WHAT IS CLASSIFIED PERLITE?
CLASSIFIED PERLITE is to be sized by passing through
different spaced fine sieves after raw perlite is broken
in gaps, which are 0,0 - 0,25mm. Production can
be done in dimensions below and besides in wanted grain
dimensions.
Production can be done in 0 -0.6 mm. , 0.6-1.2 mm. ,
0.6-2.5 mm. , 1.2-2.5 mm. grain dimensions.
USING PLACES OF CLASSIFIED PERLITE
At
melted of mines time, it is used to provide coming
into being dross by being thrown inside furnace and to
be constituted dross under control.
It is put to sole of crucible before being taken
to crucible from furnace of metal in casting industry.
If when perlite get in touch with hot metal, it does a
sort boiling and provides to be taken more clean
casting by carrying to crucible surface of emprutels
which can be found in metal.
At carried of metal into crucible that, it is used
to hindering to surface cooling in casting industry
again.
At casting that being put a quantity to sole of
crucible, is used to prevent cooling from crucible
surface before casting to moulds with better cleaning
of metal. With these intentions, Classified Perlite
has been using in 1180-1300 kg/m3 density and in
0.6-1, 1 -2 mm. grain dimensions.
It is used in
production of expanded perlite.

a) In HEAT INSULATION of Criogenic Tanks
Protection on liquefying heat in pair side
tanks of all gases, which had been liquefied in low
heats (up to -270 °C}, has been being possible with
Etiper "Super fine" which heat conductivity value is
very low. It isn't humudity, doesn't spoil, doesn't burn
and this material, which is cheap, is freely filled
between pair side of tank in atmosphere pressure or
under vacuum. |
 |
| |
|
b) In HEAT INSULATION of different furnaces and of
systems
Etiper "Super fine" has been using to
prevent heat shopping (heat lost) with outside
environment in furnaces which is working environment
up to maximum + 1050 °C. Free filling is done to outside
surface of furnace (between pair side).

c) In Production Of Refrakter Brick
Etiper "Normal" is used as
contribution substance in production of used bricks in
Cauldron, furnace, dampening-beating, thermal operation
and melting stoves which are its working environment up
to maximum + 1050 °C.
Produced refrakter blocks and bricks result of being
tied with clay or calcium silicate cement of Etiper
"Normal" provide high propotion insulation besides being
light. Consequently they do fuel saving.
d) In casting industry
Etiper "Normal" is used as
contribution substance to casting sand. It is added
volumely %8-12 proportion to casting sand in casting of
iron-steel, % 20-30 proportion as for in casting of
other materials.
ADVANTAGES, WHICH WILL PROVIDE, OF ETIPER "NORMAL"
IN FOUNDRY
- It prevents abnormal surface tensions because of
providing slowly and balanced cooling of metal.
- At casting time, it doesn't Burn, doesn't take off
Gas and doesn't enter to Reaction with Metal.
- It gives permission to exit by means of
emptinesses and canals which are in Building of gases,
which is constituted at casting time.
- Clean, strong, high in quality and productive
casting are got.
- It lessens workmanship and cleaned time of
production becausae of taking down casting errors to
minimum.
