Abstract

플라스틱 혼합물의 조성을 토대로 개별 플라스틱의 분해특성으로부터 혼합물의 분해 성향을 추정하고자 하였다. 혼합물에 따른 개별시료 분해의 촉진이나 억제 효과는 관찰되지 않았으며 대부분 혼합물의 열분해결과는 개별성분의 분해결과를 단순합산함으로써 알 수 있을 정도였다. 그러나 열분해 온도는 혼합물 중 개별시료의 양이 아닌 혼합물 전체의 양에 따라 결정되어 가열시 하나의 용융체를 이루는 한 개별시료의 양보다는 시료전체의 양이 중요함을 보여주었다.

Pyrolytic propensity of plastics mixture was estimated in terms of those of individual plastic components. General trends of pyrolysis of plastics mixture could be depicted by simple addition of those of individual components without considering any particular synergistic or inhibition effects. However, pyroly-sis temperatures of individual components in the blend were edtermined by the weights of components corresponding to the whole blend, not by the real weights of individual components in the blend. More important was the weight of the whole sample, rather than the weight of each component, in a sampling pan because all thermoplastics in the pan would melt and agglomerate when heated.
