Abstract

In this paper, We produced supporting for ginseng cultivation facilities as a material recycling product of CPW(Complex Plastic Wastes, CPW) from households. And we analyzed the characteristics of material recycling products according to the amount of r-LDPE(Recycled low density polyethylene, r-LDPE) used. As a result, as the amount of recycled LDPE used increa sed, the tensile strength a nd elonga tion of ma teria l recycled products using CPW increa sed, but a sh decrea sed. When the recycled r-LDPE usage is 5% or more, the physical properties of the material recycling product using CPW stably satisfy the quality standard (GRM 3093-2021) of supporting for ginseng cultivation facilities.

본 논문은 생활계 복합재질 폐플라스틱을 재활용한 물질재활용 제품의 물성을 향상시키기 위한 방안으로서 단일 재질 폐플라스틱인 r-LDPE(Recycled Low Density Polyethylene, r-LDPE) 사용량을 변화시켜 물질재활용 제품의 물성을 평가·분석하였다. 그 결과 r-LDPE 사용량이 증가할수록 생활계 복합재질 폐플라스틱 물질재활용 제품의 인장강도, 연신율은 증가하는 경향을 나타내었지만 회분은 감소하는 경향을 나타내었다. 생활계 복합재질 폐플라스틱 재생원료에 r-LDPE 사용량을 5% 이상 혼입 사용할 경우 생활계 복합재질 폐플라스틱의 물질재활용 제품인 인삼재배시설용 지주대의 품질기준인 GR M 3093-2021을 안정적으로 만족시키는 것으로 나타났다.
