摘要： A method of cooling board materials of inorganic substance wherein after aging treatment in an autoclave using saturated steam of high temperature and high pressure, the board material is left in the autoclave and the pressure therein is reduced to less than one atmosphere, and then the reduced pressure is retained at a stationary state until the temperature of the board material falls to about the temperature at which water does not boil, and then removing the board material from the autoclave. The board material may also be subjected to a drying treatment by alternately supplying saturated steam and reduced pressure after aging and prior to cooling.

摘要： A method of producing an inorganic substance board, wherein after preparation, such as by use of paper making process, the board is hardened in an autoclave with saturated steam at a high temperature, high pressure and for a suitable length of time, and after hardening, subjecting the board to one or more drying cycles comprising a vacuum treatment at 60 to 300 Torrs, for a suitable length of time to enable the core of the board to reach a suitable temperature, the application of saturated steam at 2 to 12 Kg/cm.sup.2 pressure and 120 to 190.degree. C temperature for a period of time sufficient to allow the core to reach a suitable temperature. The number of cycles is preferably 10 or less. Advantageously, the inventive drying treatment prevents efflorescence and warping of the boards.
摘要翻译：一种制备无机物质基板的方法，其中在制备之后，例如通过使用造纸过程，将板在高压釜中在饱和蒸汽中在高温，高压和合适的时间内硬化，并且在硬化之后将板进行一个或多个干燥循环，包括在60至300托的真空处理合适的时间长度以使板的芯达到合适的温度，使用饱和蒸汽在2至12Kg / cm2压力和120至190℃的温度持续一段足以允许芯达到合适温度的时间。循环次数优选为10以下。有利地，本发明的干燥处理防止板的风化和翘曲。
