摘要

PROBLEM TO BE SOLVED: To provide a metal corrosion inhibitor for water systems that exhibits excellent anticorrosive effect by the addition of a small amount of it and is highly safe, and a corrosion inhibition method for water systems using the same.;SOLUTION: A metal corrosion inhibitor for water systems contains (i) at least one anticorrosive component selected from phosphoric acid and polymerized phosphoric acid, and salt thereof, and (ii) at least one anticorrosive component selected from nicotinic acid and nicotinic acid amide, in such a proportion as to exhibit synergistic anticorrosive effect.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
