段として（表 以下のような防湿方法がとられていた。[Prior Art] The underfloor areas of traditional Japanese houses had no partition wall between them and the outside, allowing for good ventilation and preventing moisture from accumulating.On the other hand, modern houses have partition walls between the floors and the outside, making it easy for moisture to accumulate under the floors. When moisture accumulates under the floor, the wood used as building material is more likely to rot. In addition, high humidity makes it easy for pests such as white bark mites to inhabit, causing damage to houses and harming humans. Conventionally, moisture-proofing methods such as those shown in the table below have been used to remove this moisture.

従来存在しなかった。However, when using the moisture-proofing methods (2) and (3) above, there is a problem that the moisture-proofing effect is not very effective because the material with sufficient moisture absorption effect is not used. When moisture-proofing methods are used, although a sufficient moisture absorption effect can be obtained, it takes time to spread the desiccant powder evenly, and there are problems such as the powder scattering. Conventionally, nothing has been done to solve these problems. In addition, on the inner walls of condominiums, etc., condensation occurs due to the temperature difference with the outside in winter, and the moisture can cause mold to grow on the walls, and household goods placed near the walls may get wet and become damaged. To solve this problem, heat insulating material was glued to the inner surface of the outer wall without any gaps, preventing cold temperatures from outside from reaching the inner wall surface and preventing condensation. However, with the above-mentioned dew condensation prevention treatment, dew condenses on areas where there is no adhesive between the exterior wall and the insulation material, and the moisture causes the insulation material to peel off from the exterior wall.As a result, the insulation material peels off from the exterior wall. There were problems such as dew condensation on the inner surface getting worse and the insulation effect being lost and condensation forming on the inner wall surface.Therefore, it was necessary to remove the moisture caused by the condensation that formed between the outer wall and the insulation material. Asahi: Since ventilation is not possible in such places, it is considered appropriate to dehumidify using a desiccant agent. Therefore, conventionally, no measures have been taken to dehumidify the inside of the wall, such as between the outer wall and the insulation material. Desiccant agents are considered suitable for dehumidifying areas that cannot normally be ventilated, such as buildings. The means are

The purpose is to easily and efficiently dry the area under the floor by placing it under the floor, and by attaching it to the inside of the outer wall of an apartment building, it easily absorbs condensed moisture and prevents damage caused by condensation. .

It has the effect of promoting moisture absorption by allowing silica gel to absorb moisture. However, if the amount of alkaline earth metal halide blended is too large, the amount of liquid produced by deliquescence may exceed the amount that can be adsorbed by silica gel. Therefore, the amount of alkaline earth metal halide added must be 20% by weight or less based on the silica gel.

Under the above-mentioned humidity of 90%, it shows a water adsorption amount of 33% by weight, whereas the water adsorption amount of conventional building materials such as Ceracola and concrete under the same conditions is 3 to 10% by weight. It can be seen that the moisture absorption effect is excellent. In addition, since it contains fibrous materials such as sawdust chips, it is possible to obtain a hygroscopic molded product that is durable and resistant to cracking. Moreover, since the shape of the hygroscopic molded body is a small tile shape of 8 to 15 cm square, it is hard to bend due to external force and is strong.

８時間放置しノー後の水分吸着量を示すグラフである。That is, after a solution of an alkaline earth metal halide is adsorbed onto silica gel, it is dried at about ]0°C for about]0 hours. The concentration of the solution is 10%,
In addition, the amount used was 10% by weight based on the silica gel.Also, as the alkaline earth metal halide (Rushium chloride was used). In this example, the processed silica gel described above was used instead of silica gel as a component of the highly hygroscopic molded body, so the alkaline earth metal halide deliquesced due to moisture in the air. The resulting liquid is adsorbed by the silica gel constituting the hygroscopic molded body.As a result, moisture absorption is promoted and a hygroscopic molded body with quick moisture absorption performance can be obtained.Figure 9 shows the hygroscopic properties of this example. The molded body was cut into 1 cm square pieces and placed at relative humidity of 20%, 50%, 70% and 90%.
It is a graph showing the amount of water adsorption after being left for 8 hours.

If condensation occurs inside the wall, such as between the hygroscopic molded body 2 or between the hygroscopic molded body 2 and the interior material 27, the moisture is immediately absorbed by the hygroscopic molded body 2. The molded body 2] and the interior material 27 can be prevented from peeling off. Also,
Due to the heat insulating effect of the hygroscopic molded body 21, dew condensation on the surface of the interior material 27 can be prevented. In addition, if the interior material 27 is, for example, moisture-permeable wallpaper, even if dew condensation occurs on the surface of the interior material 27, the moisture will be absorbed by the hygroscopic molded body 21, causing mold and damage to household goods. Damage caused by condensation can be prevented. In addition, the interior material 27 is the hygroscopic molded body 2]
By pasting it on top of the wallpaper, residents have the advantage of being able to choose their favorite wallpaper from among a variety of conventional wallpapers.

In this way, since the hygroscopic molded body 2] absorbs the condensation generated inside the wall, the hygroscopic molded body 21,
Damage such as the crosspiece 29 coming off due to dew condensation can be prevented. In addition, since a layer of air is formed between the hygroscopic molded body 2 and the interior panel 31, the insulation effect of the wall can be further enhanced.
It is possible to prevent dew condensation from forming on the surface of the interior panel 31. Also,
It is possible to impart elasticity to the surface of the interior panel 31, and it is possible to improve soundproofing and the feel of the inner wall.
