Product Description

Product Description

High Quality 94% Sodium Tripolyphosphate (STPP) Used In Detergent Paint Water treatment

Sodium tripolyphosphate is a white powder crystal with good fluidity. The density of type 1 is 2.62g/cm³, and the density of type 2 is 2.57g/cm³. Melting point 622ºC. It is easily soluble in water, and its aqueous solution is alkaline.

Solubility: soluble in water, 20g/100mL (20ºC)

Sodium triphosphate (STPP or sodium tripolyphosphate) is an inorganic compound with formula Na5P3O10. It is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. It is produced on a large scale as a component of many domestic and industrial products, especially
Detergents.
Environmental problems associated with eutrophication are attributed to its widespreaduse.

Application

1.STPP tech grade is used as additive in detergent synthesis, ceramics production, soap synergist.
2.Has strong emulsifying property to lubricant and fat, to adjust the PH value of buffer liquid soap.
3. Water softener and buffering agent in detergent industry
4. Quality modifier, pH adjustment, water reserving agent and other functions in food industry
5. Paper making
6.Dispersing agent in oil drilling mud
7. 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 the fabrics 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 moisture and become Hexahydrate, which is dry and free flowing.
