Sodium Hexa Meta Phosphate (SHMP)
1)Name: Sodium
Hexametaphosphate SHMP
2)Molecular formula: (NaPO3)6
3)Molecular weight: **1.*2
4)Physical and Chemical property: It is white crystal powder.
Specific gravity is 2.**4 at *0ºC. Melting point is **6ºC. Soluble
in water easily, but not in organic solvent; Strong hygroscopicity,
glue-like while absorbing water in the air, combined with metal
ions, such as Ca, Ba, Mg, Cu, Fe and so on to form soluble
chelates. It is an excellent water treatment agent.
1.Use:For tech grade, mainly
used as water conditioner, buffer, floating agent, dispersant, high
temperature bonding agent in the industry of oil field, paper
making, textile, printing and dyeing, petroleum, chemicals,
leather, metallurgy, building; For food grade, used as additives,
Nutrition, quality improver, PH value adjustment agent, metal ion
chelating agent, binder, expansion agent.
2.Packaging and
Storage:Plastic knit bag and two-tier inside. It is stored
in ventilated and dry place.
Net weight : *5Kg or *0 Kg. or as customer's
request
