| 摘要 |
The invention relates to a method of controlling silica scale in an aqueous system, including adding an effective amount of mixture of a first polymer and a second polymer into the aqueous system, wherein the first polymer and the second polymer each has at least one of a first structural unit derived from any of quaternary ammonium monomer, quaternary phosphonium monomer, and quaternary sulfonium monomer and a second structural unit derived from any of sulfonic acid, sulfuric acid, phosphoric acid, carboxylic acid and any salt thereof, the first polymer bears a first net charge or being neutral, the second polymer bears a second net charge opposite the first net charge or bearing positive net charge when the first polymer is neutral, the first structural unit is from about 1 mol % to about 99 mol % of the mixture. |
