Sodium Hexametaphosphate (SHMP)TG
Chemical formula: (NaPO3)6
Molecular weight: 611.82
Properties
White powder, specific gravity is 2.484 (20°C), easily soluble in water, but not in organic solution, absorbent to dampness, and turn 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.
Applications
For industrial use, such as oil field, paper-making, textile, dyeing, petrochemical, tanning, metallurgical 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 and Storage
In 25kg, or big bags and store at a cool, dry and well ventilated place.
