난연약제 흡수량에 따른 국산 침엽수재의 연소특성

Combustion Characteristics of Domestic Softwoods According to the Amount of Flame Retardant Absorption

This study was conducted to decrease the combustibility of wood for the promotion of wood use, which is emerging as a way to reduce greenhouse gas emissions. As materials, red pine, Japanese larch, and Korean pine, which are major conifers used in Korea, were selected. And, the phosphorus-based flame retardant was injected into the test specimens. Then, the peak heat release rate (PHRR) and total heat release (THR) were measured through the cone calorimeter test. As a result, it was concluded that the minimum amount of flame retardant absorption was 139 kg/m³ for incombustible material and 178 kg/m³ for semi-noncombustible material based on the regression curve between total heat release and the amount of flame retardant absorption.
