Product Description
Sodium tripolyphosphate STPP is used in laundry detergent as a detergent "builder". The paper presents the chemical method of obtaining "heavy", i.e. with higher bulk density granulated sodium tripolyphosphate. The bulk density of sodium tripolyphosphate was increased by preparing a mixture of the dried sodium phosphates, the recycled subgrain of STPP and water in specific proportions and calcining this mixture for 1 hour at 400 degrees C and 550 degrees C (to obtain a proper STPP form) in the chamber kiln. This method allows producing the granular sodium tripolyphosphate with high bulk density (1.04 - 1.07 kg/dm(3)) and a high content of Form I or Form II, respectively.
1. Product Description
Appearance : white granular or powder
Sodium tripolyphosphate is an inorganic compound with formula Na5P3O10. Sodium triphosphate is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid.Sodium tripolyphosphate is produced by heating stoichiometric mixture of disodium phosphate, Na2HPO4, and monosodium phosphate, NaH2PO4, under carefully controlled conditions.

3. Usage
Used in detergent, synergist for soap; water softener; tanning agent for leather making,
auxiliary for dyeing; As an effective dispersion agent for suspension solutions of coatings,kaolin, magnesium oxide, calcium carbonate and drilling mud etc.; As an oil contamination resistance agent in paper production. In foodstuff industry it is used as quality improver in the process of canned food, fruit juice drinks, foodstuffs from milk or soybeans. It may tender the meat in canned ham and soften the skin of horse bean in canned horse bean. It may also serves as a softener or densifier in foodstuff industry.
