Embodiment 1
[0015] Example 1: Weigh 40 parts of sodium chloride, 2 parts of sodium dodecylbenzenesulfonate, 0.6 part of fatty acid methyl ester ethoxylate, 0.4 part of fatty acid, and 7 parts of polyethylene glycol. After mixing evenly according to the above weight parts, take a certain amount of new additive and dissolve it in the aqueous solution to prepare an additive solution with a mass fraction of 0.03%. Magnetized water, measured its surface tension, contact angle.
Embodiment 2
[0016] Example 2: Weigh 40 parts of sodium chloride, 2.5 parts of sodium dodecylbenzenesulfonate, 1 part of fatty acid methyl ester ethoxylate, 0.4 parts of fatty acid, and 7 parts of polyethylene glycol. After mixing evenly according to the above weight parts, take a certain amount of new additive and dissolve it in the aqueous solution to prepare an additive solution with a mass fraction of 0.03%. Magnetized water, measured its surface tension, contact angle.
Embodiment 3
[0017] Example 3: Weigh 35 parts of sodium chloride, 2 parts of sodium dodecylbenzenesulfonate, 0.6 part of fatty acid methyl ester ethoxylate, 0.5 part of fatty acid, and 8 parts of polyethylene glycol. After mixing evenly according to the above weight parts, take a certain amount of new additive and dissolve it in the aqueous solution to prepare an additive solution with a mass fraction of 0.03%. Magnetized water, measured its surface tension, contact angle.
