The nonionic polyacrylamide Gongyi manufacturers GB GB17514-2008. Lebang Water Treatment Materials Co., Ltd. production of non-ionic polyacrylamide is a chemically active polymers, the polymer obtained many valuable properties due to the molecular side chain amido loose-leaf paper. Non-ionic PAM flocculants without ionic functional groups, compared with the anionic PAM flocculant has the following characteristics: the flocculation performance water PH value and salts fluctuations; medium or alkaline conditions, its the flocculation effect (sedimentation rate) is not as good as the anion in acidic conditions better than anionic of floc strength than strong anionic polymer flocculant. Sand sand will be non-ionic polyacrylamide dissolved to a concentration of 0.3% crosslinking agent is added, spraying sand sand in the desert. Chemical grouting machine with 9.5 parts of nonionic amide and 0.5 parts of N - A bisacrylamide miscible as dams, foundations, tunnels, water shutoff chemical grouting agent. Nonionic polyacrylamide soil wetting agent to the water and sand fixation in the soil. Hillside grass. Planting trees, sand sand-fixation dustproof the moisturizers can play.
