山西晋安化工厂研制一种 JA 型混凝土破碎剂,这种破碎剂是由某种可燃金属和氧化剂按一定配合比组成,在密闭容器内点火后发生化学反应,产生静态高温高压来破碎或切割混凝土和岩石。施工工艺基本上与普通炸药相同。它既能达到炸药的功效,而又排除了炸药爆破所带来的弊害。与炸药相比,它具有振动小、噪音小、无飞石、无气体污染、使用方便、施工周期短、便于运输储存、安全可靠等优点,适用于在城 Shanxi Jinan Chemical Factory developed a JA concrete breaker, which is composed of a combustible metal and an oxidizer at a certain mixing ratio. After ignition in a closed container, a chemical reaction occurs, resulting in static high temperature and high pressure to crush or cut. Concrete and rocks. The construction process is basically the same as ordinary explosives. It can not only achieve the effect of explosives, but also ruled out the harm caused by blasting explosives. Compared with explosives, it has the advantages of small vibration, low noise, no flying rocks, no gas pollution, easy to use, short construction period, convenient transportation and storage, and safety and reliability. It is suitable for use in cities.
