초록

이 연구에서는 암모늄염을 처리한 리기다 소나무의 연소성을 시험하였다. 실온에서 3종류의 암모늄염 즉, 황산암모늄, 제1인산암모늄, 그리고 제2인산암모늄의 20wt% 수용액에 각각 리기다 소나무를 함침시켜 건조시킨 후 콘칼로리미터(ISO 5660-1)를 이용하여 그의 연소성을 시험하였다. 암모늄염으로 처리한 시험편은 처리하지 않은 시험편에 비하여 그의 연소성을 감소 시켰다. 이것은 연소 억제성이 순수 리기다 소나무 시험편에 처리한 암모늄염 때문에 향상된 것으로 생각된다. 또한 암모늄염으로 처리한 시험편은 처리하지 않은 시험편에 비해 낮은 최대열방출률과 낮은 총방출열량을 나타내었다.

This study was performed to test the combustive properties of Pinus rigida-based materials by the treatment of ammonium salts. Pinus rigida plate was soaked in three 20 wt% ammonium salt solutions such as ammonium sulfate (AMSF), monoammonium phosphate (MAPP), and diammonium phosphate (DAPP), respectively, at the room temperature. After drying specimen treated with chemicals, combustive properties were examined by the cone calorimeter (ISO 5660-1). Comparing with virgin pinus rigida plate, specimens treated with the ammonium salts had lower combustive properties and It is supposed that the combustion-retardation properties improved due to the treated ammonium salts in the virgin Pinus rigida. Also, the specimens with treated ammonium salts showed both the lower peak heat release rate (PHRR) and lower total heat release (THR) than those of virgin plate.
