¡¡¡¡Foam
glass is a new kind of inorganic heat insulating material with
a structure of equally closed cells. It is mainly made of glass added with adequate
foaming agents after heating and baking in high-temperature
tunnel furnace, then annealing and cooling. Because it well
reserves the chemical stability of inorganic glass, it has the
following features: low density, low thermal conductivity, vapor
impermeability, no water absorption, incombustibility, protection
from mould and rat eating, high mechanical strength but easy
to cut and able to bear all kinds of chemical erosions except
the hydrofluoric acid. ¡¡¡¡Foam
glass, nontoxic in itself, has stable chemical properties
and good heat insulating performance protecting from deteriorating
at a wide temperature range from ultra-low temperature to
high temperature. At the same time, it can protect from humidity,
fire and erosion. It is praised as ¡°permanent heat insulating
material with no need of renewal¡± because it is not only safe
but also durable in rigor condition of low and cryogenic temperature,
underground, open air, flammability, moisture sensitivity
and even chemical erosion. Consequently, it is applied widely
as follows:
1.Chemical
Industry£º Reaction equipment, chemical pipes, oil pipes, LNG
pipes, LPG pipes, tank bottoms and insulation projects, etc.
2.Architecture: refrigeratory, ship-building
industry, roof heat-preservation, inside and outside wall
heat-preservation, parking lot and insulation of inner layer
of chimney, etc.
3.Underground Projects: subways, underground
storerooms and tunnels, etc.
4.Others: Military industries, pumice, air-separator
pipes, cold liquid tank bottom insulation, etc.
