摘要： PURPOSE:To enhance not only reliability of quality but also productivity and economical efficiency, by forming a synthetic resin foam composed of an impermeable material in a bag body and closely contacting the material with the bag body by the moldability in foam formation. CONSTITUTION:A synthetic resin foamable raw liquid is injected in a bag body 1 composed of an impermeable material molded into a required shape from the opening part provided to a part of said bag body 1, and foamed and cured to mold a synthetic resin foam 3. Next, the opening part is closed by seal processing such as thermal welding processing to obtain a float wherein the bag body 1 and the synthetic resin foam 3 therein are integrated in a closely contacted state without leaving any gap therebetween.

摘要： PURPOSE:To sufficiently ensure fire resisting performance of structural steel edge sections without thickening the fire resisting coating of a structural steel. CONSTITUTION:Edge sections 1a of a structural steel 1 are coated with wet felt material 2 made of inorganic fibers infiltrated with binder in advance. After that, the surface of the structural steel including the edge sections 1a is coated with fire resisting coating materials 3 through spraying execution. Accordingly, the coating at the structural steel edge sections 1a is thicker than that at another section because of the wet felt materials 2, and fire resisting performance of the structural steel can be promoted without thickening the fire resisting coating materials for general sections. The wet felt material is made adhesive through natural drying and have appropriate flexibility, and thereby it is so simple and easy that the wet felt material 2 is applied on the structural steel and integrated.

摘要： PURPOSE:To obtain a fireproof coating material causing expansion at a high rate by uniform foaming at the time of fire and exhibiting superior heat insulating property by incorporating a specified substance as a blowing aid into a fireproof coating material having a prescribed compsn. and giving a coating film convertible into a heat insulating covering layer by foaming at the time of a fire. CONSTITUTION:Thermally expandable microcapsules (e.g. 'Matsumoto Microsphere F30(R)' made by Matsumoto Fats and Oils Pharm. Co. are incorporated as a blowing aid into a fireproof coating material consisting essentially of a thick aq. soln. of alkali silicate (e.g. No.3 sodium silicate) and a heat resistant inorg. filler (e.g. a silica powderwollastonite mixture) and giving a coating film convertible into a heat resistant covering layer by foaming at the time of a fire.

摘要： PURPOSE:To obtain the titled foam having excellent mechanical properties, flame resistance, and heat resistance by compounding a liquid phenolic resin of resol type, an acid curing agent, a foam stabilizer, a foaming agent, and a specified inorganic powder. CONSTITUTION:100pts.wt. gypsum such as calcined alpha-gypsum is mixed with 10- 500pts.wt. inorganic compound containing water of crystallization such as Al (OH)3 to give inorganic powders having a particle size of 325 mesh or smaller. Then an acid curing agent (e.g. an inorganic or organic acid) is added to a premix obtained by mixing 100pts.wt. liquid phenolic resin of resol type which is obtained by the polycondensation of a phenol and an aldehyde in the presence of a basic catalyst and has a viscosity of 500-1,500cP (at 25 deg.C), a foam stabilizer (e.g. a silicone surface active agent), a foaming agent (e.g. a halogenated hydrocarbon), and 10-500pts.wt. inorganic powders aforementioned, and is mixed by stirring to give the titled phenolic resin foam.

摘要： PURPOSE:To reduce manufacturing cost by manufacturing a heat-insulating material for a pipe by continuously shaping a material to a required form by a molding section mounted to an endless travelling belt. CONSTITUTION:An expanding undiluted raw solution 12 in a synthetic resin foam continuously fed to the start end section of a flat section 2 from a discharge nozzle 10 under the state in which an endless travelling belt 1 to which mold release treatment is executed is made to travel is transferred to a molding section 8 while it continues a gas blowing reaction on the flat section 2, and the gas blowing reaction is completed in the molding section 8. The gas blowing reaction is completed, the synthetic resin foam is separated from the molding section 8, and further transferred, and a cutter 9 is operated and the synthetic resin foam is cut when the foam reaches to a predetermined length, thus continuously manufacturing a heat-insulating material for a pipe. The strength and dimensional stability of the heat-insulating material for the pipe to be obtained are improved because the synthetic resin foam is bonded by utilizing self-adhesive properties.
