Abstract
Description
시차 주사 열량계는 시차 주사 열량계의 조작 안내서에 기술된 바와 같이 인듐 금속 기준물질을 사용하여 보정하였고, 기저선 보정을 수행하였다. 물질 샘플을 시험을 위한 시차 주사 열량계의 시험 챔버에 위치시키고, 기준으로서 빈 접시를 사용하였다. 모든 시험은 시험 챔버에서 55㎤/분의 질소(공업용)로 퍼징(purging)하면서 실행하였다. 수지 펠렛 샘플의 경우, 가열 및 냉각 프로그램은, 챔버를 -25℃로 평형화하는 것으로 시작하여, 10℃/분의 가열 속도로 200℃까지 가열하는 제1 가열 기간, 그 다음 200℃에서 3분동안 샘플의 평형화, 그 다음 20℃/분의 냉각 속도로 -25℃까지 냉각시키는 제1 냉각 기간, 그 다음 -25℃에서 3분동안 샘플의 평형화, 그 다음 10℃/분의 가열 속도로 200℃의 온도로 가열하는 제2 가열 기간으로 끝나는 2주기 시험이었다. 섬유 샘플의 경우, 가열 및 냉각 프로그램은, 챔버를 -25℃로 평형화하는 것으로 시작하여, 20℃/분의 가열 속도로 200℃까지 가열하는 가열 기간, 그 다음 200℃에서 3분동안 샘플의 평형화, 그 다음 10℃/분의 냉각 속도로 -25℃까지 냉각시키는 냉각 기간으로 끝나는 1주기 시험이었다. 모든 시험은 시험 챔버에서 55㎤/분의 질소(공업용)로 퍼징하면서 실행하였다.
