What are the obvious advantages of CO2 fracturing tools compared to traditional explosives?

　　Unlike traditional explosives, carbon dioxide fracturing devices do not produce shock waves, open flames, heat sources, or various toxic and harmful gases produced by chemical reactions. Applications have proven that carbon dioxide fracturing devices, as a physical fracturing device, have no negative effects and high safety performance.

　　1. The thermal reaction process takes place in the closed cavity of the pipe, low-temperature fracturing, and the ejected CO2 has the effect of suppressing explosions and flame retardancy, and will not ignite combustible gases;

　　2. It can be used for directional fracturing and delayed control, especially in special environments (such as residential areas, tunnels, subways, underground, etc.). During the implementation process, the vibration is small, there is no destructive vibration and shock wave, and there is no destructive impact on the surrounding environment;

　　3. Neither vibration nor impact can trigger the heating device, so the filling, transportation, and storage have high safety; and the liquid carbon dioxide injection only takes 1-3 minutes, and the fracturing to the end only takes 4 milliseconds. There are no dud shots during the implementation process, and no inspection is required;

　　4. No pyrotechnic warehouse is needed, management is simple, operation is easy to learn, fewer operators are needed, and no professional personnel are required for guarding;

　　5. The fracturing capacity is controllable, and the energy level can be set according to the different use environment and objects;

　　6. There is no dust or flying stones during fracturing, no toxic and harmful gases are produced, the distance to avoid the explosion is short, and the working face can be quickly returned to for continuous operation;

　　7. In stone mining, it does not damage the texture structure, and the material yield and efficiency are higher.
