1. Chemical formula: NaPO3
2. Properties:
White powder; Density 2.484(20); Soluble in water but insoluble in organic solvent; It has got strong hygroscopicity and can absorb humidity from the air to become into pasty form; It may form soluble chelates with ions of Ca, Ba, Mg, Cu, Fe etc. And is a good water treatment chemical.
3. Application:
Used in industries of oil fields, paper production, textile, dyeing, petroleum, chemistry, metallurgy and construction materials etc. As water softener, flotation selecting agent, disperser and high temperature adhesive; In food industry it used as an additive, nourishing agent, quality improver, pH regulator, metal ions chelating agent, adhesive and leavening agent etc.
