摘　　要：尝试通过通入惰性气体的高温无氧热解法,对防弹衣或防弹头盔等警用装备中的芳纶无纬布防弹层进行资源化处置和再生利用。结果表明,利用芳纶纤维和胶黏剂热解温度的不同分别进行分解,既可以破坏原有装备形态,使报废装备无法重新流通使用,又使其分解产生可燃气体或提取可二次利用的纤维丝,达到资源化处置警用防弹装备的目的;结合仿真模拟和实验比对分析得出热解的最佳温度约为410℃和最佳热解位置。This work attempts to conduct the resourceful disposal and recycling utilization of aramid weftless fabric ballistic layer in police equipment such as bullet-proof vests or helmets through high-temperature anaerobic pyrolysis with the passage of inert gas. The decomposition of the aramid fibre and adhesive at different pyrolysis temperatures not only destroys the original equipment form and prevents the end-of-life equipment from being recirculated for use,but also makes it decompose to produce flammable gas or extract the fibre yarn that could be used twice. This leads to the achievement of the purpose for the resourceful disposal of police ballistic protection equipment. Combined to the simulation and experimental analysis,an optimal temperature range of 410 ℃ and an optimal location of pyrolysis were obtained.
