Embodiment 1
[0018] Salt-making antiscaling agent, the mass percentages of effective components of each substance are: 5% of 1,6-hexamethylenetriaminepentamethylenephosphonic acid, 8% of diethylenetriaminepentamethylenephosphonic acid heptasodium salt, carboxylic acid Salt-sulfonate-nonionic terpolymer 2%, phosphonocarboxylic acid copolymer 2%, sodium polyacrylate 12%, caustic soda 2.8%, deionized water 68.2%.
[0019] Among them, the carboxylate-sulfonate-nonionic terpolymer is composed of monomer acrylic acid, 2-acrylamide-2-methylpropanesulfonic acid and hydroxypropyl acrylate in a mass ratio of 12.5:6:1 at 90 It is prepared by polymerization at ℃, and the viscosity-average molecular weight is 4300.
[0020] The antiscalant was applied to a salt field in Huainan, and the system could continue to operate for more than 10 months when used at a concentration of 20mg / L, and the antiscalant effect was obvious.
Embodiment 2
[0022] Salt-making antiscaling agent, the mass percentages of effective components of each substance are: 7% of 1,6-hexamethylenetriaminepentamethylenephosphonic acid, 5% of heptasodium diethylenetriaminepentamethylenephosphonic acid, 5% of ethylene diaminepentamethylenephosphonic acid Sodium amine tetramethylene phosphonate 7%, phosphonocarboxylic acid copolymer 5%, hydrolyzed polymaleic anhydride 5%, caustic soda 6%, deionized water 65%.
[0023] The antiscalant was applied to a salt field in Henan, and the system could continue to operate for more than 10 months when used at a concentration of 20mg / L, and the antiscalant effect was obvious.
Embodiment 3
[0025] Salt-making antiscaling agent, the mass percentages of effective components of each substance are: 7% of 1,6-hexamethylenetriaminepentamethylenephosphonic acid, 4% of diethylenetriaminepentamethylenephosphonic acid, butyl 2-phosphonate Alkane-1,2,4-tricarboxylic acid 4%, carboxylate-sulfonate-nonionic terpolymer 5%, phosphonocarboxylic acid copolymer 4%, hydrolyzed polymaleic anhydride 3%, polyacrylic acid 4%, deionized water 69%.
[0026] Among them, carboxylate-sulfonate-nonionic terpolymer is composed of monomer acrylic acid, 2-acrylamide-2-methylpropanesulfonic acid and hydroxypropyl acrylate in a mass ratio of 12.5:6:1 at 95 It is prepared by polymerization at ℃, and the viscosity-average molecular weight is 3800.
[0027] The antiscalant was applied to a salt field in Ningxia, and the system could continue to operate for more than 10 months when used at a concentration of 20mg / L, and the antiscalant effect was obvious.
