1.Chemical deoxidant for water supply.Deoxygenation effect is same as that of hydrazine,but the toxicity is 1/19 of that of hydrazine.2.Protectant for thermal equipment shutdown(standby).Due to the excellent reductibility the product has,its aqueous solution can provide the surface of steel with good magnetic oxide film,which can defer the corrosion of thermal equipment when it's shutdown(standby).3.Inactivation This product can substitute for toxic reagent-sodium nitrite and hydrazine to be used as the passivant for thermal equipment after acid cleaning.The film is of high quality and there is no pollution discharge.
