摘要： PURPOSE:To provide excellent strength, lightweight properties and safety by a method wherein a plurality of thin inorg. fiber layer mats undulated in the direction right-angled to the longitudinal direction thereof are mutually laminated so that the fibers are mutually entangled in the respective layers and between them to be oriented three-dimensionally at random. CONSTITUTION:Respective layers L1-L10 of inorg. fiber sheets are pressed and contracted so as to have a shape having many corrugated undulations. Since compression force is applied to the layers L1-L10 in the thickness direction thereof at the time of pressing and contraction, the thin inorg. fiber layers f1-f10 of the respective layers L1-L10 are directed in a three-dimensionally random direction and fibers become a mutually entangled state in the respective layers L1-L10 and between them. Since the thin inorg. fiber layers f1-f10 are fixed in this state by a binder, the thin inorg. fiber layers f1-f10 are directed in three- dimensionally various directions such as a horizontal direction, a vertical direction or an oblique direction in the obtained fiber aggregate. Therefore, sufficient yield strength is obtained to the force applied in the thickness direction and compression strength is enhanced.

摘要： PURPOSE:To enhance the mechanical strength of each inorganic fiber board by alternately disposing a plurality of inorganic fiber boards of different density in such a manner as placing boards of high density on both sides of each base board, and sticking their junction faces to one another using a urethane adhesive. CONSTITUTION:Base boards 1 and boards 2 of high density both formed by inorganic fiber boards 2 of rock fiber or glass wool, etc., are alternately disposed while boards 2 of high density are placed on both sides of each base board 1. The junction faces of the boards 1 and 2 are stuck to one another by an urethane adhesive. A surface decorative material 6 such as a hard vinyl chloride sheet or glass clothes, etc., is stuck to the boards. A complex board whose mechanical strength such as refraction resistance, etc., is high is thus obtained.

摘要： PURPOSE:To improve the surface hardenability, surface smoothness, and stiffness by putting in superposed relation the mat base material of an inorganic fiber containing an uncured binder and the high density molded board of inorganic fiber molded higher in density than the mat base material, and then integrating both of them by hot press. CONSTITUTION:During manufacturing of rock fiber, water soluble phenol resin is sprayed and adhered thereto as a binder at the same time of fiber forming, and on a belt conveyer, a raw fiber mat 4 in which rock fibers are gathered into a mat shape is manufactured. In the next place, on the lower mold 2 of a hot press unit 1, a serrated mold 3 is mounted, and then the raw fiber mat 4 is set thereon by leaving the state of fiber arrangement as it is, and further the mat is subjected to hot press molding, thereby obtaining a high density molded board 7 with serration in its one surface. Next, on the same hot press unit 1, another cutout raw fiber mat 4 is set as a mat base material, and a preliminarily high density molded board is put thereon downwardly in the form of allowing the molded surface with serration to be in contact with the mat raw material, and then they are hot press molded to be a predetermined thickness as a synthetic molded board. In this manner, an inorganic fibrous molded board 6 formed by integrating both of them can hold a significant adhesive strength.

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 improve heat resistance and refractoriness by using an aq. soln. of the complex compd. of acidic phosphate and aliphat. amines as a binder to bond inorg. fibers to each other. CONSTITUTION:The complex compd. obtd. by complexing the acidic phosphate with the aliphat. amines is used as the binder. The heat insulating material made of the inorg. fibers greatly improved in the heat resistance and refractoriness without impairing flexibility and handling characteristic is obtd. in this way. The acidic phosphate to be used is exemplified by, for example, Al phosphate, Mg phosphate, etc. While various kinds of the aliphat. amines are exemplified, the aliphat. amines having an amino group and hydroxyl group in the molecule, for example, mono- or diethanol amine, etc., are more preferable in terms of the complexing ability and the exhibition of excellent interfiber bonding strength at a high temp. An aq. soln. of the complex compd. is simultaneously sprayed and is stuck to the surface of the inorg. fibers at the time of forming the inorg. fibers and thereafter, the fibers are continuously passed in a hot wind curing furnace, by which the molding is obtd. with good productivity.
