Abstract

Sound absorption capability of the flame resistant treated sawdust-mandarin peel composite particleboard was were estimated by two microphone transfer function methods. The weight of flame resistant treated board slightly increased by the treatment. The treatment improved fire retardant performance by decreasing the charred area of flame resistant treated board. Sound absorption capabilities of flame resistant treated sawdust-mandarin peel composite particleboard, in the entire estimated frequency range of 500-6,400 Hz was slightly lower than those of the control specimen. Sound absorption capability of both the control and flame resistant treated sawdust-mandarin peel composite particleboards were higher than that of commercial gypsum boards, being widely used as a sound absorber for ceiling at the estimated frequency.

방염처리에 의한 톱밥-귤박 혼합파티클보드의 방염성능과 흡음성능의 변화를 관찰하고자 톱밥과 귤박을 혼합하여 파티클보드를 제작하였다. 보드로부터 원반형 시험편을 제작하여 무처리 보드에 2마이크로폰 전달함수법으로 보드의 흡음률을 측정하고 동일한 시험편에 방염수지를 도포한 후 동일한 방법으로 흡음률을 측정하였다. 방염성능 시험은 무처리와 방염처리 톱밥-귤박 혼합파티클보드를 45도 연소챔버에서 연소하여 탄화면적을 비교하였다. 방염처리에 의해시험편의 중량은 6.3% 정도 증가하였으며 탄화면적은 46.7% 정도 감소하였다. 흡음률은 측정주파수범위(500-6,400 Hz) 에서 방염처리 시험편이 무처리 시험편보다 약간 낮게 나타났다. 무처리와 방염처리 톱밥-귤박 혼합파티클보드의 흡음성능은 측정주파수 영역에서 상용 석고보드(두께 11 mm)보다 우수한 흡음성능을 나타내어 비내력벽 등의 흡음판으로의 이용이 기대된다.
