REFRACTORY SHEET TYPE RS-SI SILICA
MOLDABLE
GENERAL INFORMATION
|
ZIRCAR Silica Moldable Type RS-SI
Moldable is a wet blanket that is a combination of high purity
amorphous silica fibers and inorganic silica binder. Upon drying
Type RS-SI Moldable becomes a rigid structure with useful properties
to temperatures of 1200°C(2192°F).
Type RS-SI Moldable exhibits good wet
handleability. It is easily cut with scissors or a knife and can be
applied directly to equipment with complex contours. It can also be
used to fabricate flat sheets or boards. Drying can be accomplished
in an oven , with a hot air gun or torch, or by exposure to heat in
the application. Removal of water renders Type RS-SI Moldable
permanently rigid.
Type RS-SI Moldable exhibits
excellent resistance to attack by most chemicals with the exception
of caustics. It will tolerate all acids except hydrofluoric acid. It
is not wet by molten aluminum and is useful in many applications
where Refractory Ceramic Fiber is not desired. |
