Expansion perlite (EXPANDED PERLITE)
Expanded perlite is preheated, baked instantaneous expansion by
expaned perlite ore, which is made after an internal honeycomb
structure of the white granular material.
Perlite Principle and the expansion of configuration:
Expanded perlite is crushed by the ore, dealed with the rapid
heating (1000¡æ above). After the moisture vaporization ores and
minerals in the particles soften internal expansion, the
formation of porous structure, expansion to the original 10-30
times. The expanded perlite can be sorted to 3 fonfiguarations
by the technical conditions. They are the open hole (OPEN CELL),
the obturator (CLOSED Cell), the hollow hole (BALLOON).
White Granulated (internal cellular structure) £©
Non-toxic, odorless, corrosion
Neutral PH6.5-7.5, Acid and Basic, Resistance, not burning
Light weight
The expanded perlite main characteristics :
Light porous Unburning insulation
Acoustic waterproof corrosion resistance
The brilliant expansion perlite is a new type material of
thermal insulating and heat-resistantor.Using liquefied
pertrolum gas as fuel and selectivly particle size of high
quality graded perlite as raw material, the product shall be
formed at a sudden and controlled high temperature. Compared to
ordinary expansion perlite, the outstanding characteristics are
is its low bulk density, low heat exchange coefficient as well
as exhibiting symmetrical size. The product is mainly used for
the storage of liqufid industrial gasses in double wall cold or
storage sphere as a good low temperature insulation material¡£
