Character: It is white powder; Byname is Pent-sodium Phosphate; Melting point is 622°C;It has salient chelating capacity to ions of Ca, Mg etc; It can soften the hard water to make suspension become into the clear solution; it has weak alkalinity but no corrosiveness. It is a surfactant which has outstanding emulsification for lubricants and fat; It has different bulk density, i.e. low density 0.35-0.5g/cm3, medium density 0.51-0.65g/cm3 and high density 0.66-0.9g/cm3.This product has two kinds of crystalline forms, namely Type I (the type of high temperature) and Type II (the type of low temperature). The chemical characters of the two types are the same, and the difference between them lies in the thermo stability
Usage:
1.Used as one of the main auxiliaries for synthetic detergent, synergist for soap;
2.water softener, tanning agent for leather making, auxiliary for dyeing;
3.As an effective dispersion agent for suspension solutions of coatings, kaolin, magnesium oxide, calcium carbonate and drilling mud etc.;
4.As an oil contamination resistance agent in paper production.

| Sodium tripolyphosphate Usage And Synthesis |
| detergent builders |
Sodium tripolyphosphate is a kind of excellent detergent additives, the largest amount of detergent in the production process is set, its role has four aspects: 1. the effect of heavy metal ion chelate: heavy metal ions in the process of washing water, can combine detergent molecules to form insoluble metal salt,reduce the washing ability, even complete loss of function. Therefore, it is necessary to add chelating agent, which can make water containing heavy metal ions into harmless substancesin the detergent. Sodium tripolyphosphate has strong chelation for heavy metal ions, sealing them and eliminating the adverse effects on the washing. In addition, it can capture dirt contained various metals in washing process, playing the role of dissociation of dirt, used as soap synergist and preventing bar soap grease precipitation and bloom. 2. The dirt on his gum, emulsifying and dispersing effect: Dirt often contain body fluids (mainly protein and fat like substances), also contains the sand from the outside world, dust etc.. Sodium tripolyphosphate has the expansion, solubilization on dirt protein, and the effect of the glue solution; emulsification of fat promotes; has dispersing effect on solid dirt, strong emulsification of lubricating oil and fat, can be used to adjust the pH value of buffer liquid soap. 3. prevent caking of detergent: Synthetic detergent powder is hygroscopic, such as stored in high humidity areas, it is necessary to caking phenomenon. Using detergent agglomerates is inconvenient. While the water absorption of sodium tripolyphosphate formed the hexahydrate, with characteristics of dry. When there is extensive use of detergent formulations, it can serve to prevent caking phenomenon caused by moisture absorption, keeping dry granular of the synthetic detergent. 4. It has a larger buffer alkaline washing solution, pH value is maintained at about 9.4, which is conducive to the removal of acidic dirt. The above information is edited by the Chemicalbook Hayan. |
| chemical property | It is white powder, soluble in water, its water solution is alkaline. |
| Application |
1. It is used for meat processing, synthetic detergent formulations, textile dyeing, also used as dispersing agent, solvent etc. 2. It is used as soft water, also used in confectionery industry. 3. It is used as power stations, locomotive vehicle, boiler and a fertilizer plant cooling water treatment, water softener. It has strong ability to Ca2+ collaterals, per 100g to complex 19.5g calcium , and because SHMP chelation and adsorption dispersion destroyed the normal process of calcium phosphate crystal growth, it prevents the formation of calcium phosphate scale. Dosage is 0.5 mg / L, prevent that scaling rate is up to 95% ~ 100%. 4. Modifier; emulsifier; buffer; chelating agent; stabilizer. Mainly for canned ham tenderization; canned broad beans in the Yuba softening. Can also be used as soft water, pH regulator and |
