efficiency. Sand Prevention and Solidification: The nonionic-polyacrylamide is dissolved into 0.3% concentration, cross-linking agent is added, and the product can be sprayed on desert to prevent and solidify sand. Chemical mudding agent: 9.5 share nonionic-polyacrylamide is used and is mixed to 0.5share NN-methylene diacrylamide, the product can be used as chemical mudding agent for plugging water of dikes, ground foundation, channels and the like. Oil field profile controlling and water-plugging agent: The product can be matched with lignocellulose, a certain amount of chemical adhesive can be added, and the product can be used as oil field profile controlling and water-plugging agent. Soil humectant: It can preserve water and solidify sand for soil and can play a role of humectant on slope grass planting, tree planting, and sand solidification
