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.
