H.S. No.: 2835.3100
Description: white powder;
melting point 622C; 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/cm3, medium
density 0.51-0.65g/cm3 and high
density 0.66-0.9g/cm3. 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, and solubility
and hydration heat when
dissolving.
