INORGANIC BOARD AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently producing an inorganic board in which the surface of a plate-like hydraulic inorganic material is covered with a surface layer material. SOLUTION: This production method for the inorganic board comprises setting a plate-formed base consisting mainly of a hydraulic inorganic material on the upper surface of a lower die and then press-forming the base using both upper and lower dies to form the surface of the base into a prescribed shape. In this case, many material-feeding holes are bored on the approximately whole pressing face of the upper die, and the surface layer material is fed on the surface of the base set on the lower die from the material feeding holes in such a state that the above pressing face stands close to the base surface.
