摘要
PROBLEM TO BE SOLVED: To make possible a formation of even a small curved surface in a short time, by setting the parallel tensile strength of original piper, surface density and thickness of a board within a specified range in a building board made by covering a core material made of mainly gypsum by base paper. ;SOLUTION: In a building board A made by covering a core material 1 made of mainly gypsum with base paper 2, the parallel tensile strength of either of the front or the rear surface of base paper 2 is set at 5 to 12kgf, the surface density as a board at 2.4 to 7.65kg/m2 and the thickness as a board at 4 to 9mm. The fragility of a gypsum board lacking in toughness is reduced by making fibers exist in the core material. The amount of the fibers added shall be up to 3.5 pts.wt per 100 pts.wt. calcined gypsum, preferably in a range of 0.1 to 3.0 pts.wt. or more preferably in a range of 0.5 to 2.5 pts.wt. The shape of the fibers should be 5 to 13μm in diameter and in a range of 3 to 25mm or more preferably in a range of 10 to 20mm in length.;COPYRIGHT: (C)1997,JPO
