It is baked at 0°C and made into tiles with a humidity control function. Figure 6 shows Wakkanai diatomaceous earth crushed and mixed with water to make it into a kneaded soil shape.
After kneading and molding the clay, it is fired at 800°C and made into a tile shape, which has a humidity control function. Figure 7 shows the humidity control function of a mixture of crushed Wakkanai diatomaceous earth and stoneware clay from Asahikawa, Hokkaido, which is used as a raw material for clay ceramics, dry press molded into a tile shape, and then fired at 800°C. In this way, by using Wakkanai layer pulverized diatomaceous earth alone or blending it with other ceramic raw materials, it is possible to easily produce a variety of ceramics with humidity control functions without changing the conventional production process. Moreover, as can be seen from FIG. 7, this humidity control function is uniquely controlled by the mixing ratio of Wakkanai diatomaceous earth, and its control is extremely easy.

There are gypsum-based, cement-based, resin-based materials, etc. that are characterized by non-fireability. For example, Fig. 8 shows the expression of humidity control function when Wakkanai diatomaceous earth was added to gypsum. . By adding this Wakkanai layer diatomaceous earth to gypsum that does not have a humidity control function, it can exhibit a humidity control function. Also,
The greater the amount added, the greater the humidity control function. By compounding Wakkanai Formation diatomaceous earth as a filler with other materials, the pores are blocked and the humidity control function is expressed, so long as the humidity control function is not lost, it is characterized by non-firing. A wide variety of humidity control functions can be easily manufactured.

。[Effects of the Invention] Since the present invention is constructed as described above, it produces the following effects. A. The humidity control material using Wakkanai diatomaceous earth of the present invention absorbs and releases moisture according to changes in humidity, and in particular, humidity of 50% is considered to be a comfortable living environment.
It has the property of absorbing moisture significantly above RH. This makes it possible to create a comfortable living environment where dew condensation and the growth of mold and mites can be prevented. B. Wakkanai diatomaceous earth is characterized by its porous structure of silica, so it is expected to have various functions such as adsorption ability and catalytic ability in addition to the above-mentioned humidity control function. Furthermore, due to its characteristics as a chemically and thermally stable mineral, it has a wide range of uses, and is considered to be the subject of research from a wide range of fields as a functional raw material. C. Furthermore, the present invention utilizes natural inorganic resources that are widely distributed in Hokkaido, especially the depopulated Tenboku region, and will greatly contribute to the promotion of locally-based industries and the revitalization of depopulated areas. It is.
