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. The fibers are 6-9 um in diameter and are
considered non-respirable. Upon drying, Type RS-SI Moldable becomes a
rigid structure with useful properties to temperatures of 1100°C
(2012°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. Drying results in a strong, rigid, low density
shape that can be re-wet to restore the original moldability. Baking
irreversibly removes the moldability, leaving Refractory Sheet Type RS-SI
Moldable unaffected by moisture.
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 . RS-SI Moldable is 100% organic free and contains no
refractory ceramic fiber. It is readily machined to precision
tolerances with conventional tooling. |
