摘要： 在真空热试验过程中进行了污染物的采集及成分分析试验。利用污染采集板收集污染物,丙酮溶液洗脱污染物,气相色谱-质谱联用方法对污染物进行成分分析。确定了整星热试验和太阳电池翼热试验中的主要污染物成分为硅氧烷和邻苯二甲酸酯,热试验中污染物甲基苯基硅氧烷可能来源于粘结剂。

Abstract: The contaminant collection and component identification tests were performed during the thermal vacuum tests.The witness plate was used to collect deposits,which was solved by acetone.The solution was analyzed by using GC/MS to identify compositions of the contaminants.Phthalate and siloxane were identified as the main contaminants in satellite thermal vacuum tests and solar array thermal vacuum tests.Possible source of methylphenylsiloxane in solar array thermal vacuum test may come from solar cell adhesive.
