Sodium hexametaphosphate Calgon

Name synonyms: SODIUM POLYPHOSPHATE, salt Graham, SHMP

CAS no.: 10124-56-8, 68915-31-1

Chemical formula: (NaPO3)n•nH2O

HS CODE: 2835310000

PHYSICAL PROPERTIES: is a white powder, which is a chemical compound, or rather mixture hexametaphosphate salts of sodium and potassium in a certain ratio. It is also known under the name Calgon or M-19

APPLICATION: In food industry to improve the quality of food also acts as a regulator of PH.In leather manufacturing, rail and industrial power plants for water softening, in the oil industry for drilling wells.

Polyphosphate sodium is the most active sadomachism tool, because it forms stable complexes in a shorter time and at lower temperatures (20-40 ° C), than sodium tripolyphosphate (STPP plant) and other phosphates.

The advantage of sodium polyphosphate, trisodium phosphate before (TNF) is a higher content of phosphate in terms of P2O5 is more than 63 %. In comparison with SFI in TNF phosphates in terms of P2O5 does not exceed 25 %. Recommendations and regulations indicate that the application rate SFI 3-4 times less than that of TNF.

The advantages of SFI is lower caking during storage, anti-corrosion properties, ability to reduce iron-oxide and copper scale formation on the internal heating surfaces of boilers.

Chelating ability (the ability to form water-soluble complexes, which stability is over 1 year old) allows you to make SFI only once for the entire heating season. For comparison, the stability of the complexes of sodium tripolyphosphate is from 2 to 6 months, and trisodium phosphate even less.

Polyphosphate sodium phosphate is the most concentrated of commercially available phosphates.
The estimated savings when using the SFI is 6000-7000 rubles per ton consumption of TNF. When using tripolyphosphate cost is 900-1200 RUB/t.
Polyphosphate is a corrosion inhibitor. To prevent corrosion of the piping, especially in soft water, it is recommended to keep the contents of polyphosphate at the level of 2-3 kg / m3 of water or 0.2-0.3% of the weight of the flowing water and the pH=7-8.
Reduction of Sa deposits in pipelines, the application of SFI, prolongs the service life of boilers, prevents the decrease in heating efficiency of water heaters and pipeline throughput.
SFI can be used in individual heating of private buildings and requires a single application per heating season.
It should be noted that the polyphosphate is non-toxic and biodegradable
SAFETY REQUIREMENTS: Sodium polyphosphate technical fire - and explosion-proof, non-toxic.

TRANSPORT AND STORAGE: Sodium polyphosphate technical transporterowych rail, road and water transport in covered vehicles. By rail packaged products transporterowych carload shipments in covered wagons. Sodium polyphosphate technical stored in closed unheated warehouses.
