Sodium molybdate dihydrate is sodium molybdate, which is also known as sodium molybdate dihydrate. Sodium molybdate is dihydrate.

Sodium molybdate is a new type of water treatment agent widely used at present. In order to obtain better corrosion inhibition effect, molybdate is often used in combination with polyphosphate, gluconate, zinc salt and benzotriazole, which can not only reduce the amount of molybdate used, but also improve the corrosion inhibition effect. The amount of molybdate reduced from 200 ~ 500mg / L to 4 ~ 6mg / L. In the process of molybdate film formation, there must be dissolved oxygen without calcium ion (or other divalent metal ions). Molybdate has high thermal stability and can be used in circulating water system with high heat flux and local overheating.

The high allowable concentration of soluble molybdate aerosol is 2 mg / M and that of dust is 4 mg / m. Pay attention to damp proof. It must be protected from rain and sun during transportation.

Uses: used as precipitant, catalyst and molybdenum salt of alkaloid, ink, fertilizer, molybdenum red pigment and light resistant pigment, as well as flame retardant and metal inhibitor of pollution-free cold water system, as well as zinc plating, polishing agent and chemical reagent.
