Abstract
Official abstract text for this publication.
A gypsum panel includes a gypsum core containing a termiticide with poor water solubility, wherein the gypsum core has a first end region, a center region, and a second end region having an equal thickness and extending along a thickness direction from one surface side to another surface side, the termiticide is contained in each of the first end region, the center region, and the second end region, and a content of the termiticide in the center region is lower than a content of the termiticide in the first end region and in the second end region.
First claim
Opening claim text (preview).
The invention claimed is: 1. A gypsum panel comprising a gypsum core containing a termiticide with solubility in water of 1 mass % or less, wherein the gypsum core has a first end region, a center region, and a second end region having an equal thickness and extending along a thickness direction from one surface side to another surface side, the termiticide is contained in each of the first end region, the center region, and the second end region, and a content of the termiticide in the center region is lower than a content of the termiticide in the first end region and in the second end region. 2. The gypsum panel according to claim 1 , wherein a content of the termiticide per 1 cm 3 of the gypsum core is greater than or equal to 0.1 μg and less than or equal to 330 μg. 3. The gypsum panel according to claim 1 , wherein a content of the termiticide per 1 cm 3 of the gypsum core is greater than or equal to 0.1 μg and less than or equal to 180 μg.
