弹药在生产、储存、运输和装卸过程中的无意起爆是爆炸危险的主要来源之一。这种意外引爆炸药的行为被称为交感引爆，即一个炸药单元（或弹头）的引爆引发另一个炸药单元的引爆，随后开始连锁反应。因此，对运输或存储容器内的弹性轻质缓冲分离系统的需求正在增加。本文介绍了一种具有成本效益的轻质硬质聚氨酯泡沫（RPF）分离系统的开发和测试。所讨论的缩比间隙试验方法被用作一种实用的工具，以研究由作为爆炸波衰减介质的RPF产生的爆炸波对受体炸药装药的起爆性。不同的RPF试样制备不同的密度和粉土颗粒的混合比例从0%（无粉土）到30%。研究结果表明，RPF作为一种轻量化的成本效益技术，能够将爆炸波对受体炸药的影响衰减到安全水平。
The unintentional initiation of munitions during production, storage, transportation, and handling is among the main sources of explosive hazard. Such unintentional initiation of explosives is termed sympathetic detonation, in which the detonation of a single explosive unit (or warhead) triggers the detonation of another, and subsequently starts a chain reaction. Because of this, the demand for resilient lightweight ammunition-separation systems within shipping or storage containers is increasing. This paper presents the development and testing of a cost-effective lightweight rigid polyurethane foam (RPF) separation system. The scaled gap test approach discussed is used as a practical tool to investigate the initiability of acceptor explosive charges by a blast wave generated from donor charges through the RPF as a blast wave attenuation medium. Different RPF specimens were prepared with different densities and silt particle mix ratios ranging from 0% (no silt) to 30%. The study results demonstrate the capability of the RPF as a lightweight cost-effective technique to attenuate the blast wave effects on acceptor explosives to safe levels.
