Properties
White powder; Soluble in water but insoluble in ethanol; Relative density 2.45g/cm3 and melting point 890℃; Deliquescent in the open air. Its aqueous solution shows weak alkalinity and is stable at 70 ℃ but will be hydrolyzed into di-sodium phosphate when boiled.
Application
Sodium pyrophosphate not only has the function of softening water, but also can dissolve insoluble salts of calcium and magnesium. For example, the dirt formed by insoluble calcium soap or other metal soap is mixed in the clothing fiber. It can make it dissolve again and improve the decontamination ability. In addition, sodium pyrophosphate has the function of anti flocculation, which makes the oil emulsify. This is called the gelling property. It can also make the surfactant solution further reduce the surface tension and interfacial tension, and play the role of washing aid. In the food industry as a quality improver, emulsifier, buffer, chelating agent.
Packaging
Plastic knit bag or kraft bag, net weight 25kg.
Besides, we can pack the goods according to the requirement of the client.
