随着城市建设的发展,城市的改建和旧有建筑物的拆除工作量越来越多,特别是一些钢筋混凝土结构物,常常需要用炸药进行爆破。这种方法将产生很大的振动、噪声和冲击波,同时还产生大量的飞石、粉尘和有害气体,施工操作很不安全,对周围环境污染很大。这在建筑物密集的城市中进行是很不适宜的。近年来,研制成功的静态膨胀破碎剂,是一种非爆炸性破碎剂,应用它来进行建筑物破碎处理,可避免爆炸法的一系列缺点,是一种既安全又无公害的高效率 With the development of urban construction, more and more city reconstructions and demolition of old buildings have been carried out. In particular, some reinforced concrete structures often require blasting with explosives. This method will produce a lot of vibration, noise and shock waves, but also produce a lot of flying stones, dust and harmful gases, the construction operation is very unsafe, and the surrounding environment is very polluted. This is very inappropriate in a densely-built city. In recent years, the successfully developed static expansive crushing agent is a non-explosive crushing agent. Using it to crush the building can avoid a series of shortcomings of the explosion method. It is a safe and pollution-free high efficiency.
