Polyacrylamide emulsion is prepared by dispersion or inverse emulsion polymerization, which is a form of polyacrylamide liquid present. Besides the characteristics of solid polyacrylamide flocculants, through the molecular chain of polar groups to adsorb suspended solids in the water particles, the emulsion could formats the large flocs through bridge between the particles or electricity. Polyacrylamide emulsion is divided into two types, water-in-oil, and water-in-water. Unlike polyacrylamide powder, the drying process is not required in the emulsion type polyacrylamide manufacturing process. Therefore, the polyacrylamide emulsions molecular weight and water solubility than the same powder polyacrylamide molecular weight is higher. Water-in-oil emulsions are usually water-insoluble. Therefore, in the emulsion-type polyacrylamide manufacturing process, or in the use of emulsion before the dissolution of the dilution process, the need to add a hydrophilic surfactant, so that when the ...
