AUTOCLAVE CURING METHOD FOR CEMENT PLANAR MATERIAL

摘要

PURPOSE:To prevent an occurrence of a crack in corner parts of upper ones of stacked green sheet-form cement planar materials when a large number of cement planar materials are placed on a pallet and cured in an autoclave. CONSTITUTION:A large number of cement planar materials 1 are placed on a pallet 2 and cured in an autoclave 3. A shielding plate 6 with shielding downward pieces 5 provided at the outer end parts thereof and projected downward IS placed on an uppermost cement planar material 1 through an auxiliary plate 4 made of the same material as the cement planar material 1. The side end faces of upper ones of the many cement planar materials 1 placed on the pallet 2 are covered with the shielding downward pieces 5. In this state, the cement planar materials 1 are cured in the autoclave 3.
