一引言爆破片是近年来发展起来的一种压力系统防超压安全泄放装置。由于它具有密闭性强(无泄漏),动作灵敏、准确、可靠,排放面积大小不限,适应面广(如高温、高压、真空、强蚀等),结构简单,维护方便等突出特点,已被广泛用于化工、石油化工、医药、能源、军工等领域。国外爆破片技术的研究与制造历史已有50余年。例如美国BS&B安全系统公司,从1931年成立以来,即从事爆破片的开发与生产。但对其关键性的技术几乎是完全保密的,有价值的研究成果也不予公开。从国外定型产品来看,该技术已发展得比较成熟。在一些工业发达国 I. INTRODUCTION Bursting disc is a pressure system anti-overpressure safety relief device developed in recent years. Because it has a strong seal (no leakage), action sensitive, accurate, reliable, unlimited discharge area size, wide adaptation (such as high temperature, high pressure, vacuum, strong erosion, etc.), simple structure, Is widely used in chemical, petrochemical, medicine, energy, military and other fields. Foreign rupture disc technology research and manufacturing history of more than 50 years. For example, the United States BS & B Security Systems, from its inception in 1931, that is engaged in the development and production of rupture discs. But its key technology is almost completely confidential, valuable research results are not disclosed. From the stereotypes of foreign products point of view, the technology has developed more mature. In some industrialized countries
