Properties:
TH-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.
TH-682
is a composite corrosion inhibitor by inhibition of metal polarization.
TH-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.
