SODIUM HEXAMETA PHOSPHATE (FOOD GRADE)
Chemical formula: (NaPO3)6
Molecular weight: 611082
Properties:
White powder ,density is 2.484(20 ),easily
soluble in water, but not on organic solution, absorbent to dampness,
and furn sticky when absorbed dampness in air. It is possible to
form solvent compound with metallic ions such as Ca, Ba, Mg, Cu
and Fe; it is a fine agent for water treatment.
Application:
For industrial use, such as oil field, paper-making,
textile, dyeing, petrochemical industry, tanning industry, metallurgical
industry and building material industry, it is mainly used as a
water softening agent in solution for printing, dyeing, and boiler;
Diffusant in papermaking; slow corrodent, floating agent, dispersing
medium, high temperature agglomerant, detergent and soil analytical
chemistry reagent. For food grade, it is mainly used as additive
agent , PH adjusting agent and fermentation agent, and nourishment.
Packing:
25kgs net paper bags or 25kgs net plastic woven bags
