Abstract: PROBLEM TO BE SOLVED: To provide the moisture regulating material useful as the repeatedly usable moisture regulating material for dew condensation regulation and to provide its production method. SOLUTION: The composite of a porous metal hydroxide and a by-product having hydroscopicity is produced, by precipitating a metal hydroxide by adjusting the hydrogen ion concn. of a metal chloride aq. soln. with ammonia water, etc., and subjecting the hydroxide gel obtained by agitating the hydroxide in a hot water bath to heat treatment at the temp. at which a hygroscopic by-product is not thermally decomposed. In this way, the moisture regulating material for dew condensation usable repeatedly by absorbing the water vapor more than 60% of one's weight under the high humidity condition of >=80% relative humidity and easily releasing the water vapor under the usual humidity condition of

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a porous wall material, in which molding and solidifying are conducted without reducing the steam absorption of porous powder having no moldability and which displays an autonomous humidity-conditioning function. SOLUTION: A porous wall material combining hygroscopicity and moisture absorption characteristics without damaging porosity and having pores in nanometer order is manufactured by preparing and drying molded and solidified forms by utilizing the viscosity of a silica sol. Accordingly, a functional material autonomically having a humidity-conditioning function can be supplied without imparting energy from the outside by a capillary condensation phenomenon generated in pores in nanometer order by providing an energy-conservative porous solidified-form manufacture as a molding method making the strength of porous powder having no moldability and steam absorption coexist.

Abstract: PURPOSE: To make a laminar inorganic compound having a complicated structure and composition into a film, arrange the thin laminar particles correctly and manufacture a laminar particle film by turning the surfaces of the laminar particles hydrophobic, dispersing the particles on a water surface and making the particles adhere to a substrate. CONSTITUTION: The surfaces of laminar particles are turned into hydrophobic and dispersed on a water surface, and then made to adhere to a substrate to manufacture a laminar particles film. On the other hand, the manufacturing processes are repeated to control the thickness of laminar particle film. In the manufacture, for example, a film manufacturing device composed of a trough 1, a movable barrier 2, a vertical immersion plate 3 and a surface pressure sensor 4 is used. At that time, the formation status and reproducibility of the film are presumed based on the measurement (π-A curve) of surface pressure (π) and development area (A). As a result, when the ratio between the dispersed liquid volume and the maximum development area is too large, the particles on a development surface are brought into contact with one another to form weakly composite particles, which is not preferable as it takes a long time to form desired monolayer particles.

Abstract: PURPOSE:To efficiently separate and recover CO2, discharged by burning petroleum, coal, a gas, etc., in a state of a high concentration and a high temperature before discharging into the air. CONSTITUTION:The method for recovering high-temperature carbon dioxide in a waste gas is to feed a prescribed amount of the waste gas still kept at a high temperature due to combustion into a separating cylinder 3 to which a carrier gas is fed at a constant flow rate at a prescribed time interval, bring the waste gas into contact with a ceramic separating agent, filled in the separating cylinder 3 and having a larger retention time from adsorption of CO2 thereon to the desorption thereof than that of other gases, discharge the gases other than the CO2 by the carrying away with the carrier gas in a housing chamber 6 for the separating agent, then change over a discharge port from the separating cylinder 3 to the side of a bypass flow passage 9 with a changeover valve 7, separate and recover the CO2 in the bypass flow passage 9.

Abstract: PURPOSE:To produce the subject mineral moldable without requiring addition of an organic additive by applying a hydrothermal treatment to a powdery two-component system mineral of silica-alumina in an acidic or neutral solution and forming a thin kaolinite film. CONSTITUTION:A powdery two-component system mineral of silica-alumina such as mullite and an acidic or neutral solution is tightly sealed in a pressure tank such as an autoclave. A hydrothermal reaction is carried out by heating to convert the surface of the powdery mineral into a clay-like material exhibiting plasticity. The particle size of the powdery mineral is not especially restricted and about 3 to 10mum is preferable. As the condition of the hydrothermal reaction, the reaction temperature is preferably 200 to 250 deg.C in the case of 7 day reaction period and the most favorable result can be obtained especially at about 230 deg.C. Further, an acidic solution is preferably used as the solution and a 0.1 N to 0.01 N hydrochloric acid solution is especially preferable. As the result of this hydrothermal treatment, a thin kaolinite film can be formed on the surface of a mineral such as mullite.
