METHOD FOR PRODUCING INORGANIC BOARD, AND INORGANIC BOARD
PROBLEM TO BE SOLVED: To provide a method for producing an inorganic board high in fire resistance.SOLUTION: Provided is a method for producing an inorganic board comprising: a base material part forming step; a surface layer part forming step; and a curing step. In the base material part forming step, a base material part is formed from slurry including a cement-containing base material and water by a papermaking method. In the surface layer part forming step, a cement-containing surface layer material is scattered on the unhardened base material part to form a surface layer part. In the curing step, an unhardened inorganic board in which the surface layer part is formed on the base material part is cured. The base material comprises mica by 8 to 12 mass%, and the surface layer material comprises mica by 8 to 12 mass%.SELECTED DRAWING: Figure 1
【課題】耐火性の高い無機質板の製造方法を提供する。【解決手段】無機質板の製造方法は、基材部形成工程と、表層部形成工程と、養生工程とを含む。基材部形成工程では、セメントを含む基材材料と水とを含有するスラリーから抄造法により基材部を形成する。表層部形成工程では、未硬化の基材部の上にセメントを含む表層材料を散布して表層部を形成する。養生工程では、基材部上に表層部が形成された未硬化の無機質板を養生する。基材材料はマイカを８〜１２質量％含有するとともに、表層材料はマイカを８〜１２質量％含有する。【選択図】図１
