Advantages of CO2 fracturing products for municipal construction enterprises

　　Unlike traditional explosives, carbon dioxide fracturing does 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 equipment, as a physical fracturing device, has no negative effects and has high safety performance. At the same time, because this product does not belong to civilian explosives (explosives) products, it is not subject to the many restrictions of civilian explosives (explosives) product control, and the product has a wide range of applications;

　　1. In municipal engineering and related construction (bridge and road construction, site leveling, real estate development and construction), the use of blasting machines is time-consuming and costly; using carbon dioxide for fracturing (rock breaking) can greatly improve work efficiency and effectively reduce construction costs;

　　2. In areas where the use of explosives is not permitted, carbon dioxide can be used for fracturing construction. Such as urban areas, residential areas, factory areas, schools, enterprises, alongside railways, under high-voltage power lines, water sources, scenic areas, and cultural relics, etc.

　　3. Carbon dioxide fracturing can be directional and time-delayed. During the implementation process, the vibration is small, there is no destructive vibration or shock wave, there is no destructive impact on the surrounding environment, and there is no problem of disturbing the public;

　　4. The use of carbon dioxide fracturing is not affected by holidays and can be carried out normally (New Year's Day, Spring Festival, May Day, Dragon Boat Festival, Mid-Autumn Festival, National Day, etc.), and during important guarantee periods (junior and senior high school entrance examinations, college entrance examinations, important meetings, important government and local activities, etc.).

　　5. Carbon dioxide fracturing has no dust or flying stones, does not produce toxic and harmful gases, has a short shelter distance, can quickly return to the working face, and can operate continuously;

　　6. The thermal reaction process is carried out in the closed cavity of the pipe, low-temperature fracturing, and the sprayed CO2 has the effect of suppressing explosions and flame retardancy, and will not ignite combustible gases;

　　7. 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 completion only takes 4 milliseconds. There are no dud shots during the implementation process, and no blasting inspection is required;

　　8. No blasting warehouse is needed, the management is simple, the operation is easy to learn, there are few operators, and no professional personnel are required for guarding;

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