Sodium Tripoly Phosphate
Applications
Used as one of the main auxiliaries for synthetic detergent, synergist for soap, water softener, tanning agent for leather making, auxiliary for dyeing etc. 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.
Properties
White powder; Melting point 622°C; Easily soluble in water, exceptional chelating capacity to ions of Ca and Mg etc. It can soften hard water and help in settling suspended particles to make the solution clear. It has got weak alkalinity but is not corrosive. It is a surfactant, and has got outstanding emulsification to lubricants and fat. It has different bulk density, i.e. low density 0.35-0.5g/cm3, medium density 0.51-0.65g/cm3 and high density 0.66-0.9g/cm3. It has two crystalline forms, namely Type I (high temperature type) and Type II (low temperature type). The chemical properties of the two types are the same, and the difference between them lies in the thermo stability, hygroscopicity, solubility and hydration heat when dissolved.
