    摘要: A fireproof, compressible, intumescent, elastomeric material useful to seal expansion joints, curtain wall gaps and penetrations in floors and walls in order to prevent the passage of flame and smoke. A seal of the material retains strength before and after exposure to fire and provides superior resistance to the impact, erosion, and cooling effects of a hose stream used to combat a fire. The composition of this compressible, fireproof material consists of elastomers, vulcanizing agents, fillers, softening agents, and an intumescent. This fireproof material may be in cellular or noncellular form with various degrees of compressibility and softness. It can be produced in sheets, molded parts, and continuous length strips. It may be vulcanized or nonvulcanized.

    摘要: A sealing member for use in a gas preheater is adapted to seal a gap between an outer peripheral portion of a rotor and a housing in the gas preheater or a gap between a side face of the rotor and a radial sealing member. At least a part of said sealing member is made of an inorganic glass and/or a wear resistive ceramic having a coefficient of thermal expansion of not more than 70.times.10.sup.-7 /.degree. C. A sealing member for use in a gas preheater may comprise a heat resistive ceramic, and a corrosion resistive steel, wherein the ceramic is substantially surrounded with the corrosion resistive steel, excluding a sliding surface of the ceramic.
