WATER-ABSORBABLE BOARD AND MANUFACTURING METHOD THEREOF
To provide a water-absorbable board on which processing such as cutting is performed and which can improve a yield, and a manufacturing method thereof.SOLUTION: A water-absorbable board manufacturing method for manufacturing a water-absorbable board 1 containing a foamed glass material, includes: a dough making step S1 of mixing powdered glass foaming material, silica sand, slaked lime, and pulp with water to form slurry-like dough M; a plate-shaped dough forming step S2 of forming a slurry-like dough M into a plate of a predetermined thickness; a first drying step S3 of heating the dough M having been formed in a plate shape to be dried until water content reaches 40% or less; a hardening step S5 of heating the dough M having been dried while pressurizing it above atmospheric pressure to harden the same until the water content reaches 40% or less; and a second drying step S6 of drying the hardened plate-shaped dough M until the water content is reduced to 15% or less while being heated at a higher temperature than in the first drying step S3.SELECTED DRAWING: Figure 1
【課題】 切削などの加工を行うことができ、かつ歩留まりを良くすることのできる、吸水性ボードおよびその製造方法を提供する。【解決手段】 ガラス発泡材を含有する吸水性ボード１を製造する吸水ボード製造方法であって、粉末状にしたガラス発泡材、珪砂、消石灰およびパルプを水に混ぜてスラリー状の生地Ｍを作成する生地作成工程Ｓ１と、スラリー状の生地Ｍを所定の厚さの板状に形成する板状生地形成工程Ｓ２と、板状に形成された生地Ｍを加熱しながら含水量が４０％以下になるまで乾燥させる第１乾燥工程Ｓ３と、含水量を４０％以下まで乾燥させた生地Ｍを大気圧以上に加圧しながら加熱して固化させる固化工程Ｓ５と、固化させた板状の生地Ｍを第１乾燥工程Ｓ３より高温で加熱しながら含水量を１５％以下に乾燥させる第２乾燥工程Ｓ６とを有する。【選択図】 図１
