Abstract: PURPOSE: To obtain the humidity adjusting building material at a low cost by mixing allophane or imogolite and the setting hardening agent, and forming them for setting, or mixing the allophane or imogolite with the ceramics raw material, and burning it so as to form the building material for forming a space. CONSTITUTION: Allophane or imogolite as a main body of the volcanic ash soil is mixed with the setting hardening agent such as mortar, gypsum, slaked lime, dolomite, and water is added thereto for kneading at need, and after forming, it is hardened by steam curing. Or, allophane or imogolite is singly used, or mixed with the ceramics raw material, and formed, burned so as to form the humidity adjusting building material. In this case, the reinforcing material and the pigment can be added at need. This humidity adjusting building material is applied to wall, floor, ceiling, shelf, and door so as to absorb the moisture, and the generation of dew condensation and mold is prevented. The building material having the excellent' moisture absorbing characteristic can be thereby obtained at a low cost.

Abstract: PROBLEM TO BE SOLVED: To synthesize aluminosilicate in a large amt. in a short time while suppressing energy consumption by mixing a silicon compd. soln. of high concn. and an aluminum compd. soln., dropping an alkali soln. into the mixture to neutralize, and separating and collecting a solid content produced at room temp. SOLUTION: A silicon compd. soln. of 10 to 500 mmol, and an aluminum compd. soln. of 10 to 100 mmol are mixed with 0.5 to 2.0 molar ratio of silicon/ aluminum, and then an alkali soln. is dropped into the mixture soln. by 0.5 to 2 mol/min rate to neutralize and to produce a solid content at room temp. The produced solid content is separated by filtering and with a centrifugal separating machine, then cleaned, and dried to obtain spherical aluminosilicate. The obtd. spherical aluminosilicate is a highly functional porous material having 1 to 10 nm particle diameter, >=70 m /g specific surface area by nitrogen adsorption, and 0.5 to 2.0 silicon/aluminum ratio, and can be synthesized in a large amt. at room temp.

Abstract: PURPOSE:To excellently agitate a reactant in the hydrothermal reaction and to increase the reaction rate by hermetically enclosing a small-piece agitating medium in a pressurized reaction vessel, rotating and agitating the vessel. CONSTITUTION:The inner vessel 2 contg. a bottomed inner cylinder 21 charged with distilled water and a reactor is placed in the bottomed outer cylinder 11 of the outer vessel 1. A pressing member 3 is placed on an inner lid 22. The outer lid 12 screwed into a pressing member 4 is screwed into the outer cylinder 11 and bound. The head 42 of the pressing member 4 is rotated clockwise, and its tip 41 is pressed on the pressing member 3. Consequently, the inner lid 22 is pressed vertically on the inner cylinder 21 by the pressing force, the seating face 23 of the inner cylinder 21 is closely attached to the matching face 24 of the inner lid 22, and the inner vessel 2 is liquid-tightly closed. The pressurized reaction vessel 31 thus prepared is horizontally placed on a couple of rotation transmitting rods 10, kept at a constant temp. and rotated. Alumina and quartz are exemplified as the material for the small-piece agitating medium inert to the hydrothermal reaction.

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.
