CORE MATERIAL, GYPSUM BOARD AND METHOD FOR PRODUCING CORE MATERIAL
To provide a core material that prevents the problem of difficulty in screwing in a screw, while maintaining a high specific gravity, a gypsum board including the core material and a method for producing a core material.SOLUTION: A core material is predominantly composed of gypsum. In the core material, the relationship between a compression strength y (N/mm2) and a specific gravity x satisfies the following formula (1). Preferably, the compression strength is 2.0 N/mm2 or more, and it contains crystals having a length of 50 μm or more in their cross sections. (1) y≤0.9393×e2.6372x-0.3.SELECTED DRAWING: Figure 3
【課題】比重を高い状態に維持しつつビスが入り難いという問題が生じにくい芯材、当該芯材を用いた石膏ボードおよび芯材の製造方法を提供する。【解決手段】石膏を主成分とする芯材であって、圧縮強度ｙ（Ｎ／ｍｍ２）と比重ｘとの関係が、以下の式（１）を満たし、好ましくは、圧縮強度が２．０Ｎ／ｍｍ2以上であり、断面において５０μｍ以上の長さを有する結晶を含む、芯材。（１）ｙ≦０．９３９３×ｅ２．６３７２ｘ−０．３【選択図】図３
