DESCRIPTION: Sodium hexametaphosphate is a glassy transparent or white powder, hygroscopic - it has good adsorption and dispersing properties in air.
properties, used as a wetting agent in paints and varnishes, plasters and putties
Sodium hexametaphosphate is a free-flowing white or slightly greenish powder. Differs in good solubility in water and the ability to form soluble complexes with calcium, magnesium, barium and other metals, and also forms a crystalline hydrate of the composition Na6P6O18 • 6H2O. It is the most concentrated phosphate commercially available. Possesses good adsorption and dispersing properties.

Sodium hexametaphosphate-SHMP is used in industries, oil fields, papermaking, textiles, painting, petroleum, chemistry, metallurgy and building materials
etc., for water softening, flotation agent selection, dispersant and high temperature adhesive; In the food industry, sodium hexametaphosphate (SHMP) is used as an additive,
nutrient, quality improver, pH regulator, metal ions chelating agent, adhesives and baking powder, etc.
Application:
in industrial water softening systems as the most active water softener with high chelating ability, i.e. forms stable complexes in a shorter time and at lower temperatures (20-40 ° C) than sodium tripolyphosphate and other phosphates. The advantages also include lower caking during storage, anti-corrosion properties, the ability to reduce iron oxide and copper scale formation on the internal heating surfaces of boilers. The use of sodium polyphosphate allows to increase the service life of pipelines and filters due to its anti-corrosion properties;
in the chemical industry, as a salt inhibitor, as a component of detergents (for example Calgon);
in the textile industry, to prevent the formation of calcium salts on fabrics;
in the oil industry, in drill technological processes;
ceramics industry as a softener and dilution of wells when filtering slurries and solutions;
in the pulp and paper industry, it is involved in a variety of papermaking processes.

CAS: 10124-56-8, 68915-31-1
Chemical formula: (NaPO3) n • nH2O
TNVED CODE: 2835310000
PHYSICAL PROPERTIES: it is a white powder, which is a chemical compound, or rather a mixture of sodium and potassium hexametaphosphoric acid salts in a certain ratio. It is also known as Kalgona or M-19
APPLICATIONS: In the food industry to improve the quality of food, it also acts as a pH regulator in the leather industry, in railway and industrial power plants for water softening, in the oil industry for drilling wells.
Sodium polyphosphate is the most active water softener because forms stable complexes in a shorter time and at lower temperatures (20-40 ° C) than sodium tripolyphosphate (TPPN) and other phosphates.
The advantage of sodium polyphosphate over trisodium phosphate (TNP) is a higher phosphate content in terms of P2O5 - more than 63%. Compared to PFN in TNF, the phosphate content in terms of P2O5 does not exceed 25%. Recommendations and regulatory documents indicate that the rates of PFN application are 3-4 times less than that of TNF.
The advantages of PFN also include lower caking during storage, anti-corrosion properties, the ability to reduce iron oxide and copper scale formation on the internal heating surfaces of boilers.
The chelating ability (the ability to form water-soluble complexes, the stability of which is more than 1 year) allows PFN to be added only once during the entire heating season. For comparison: the stability of sodium tripolyphosphate complexes is from 2 to 6 months, and trisodium phosphate is even less.
Sodium polyphosphate is the most concentrated phosphate commercially available.
Estimated savings when using PFN is 6000-7000 rubles per ton of consumed FSP. When using tripolyphosphate, the savings are 900-1200 rubles / ton.
Polyphosphate is a corrosion inhibitor. To prevent pipeline corrosion, especially in soft water conditions, it is recommended to maintain the polyphosphate content at a level of 2-3 kg / m3 of water or 0.2-0.3% of the weight of running water and pH = 7-8.
A decrease in Ca deposits in pipelines, when using PFN, prolongs the life of boilers, prevents a decrease in the heat output of water heaters and the throughput of pipelines.
PFN can be used in individual heat supply of private buildings and requires a single application during the heating season.
It should be noted that polyphosphate is non-toxic and biodegradable
