RAW MATERIAL AND MANUFACTURE FOR BUILDING FINISHING WALL MATERIAL

摘要

PROBLEM TO BE SOLVED: To take measures against a thick house by using an unprocessed prototype of dry shirasu as a raw material, and mixing the dry shirasu with white cement or gypsum, reinforcing material, such as thatch fibers for plastering or hemp, and pigment colorant, as composition. SOLUTION: Drying shirasu A of 80%, which is dried after removal of impurities, and mixed with white cement or gypsum B of 15%, reinforcing material C of 4%, such as thatch fibers for plastering or hemp and pigment colorant D of 1% as composition. The material formed like paste by adding an appropriate amount of water to the composition, and kneading it, is applied to the substrate 2 of a gypsum board, a veneer board, a concrete plate, an asbestos board or the like by a trowel or the like. The applied material is cured, it is subjected to surface finishing processing with various types of designs which is improved by giving various ideas to the finish design of the surface, and it is dried. In the case of curing it with the white cement or gypsum B, it is mixed in proportional rate of 1 to 1.5 of the white cement B to 4 of the drying shirasu A, or 1.5 to 2 of the gypsum B to 4 of the drying shirasu A. It is thus possible to attain energy saving and non-pollution.
