METHOD FOR MANUFACTURING SOUND ABSORBENT YELLOW SOIL-BASED TILES, CAPABLE OF OBTAINING SOUND ABSORBENT EFFECT WITHOUT AN ADDITIONAL SOUND ABSORBENT MATERIAL

摘要

PURPOSE: A method for manufacturing sound absorbent yellow soil-based tiles is provided to apply sound absorbent effect to the yellow soil-based tiles by forming pores in the yellow soil-based tiles using bay salt.;CONSTITUTION: Yellow soil is formed into a plate-shaped yellow soil-based tile(10). Bay salt(20) is arranged at the bottom side of a frame(30). The yellow soil-based tile is arranged on the upper side of the bay salt. The upper side of the yellow soil-based tile is continuously pressurized, and the yellow soil-based tile on the bay salt is naturally dried. While the bay salt is melted, pores are formed in the yellow soil-based tile.;COPYRIGHT KIPO 2011
