Abstract
Recently many scientists have tried to synthesize biodegradable polymers due to durable and non-biodegradable products of conventional synthetic plastics when these were wasted in nature. So to reuse the wastepapers for biodegradable polymer resources, ONP (old newsprint), OCC (old corrugated containerbpard) were carried out by the pretreatment of chlorinite, hypochlorite and oxygen-alkali treatment conditions. For manufacturing of biodegradable polymer with wastepaper, this study performed to investigate change of chemical components and optimal pretreatment condition. The summarized results in this study were as follows: Lignin content in ONP and OCC was was higher than in MOW and ash content was the highest in MOW. More amount of ash components were reduced by wet defiberation than by dry defiberation. Wet defiberation fiber are better than dry defiberated fiber in chemical pretreatment condition for wastepapers, and the best result was obtained in the condition of sodium chlorite at
최근 들어 범용 플라스틱계 고분자의 환경오염이 심각한 사회적 문제를 유발함에 따라 많은 연구자들이 생분해성 고분자 소재 개발에 관한 연구를 시행하고 있으며, 본 연구에서는 폐지를 이용한 생분해성 고분자물질의 제조를 위하여 폐지의 화학적 성상 및 최적 전처리조건을 검토하기 위해 시행하였고, 그 결과는 다음과 같다. 각 공시재료별 화학적 조성분 분석 결과 신문폐지와 골판폐지의 리그닌 함량이 사무실 폐지에 비해 높게 나타났다. 또한 건식해리 펄프에 비해 습식해리 펄프의 회분 함량이 낮게 나타났다. 생분해성 고분자의 제조를 위해서는 반드시 폐지의 화학적 전처리가 요구되며, 습식해리 시료가 건식해리 시료에 비해 전처리 효과가 우수하였다. 본 연구에서 행해진 화학적 전처리 중 아염소산나트륨으로 가온(
