Calcium silicate board and method of manufacture therefor |
摘要 |
<p>The object of the present invention is to improve the overall strength and interlaminar strength of a compact (green sheet) before hydrothermal reaction by using alunites, alums and aluminum sulfate having a specified specific surface area which does not require the addition of a setting retarder or a curing accelerator together with a curing agent in order to provide a method of manufacture for a lightweight calcium silicate board which does not give rise to interlaminar peeling or bursting during hydrothermal reaction and to provide such a calcium silicate board. The method of manufacture for a calcium silicate board according to the present invention is characterized by use of one or more species selected from alunites and alums with a Blaine specific surface area of 4000 cm<2>/g or more or aluminum sulfate with a Blaine specific surface area of 2000 cm<2>/g or more.</p> |
