摘要:
Non-woven mat including basalt and amorphous refractory ceramic fibers, bio-soluble ceramic fibers, and/or heat-treated silica fibers. Embodiments of the non-woven mat surprisingly have a Resiliency Value after three thermal cycles from 25° C. to 700° C./400° C. of the Real Condition Fixture Test at least 1.1 times greater than the Resiliency Value of a comparable non-woven mat consisting of any individual type of fibers of the non-woven mat. The non-woven mats are useful, for example, in pollution control devices and other thermal insulation applications.
摘要:
The invention relates to a method for manufacturing an insulating composite containing mineral fibers, aerogel and binder. This method implies the step of suspending the fiber webs and aerosol in an air flow thereby disentangling the fiber webs and mixing fibers, aerosol and eventually binder homogeneously. The apparatus described combines spinning of the fibers, collecting them as webs, disentangling the fiber webs in suspended air, mixing the fibers with aerogel and cement as well as pressing and curing the mixture to a consolidated product of density 150 to 800 kg/m3.

摘要:
The present invention aims at providing an inorganic fiber molded body that is excellent in scale resistance, thermal shock resistance and mechanical shock resistance, and prevented from suffering from shrinkage when used under high-temperature heating conditions. The inorganic fiber molded body of the present invention is produced by impregnating a needle blanket of inorganic fibers with a liquid material of a precursor of a spinel-based compound represented by the general formula: MgxAlyO4 wherein an atomic ratio (y/x) is not less than 2 (y/x 2); drying the thus impregnated needle blanket; and firing the dried needle blanket to convert the precursor into an oxide thereof.
