Plastics are an important usable energy resource. The energy stored in them can be used as fuel in modified high-energy materials. Such use makes it possible to simultaneously dispose of waste plastics and improve the energy properties of modified explosives. The simplest material that is used for this purpose is ammonium nitrate fuel oil (ANFO)-commonly used in rock mining. Tests carried out in the Trauzl lead block test assessing the strength of explosive have shown that, with the right amount of certain polymers, similar or even better properties-energy performance-can be achieved by replacing the fuel oil in ANFO. In turn, tests conducted on the impact of plastic comminution on the assessment of the strength of high-energy material showed that a 1.0% addition of polypropylene, polyethylene or polyurethane significantly increases the strength with reference to ANFO. The test results are of practical importance and, for a more complete assessment of the suitability of polymers for use, it will be advisable to conduct further studies of the properties of high-energy materials with selected plastics.
塑料是一种重要的可用能源资源。它们所储存的能量可在改性高能材料中用作燃料。这种用途使得同时处理废塑料并改善改性炸药的能量特性成为可能。用于此目的的最简单材料是硝酸铵燃油（ANFO）——常用于岩石开采。在Trauzl铅柱试验中进行的评估炸药强度的测试表明，加入适量的某些聚合物，通过替代ANFO中的燃油，可以实现相似甚至更好的性能——能量性能。反过来，关于塑料粉碎对高能材料强度评估影响的测试表明，添加1.0%的聚丙烯、聚乙烯或聚氨酯相对于ANFO能显著提高强度。测试结果具有实际重要性，为了更全面地评估聚合物的适用性，对选定塑料的高能材料特性进行进一步研究将是明智的。
