2022 высокое качество низкая цена гексаметафосфат натрия с

        

traits: white powder crystal, or colorless transparent glass flake or block solid.
Density (g / mL, 25 ° C): 2.5.

Melting point (decomposition, ºC): 616.
Solubility: soluble in water, insoluble in organic solvents. The aqueous solution is alkaline. Strong hygroscopicity, exposed to the air can gradually absorb moisture and viscous material. And calcium, magnesium and other metal ions can generate soluble complexes.

1, mainly used in food and industrial sectors. Which food industry applications are:
 a,   Sodium hexametaphosphate for meat products, fish sausage, ham, etc., can increase water holding capacity, increase the junction sex, to prevent fat oxidation;
b,    For bean paste, soy sauce to prevent discoloration, increase the viscosity, shorten the fermentation period, regulate the taste;
c,   For fruit drinks, soft drinks, can increase the rate of juice, increased viscosity, inhibition of vitamin C decomposition;
d,   For ice cream can increase the expansion capacity, increase the volume and enhance the role of emulsion to prevent paste damage, improve the taste and color;
e,   For dairy products, beverages prevent gel precipitation;
Add beer to clarify the wine, to prevent muddy;
f,   For beans, canned fruits and vegetables, can stabilize natural pigments, protect food color;
Sodium hexametaphosphate aqueous spray coating on pickled meat, can improve the anti-corrosion properties.

 2, mainly in the industrial sector:
Sodium hexametaphosphate and sodium fluoride can be heated to produce monofluorophosphate, which is an important industrial raw materials;
Sodium hexametaphosphate as a water softener, such as used in dyeing and finishing, play a role of water softener;  also used as a scale inhibitor widely used in EDI (resin electrodialysis), RO (reverse osmosis), NF (nanofiltration) and other water treatment industry.
