      The advantages of carbon dioxide cracking products for municipal construction enterprises

      Unlike traditional explosives, carbon dioxide cracking does not produce shock waves, open flames, heat sources or various toxic and harmful gases resulting from chemical reactions. Applications have proved that the carbon dioxide fracturing device, as a physical fracturing equipment, has no negative effects at all and has a very high safety performance. Meanwhile, carbon dioxide is used for cracking. Since this product does not fall under the category of civil explosives (explosives), it is not subject to many restrictions on the control of civil explosives (explosives) products and has a wide range of applications. The specific advantages of carbon dioxide fracturing products are as follows:

      1. For municipal engineering and related construction (bridge and road building, site leveling, real estate development and construction), the use of blasting machines is not only time-consuming but also relatively costly. The use of carbon dioxide for fracturing (rock cracking) can greatly improve work efficiency and effectively reduce construction costs.

      2. In sections and areas where the use of explosives for construction is not permitted, carbon dioxide can be used for cracking construction. Such as urban areas, residential areas, factory areas, schools, enterprises, beside railways, under high-voltage towers, water sources, scenic spots and cultural relics and historic sites, etc.

      3. Carbon dioxide fracturing can be either directed or controlled in a delayed manner. During the implementation process, it generates little vibration, has no destructive vibration or shock waves, has no destructive impact on the surrounding environment, and does not cause disturbance to residents.

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

      5. When carbon dioxide causes cracking, there is no dust or flying stones, no toxic or harmful gases are produced, the distance to avoid blasting is short, and it can quickly return to the working face for continuous operation.

      6. The thermal reaction process takes place in the inner cavity of a closed tube, causing cracking at low temperatures. The CO2 ejected has the functions of suppressing explosions and flame retardancy, and will not ignite flammable gases.

      7. Neither vibration nor impact can stimulate the heating device, so it has a relatively high level of safety during filling, transportation and storage. Moreover, the injection of liquid carbon dioxide only takes 1 to 3 minutes, and the cracking process is completed in just 4 milliseconds. During the implementation, there is no mute cannon and no cannon inspection is required.

      8. No need for a pyrotechnic depot, simple management, easy to learn operation, few operators, and no need for professional personnel to be on duty.

      9. The cracking ability is controllable, and the energy level can be set according to different usage environments and objects.
