Byname: Pent-sodium Phosphate
Molecular formula: Na
5P
3O
10
Molecular Weight: 367.86
Properties:
White powder; Melting point 622
;
Easily soluble in water; It has got salient chelating capacity
to ions of Ca and Mg etc. and can soften hard water to make
suspension solution become into clear solution; It has got
weak alkalinity but no corrosiveness. 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/cm
3,
medium density 0.51-0.65g/cm
3 and high density
0.66-0.9g/cm
3. This product 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
thermostability, hygroscopicity, solubility and hydration
heat when dissolving .
Uses:
Used as one of the main auxiliaries for synthetic
detergent, synergist for soap; water softener, tanning agent
for leather making, auxiliary for dyeing; 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.
In foodstuff industry it is used as quality improver in the
process of canned food, fruit juice drinks, foodstuffs from
milk or soybeans. It may tender the meat in canned ham and
soften the skin of horse bean in canned horse bean. It may
also serves as a softener or densifier in foodstuff industry.
Packing and storage:
In 25Kg or 50 Kg or 1000 Kg net WPP/PE bags. It must
be prevented from Dampness and water. Don't store it in the
open air.
