Chemical formula :(NaPO
3)
6
Molecular weight:611.82
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.
Uses:
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.
Packing and storage:
