High Quality Light Weight Insulating Refractory Castables Good
Insulating Property Grey Insulating Castable
Light Weight Clay insulation castable is characterized by light weight, high
compressive strength, acid and acidproof gas corrosion, thermal
insulation, thermal insulation and low fineness rate. As
lightweight thermal insulation castable is made of certain
refractory materials, such as alumina, firelcay insulation castable
is made of powder and granular refractory with some binder, and has
high fluidity, refractory clay insulation castable is mainly formed
by pouring in construction.
Light Weigh Insulation Castable Description
Firelcay insulation castable is an unshaped material delivered in
the state of dry powder, and mixed before use, can harden at the
ambient temperature to achieve adobe strength after construction
without heating. Refractory clay insulation castable composed of
refractory lightweight aggregate, powder, binder and admixture and
other components. Clay insulation castablehas characteristics of
small volume, high compressive strength, good acid and acid gas
corrosion resistance, good insulation performance, low water
absorption.
Properties of Light Weigh Insulation Castable
.High compactness, high abrasive resistance,
.Excellent thermal shock stability,
.Excellent anti strip performance,
.Excellent fouling resistance,
.Excellent mobility and suitable construction time.
Manufacturing Process of Light Weigh Insulation Castable
Fire clay insulation castable is made from different types of
lightweight aggregates, powders, binders, clay and swelling agents.
Clay insulation castableis a very good new thermal insulation and
energy-saving material. Fireclay insulation castable has high
strength, small bulk density, low thermal conductivity, good heat
insulation performance and convenient construction, and is applied
to various heat insulation parts of kiln.
Advantages of Light Weigh Insulation Castable
Clay insulation castable has good heat preservation performance and
strong integrity, so it saves energy, over 20%, than ordinary
refractories. With high refractoriness and spalling resistance
performance, it has long service life. Fireclay insulation castable
can be used to repair the kiln or furnace, thus improve the service
life of such thermal equipment as well, thus saves money.
