Description

technical field [0001] The invention relates to the technical field of polymer polymerization, in particular to a polyacrylamide polymerization reactor and a control method thereof. Background technique [0002] Polyacrylamide (PAM) is a linear polymer, and its products are mainly divided into two forms: dry powder and colloid. According to its average molecular weight, it can be divided into three categories: low molecular weight (<1 million), medium molecular weight (2 million to 4 million) and high molecular weight (>7 million). According to its structure, it can be divided into non-ionic, anionic and cationic. The anionic type is mostly the hydrolysis of PAM (HPAM). The main chain of polyacrylamide has a large number of amide groups, which has high chemical activity and can be modified to produce many derivatives of polyacrylamide. The products have been widely used in papermaking, mineral processing, oil extraction, metallurgy, building materials, sewage treatme...
