METHOD FOR MOLDING HEARTWOOD OF INCOMBUSTIBLE HEAT INSULATING PANEL AND MANUFACTURING METHOD FOR INCOMBUSTIBLE HEAT INSULATING PANEL

摘要

The purpose of the present invention is to facilitate the treatment of heartwood which is formed by aligning multiple heartwood blocks where the extension direction of a fiber follows the thickness direction, and to facilitate fixation work on both faces of a metal plate. Multiple heartwood blocks (10) cut from rock wool (1) are arranged in a row while the extension direction of a fiber (1a) follows the thickness direction; a first heartwood block layer (21) is formed by coating an adhesive (25) on the upper surface thereof; a second heartwood block layer (22) is formed by laminating the multiple heartwood blocks (10), while the extension direction of a fiber (1a) follows the thickness direction, on the upper surface of the first heartwood block layer (21) in a zigzag or a pound (#) shape; and heartwood (20) is obtained by pressing the laminated heartwood block layers (21, 22) in the thickness direction.;COPYRIGHT KIPO 2014
