| 中文摘要: |
| 对现阶段气体灭火剂（简称灭火剂）灭火系统常用的3种橡胶材料[丁腈橡胶（NBR）、高温硫化硅橡胶（HTV）和氟橡胶（FKM）]与3种新型高沸点灭火剂（Novec 1230，HCFO-1233zd和HFO-1336）进行常温-常压和高低温-高压浸泡试验，并对浸泡后橡胶的质量、体积、硬度和拉伸性能进行测试和分析，以研究3种橡胶与新型灭火剂的相容性。结果表
明：常温-常压下，3种橡胶均易溶胀，但不易发生溶解，3种橡胶均适用于Novec 1230贮存设备密封件，在不考虑体积变化的情况下NBR和HTV适用于HFO-1336贮存设备密封件；高低温-高压下，3种橡胶的溶解速率均增大，HCFO-1233zd贮存设备密封件不建议使用这3种橡胶，HFO-1336贮存设备密封件建议使用HTV，Novec 1230贮存设备密封件建议使用
NBR和HTV。 |
| 英文摘要: |
| In order to study the compatibility of rubber and new gas fire extinguishing agents，the immersion tests of three kinds of common rubber materials，nitrile rubber（NBR），high temperature vulcanized silicone rubber（HTV） and fluorine rubber（FKM），in three kinds of new fire extinguishing agents with high boiling point，Novec 1230，HCFO-1233zd and HFO-1336，were carried out under two kinds of conditions，normal temperature-normal pressure condition and high pressure condition with temperature cycles. The change of mass and volume，the hardness and tensile properties of the rubber after immersion were tested and analyzed. The results showed that under normal temperature-normal pressure condition，three kinds of rubber were swollen easily，but they could not be dissolved easily. They were all suitable for the seals of Novec 1230 storage equipment under normal temperature-normal pressure condition，and NBR and
HTV could also be used for the seals of HFO-1336 storage equipment if the volume change of the seals was not a prerequisite for the application. Under high pressure with temperature cycling condition，the dissolution rate of three kinds of rubber increased，three kinds of rubber were not suitable for the seals of HCFO-1233zd storage equipment，HTV could be used for the seals of HFO-1336 storage equipment，and NBR and HTV were suitable for the seals of Novec 1230 storage equipment. |
