摘要： A heat-insulating protective member for skid posts contains a needled blanket of inorganic fibers. At least some of the needled blanket has, disposed therein, an impregnation part where an oxide-precursor-containing liquid is adherent in an undried state. The impregnation part has a water content of 50-400 parts by mass per 100 parts by mass of the inorganic fibers of the impregnation part. The water content of the heat-insulating protective member is 50-400 parts by mass per 100 parts by mass of the inorganic fibers of the heat-insulating protective member. The oxide-precursor-containing liquid contains ingredients that, upon burning, yield a composition containing Al2O3 and CaO. The oxide-precursor-containing liquid is adherent in an amount of 2-50 parts by mass in terms of oxide amount per 100 parts by mass of the inorganic fibers of the impregnation part. A molar ratio of Al/Ca, in the whole impregnation part is 10-330.

摘要： The inorganic fiber molded body of the present invention is characterized in that the molded body has an extremely light weight, and is free from problems such as scattering of fibers and particulate matters from a surface thereof and environmental pollution such as generation of harmful gases. In addition, the present invention provides an inorganic fiber molded body that is excellent in not only thermal shock resistance and mechanical shock resistance but also a high-speed wind erosion resistance, well-balanced in properties and can be used in the applications of various heat-insulating materials. The present invention relates to an inorganic fiber molded body comprising inorganic fibers and inorganic binder particles and having at least one set of a high-fiber density region and a low-fiber density region, in which a ratio of a content of the binder particles in the high-fiber density region to a content of the binder particles in the low-fiber density region as measured by a predetermined method is 0.5:1 to 5:1; and a number-average particle diameter and the number of the inorganic binder particles on an outermost surface of the molded body as measured by a predetermined method are 20 to 35 μm and less than 15, respectively.
