摘要
对鉴定力学环境试验后氧化剂路氟塑料贮囊破裂机理进行了分析,并从熔融指数、六氟丙烯含量及淬火工艺三方面对氟塑料材料耐开裂性能进行研究与论述。研究表明,通过调整熔融指数、六氟丙烯含量及淬火工艺等参数,可以生产出高强度、高耐开裂性的材料,满足氟塑料贮囊的使用要求。
The fracture mechanism of fluoroplastic bladders used at oxidizer path was analyzed after mechanics qualification environment testing.The anti-crack performance of fluoroplastic is studied and discussed in terms of melt index,hexafluoropropene content and quenching process.The results indicate that the material with high strength and anti-crack performance can be produced by adjusting the parameters of melt index,hexafluoropropene content and quenching process,and can meet the application requirements of fluoroplastic bladders.
