- 详细技术说明
- Researchers at INL havedeveloped methods for rendering CEMs inherently resistant to accidentalignition by fire while maintaining normal functionality under intentional activation.This is achieved by incorporating an additive that breaks down at the lowertemperatures and heating rates associated with a fire, rendering the CEM incapableof detonation. The additive doesn’t have time to break down under the muchhigher heating rates of intentional ignition.

TECHNOLOGYMARKETING SUMMARY:
Composite energeticmaterials (CEM) are mixtures of discretely separated fuel and oxidizermaterials that combine to produce highly exothermic reactions. CEMs are highlycustomizable, making them extremely useful for many applications, includingpyrotechnics, primers for high explosives, and fuels for thrusters, and aidsfor welding. Their widespread integration in industry makes their potential forunintentional ignition a serious safety concern.
Accidental explosions inpyrotechnic plants and markets have resulted in several catastrophic eventscausing significant loss of life and property, and unplanned detonationcontinues to be a major risk associated with transport, handling, and storageof these materials. Current methods for mitigating that risk include limitingquantities and carefully guarding transport and usage.
