  • 요업 소성로에서 내화재로 흡수된 에너지는 피가열물에 방사열로 작용하며, 이때 내화물의 방사율이 높을수록로내의 온도를 상승시켜 소비되는 연료가 절감된다. 따라서 내열성과 방사율이 높은 세라믹 내열도료를 개발하여 구성물의 결정 구조, 열적특성, 적외선 방사량 및 에너지 절감실험에 대한 데이터를 분석한 결과 높은 내열성과 적외선 방사량 증가에 따른 에너지 절감에 효과가 있음을 알 수 있었다.

  • Applying fire resistive coating to steel members is one of the general methods to secure fire resistance performance of steel members. And intumescent coating system is currently one of methods giving fire resistance to steel members. Intumescent coating system for fire resistance, however, has undesirable weaknesses that fire resistance performance of steel members is being deteriorated due to cracks and falling-offs of the coverings as time goes after completion of the coverings to the members. This study is designed to understand changes in fire resistance performance of intumescent coating system through follow-up tests on temperature of unexposed surface for the domestic intumescent coating system.

  • Polyester/melamine cured coatings had been used for pre-primed coatings and pre-coated metal coatings, because it has good mechanical,chemical properties, and mar resistance. But it has weak points such as stiffness and low formability for making automotive components. Polyester had been synthesized using polycarbonate diol of long alkyl chain which can improve flexibility and formability which is one of the important factors for pre-coated steel sheets (PCM). In this study, strain and tensile strength were examined by the tensile test and formability was examined by the drawing test. Also, Those polyester resins were also measured by DMA to verify flexibility of cured coatings.

  • High performance concrete(HPC) has been widely used in high-rise building. The HPC has several benefits including high strength, high fluidity and high durability. However, spalling is susceptible to occur in HPC and HPC also tends to be deteriorated in the side of fire resistance performance at fire. This paper investigated the spalling prevention of high performance RC column. Control concrete showed severe failure and a case of concrete with fire enduring spraying material exhibited more severe spalling failure than even control concrete. In addition, concrete with fire enduring paint reported the most favorable spalling resistance effect for preventing spall, compared with other concrete covered with finishing materials, such as fire enduring spraying material, gypsum board, marble board and fire enduring PC board. Meanwhile, concrete adding 0.1% of PP fiber demonstrated spalling resistance performance after 3hours load bearing test.
