Abstract
Description
도 2는 대략 2일 후 산소 투과를 초과하는 산소 제거를 나타내는, 수분-트리거링된 10% 첨가제를 함유하는 사출-성형된 시퍼 구조 내부의 시간 경과에 따른 산소 공기 포화를 나타낸다.
도 3은 선형 회귀선과 일치하는 정상-상태 투과 영역을 갖는 트리거링되지 않은 첨가제-함유 샘플로부터 제조된 시퍼를 통한 산소 투과를 제시한다. 투과는 회귀선의 기울기 (시간당 % 산소 증가의 단위를 가짐)인, b[1]로부터 계산된다. 도 3에서 값 b[o]는 y-절편을 나타내고 r2는 상관 계수를 제시한다.
도 4는 선형 회귀선과 일치하는 정상-상태 투과 영역을 갖는 버진 HDPE (첨가제 없음)로부터 제조된 시퍼를 통한 산소 투과를 제시한다. 투과는 회귀선의 기울기 (시간당 %산소 증가 단위를 가짐)인, b[1]로부터 계산된다. 도 4에서 값 b[o]는 y-절편을 나타내고 r2는 상관 계수를 제시한다.
도 5는 버진, 트리거링되지 않은, 및 트리거링된 샘플에 대한 시간 경과에 따른 공기 포화의 그래프이다.
