Example Embodiment
[0018] Example 1
[0019] A scale inhibitor and dispersant for water treatment, calculated in parts by weight, including the following raw materials:
[0020] 60 parts of maleic anhydride, 26 parts of allyl sulfonic acid, 9 parts of aspartic acid, 24 parts of ethyl acrylate, 26 parts of mannonic acid, 11 parts of initiator, and 170 parts of water. The initiator is a mixture of ammonium persulfate and sodium bisulfite. The mass ratio of ammonium persulfate to the sodium bisulfite is 3:1.
[0021] The preparation method of water treatment scale inhibitor dispersant includes the following steps:
[0022] 1) Weigh maleic anhydride, allyl sulfonic acid, ethyl acrylate, mannonic acid, initiator, and water according to the ratio, and mix the maleic anhydride with part of the water and then stir to dissolve to obtain an aqueous solution of maleic anhydride;
[0023] 2) The initiator is dissolved in a small part of water to prepare an initiator aqueous solution;
[0024] 3) Raise the maleic anh...

The initiator is a mixture of ammonium persulfate and sodium bisulfite. The mass ratio of ammonium persulfate to the sodium bisulfite is 2:1.
[0035] The preparation method of water treatment scale inhibitor dispersant includes the following steps:
[0036] 1) Weigh maleic anhydride, allyl sulfonic acid, aspartic acid, ethyl acrylate, mannonic acid, initiator, and water according to the ratio. First, mix maleic anhydride with part of the water and stir to dissolve to obtain Maleic anhydride aqueous solution;
[0037] 2) The initiator is dissolved in a small part of water to prepare an initiator aqueous solution;
[0038] 3) The maleic anhyd...
