ABSTRACT:
The prevention of corrosion on the surfaces of airwasher systems and particularly systems containing low levels of hardness is controlled utilizing a corrosion inhibiting amount of a composition including an alkali metal silicate, a hydroxycarboxylic acid or its water soluble salts, a polyacrylate or its water soluble salts, and a water soluble polymer which acts as a dispersant. Superior corrosion inhibition is achieved using the compositions of this invention as corrosion inhibitors, particularly in industrial airwasher systems employing mild steel metallurgy.
