|
|
Quality standard：GB9983-88
Molecular formula：Na5P3O10
Molecular weight：367.86
Appearance：White powder
Alias：Sodium Tripolyphosphate
Property：The melting point is 622¡æ, easy to dissolve in the water, remarkable chelating capability to calcium magnesium metallic ions and softens hard water, making suspending liquid turn to solution, weak basicity, non-corrosiveness, surface active agent of inorganic substance with intense emulsification to lubricating oil and fat, the bulk density divides into low density 0.35-0.5g/cm3, medium density 0.51-0.65g/cm3, high density 0.66-0.9g/cm3. Five sodium:I (high temperature) and II (low temperature) two kind of crystal shapes of same chemical property, the difference between it is thermostability and water absorbability I is higher than II solubility, quantity of heat is different.
