Sodium hexametaphosphate (10124-56-8)
|
appearance, sodium hempetaphosphate presents transparent glass flakes or white granular crystals, with a
relative density of 2.484 g/cm³ (20ºC), easily soluble in water, but insoluble in organic solvents. It is worth
noting that it has a strong hygroscopicity, and will gradually absorb water when exposed to air, forming a
viscose substance. It can also form soluble complexes with calcium, magnesium and other metal ions.
 
:The preparation process of sodium hempetaphosphate is usually through the neutralization
reaction of soda ash or caustic sodasolution with , and then the sodium metaphosphate is
generated at 250 ° C, and then further heated to 620 ° Cto polymerize and form crystallization, and then the
flake or granular product is obtained after cooling.
For food-grade sodium hempetaphosphate, it needs to be purified by removing and heavy metals,
and then baked and prepared,which is mainly used for food quality improvement, chelating agents,
fermentation bulking agents and pH regulators.

In practical application, sodium hexametaphosphate as an excellent water treatment agent, it can promote hydration,
help to dispersethe sediment in the drink, make the drink more clear. At the same time, it also plays an important
role in metal surface treatment,cement hardening promotion, coated paper paste diffusion and oil drilling.
Package:25kg/bag, 500kg/1000kg /jumbo bag or as customers' requirements.
Storage: 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,
is should be stored separately from poisonous.
