摘要
为了促进国内烟火切割技术的发展。比较了美国和中国烟火切割技术的研究历史、现状和发展趋势。结果表明,烟火切割的原理主要包括金属射流原理和化学腐蚀原理,烟火药主要以铝热剂为基础同时添加含卤素的聚合物。切割炬已经可以手持,并可以进行水下切割。切割炬上的喷嘴可以起到使能量集中的作用,切割炬必须具有安全泄压结构。烟火切割技术在抢险救援、弹药销毁等方面有着广泛的应用,在国内大力开展烟火切割技术研究很有必要。
The research history,current situation and development trends of pyrotechnic cutting technology in the United States and China were introduced.Pyrotechnic cutting principles include metal-jet principle and chemical corrosion principle,Pyrotechnical compounds mainly focus on thermite at the same time adding halogen-containing polymers.Cutting torch already can be held by hand,and could be carried out underwater.The nozzle on cutting torch can concentrate energy,and cutting torches have pressure relief structure for security.Pyrotechnic cutting technology has a wide range of applications in disaster rescue,ammunition destruction and so on.
