短くすることとなっていた。2. Description of the Related Art The climate of Japan is humid due to the presence of the rainy season and the amount of rainfall throughout the year due to its geographical conditions. Is given. For example, the climate climate in Japan is extremely poor for buildings such as houses, especially under the floor, where the ground is humid due to moisture from the ground. If such high humidity conditions are maintained for a long period of time, dew condensation will occur under the floor, increasing the water content of the underfloor wood and the occurrence of rot fungi that will rot wood. In addition, it causes breeding and promotes deterioration of floor materials, and as a result, shortens the useful life of the entire house.

There is a problem that it is uncomfortable because it easily absorbs and retains moisture and worsens the flow of air.

除湿を行えないという欠点があった。Conventionally, various measures against moisture and drying have been used to prevent high humidity in the stored state of buildings such as houses and clothes. For example, in a house building or the like, it has generally been practiced to mix activated carbon into the ground or sand, hit concrete, or cover the ground with a vinyl sheet. However, sand and activated carbon have a temporary effect, and concrete absorbs water emanating from the ground, so that the effect cannot be expected so much. Vinyl sheets have a problem in durability. Some units forced ventilation under the floor using a ventilation fan, but there were problems with large-scale construction and installation locations. Furthermore, dehumidifiers containing a moisture absorbent such as calcium chloride for the purpose of moisture proofing and drying have been installed at the corners of the closet, and desiccants have been stored together with clothes and the like when they are stored. However, since the dehumidifier has to be small because it is limited by the arrangement space, the dehumidifying area is remarkably narrow and the dehumidifying capacity is small, and in the dehumidifier arranged in the corner of the room, it is generated from under the entire floor. There is a drawback that effective dehumidification cannot be performed against moisture.

解決されていない。[0006] As the desiccant, well-known desiccants include porous materials such as gypsum, silica gel, activated carbon, calcium chloride, zeolite, bentonite and the like. These porous materials can be used alone or in combination. And store them directly in a container or impregnate filter paper etc.
For example, it has been used for drying and dehumidifying in a room, in a clothing storage, and in a packaging bag for food or the like. As a technique as described above, there is a dew condensation preventing material manufactured by Japanese Patent Application Laid-Open No. 63-189492, "Method for manufacturing a dew condensation preventing material". This technology involves the steps of producing wood charcoal by steaming wood materials such as wood bark and wood pieces, processing this charcoal into fine powdered charcoal before relatively moistening, powdered charcoal that is relatively not wetted. Characterized by comprising a step of storing a predetermined amount in a paper or cloth packaging container having air permeability. Another technology is
Japanese Patent Application Laid-Open No. 2-229343 discloses a "wall and floor structure". This technology is a wall in which activated carbon is interposed in a gap between an outer wall material and an inner wall material, and the activated carbon is formed by stacking carbon fibers into a sheet-like body, and the carbon fiber sheet-like body is placed on the indoor side of the outer wall material. Alternatively, the wall structure is characterized in that the inner wall material is stretched and fixed over the entire exposed portion of the outdoor side surface.
However, conventionally known desiccants using these porous materials do not have a long-lasting drying effect, and after a certain period of use, the adsorption power of the carrier itself is saturated. There is a problem that the effect of drying and dehumidification after the time cannot be expected, that is, the desired performance cannot be maintained for a long time. Furthermore, these desiccants are usually installed in a cool and dark place, and the desiccant itself reaches a saturated state in a short time, and tends to be in a state of lack of regenerative property. As a result, there is a problem that frequent inspection and management is required during storage, such as dropping of water droplets, surface contamination, and the like, which may cause moisture. As another technique, Japanese Utility Model Application Laid-Open No. 63-10894.
There is the issue "desiccant". This technology uses a sheet-like desiccant 1
And a ceramic sheet 2 which emits far-infrared rays at room temperature, and is sandwiched by a film 3 to form a desiccant structure. This technique was developed with the focus on the fact that far infrared rays have the effect of improving the taste of food and preventing mold, but this technique can also maintain the above-mentioned disadvantages, that is, the desired performance for a long period of time. The problem of not having
The problem that frequent inspection and management is required during storage has not been solved.

