Acid resistance of different types of polyacrylamide

Polyacrylamide is widely used as an organic polymer flocculant. There are three ionic types of polyacrylamide: anionic, cationic and non-ionic, and each ionic type of polyacrylamide has different acid resistance. When we do sewage test, we must first test the PH value of sewage and choose the appropriate polyacrylamide model. Henan Xinhuan Water Treatment Materials Co., Ltd. is a manufacturer of production and sales of polyacrylamide, we analyze the acid resistance of polyacrylamide for our customers. Anionic polyacrylamide is the most commonly used model, which is suitable for a wide range of water conditions. However, its stability is compromised in acidic environments. As the acidity increases, the solubility of anionic polyacrylamide decreases, which affects its flocculation effect. Therefore, in strongly acidic conditions, it is necessary to select a more acid-resistant polyacrylamide model. Cationic polyacrylamide has better acid resistance and is suitable for treating acidic wastewater. In an acidic environment, cationic polyacrylamide can provide positively charged groups to form stable flocs with suspended solids in negatively charged wastewater. In addition, the higher molecular weight of cationic polyacrylamide gives it better stability under acidic conditions. Nonionic polyacrylamide has excellent acid resistance and is suitable for treating highly acidic and highly concentrated wastewater. In an acidic environment, nonionic polyacrylamide does not carry any electrical groups, so its stability is higher. In addition, the higher molecular weight of nonionic polyacrylamide improves its solubility and stability under acidic conditions. In different acidic environments, we need to choose the appropriate polyacrylamide. When dealing with acidic wastewater, we need to choose cationic polyacrylamide or nonionic polyacrylamide with better acid resistance. Of course, in the actual use of the process, we also need to conduct a glass test.
