Embodiment 1
[0022] Example 1: N 2 Under the atmosphere, take 78g sodium epoxysuccinate and dissolve in 160g deionized water, add 4.5g urethanesulfonic acid at room temperature, mix well, add dropwise NaOH solution with a concentration of 50% to adjust the pH value to 11.0, add 3.1g Ca ( Oh) 2The powder was heated to 90° C., polymerized for 3 hours, cooled to room temperature, and filtered to obtain a viscous yellow sulfonate amine polyepoxysuccinate liquid. The sulfonate amine-based polyepoxysuccinate liquid was exchanged with a polystyrene-based hydrogen-type cation exchange resin with an ion exchange capacity of 300 mmol / 100 g at room temperature for 1 hour to obtain a sulfonate amine-based polyepoxysuccinic acid liquid.
[0023] The scale inhibition performance results of sulfonate amine polyepoxysuccinic acid show that: when the addition amount of sulfonate amine polyepoxysuccinic acid is 30ppm, the scale inhibition rate of calcium carbonate scale can reach 94.3%, and the scale inhib...
Embodiment 2
[0024] Example 2: N 2 Under the atmosphere, weigh 74g of ammonium epoxysuccinate and dissolve it in 160g of deionized water, add 4.9g of sulfamic acid at room temperature, mix well, add dropwise the concentration of 40% NH 3 ·H 2 The pH of the O solution was adjusted to 10.0, 4.5 g of CaO powder was added, the temperature was raised to 90° C., and after polymerization for 2.5 hours, the solution was cooled to room temperature and filtered to obtain a viscous yellow sulfonate amine polyepoxysuccinate liquid.
[0025] The results of scale inhibition performance of sulfonate amine polyepoxysuccinate show that: when the addition amount of sulfonate amine polyepoxysuccinate is 30ppm, the scale inhibition rate to calcium carbonate scale can reach 91.2%, and the scale inhibition rate to sulfuric acid The scale inhibition rate of strontium scale can reach 89.9%; when the addition amount of sulfonate amine polyepoxy succinate is 3ppm, the scale inhibition rate of calcium sulfate scale...
Embodiment 3
[0026] Example 3: N 2 Under the atmosphere, weigh 78g of sodium epoxysuccinate and dissolve it in 160g of deionized water, add 4.5g of urethanesulfonic acid at room temperature, mix well, add dropwise NaOH solution with a concentration of 50% to adjust the pH value to 10.0, add 2.5g of NaOH solid , heated to 90° C., polymerized for 3 hours, cooled to room temperature, and filtered to obtain viscous yellow sulfonate amine polyepoxysuccinate liquid.
[0027] The results of scale inhibition performance of sulfonate amine polyepoxysuccinate show that: when the addition amount of sulfonate amine polyepoxysuccinate is 30ppm, the scale inhibition rate to calcium carbonate scale can reach 92.5%. The scale inhibition rate of strontium scale can reach 90.8%; when the addition amount of sulfonate amine polyepoxy succinate is 3ppm, the scale inhibition rate of calcium sulfate scale can reach 95.6%; When the addition of succinate is 6ppm, the scale inhibition rate to barium sulfate scale ...
