요약
본 연구는 ABC 분말소화약제와 제1인산암모늄의 열분해생성물이 목재표면에 미치는 영향에 대해 검토하였다. 목재표면에서 열분해 생성물을 제거하였을 때 제1인산암모늄은 점도가 높은 투명한 열분해 생성물이 눌어붙어 제거하기 힘들었으나 ABC 분말소화약제는 덩어리진 형태로 쉽게 제거되었다. 열분석 결과 각 시료의 열분해 특성은 유사하나 열분해 잔존물의 중량이 ABC 분말소화약제는 55.9%, 제1인산암모늄은 25.2%로 나타나 차이를 보였다. ABC 분말소화약제에 첨가된 첨가제가 열분해 잔존물의 중량 및 메타인산의 방신효과에도 영향을 미치는 것으로 나타났다.
Abstract
This study the effect of pyrolysis products ABC dry chemical and of monoammonium phosphate on wood surface. When the pyrolysis product was removed from the wood surface, monoammonium phosphate was removed due to the high viscosity of the transparent pyrolysis product, but the ABC dry chemical was removed in a lump form. Thermal analysis showed that the pyrolysis characteristics of each sample were similar but the weight of pyrolysis residue was 55.9% for ABC dry chemical and 25.2% for monoammonium phosphate. The additives added to the ABC dry chemical also affect the weight of the pyrolysis residue and the fire protection effect of metaphosphoric acid.
Key Words: Metaphosphoric acid, ABC dry chemical, Monoammonium phosphate
