Product Description

Product Description

Sodium tripolyphosphate
Molecular formula: Na5P3O10
Molecular Weight: 367.86
CAS Number: 7758-29-4
Other Name: STPP
National Standard:GB 1886.335-2021
INS.: E451(I)

White powder; Melting point 622°C; Easily soluble in water; It has got salient chelating capacity to ions of Ca and Mg etc. and can soften hard water to make suspension solution become into clear solution; It has got weak alkalinity but no corrosiveness. It is a surfactant, and has got outstanding emulsification to 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 crystalline forms, namely Type I (high temperature type) and Type II (low temperature type). The chemical properties of the two types are the same, and the difference between them lies in the thermostability, hygroscopicity, solubility and hydration heat when dissolving .

Production Usage

1. Sodium tripolyphosphate is used as soft water, also used in confectionery industry;

2. 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%;

3. It is used for synergist for soap and preventing bar soap grease precipitation and bloom. It has strong emulsification of lubricating oil and fat. It can be used for adjusting the value of pH of buffer liquid soap. Industrial water softener. Pre tanning agent. Dyeing auxiliaries. Paint, kaolin, magnesium oxide, calcium carbonate, such as industrial in the preparation of suspensions of dispersant. Drilling mud dispersant. In paper industry used as anti oil agents.

4. Sodium tripolyphosphate is used for detergents. As additives, synergist for soap and preventing bar soap crystallization and bloom, industrial water soft water, pre tanning agent, dyeing auxiliaries, well digging mud control agent, paper with oil on preventing agent, paint, kaolin, magnesium oxide, calcium carbonate, such as hanging floating fluid treatment effective dispersant. Food grade sodium tripolyphosphate as a variety of meat products, food improver, the clarification of the beverage additives.
