Polyacrylamide selection

Polyacrylamide products can be used as thickeners, flocculants, adhesives, drag reducers, dispersants, etc. and are widely used in water treatment, metallurgy, papermaking, petroleum, chemical industry, textiles, mineral processing and other fields. In the process of treating sewage, a large amount of polyacrylamide water purifier is used, which not only makes the sewage meet the national discharge standards, but also saves some costs by removing some metal useful substances in the sewage. So how do we determine the selection of polyacrylamide water purifier? 1. Determine the model: Polyacrylamide is divided into anionic, cationic, nonionic and zwitterionic according to its ionic characteristics. We must first determine which type of polyacrylamide water purifier to choose based on the nature of the sewage and the composition of the ionic impurities contained in the sewage. 2. Determine the molecular weight: After determining the model of the polyacrylamide water purifier, we need to analyze the sewage and then select the molecular weight of the polyacrylamide water purifier used to treat sewage. 3. Adding content: After determining the model and molecular weight, we can determine the amount of polyacrylamide to be used to treat sewage through actual small tests. > In the actual application process, choosing a suitable polyacrylamide product is the most concerned issue for users. When choosing polyacrylamide, we need to understand the electrical properties, molecular weight, charge density and solubility of polyacrylamide, etc. These important properties of polyacrylamide are also important properties that can be selected and observed or detected in polyacrylamide products. These properties not only affect the use effects and application methods of polyacrylamide, but are also important factors in determining the production cost of polyacrylamide.
