Description

TH***2 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.TH***2 is a composite corrosion inhibitor by inhibition of metal polarization. TH***2 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.
