METHOD FOR DETECTING VOIDS IN GYPSUM-BASED CONSTRUCTION BOARD AND METHOD FOR PRODUCING GYPSUM-BASED CONSTRUCTION BOARD

摘要

The method of detecting the voids in the gypsum-based building board includes contacting a cooling medium with the surface of the gypsum-based building board generated by hydration reaction of calcined gypsum to cool the surface, and after the cooling is completed, the gypsum-based building board And detecting the temperature distribution on the surface.
