Product Introduction
Detergent grade 94% STPP sodium tripolyphosphate supplier
Product Description:
Properties: White powder or particles, apparent density 0.35 ≤ 0.90 g / cm ~ 3, melting point 622 degrees Celsius. Soluble in water. The
aqueous solution is alkaline and the PH of 1% aqueous solution is 9.7. It is hydrolyzed to phosphite gradually in water, which has good ability of complexing metal ions. It can complex
with calcium, magnesium, iron and other metal ions to form soluble complexes. It softens hard water. As an inorganic surfactants, it has the properties of organic
surfactants.
Applications:
It is mainly used as additive, soap enhancer and prevent oil precipitation and frosting of strip soap. It has strong emulsification effect
on lubricating oil and fat, and can be used to adjust the PH value of buffer soap, softener of industrial water, leather pretanning agent, dyeing auxiliaries, paint, kaolin, magnesium
oxide, calcium carbonate and other industrial suspensions as dispersing agent, drilling mud dispersing agent and papermaking industry as oil repellent.
