| titleOfInvention | A production process for preparing amphoteric polyacrylamide by using gamma rays to initiate polymerization |
| abstract | The invention discloses a production process for preparing amphoteric polyacrylamide by using gamma rays to initiate polymerization, which relates to the technical field of chemical raw material preparation. The specific technological process is as follows: adding water, acrylamide, cationic monomers, and anionic monomers in sequence in the container, and then adding a molecular weight regulator, stirring the various raw materials in the solution to form a mixed solution; adjusting the pH with an alkali is 5-9 , to obtain the preparative material; the preparatory material is stirred evenly and then placed in a 60 Co-γ ray radiation field to carry out a radiation-initiated polymerization reaction with a radiation dose of 0.2KGy to 30KGy, and the zwitterionic polyacrylamide is obtained after the polymerization reaction is completed. The reaction process of this process does not require heating, and the amphoteric polyacrylamide is synthesized under normal temperature and normal pressure conditions. The equipment utilization rate is high, the process is simple, and the use of chemical initiators is avoided, the monomer conversion rate is high, and the production safety and environmental protection are more. Well, it has a good prospect of industrial application. |
