Problems solved by technology

[0006] The detonating device with the above-mentioned structure has the following problems: 1. The thermal reactants to be filled in the detonating device need to be processed by mixing, mixing, coiling or bagging, and the filling process is time-consuming and labor-intensive. , high manufacturing cost; 2. In the process of filling the detonating device, the oxidant and reducing agent are prone to uneven mixing, resulting in low heat release efficiency; 3. The thermal reaction material needs to be mixed and filled in advance, and the temperature during transportation is high It is easy to cause combustion or explosion, and has a large safety hazard; 4. Due to the delay of the detonating material or other situations, it is easy to appear the situation of squibs, and it is impossible to judge the cause of the squibs, so the safety cannot be eliminated by rowing the squibs. Hidden danger; 5. The existing gas blaster detonation method uses solid activator to burn to generate high temperature, directly conducts heat to liquid carbon dioxide, makes liquid carbon dioxide vaporize and expand, and its heat absorption efficiency of liquid carbon dioxide is low
