Non-ionic polyacrylamide is uniformly polymerized with acrylamide, with high purity, good solubility and high molecular weight. This series of products have linear polymers with high molecular weight and low ionic degree. Because of its special gene, it has the functions of flocculation, dispersion, thickening, bonding, film forming, gel and colloid stabilization. Scope of application: sewage treatment agent: when the sewage shows acidic suspension, it is most suitable to be used as a flocculant, especially when used with inorganic flocculant, the water treatment result is the best. Textile industry: adding some other chemicals can be configured as chemical size for textile sizing; Sand prevention and sand fixation: add cross-linking agent at a certain concentration, spray it on the desert, and solidify it into a film to prevent and fix sand. It can be used as soil humectant in arid areas. It can also be used in construction industry, construction glue, interior wall coating, etc
