PROBLEM TO BE SOLVED: To provide a composite material useful in producing a ceramic filter or the like, its production method, and a ceramic porous body obtained by using the composite material.
SOLUTION: A flexible slab foam produced by a normal method is cut into a sheet foam having a specified dimension and subjected to an explosion treatment to remove the cell membranes, and a binder is prepared by compounding an ethylene-vinyl acetate copolymer emulsion with thermally expansible microcapsules. The sheet foam is immersed in the binder at normal temperature for 1 min, taken out, and pressed with a calendar roll to press out a part of the binder. The sheet foam is then dried at 50°C for 5 min to remove a part of water and heated at 140°C, the thermal expansion temperature of the microcapsules, for 1 min to thermally expand the microcapsules to form hollow particles 1. Thus, the hollow particles 1 are bonded to each other and so are part of the hollow particles 1 to the foam backbone, giving the objective composite material.

(57)【要約】 セラミックパッキングエレメント(500)は、間に溝を形成する平行なリブ(504)を有するセラミックプレート(502)のスタックから形成される。 溝は、対向するプレートと接触することによってチャネルに形成される。 リブ(504)は、隣接するプレート上のリブの端面と係合したり、あるいは、対向するプレートのリブ(504)と相互に挟み込んで、小さなチャネルを形成しても良い。 プレート(502)は、未焼結状態におけるプレート(502)のスタックを焼成することにより、あるいは珪酸ナトリウムなどの無機接着剤によって硬化したプレート(502)を接着することにより、互いに接着される。 圧力降下及び破壊は減少するであろうし、質量転移及び熱効率は、チャネルへの入口(542)を拡大することにより、あるいはリブ(504)の間のプレートを貫通する孔を設けることにより、増加する。 エレメントは、カラム内に置かれる前に、エレメントのアセンブリの周りに金属バンドを巻き付けることにより、より大きなユニットにあらかじめ組み立てられても良い。 |

PROBLEM TO BE SOLVED: To provide the porous body which has a high porosity and high mechanical strength and also, the void distribution and porous structure of which can freely be set.
SOLUTION: This porous body has a porous structure in which the contact points of inorganic aggregate granules 1 each having a through-hole(s) within it and/or grooves and projections in its surface, with each other are joined together with an inorganic binder and which contains voids among the aggregate granules 1 and within each of the granules 1. This production comprises: filling a mold 2 with the inorganic aggregate granules 1 each having a through-hole(s) within it and/or grooves and projections in its surface; then, allowing a slurry of the same material as that of the aggregate granules 1 to flow into the mold 2 from its upper side; discharging the slurry from the mold 2 after retaining the slurry in the mold 2 for a specified time to join the contact points of the aggregate granules together to form a body; and then, drying the formed body, withdrawing the body from the mold 2 and sintering the body.

PROBLEM TO BE SOLVED: To enlarge a modifying range of a concrete.
SOLUTION: A concrete base material 10 is placed in a hermetically sealed vessel 14 in a degassing treatment. In this treatment, a piping 12 is arranged so as to pass a connecting pipe part through the wall surface of the hermetically sealed vessel 14. A sealing material 16 is placed at the passing through part and air is removed from both the interiors of the piping 12 and the hermetically sealed vessel 14 to decompress both the interiors thereof. After the base material 10 is sufficiently degassed, an impregnant 20 is charged into the hermetically sealed vessel 14 and pressurized while keeping the interior of the piping 12 in the decompressed state. When the impregnant 20 is impregnated under these conditions, the impregnation range of the impregnant 20 is increased in depth, because the gas-permeable piping 12 is buried in the interior of the concrete base material 10 to perform the degassing from this part and the impregnant 20 is pressurized while keeping the piping in the degassed state.

PURPOSE: To produce the ceramics sintered body having holes by laminating plural sheets of green sheets which consist of a ceramics material, are formed with fine line patterns on the surface and are packed with the ceramics material between the fine line patterns, then dissolving away the fine line patterns and calcining the green sheets.
CONSTITUTION: An org. binder, such as polyurethane, having excellent alkali resistance and a plasticizer, such as dioctyl phthalate, are added to powder of ceramics, such as alumina, zirconia and magnesia, and the mixture is kneaded and molded to form the green sheet 1. The fine line patterns 2 consisting of a photosensitive resin compsn. which is easily soluble in an alkali soln. are formed on the surface thereof and, thereafter, the surface of the green sheet 1 is coated with a material 3 for forming holes essentially consisting of the ceramics material. Plural sheets of such sheets are laminated and compression bonded to form a laminate 4. The laminate is then treated with the alkali soln. to dissolve away the fine line patterns 2 and to form the holes 5 where the patterns are removed. This laminate is heated in a heating furnace and is degreased and calcined. The ceramics sintered body having the holes 5 in which the residues of the sintering do not remain is thus produced.

PURPOSE: To prevent the release of a surface layer due to the thermal shock or local external force and to obtain the title durable formed body by unidirectionally arranging plural extruded looped coils of an inorg. material on a plane, and joining adjacent coils to a specified length.
CONSTITUTION: A porous inorg. material (e.g., zeolite) is added with a binder (e.g., CMC), and kneaded. The mixture is extruded in the form of a loop while moving an extruding die in the arranging direction 4. The obtained strand 3 is looped, and sent onto a planar receiving surface. The centers of the plural coils 1 are shifted with the specified arranging pitch in the arranging direction 4 to arrange the coils. Plural coils 1 are partly overlapped, and a coil array 2 arranged in the arranging direction 4 is formed. Plural coil arrays 2 are arranged in parallel on one plane to form one layer, and plural layers are laminated and solidified. The coils of the adjacent coil arrays are overlapped to a length greater than the diameter of the strand and of ≤1/2 times the coil diameter, and joined.
