Seawater corrosion inhibitor applied to carbon steel and application method thereof

The invention provides a seawater corrosion inhibitor applied to carbon steel. The seawater corrosion inhibitor is characterized by being prepared from the following components in percentage by mass: 2-10% of polyaspartic acid, 2-8% of sodium gluconate, 3-5% of molybdate, 4-8% of zinc sulfate and th...

Beschreibung
Zusammenfassung:	The invention provides a seawater corrosion inhibitor applied to carbon steel. The seawater corrosion inhibitor is characterized by being prepared from the following components in percentage by mass: 2-10% of polyaspartic acid, 2-8% of sodium gluconate, 3-5% of molybdate, 4-8% of zinc sulfate and the balance being water. The seawater corrosion inhibitor applied to carbon steel has high inhibition effect on the corrosion of the carbon steel in the seawater, is excellent in inhibition lasting effect, low in cost and strong in practicability, and is environmentally friendly.
