Embodiment Construction
[0014] The embodiments of the present invention are further described in detail below.
[0015] The invention provides a new corrosion and scale inhibitor, characterized in that the new corrosion and scale inhibitor consists of the following weight ratio:
[0016] Sodium polyepoxysuccinate: 1-16; Sodium polyaspartate: 1-18;
[0017] Hydrolyzed maleic anhydride: 1-13; Sodium gluconate: 1-25;
[0018] Acrylic acid-acrylate-sulfonate terpolymer: 1-18;
[0019] Zinc sulfate: 1-8; Benzotriazole: 1-12;
[0020] NaOH: 0.5-2.
[0021] Polyepoxy sodium succinate (PESA) in the present invention: is a kind of non-phosphorus, non-nitrogen "green" environment-friendly multiple scale and corrosion inhibitors, calcium sulfate, barium sulfate, calcium fluoride and silicon scale have good Anti-scaling and dispersing properties. PESA has good biodegradability and a wide range of applications, especially for cooling water systems under the conditions of high alkali, high hardness, high pH a...
