Product Description

Sodium Hexametaphosphate/SHMP 68%
 

1.General Information of Sodium Hexametaphosphate/SHMP 68%
Chemical formula: (NaPO3)6 
Other name: Graham Salt
Standard executed: HG/T2837-1997 
Molecular weight: 611.82 
CAS No.: 10124-56-8
White powder, density is 2.484 (20ºC), 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.

 

2.Introduction of Sodium hexametaphosphate
Sodium hexametaphosphate is a glass phosphate with a molecular ratio of nearly 1 NA2O/P2O5. The past is called "Graham" salt. In 1832 by Graham found. He will dehydrate and the sodium dihydrogen phosphate salt, at the melting point (625 C) under heating, and the melt is rapidly cooled, and prepared hygroscopic Graham salt.

3.Performance characteristics of Sodium hexametaphosphate
A partial sodium phosphate polymer, transparent glass flake or white powder crystal. The hygroscopicity is strong; after the moisture absorption becomes sticky, is easy to be moist in the air, is soluble in the water, in the water solubility is bigger, but the dissolution speed is slow; the aqueous solution assumes the acidic reaction. Easy hydrolysis or phosphite. For some metal ions (calcium, magnesium) have the ability to produce or dissolve complex, it can be used to soften water, and lead, silver, barium salt can also be complex.

5.Uses of Sodium hexametaphosphate
1)SHMP is used as a sequestrant and has applications within a wide variety of industries, including as a food additive. 
2)A significant use for sodium hexametaphosphate is as a deflocculant in the production of clay-based ceramic particles.
3)It is also used as a dispersing agent to break down clay and other soil types.
4) It is used as an active ingredient in toothpastes as an anti-staining and tartar prevention ingredient.




6.Package and Storage conditions of Sodium hexametaphosphate
25kg in plastic woven bag with polythene liner and stored in a ventilated, dry warehouse, and need to pad cushion, pay attention to rain, moisture, sun protection. Avoid mixing, mixing, or mixing with toxic, harmful, corrosive, volatile or odorous items. Pants should be dust, rodent control, anti-fly measures to avoid pollution. After the use of products opened in time to seal, to prevent the product damp and agglomeration.



7.Safety warning 
Operation is to pay attention to ventilation, should be a few vehicles to reduce dust, it is recommended that operators wear dust masks, protective gloves, the need to wear chemical safety glasses.
