Introduction to the production process of polyacrylamide


Introduction to the production process of polyacrylamide
Polyacrylamide is a commonly used inorganic polymer flocculant, which is widely used in China's municipal sewage treatment, tap water, industrial sewage purification and other fields. In terms of comprehensive comparison, polyacrylamide has the characteristics of strong adaptability, ideal treatment effect and low comprehensive cost, so it is favored by various fields of water treatment. Everyone knows the conventional physical and chemical properties of polyacrylamide, so how much do you know about the production process of polyacrylamide?
Polyacrylamide is divided into anionic, cationic, non-ionic, zwitterion, etc. according to the ion type, although it is divided into four types, but the actual polyacrylamide production process is basically the same, Jiaxin water purification for polyacrylamide production to make a brief introduction.
Simply summarized as: acrylonitrile (the most important raw material of polyacrylamide) + (water catalyst and water) → polymerization → crude acrylamide products→ flash drying → refined → polyacrylamide finished products. To be precise, the production process of polyacrylamide is based on acrylonitrile as raw material, adding initiator or catalyst, polymerization reaction as acrylamide aqueous solution, and then dried to make a finished product, adding different charge ions in the drying process, so as to produce polyacrylamide of different ion models.
