乘员舱非金属材料脱气物的GC／MS分析及评价

GC/MS Analysis and Evaluation of Gassing Products from Crew Cabin Nonmetallic Materials

应用ＧＣ／ＭＳ联机和顶空／浓缩采样技术，对２１种国产聚合材料的热脱气产物进行了检测，定性鉴定出６９种化学成分，讨论了脱气物的来源和材料脱气的毒理学特征，初步评价了材料的卫生性能并提出合理使用聚合材料的建议，为评价和选用聚合材料提供一些实验依据。

The thermal off-gassing products from twenty one types of national polymel materials were monitored using GC/MS technique as well as headspace/concentration sampling technique. The sixty nine chemcial componets were identified in all. The sources of the outgas products and toxicological characteristics of the materials were discussed.Hygienic property of the materials were evaluated and the proposition for making rational use of the materials was advanced.These will provide important basis to evaluate and select polymer materials.
