Embodiment 1
[0033] A kind of environment-friendly slow-release polymer antiscalant, its preparation method comprises the steps:
[0034] 1) Mix the antiscalant component (carboxymethyl inulin), carrier material (polyvinyl alcohol) and additives evenly, wherein the mass percentage of each component is: carboxymethyl inulin 38%, carrier material 61%, Additive 1%; Stir fully at room temperature to mix evenly, pour the mixture into the mold and pressurize to 10MPa, hold the pressure for 20min, open the mold to eject the block preparation and dry it;
[0035] 2) Prepare sodium alginate solution with a mass concentration of 3% and polyvinyl alcohol solution with a mass concentration of 6% respectively, mix the sodium alginate solution and polyvinyl alcohol solution at a volume ratio of 2:1, and mechanically stir in an environment at 40°C Mix for 30 minutes to form a stable uniform emulsion for use as a polymer wall material solution, prepare a hydrogen chloride solution (hydrochloric acid solut...
Embodiment 2
[0038] An environmentally friendly slow-release polymer scale inhibitor, its preparation method comprises the following specific steps:
[0039] 1) Mix the anti-scaling component (carboxymethyl inulin and polyepoxysuccinic acid powder), carrier material (polyvinyl alcohol) and additives evenly, and the mass percentage of each component is: carboxymethyl inulin 25 %, polyepoxysuccinic acid powder 25%, the amount of carrier material 49.5%, the amount of additives 0.5%; fully stir at room temperature to make it evenly mixed, pour the mixture into the mold and pressurize to 20MPa, hold the pressure for 15min and then open The block preparation is ejected from the mold and dried;
[0040] 2) Prepare sodium alginate solution with a mass concentration of 3%, a polyvinyl alcohol solution with a mass concentration of 6%, and a gelatin solution with a mass concentration of 5%, and mix the sodium alginate solution, gelatin solution, and polyvinyl alcohol solution by volume ratio 2:1:1 m...
Embodiment 3
[0043] An environmentally friendly slow-release polymer scale inhibitor, its preparation method comprises the following specific steps:
[0044] 1) Mix the antiscaling components (carboxymethyl inulin, polyaspartic acid powder), carrier material (polyvinyl alcohol) and additives evenly, wherein carboxymethyl inulin is 20% by mass, polyaspartic acid Acid powder 25%, carrier material dosage 54.5%, additive dosage 0.5%, fully stir at room temperature to make it evenly mixed, pour the mixture into the mold and pressurize to 10MPa, hold the pressure for 20min, open the mold and eject the block preparation and drying;
