The raw material basically consists of hydraulic gypsum powder, calcium silicate powder and water. As the hydraulic gypsum powder and granules, at least one kind of gypsum powder and granules selected from natural gypsum and chemical gypsum is calcined, that is, hemihydrate gypsum, anhydrous gypsum and the like are used. As the calcium silicate powder, a powder containing at least one of xonotlite, tobermorite, fossiade and CSH is used.

If the particle size of the powder is less than 1 μm, the amount of water required for mixing with the water-setting gypsum powder increases, and as a result, the mechanical properties of the finally obtained humidity control material are improved. descend. On the contrary, if the particle size exceeds 3 mm, the moldability with the water-curable gypsum becomes poor.

る。This gypsum board exerts humidity control performance by the following action. That is, although calcium silicate is used as a raw material in the first and second invention methods of the present invention, when the calcium silicate is carbonated, as described above, calcium silicate has silica gel and calcium carbonate having a skeleton structure. Changes to. Silica gel has a property of taking in water molecules or releasing once-taken water molecules in its skeletal space depending on the humidity of the atmosphere in which it is placed.

工効率の向上に寄与する。Since the gypsum board of the present invention has such a skeletal space, when the board is used as a wall material of a building, for example, the wall material constitutes an exposed surface of a closed atmosphere having high humidity. If so, it adsorbs water molecules in the atmosphere to reduce the humidity in the closed atmosphere. On the contrary, when the wall material once adsorbing the moisture is exposed to the low-humidity closed atmosphere, the adsorbed water is released to increase the humidity of the closed atmosphere. The humidity-controlled gypsum board according to the present invention thus exhibits the moisture absorption performance. Further, since the gypsum board is mainly composed of gypsum, it is lightweight and excellent in workability, and contributes to improvement in construction efficiency when it is constructed as a wall material for a building.
