1.Chemical deoxidization for water supply . Its deoxidizingeffect is equial to hydrazine, while its toxicity is only 1/19 ofthat of hydrazine
2.maintenance of thermal engineering equipment during lay-off timeor reservation.Owing to its good quality of reduction ,its watersolution can form an effective magnetic oxide film on the surfaceof steel, thus effectively slowing down the corrosion of thermalengineering equipment during lay-off or reservation time
3. passivant function . this product can replace such toxicityreagents as sodium nitrite and hydrazine to serve as a fine-qualitypassivant film on thermal engineering equipment after it has beenpickled; and it will be free from pollution when beingexhausted.
