ZIRCAR ALUMINA-SILICA
PAPER
GENERAL
INFORMATION
| 소재의 개요ZIRCAR Refractory
Composites, Inc. offers a wide range of insulating refractory
papers. These non woven, non-asbestos, fiber-based products are
engineered as thermal barrier materials for use in high temperature
applications up to 1450°C (2642°F). |
 |
|
Commonly used in the molten metal casting and
heat treating industries, ZRCI materials are also used as specialty
gasketing in the fuel cell, nuclear, glass and electronic
industries, as well as many other applications which require high
temperature stability and low thermal conductivity. They also offer
excellent corrosion resistance and unique handling strength for easy
die-cutting, wrapping and forming.
ZRCI's line of refractory paper include a
binderless product for applications where outgassing cannot be
tolerated, non-respirable grades where fiber content is of concern,
and high purity compositions where the reducing of silica cannot be
permitted.
An additional type of refractory papers
consists of soluble, Non RCF fibers formed into highly insulating
sheets. The fibers are soluble in body fluids and offer an
alternative to refractory ceramic fiber blankets. These grades of
materials meet European regulatory requirements, (Directive
97/69/EC). Please refer to Refractory Sheet Type

Alumina-Silica Fiber
Paper
ZIRCAR Alumina-Silica Fiber Paper
Type ASPA-1 and ASPA-2 are premium grade, lightweight refractory
material made from high purity alumina-silica fibers formed into a highly
flexible sheets. These alumina-silica fiber papers exhibit very low
thermal conductivity and are designed for use in applications where
purity, cracking resistance, high strength and resistance to heat are
paramount. Due to their exceptional resistance to heat flow for their
thickness, they provide maximum thermal resistance where space is at a
premium. These materials are virtually shot free and are the cleanest
refractory papers available. They are ideal for applications up to 1260°C
(2300°F).
Type ASPA-1 contains an organic binder to provide
increased handling strength at room temperature. It possesses excellent
chemical stability and resists attack from most corrosive agents. Because
of its high purity chemistry, it resists oxidation and reduction. If it
becomes wet due to water, steam or oil, its physical and thermal
properties will return upon drying. Type ASPA-2 is produced with no
organic volatiles and will not produce smoke or odor when
heated.
ZIRCAR Alumina-Silica Fiber Paper
Type ASPA-970 is an industrial grade, lightweight refractory material
made from alumina-silica fibers formed into highly flexible sheets. This
alumina-silica fiber paper exhibits very low thermal conductivity and is
designed for use in applications where flexibility, high strength and
resistance to heat are of paramount. Type ASPA-970 is ideal for
applications up to 1260°C (2300°F).
Type ASPA-970 is available in a variety of
thickness.
ZIRCAR Alumina-Silica Fiber Paper Type ASPA-880
is a high temperature, lightweight refractory material made from
alumina-silica fibers formed into highly flexible sheets. It is made from
shorter and smaller diameter fibers with a higher alumina content and are
laid up at significantly higher density. These factors lead to high
temperature, slow shrinkage, higher strength, and better chemical
resistivity. This alumina-silica fiber paper exhibit very low thermal
conductivity and is designed for use in applications where flexibility,
high strength and resistance to heat are paramount. Type ASPA-880 exhibits
low thermal conductivity and is ideal for applications up to 1450°C
(2642°F). It is used in environments where standard ceramic fiber papers
will not survive.
