摘要： PURPOSE:To improve fire resistance by preventing a wooden layer incorporated into an non-combustible mat floor from taking fire. CONSTITUTION:An wooden layer 3 for giving hygroscopicity is laminated on a fiber layer 2 to which inorganic fiber bonded with binding agent is bonded, and a tatami mat face 4 is stacked on it through a non-combustible felt 6. The wooden layer 3 is prevented from burning by the non-combustible felt 6. As required, the fiber layer 2 is lined with a synthetic resin foam body 1 or insulation board. Accordingly, the wooden layer 3 is prevented from taking fire by the non-combustible felt 6. The fire resistance of the tatami mat floor is, therefore, increased to prevent the wooden layer 3 from burning even if the tatami mat face 4 is burnt when fire, etc., is produced for increased safety.

摘要： PROBLEM TO BE SOLVED: To allow repeated use and to facilitate installation and removal by forming a heat insulating cover into a two-piece shape and integrating the two-piece heat insulating cover by means of a stopper. SOLUTION: A heat insulating cover is produced by vacuum suction of slurry, which is prepared by mixing ceramic fiber, cement, and water together, into a predetermined shape metal die. In this process, the heat insulating cover is formed into a two-piece type shape in compliance with the shape of a valve or a flange to be thermally insulated, and the two pieces are integrated together by means of a stopper. Therefore, installation of the heat insulating cover to a valve part in a pipe is accomplished when a heat insulating cover 1 and a heat insulating cover 2 are arranged so as to put the valve and the pipe between them and stoppers 5, 5', 6, 6' are fastened.

摘要： PURPOSE:To form a heat-insulation material without causing deflections or chipped corners, by providing a plurality of grooves in a heat-insulating plate made of inorganic fibers and in one surface of foamed resin and fitting the grooved faces or bonding the surface and sideface of the heat-insulating plate by use of foamable resin. CONSTITUTION:Fibrous inorganic fibers like rockwool of the like are binded by a binder made of a thermosetting resin to make a heat-insulating plate 1 having numerous pores. And a grooving work is applied on the rockwool heat-insulating plate 1 and a foamed phenol resin 2 is fitted thereon. Or the one face and the both end faces are coated with a foamed phenol resin 4 without applying any works on the rockwool heat-insulating plate 1. In this way, a heat-insulating plate having fixed shape with no bend nor chipped corner can be obtained.

摘要： PURPOSE:To secure lightweight, good handling and good execution of the above member, to enhance bending resistance thereof and to enable the manufacture even it is a large-sized member by adding a mixture of shortly cut staple fibers and a thermosetting resin to the surface of an uncured base material fiber layer to which a thermosetting resin binder is sprayed and bonded to form a high density fiber layer thereto before integrating both layers. CONSTITUTION:A water-soluble phenol resin is sprayed to rock wool as a binder at the time of the carding of rock wool using a cotton-carding machine 1 and inorg. fibers are mutually bonded to form a base material fiber layer 3 on a mesh conveyor 2. Next, rock wool fibers mixed with the phenol resin are obtained in the same way and cut into staple fibers by feather mill 4 being a cutter and the staple fibers are arranged and added to the surface of the base material fiber layer 3 on the mesh conveyor 2 so that the whole becomes uniform to form a high density fiber layer 5. Thereafter, both layers are cured under heating while compressed between lower and upper conveyors 7, 8 within a heating oven 6 to form a molded member 9 having a two-structure consisting of the high density fiber layer 5 and the base material fiber layer 3.

摘要： PURPOSE:To improve the homogeneity by reducing the maldistribution of fibers in a product and consequently obtain a high strength and low absorption product by a method wherein the fibers, to which specified surface treatment is applied, are dispersed in water and hydroextracted in a paper making process by adding various paper-making aids in combination. CONSTITUTION:Inorganic fiber aggregate may well be dispersed in water after being adhered by surface active agent or both the aggregate and the agent may well be simultaneously dispersed in water. The resultant inorganic fibers are agitated with water and, after that, cements and aggregate and the like, when necessary are added to said fibers. Further, pulp, clays and polymeric flocculant in combination are added to the resultant fibers so as to form fiber-containing cement slurry. The slurry is hydroextracted in paper making process with a cylinder mold, wound up and piled up so as to be turned into a product through press-molding process. Since slurry, in which fibers are uniformly dispersed in water, can be formed, the maldistribution of the fibers in the product is reduced and consequently the lowering of homogeneity, strength and the like can be reduced. Furthermore, the water filtering time can be controlled and the trapping property of cement particle can be improved.
