Sodium Molybdate, a white rhombic crystals. Can be generated by the roasting of molybdenum concentrate, molybdenum trioxide, molybdic acid leaching generate caustic soda solution, after filtration, concentration, cooling, centrifugation, drying can be obtained. For the manufacture of alkaloids, ink, fertilizers, molybdenum red pigment and light fastness pigment precipitation agent, catalyst, molybdenum salt can also be used to manufacture fire retardant and water system pollution-free type of metal inhibitors, also used as a galvanizing, polishing agents and chemical reagents.

 

Molybdate low toxicity, low pollution level of environmental pollution, is currently the more of a new water treatment agent. In order to obtain good release effect, molybdates often with polyphosphates, gluconate, zinc salts, benzotriazole compound used, so not only can reduce the amount of molybdate, but also improve the corrosion effect, the amount of post-molybdate complex by 200 ~ 500mg / L down to 4 ~ 6mg / L. Molybdate film forming process, the dissolved oxygen must be present without calcium (or other divalent metal ions). Molybdate high thermal stability and can be used for high heat flux and local

 

Sodium molybdate has low toxicity compounds. Molybdenum poisoning can cause joint pain, low blood pressure and cause fluctuations in blood pressure, neurological disorders, metabolic process obstacles. Soluble molybdenum compound aerosol maximum allowable concentration of 2mg / m, dust of 4mg / m. Handling and use of sodium molybdate, Wear the specified protective equipment. Pay attention to moisture. Transportation beware of rain, sun.
