Polyacrylamide emulsion is a new polymer material made of acrylamide through special process polymerization since 1960s. The polyacrylamide emulsion is by a polymerization reaction in which a water-soluble monomer (acrylamide) is dissolved in an aqueous phase and dispersed in a non-polar liquid by means of an emulsifier to form a water-in-oil type emulsion. Inverse Emulsion Polymerization is a way that water-soluble monomer has the same high polymerization rate and high molecular weight as conventional emulsion polymerization. This could enables efficient polymerization of water-soluble monomers into a milky polymer and the reaction temperature is smooth and easy to control which could reduce the cross-linking and branching reaction. The product molecular weight can be free to adjust and is conducive to the application. The drag reduction agent is the most important component in the slick water fracturing fluid system. When the polyacrylamide emulsion is used as the drag reducing age...

In papermaking process, fibers, fillers and some additives are not water-insoluble, so they are easy to accumulate in aqueous solution. Moreover between the different materials as far as possible from the incompatibility away, so it is difficult to get uniform performance and ideal strengthen paper. In order to solve the long fiber in the process of this problem, the using of polyacrylamide has following advantages: to improve the retention rate of fillers, pigments and so on. To reduce the loss of raw materials and environmental pollution. to improve the strength of the paper (including dry and wet strength). to improve the tear resistance and porosity to improve visual and printing performance. The advantages of using polyacrylamide as a paper dispersant are also manifested in the fact that the product is soluble in water and forms a high viscosity liquid which promotes good dispersion of papermaking fibers and excellent paper forming effect at low added levels to impro...
