| titleOfInvention | High-temperature-resistant scale inhibition and dispersion agent and preparation method thereof |
| abstract | The invention discloses a high-temperature-resistant scale-inhibiting dispersant and a preparation method thereof, wherein the high-temperature-resistant scale-inhibiting dispersant comprises the following raw materials in parts by weight: 15-25 parts of hyperbranched macromolecules, 23-47 parts of multipolymer, 10-15 parts of modified chitosan and 20-45 parts of deionized water; the hyperbranched macromolecule is organic phosphine hyperbranched macromolecule taking melamine as core; the multipolymer is prepared by copolymerizing amino acid, carboxylic anhydride and sulfonate. The invention prepares a high temperature resistant dirt dispersion agent which can be used for a multi-stage flash evaporation and seawater desalination system through hyperbranched macromolecules, multipolymer and modified chitosan; compared with the prior similar products, the high-temperature resistant scale inhibition dispersing agent prepared by the invention has excellent performance, is more prominent in the aspects of sulfate and silica scale inhibition, and realizes multi-effect evaporation and high-efficiency, energy-saving and stable operation of a seawater desalination system. |
