    Information details

    三聚磷酸鈉(stpp)


    Product Name: sodium tripolyphosphate

    Alias: pentasodium phosphate

    English Name: sodium tripolyphosphate

    Molecular formula: na5p3o10

    Molecular weight: 367.86 (according to 1985 international atomic weight)

    Performance characteristics: white powder or powder, apparent density 0.35-0.90g/cm3, melting point 622 ℃. Soluble in water. The aqueous solution is alkaline, and the pH of 1% aqueous solution is 9.7. It is gradually hydrolyzed into phosphite in water and has a good ability to complex metal ions. It can complex with calcium, magnesium, iron and other metal ions to form soluble complexes. Can soften hard water. As an inorganic surfactant, it has certain properties of organic surfactant.

    Usage: mainly used in synthetic detergent as additive, soap synergist and preventing soap grease precipitation and frost. It has a strong emulsifying effect on lubricating oil and fat. It can be used to adjust the pH value of buffer soap solution. It can be used as dispersant when preparing suspension in industries such as water softener, tanning pretanning agent, dyeing assistant, paint, kaolin, magnesium oxide and calcium carbonate for industrial water, dispersant for drilling mud, and anti oil stain agent in papermaking industry.
