| Scientific name: |
Calcium Hydroxide Phosphate |
| Molecular
formula: |
Ca5(PO4)3OH |
| Abbreviation: |
TCP |
| Molecular weight: |
502 |
| Property:
|
An amorphous white powder with relative density
at 3.18 and melting point at 1670°C,easily soluble
in weak hydrochloric acid and nitric acid,slightly
soluble in cold water and ethanol.
|
| Standard: |
HG/T3583-1999 |
| Application: |
An excellent inorganic disperser.As it is able
to polymerize resin even particle size,and is easy
of controlling viscidity,hard of sticking on wall
and stirrer of tank,decrease the time of clearing
and subsequently improve productivity dramatically
than organic dispersers,it takes a lion share in
the disperser market for suspension polymerizing.It
is not only extensively applied in polymerizing
PS,EPS,PVC,ABS,PMMA and SAN but also in isolating
agent for anti-sticking resin,biomaterial,food,dying
pigment,water treatment agent,rubber,pharmacy,metal
pulverizing,ceramic and fluorescent material. |
| Package: |
Net weight 10 kg sack or 20kg sack,with inner
polyethylene bag and outer woven sack.Keep away
from solarization,rain and damage to package during
transportation;store in a shaded,ventilated,and
dry warehouse to prevent from sunshine and dampness. |
