Product name: Sodium Hexametaphosphate/ SHMP 68%
Formula: (NaPO3)6
CAS No.: 10124-56-8
F. W.: 611.77
Property: White powder, density is 2.484(20 degree C), easily soluble in water, but not on organic solution, absorbent to dampness, and furn sticken when absorbed dampness in air. It's 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
Storage: It should be stored in a ventilative and dry warehouse instead of in the open air, kept away from water, moisture and sunlight during transport, handled with care, so as to avoid damage to plastic bags. Furthermore, is should be stored separately from poisonous.
