Scale and Corrosion Inhibitor (for Low Hardness Water)
Properties:
XT-682 is composed of surfactant, dispersant, corrosion inhibitor, etc. It is suitable for systems that adopt soften water and other low hardness water as cool media. Because of low content of Ca2 and Mg2 ions in soften water, scale cannot be formed. Many corrosion inhibitors use Ca2 and Mg2 ions in water to form protection membrane on metal surface. Due to the low content of Ca2 and Mg2 ions in soften water, the corrosion inhibition is difficult for soften water system. On the basis of a large number of experiments, we develop this environment-friendly scale and corrosion inhibitor for soften water system. XT-682 is a composite corrosion inhibitor which works by inhibiting the polarization of metal. XT-682 doesn’t contain such noxious subjects as nitrite and chromate. It doesn’t pollute the environment. Its corrosion rate to carbon steel is far lower than that of national standard.
