By injecting an aqueous solution of polyacrylamide, improve water flow rate ratio, so that in Extracts oil content increased. At present, foreign polyacrylamide aspects of the application in the oilfield few of the special geological conditions, Daqing Oilfield and Shengli Oilfield has been widely used polymer flooding technology. In mining, coal washing areas, the use of polyacrylamide flocculant can promote mining, coal washing water recycling solids settling, the water clear, while useful recyclable solid particles, to avoid environmental pollution; in the sugar industry, poly Acrylamide can accelerate the juice of fine particles sink to promote filtration and improve clarity of filtrate; in the breeding industry, polyacrylamide can improve water quality, increase water transmission performance, thus improving water photosynthesis; in medicine industry, the separation of antibiotics used polyacrylamide flocculant used as a tablet binder excipients and process water clarification agent; in the building materials industry, the polyacrylamide used as coatings thickening dispersant, saw stone coolant plates and ceramic bonding agent; in agriculture, polyacrylamide superabsorbent material can be used as soil and seed culture humectant agent. In the construction industry, polyacrylamide, can enhance the hardness of gypsum cement, asbestos cement speed spin speed. In addition, polyacrylamide also be used as natural or synthetic leather protective coatings and inorganic fertilizer granulation additives. A sewage treatment 1, Project Overview polyacrylamide flocculant and its copolymers are important, widely used in urban sewage and industrial wastewater treatment. Ours is a very poor area of ??water resources, coupled with the national water pollution, and thus protect water resources and control pollution is an important part of environmental protection. China's development of the next few years, the urban sewage treatment rate of 20-30%, industrial wastewater treatment rate of 84% in urban sewage facilities penetration rate of 70% of the water pollution control overall planning objectives. However, the technical aspects of water treatment technology updates slower. Currently, the flocculant is still mainly inorganic flocculants. Using polyacrylamide flocculant, the amount invested is one inorganic flocculants 100 points, but the effect of inorganic flocculants several times or more, and thus polyacrylamide application in wastewater treatment has extraordinary significance. Polyacrylamide can be divided by ionic properties of nonionic, anionic, anionic, and zwitterionic. Wherein the cationic polyacrylamide flocculant is an effective treatment. Current domestic production of cationic polyacrylamide technology, especially the production of high molecular weight cationic polyacrylamide is lagging behind technology, developed and produced mainly some low molecular weight cationic polyacrylamide powder products, and single product structure, can not meet the needs of the community, and high molecular weight cationic polyacrylamide is largely dependent on foreign imports. Therefore, the development and production of high molecular weight cationic polyacrylamide, and applied to the field of environmental protection, has extraordinary significance.
