Sodium henamephophate
name：Sodium henamephophate
Formula：（NaPO3）6
M.W：611.77
CAS NO.：10124-56-8
Characters：a type of sodium metaphosphate polymer, transparent glass flake or white powder crystal.Strong hygroscopicity;After moisture absorption and viscosity, it is easy to be wet in the air, soluble in water, and solubility in water is large, but the dissolution rate is slow.The aqueous solution is acidic.Hydrolysis or phosphates.Some metal ions (calcium and magnesium) have the ability to produce or dissolve complex complexes, so they can be used to soften water, and can also produce complex complexes with lead, silver and barium salts.
Usage：used for power stations, vehicles, and fertilizer plant cooling water treatment of boiler high efficiency water softener, detergent additives, control or anticorrosion agent, cement hardening accelerator, streptomycin purifying agent, fiber industry, bleaching and industrial cleaning agent.The mineral processing industry is used as flotation agent.It is used as an anti-rust for drilling pipe and to adjust the viscosity of the slurry during oil drilling.It is also used in textile printing and dyeing, tanning, paper making, color film, soil analysis, radiochemistry, analytical chemistry and so on.
