Density and Thermal Conductivity Property of the Lightweight Composite Panel Core According to Pearlite Replacement ratio

펄라이트 치환율에 따른 경량복합패널 심재의 밀도 및 열전도율 특성

Recently, in the apartment house of our country, office building, apartment, and etc, the lightweight composite panel is much used as the partition wall body. This is due to be very convenient when the execution and dismantling is convenient and it forms the space which the consumer in the space desires. Therefore, in this research, the thermal conductivity property of the lightweight composite panel core according to the replacement ratio variation of the pearlite tries to be analyze. As the density test result and replacement ratio of the pearlite increased, the density showed the tendency to rise. the replacement ratio of the pearlite increased, the absorption rate showed the tendency to fall. And this is determined that absorption rate is degraded due to the increase in the density. the thermal conductivity test result and pearlite replacement ratio increased, the tendency that the thermal conductivity increases was represented.
