Sodium hexametaphosphate

CAS number : 10124-56-8

Molecular weight :

Molecular formula/chemical symbol :(NaPO2)

Description :
 

Transparent glass flake or white powder crystal, polymeric sodium metaphosphate body a strong hygroscopic; moisture and become sticky, humid air easily soluble in water, a greater solubility in water, but slower dissolution; aqueous acidic reaction. Easily hydrolyzed or phosphite. Certain metal ions (calcium, magnesium), the ability to generate or insoluble complexes, and therefore can be used to demineralized water, and lead, silver, barium salt, etc. can also generate complex.

USES :

As power stations, locomotive vehicles, boilers and fertilizer plant cooling water efficient water softener, detergent additives, control or anti-corrosion agents, cement hardening accelerator, streptomycin purification agent, textile industry, dyeing industrial cleaning agents. Used as a flotation agent in the mineral processing industry. Medicine used as a drilling pipe rust and control of oil drilling to adjust the viscosity of the slurry of the rose. Fabric printing and dyeing, tanning, paper, color film, soil analysis, radiation chemistry, analytical chemistry and other departments also have a certain purpose.

Mainly used for boiler water water softener, dyeing dye bath water softener and paper diffusion agent. Is also used for the corrosion inhibitors, flotation agents, dispersing agents, and the high temperature binding agent. The other for washing utensils as well as chemical fiber used to remove iron from the pulp. Also for soil analysis.
