A kind of cationic polyacrylamide particle and preparation method thereof |
| abstract |
The invention relates to a cationic polyacrylamide particle and a preparation method thereof. The preparation method includes a step of polymerizing acrylamide and a cationic monomer to form a cationic polyacrylamide, and a step of preparing the cationic polyacrylamide formed by the reaction into cationic polyacrylamide particles, wherein the polymerization reaction Bicarbonate is added to the system of the polymer, and carbon dioxide gas is introduced into the polymerization reaction and the pressure is kept higher than atmospheric pressure and lower than 1.1MPa, and the cationic polyacrylamide is mixed with an organic acid to make the The cationic polyacrylamide particles described. The cationic polyacrylamide particles obtained by the invention can be rapidly dissolved at low temperature, and are often used in flocculants. |
