An objective of the present invention is to implement a window structure body whereby a scene viewed from within a room space is ensured by day, and it is possible to prevent peeping from outside the room space either day or night. Provided is a window structure body, which is provided with a translucent planar light emitting body with a half-mirror layer on the inner side, and glass plate bodies on the inner side and the outer side of the planar light emitting body. The planar light emitting body is formed from a translucent resin plate, a light emitting element which is disposed upon the end face of the resin plate, and a light diffusion layer which is disposed upon the surface of the translucent light plate, and light from the light emitting element enters via the end face of the resin plate, is reflected by the half-mirror layer, and is diffused with the light diffusion layer, thereby causing the surface of the planar light emitting body to emit light.

The invention discloses a high-flame-retardance fireproof cable made of inorganic materials. The high-flame-retardance fireproof cable comprises a plurality of wire cables, a fire-resistant layer made of inorganic materials and a flame-retardant jacket. The fire-resistant layer made of the inorganic materials is extruded on the wire cables; the flame-retardant jacket is sleeved on the fire-resistant layer made of the inorganic materials; each wire cable consists of a copper conductor and a vitrified silicon rubber insulating layer extruded on the copper conductor; and a filling layer is filled in the fire-resistant layer made of the inorganic materials. The high-flame-retardance fireproof cable is characterized in that the fire-resistant layer made of the inorganic materials comprises, by weight, 85% of magnesium hydroxide, 6% of serpentine powder, 4% of magnesium calcium carbonate, 3% of sodium silicate and 2% of chlorinated paraffin which are squeezed to form the fire-resistant layer made of the inorganic materials. The insulating layer is made of vitrified silicon rubber, and because the insulating layer has high fire resistance and the vitrified silicon rubber is vitrified at a high temperature, the insulating performance of the cable is guaranteed during spontaneous combustion of the cable and external fire disasters. Besides, as the fire-resistant layer made of the inorganic materials is totally made of the inorganic materials by cold stirring and extruding, the materials cannot be combusted during the fire disasters, and flame-retardant and fireproofing effects can be achieved effectively.

The invention relates to a refractory spray coating material, in particular to an anti-skinning spray coating material for a cement kiln. The anti-skinning spray coating material comprises flint clay, SiC, Guangxi white mud, alpha-Al2O3 micro powder, high-aluminum fine powder, SiC fine powder, pure calcium aluminate cement, spodumene, pyrophyllite and polypropylene fibers. The anti-skinning spray coating material for the cement kiln can play an effectively anti-skinning role at the positions of a feed pipe, a smoke chamber and the like of the cement kiln, is excellent in medium-temperature and high-temperature resistance and outstanding in thermal shock stability performance and can avoid cracking during rapid temperature rise. Besides, the anti-skinning spray coating material for the cement kiln is rapid in construction by the aid of a semi-dry spray coating construction mode, and is low in rebound rate after construction.

Joint attaching a structural element (10) to a composite part (20) comprising a metallic attachment (40), this joint being subjected to a fire source on one of its sides, the fire side, the joint comprising a retaining device (50) locate at the side of the joint opposite to the fire side, the cold side, the retaining device (50) comprising a first surface (51) that is in contact with the metallic attachment (40), and a second surface (52) which is in contact with the composite part (20), the second surface (52) having a bigger area than the area of the first surface (51), the retaining device (50) being made of a material with a high thermal conductivity. The invention also refers to an aircraft comprising such a joint.
