GT-682 Scale and Corrosion Inhibitor for


GT-682 is built with surfactant, dispersant, corrosion inhibitor, etc. It is suitable for system using soften water and other low hardness water as cool media. Because there are little contents of Ca2+ and Mg2+ ions in soften water, scale cannot be formed. Many corrosion inhibitors use Ca2+ and Mg2+ ions in water system to form protection membrane on metal surface, but there are little contents of Ca2+ and Mg2+ ions in soften water, the corrosion inhibition is a difficult question for soften water system. Through experiments, we develop this greenish scale and corrosion inhibitor for soften water system. GT-682 is a composite corrosion inhibitor by inhibition of metal polarization. GT-682 has no contents of such noxious subjects as nitrite and chromate, no pollution to environment, its corrosion ratio to carbon steel far lower than that of national standard.
