Polymeric scale inhibitors include homopolymers and copolymers

① After the chelating and solubilizing copolymer scale inhibitor is dissolved in water, groups such as carboxyl group, hydroxyl group and phosphoric acid group can dissociate hydrogen ions, turning them into negatively charged anions.

②The effect of lattice distortion during the growth of calcium carbonate crystallites, when scale inhibitors are added, they will adsorb to the active growth point of calcium carbonate crystals and integrate with Ca ²⁺ , inhibiting the growth of the crystal lattice in a certain direction, and make the crystals grow in a certain direction.

③Condensation and subsequent dispersion.

As a water treatment agent, copolymer scale inhibitors have the advantages of a wide range of varieties, mature synthesis methods, wide applicable water quality range, low toxicity and no pollution, etc.
