요약
이 연구에서는 4종의 암모늄염으로 도포된 베니어 시험편의 연소 특성을 시험하였다. 20 wt%의 암모늄염 수용액으로 각각 베니어 시험편에 3회 붓으로 도포하여 실온에서 건조시킨 후, 콘칼로리미터(ISO 5660-1, 2)를 사용하여 연소특성을 조사하였다. 그 결과, 모노암모늄 포스페이트(MAPP)와 디암모늄 포스페이트(DAPP)로 처리한 시험편은 순수한 베니어 시험편에 비해 평균열방출율($HRR_{mean}$)이 각각 6.7%, 10.0% 낮았다. 반면에 MAPP는 최대 일산화탄소발생속도($CO_{peak}$ production rate)가 순수한 베니어 시험편에 비해 15.7% 높았고 DAPP는 8.2% 낮았다. 황산암모늄(AMSF)으로 도포된 베니어 시험편의 최대 연기발생속도($SPR_{peak}$)는 순수한 베니어 시험편에 비해 9.6% 낮았고 DAPP로 처리된 시험편은 33.3% 낮았다. 또한 DAPP는 최대 연기비감쇠면적($SEA_{peak}$)에 다다르는 시간이 순수한 베니어 시험편에 비해 38.4% 지연되었다. 그러므로 DAPP는 베니어의 연소성질을 억제시키고 연기발생을 감소시키는 경향이 나타났다.
Abstract
This study tested the combustion characteristics of veneer specimens coated with four kinds of ammonium salts. Each veneer specimen was coated three times with 20 wt.% ammonium salt solutions at room temperature. After drying, the combustion characteristics of the specimens coated with chemicals, were investigated using the cone calorimeter (ISO 5660-1, 2). The specimens coated with monoammonium phosphate (MAPP) and, diammonium phosphate (DMPP) showed a 6.7% and, 10.0%, lower mean heat release rate ($HRR_{mean}$), respectively, than that of the uncoated specimen. On the other hand, the specimens coated with MAPP showed a 15.7% higher $CO_{peak}$ production rate and the specimens coated with DAPP showed by 8.2% lower rate than that of the uncoated specimen. The veneer coated with ammonium sulfate (AMSF) and DAPP showed a 9.6% and 33.3% lower the peak smoke production rate ($SPR_{peak}$) than that of the uncoated specimen. In addition, the time to the peak smoke extinction area ($SEA_{peak}$) was delayed by 38.4% in the specimens coated with DAPP than the uncoated specimen. Therefore, DAPP inhibited the combustion properties of the veneer and showed a tendency to reduce smoke production.
Key Words: Ammonium salts, Veneer, $CO_{peak}$ production rate, Peak smoke production rate ($SPR_{peak}$)
