Product Description

Product Description

Sodium tripolyphosphate stpp

STPP or sodium triphosphate is an inorganic compound with formula Na5P3O10. STPP,Sodium Tripolyphosphate is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. Sodium tripolyphosphate is produced by heating a stoichiometric mixture of disodium phosphate, Na2HPO4, and monosodium phosphate, NaH2PO4, under carefully controlled conditions. Sodium tripolyphosphate sTPP.

Application

STPP tech grade is used as additive in detergent synthesis, ceramics production, soap synergist. Has strong emulsifying property to lubricant and fat, to adjust the PH value of buffer liquid soap, water softener for industrial water, pretanning agent for leather production, in dyeing additive, paint, kaolin, magnesium oxide, calcium carbonate and other industries as dispersant for the preparation of suspension, as dispersant in drilling fluid, as anti-oil agent in paper-making industry.1. Water softener and buffering agent in detergent industry
2. Quality modifier, pH adjustment, water reserving agent and other functions in food industry
3. Paper making
4. Dispersing agent in oil drilling mud
5. Ceramic, mining, water treatment industry and etc.
Function in detergent industry:
STPP is a good auxiliary in detergent industry, the usual dosage is about 10~35%, the function of STPP in detergent system are:
1. Soften the hard water by reacting with metal ions of Ca2+, Mg2+, Fe3+ and others to make them from insoluble to soluble Na5P3O10+Ca2+ ---> Na3(CaP3O10)+2Na+
2. Enhancing the emulsifying and dispersing power, to increase the solubility of protein and dust which normally existing in
thefabrics from daily life
3. Buffering agent, to make the pH value of detergent solution on the level of 9~9.5, so that those acid dirt can be easily
removed from fabrics
4. Anti-caking agent for detergent powder. Since detergent powder is easily caking in exposed air, STPP can absorb the moistureand become Hexahydrate, which is dry and free flowing.