し、この発明に到った。Means for Solving the Problems The inventor of the present invention focused on the fact that charcoal powder easily absorbs far-infrared rays. A far-infrared radiating substance is mixed with charcoal powder having characteristics of an internal surface area of 200 m 2 / g or more and a true specific gravity of 1.400 to 1.900 using a far-infrared radiating substance which has been attracting attention. The present inventors have found that providing the desiccant can completely eliminate the above-mentioned conventional disadvantages, and reached the present invention.

されてなることを特徴とする乾燥剤である。The desiccant according to the present invention has an internal surface area of at least 200 m 2 / g and a true specific gravity of 1.400 to 1.900.
It is a desiccant characterized by mixing a powdery far-infrared radiating substance with charcoal powder having the following characteristics.

Black charcoal using hinoki, oak, oak, etc., white charcoal using oak, etc., sawdust and sawdust obtained after pressurizing sawdust can be suitably used. Charcoal has an internal surface area of 2
Those having a true specific gravity of 1.400 to 1.900 or more with a specific gravity of at least 00 m 2 / g are preferably used. The true specific gravity as used herein means a true specific gravity according to a specific gravity bottle method. True specific gravity is 1.400 to 1.90
In the case of 0, the volume is about 0.4 to 1.2.

重は１．４００〜１．９００が好ましい。The reason why the above-mentioned properties are preferable as charcoal properties is as follows. That is, an internal surface area of 200
The reason for setting it to m 2 / g or more is that if it is less than 200 m 2 / g, moisture absorption and adsorption are low, and for example, under a floor, moisture protection and drying of the space above the floor may not be performed sufficiently. On the other hand, in the case of 200 m 2 / g or more, there is no such defect. In addition, since the charcoal powder having a true specific gravity of less than 1.400 is soft, if a powdery far-infrared radiating substance is blended, the charcoal powder is crushed by the far-infrared radiating substance to become a fine powder, and cannot be uniformly blended. . In addition, charcoal powder having a true specific gravity of more than 1.900 is too hard to handle and difficult to mix uniformly, so that the true specific gravity is preferably 1.400 to 1.900.

This is because the charcoal suitably absorbs the far infrared rays emitted by the far infrared radiating substance. Charcoal that has absorbed far-infrared rays is easily dried after absorbing moisture and can be used semipermanently as a desiccant. The charcoal used in the present invention is defined as "charcoal powder" because "charcoal powder" is excellent in hygroscopicity and adsorptivity. In other words, "charcoal powder" or "pulverized coal" has the property of adsorbing various gases and liquids very well because it is porous and has a large internal surface area and has good air permeability, and is a substance suitable for dehumidification and drying. It is.

However, specific examples thereof include ceramic powder mainly composed of zirconia-based, alumina-based, titanium-based, cobalt-based, and the like. Further, the form of the far-infrared radiating substance is suitable in that powder or pulverized material is easily mixed with charcoal powder.

限定されるものではない。The reason for using a far-infrared ray radiating substance in the present invention is that it has excellent dehumidifying and drying properties. In other words, among infrared rays (wavelength 0.76 to 1000μ), the wavelength of long wavelength (4 to 1000μ) is almost the same as the wavelength absorption characteristics of organic substances, so the reflection and transmission of energy is small, and the energy is almost absorbed by charcoal powder. It is a substance that has high transfer efficiency and has been widely used in methods such as drying in recent years. The compounding amount of the far-infrared ray emitting substance may be set according to the type of far-infrared ray emitting substance to be used, and is not particularly limited.

It is a desiccant that can provide excellent dehumidification and drying effects. That is, the desiccant according to the present invention efficiently reduces humidity in a high-humidity environment due to the interaction between the moisture absorbing action of the charcoal powder and the drying action of the powdery far-infrared radiating substance.

The far-infrared radiating substance powder is contained in the desiccant in a form mixed with the charcoal powder, so the contact area between the charcoal powder and the far-infrared radiating substance powder is large, and far-infrared rays are absorbed more efficiently by the charcoal powder Is done. For this reason, the drying of the charcoal powder is promoted, and there is no problem that the adsorption power of the charcoal powder itself becomes saturated and has only a short-term performance maintaining power as in the above-mentioned disadvantages of the prior art, and the charcoal powder has a long-term or almost permanent Period performance can be maintained.
