Example Embodiment
[0027] Example one:
[0028] Prepare 100g of phosphorus-free corrosion and scale inhibitor solution: add 7.5g of sodium gluconate, 11.05g of zinc sulfate, and 2.05g of rare earth metal salts to 58.45g of water, stir well, and then add 10g of polyepoxysuccinic acid for scale inhibition and dispersion 10.7g of agent, stir evenly, finally add 0.25g of benzotriazole, stir until fully dissolved, and filter to obtain.
[0029] Use the prepared 100g of the phosphorus-free corrosion and scale inhibitor solution and add it to the industrial water to be treated at a concentration of 300mg / L.
Example Embodiment
[0030] Embodiment two:
