ZOW-682 is composed of surfactant, dispersant, corrosion inhibitor, etc. It can be applied to systems using soft water or other low hardness water as cool media. Because of the small content of Ca2+ and Mg2+ in soft water, scale cannot be formed. Many corrosion inhibitors use Ca2+ and Mg2+ in water system to form protecting membrane on metal surface, but there are few Ca2+ and Mg2+ in soft water, so it is difficult to inhibit the corrosion of soft water system. Through experiments, we developed this environment-friendly scale and corrosion inhibitor designeed for soft water system. It is a composite corrosion inhibitor by inhibition of metal polarization. ZOW-682 has no noxious substances such as nitrite or chromate and no pollution to environment. Its corrosion rate for carbon steel is far lower than national standard
Add ZOW-682 into plastic pool (or box) every day, dilute with water and continuously add into inlet of dosage pump or metering valve (outlet of collecting tank). The dosage of 30~70ppm is preferred.
