Description
Chemical formula: (NaPO3)6
Molecular weight: *****2
Properties:
White powder, density is 2.**4(*0), 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:
*5kgs net paper bags or *5kgs net plastic woven bags
Storage and transport:
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, it should be stored separately from poisonous
substances.
